Exactly how good is this Qualcomm Processor?

Seems with every smartphone that comes to the USA it gets some sort of Snapdragon Processor by Qualcomm and people do nothing but complain. So how does this Snapdragon S4 processor compare to every other dual-core processor out there and even the Tegra 3? Looked up some benchmarks and both seem to have their advantages and disadvantages. But what I really want to know is which one is better for real world performance, such as battery life, transitional effects, and launching apps. Couple people said Sense 4 is very smooth and "has LITTLE to no lag"? How does this processor display web pages in Chrome?

Read the thread "Those of your who are waiting too compare GSIII to HTC One X" in this forum. It only has about 6 pages but has a ton of information. Short answer is that the Qualcomm chip kicks serious ass.

After reading through that thread I'm still not entirely clear. Seems the Tegra is better for gaming?

yes and no, the tegra 3 does have a better gpu so in theory, better games. however, game makers cater to the mass. most androids that are active are mid-range, android 2.2 or 2.3, have a resolution of 480x800, and last years (or older) processors. although most will be made to work on the t3 and s4, it will be compatibility issues, not optimization. nvidia will have a couple games "t3 only" but even those will be made to work on other phones. now that ics is cleaning up some of the splintering of apps, we'll see some better options on both fields.
in short, yes the t3 is a better gaming chip. but for the battery life, games available, and current bugs i would suggest the s4. i may change my mind when the refreshs come out q3-4, we'll see.

Correct. However, most games are not optimized to utilize the Tegra to its fullest potential. That should change by the end of the year. The other point is that the S4 is just as good as the Tegra un terms of gaming performance. IMO, you should decide between these 2 processors by looking at the main area where the S4 truly has the advantage thus far, and that is battery life. So far, the battery life advantage goes to the S4. Just read the battery life threads in this forum and for the international X. It took a few updates to the Transformer Prime to start having pretty good battery life. The One X, will get better in that department with a couple more updates for battery optimization. The S4 starts with great battery life and will get even better in that department.

I say the snapdragon S4 is a better chip right now. The tegra 3 gpu is great and with the tegra zone games it really looks great. But he 4 cores CPU is really for heavy multitasking so you candivise the work between all four cores. They are A9 cores vs the custom qualcomm which is close to A15. It mans that for single threaded task and multi threaded task the snapdragon will whoop tegra 3' ass. Opening an app, scrolling through that app sect... also browser performance is slightly better on the qualcomm chip. Basically tegra 3 can do lots of things at the same time with decent speed vs the S4 chip which can do 1 or few more things at lighting speed.

The S4 is almost 2x faster than any other dual core out there. Anandtech did a few nice articles on the S4, including benchmarks vs tegra 3.
In real use, the S4 should be much better, because not all apps are multithreaded for 4 cores. The S4 completely kicks the Tegra 3's ass in singlethreaded benchmarks. I also expect the S4 to be better at power management, because it is made on 28nm node, instead of 40 nm, so its more compact and efficient.

About 23 I'd say

Sadly, can't do much for the formatting. Enjoy.
The difference in DMIP's is where the S4 really whomps on the T3. All the T3 has going for it at the moment is it's GPU. If you don't care about some additional gaming prowess, the S4 is the way to go.

Just to add to that and to be fair, S4 is at around 7000 at antutu benchmark while tegra 3 is at around 10000. I still prefer the S4

Eh...
It wins in 1 benchmark specifically enabled to take advantage of more than 2 cores. So if you want to play tegrazone games and have some basic lag, the T3 is for you. If you want to have a near flawless phone experience, and have decreased graphical performance in some wanna be console games, then the S4 is the way to go.

Actually you wont really notice the lack of graphics performance on the snapdragon s4. Its about 10% slower in most benchmarks but outperforms the tegra3 in a few as well. However i have a sensation xl with the adreno 205 which is only a quarter as fast as the adreno 225 and all games including deadspace, frontline, blood glory runs smoothly on it. To say the snapdragon s4 is inferior because of the slower Adreno 225 is really nit picking to me. For me bigger reason to choose one graphics chip over another is flash performance and this is where the exynos mali 400 kicks the adreno 225 in the balls. It handles 1080p youtube videos in browser without a hiccup while the 225 chokes even on 720p content.

Let me answer this. How good is it? More than good enough. Almost all apps and games are catered to weaker phones so the T3 and S4 are both more than good enough.
And my two cents, the S4 beats tegra 3

Let me start by saying I'm not a pro when it comes to electronics but I do have an understanding on the subject.
The thing to realize about these processors, and most other processors available today, is that the s4 is based on the cortex a15 while the tegra 3 along with the new Samsung are based on the a9. The a15, at the same Hz and die size is 40% faster than the a9.
S4 = dual core Cortex A15 @ 1.5GHz - 28NM
Tegra3 = quad core Cortex A9 @ 1.5GHz - 40NM
Exynos 4(Samsung) = quad core Cortex A9 @ 1.5GHz - 32NM
S4 so far, in theory, is 40% faster per core, but having two less. Individual apps will run faster unless they utilize all four cores on the tegra3. Because the s4 has a smaller die size, it will consume less energy per core.
The actual technology behind these chips that the manufacturers come up with will also affect the performance output, but the general idea is there. Hope that helps to understand a little better how the two chips will differ in performance.

The S4 compared to the Tegra3 says it all. dualcore that beats a quadcore in almost everything.

Intel released the first native dual core processor in 2006 and shortly thereafter released a quad core which was basically two dual cores fused together (this is what current ARM quads are like).
That was 6 years ago and these days pretty much all new desktop computers come with quad cores while laptops mostly stick with dual. Laptops make up the biggest share of PC sales so for your everyday PC usage, you'll be more than comfortable with a dual core.
You really can't assume mobile SoCs will follow the same path, but it's definitely something to consider. I think dual core A15-based SoCs will still rule the day this year and next at the very least.

I was really on the fence about the X or the XL. But the S4 got me. Not having 32GB is already bugging me. But the efficiency (and my grandfathered unlimited data paired with Google Music) is definitely worth the sacrifice. Very happy so far! Streaming Slacker, while connected to my A2DP stereo, running GPS was great. I'm not a huge gamer though. I miss Super Mario Bros being the hottest thing!

correct me if im wrong but all 3 are A9 based including the S4. the first A15 will be the Exynos 5250, a dual core.

This is inaccurate.
The Exynos 4 and the Tegra 3 are based on the ARM A9 reference design.
The Qualcomm Snapdragon S4 is "roughly equivalent" to the A15, but not based on the A15. The same was true for Qualcomm's old S3 (which was equivalent to something between the A8 and A9 design)
One thing that most people don't realize is that Qualcomm is one of the very few companies that designs its own processors based on the ARM instruction set, and while S4's is similar to the A15 in terms of architecture, it's actually arguably better than the ARM reference design (e.g. asynchronous clocking of each core which is a better design than the big.LITTLE or +1 design).

Get ready for some blazing performance at low price by 2013

Mediatek which is famous for producing cheap SoC is reported to bring new mediatek 6588 quad core and mediatek 6583 dual core processors. While both processors will be clocked at abt 1.5-1.7 Ghz but what is really amazing is that they will be based on 28nm fabrication process. Yes you heard it right its 28 nm, the same as used in qualcomm snapdragon s4 krait processors. Performance of 28nm processor is already evident as one s which uses dual core krait processor easily defeats its bigger sibling one x in synthetic benchmarks which uses last generation quad core. Not to forget 28nm processors consumes less juice and runs a lot cooler.
So folks looking up for new phones might just decide to wait a bit longer.

Now some news for guys who are ready to empty up their pockets for some great technology. Samsung will be bringing new exynos SoC based on 20nm and 14nm fabrication process. The performance and battery life these chips will deliver can only be dreamt of . So guys a lot to come next year in terms of horse power.

Good news. Hopefully this will mean that the prices of the middle segment will drop further and further.
But i fear the extra performance and Ghz will completely nullify the decreased power consumption.
I for one would like to see a phone in 2013 with the same cpu power as the phones of today, but with a vastly increase battery life..

yup the prices will decrease further and the better part is quad core will become more affordable and as for battery life, its gonna get better with more refined manufacturing process as compared to current quad core.

[NEWS]Samsung announced the Heterogeneous Multi-Processing (HMP) for Exynos 5 Octa

http://www.samsung.com/global/busin...eterogeneous_Multi_Processing_Capability.html
This is breaking good news for us, though it's still unclear if it's for 5420 only or can be implemented into 5410 through update as well.
If you've been paying attention, you know that the Exynos 5 Octa packs a serious punch when it comes to processing power and energy efficiency. Now, the team at Samsung has made the Exynos 5 Octa even better with the introduction of a new Heterogeneous Multi-Processing (HMP) solution.
Overview of big.LITTLE Technology
Before we jump into the benefits of HMP, let's take a step back and go over the basics ofARM® big.LITTLE technology. In the Exynos 5 Octa, eight CPU cores are responsible for everything from browsing the web to playing your favorite game on your 5 Octa-powered mobile device. Four "big" 1.8GHz ARM® Cortex™-A15 cores handle intensive tasks like graphically rich gaming or HD video playback. Less intensive tasks like e-mail or text functions are tackled by four "LITTLE" 1.3GHz Cortex™-A7 cores. By dividing and conquering tasks and assigning them to the proper CPU cores, big.LITTLE technology maximizes performance while minimizing power loss.
HMP Makes big.LITTLE Technology Even Better
Now this is where HMP comes into play. Like a sports team, big.LITTLE technology relies on a software "coach" to call the plays and assign tasks to each core. In a basic implementation of big.LITTLE technology, this "coach" would alternate between using "big" and "LITTLE" CPU cores based on the computational intensity of any given task, and one core or cluster of cores would remain inactive while its counterpart was engaged.
With HMP, all eight of the CPU cores in the Exynos 5 Octa can be utilized at the same time. This provides users with an unlimited mobile experience in the current mobile environment and also paves the way for more advanced and complex functionality in the future. HMP is extremely versatile. Using a global load balancing scheduler, HMP can assign a single core to handle a task with low computational intensity in order to maximize power efficiency. On the flipside, HMP can also simultaneously utilize each of the eight individual cores in the 5 Octa to run multiple tasks in real time. The global load balancing scheduler pays attention to user workloads and will pull in the necessary available resources for the system to run flexibly and efficiently. By analyzing and assigning tasks,this highly complex software system maximizes efficiency by balancing CPU workload.
The result is the most advanced use of big.LITTLE technology to date and a huge leap forward for multi-processing capability in mobile devices. By allowing for the simultaneous operation of both "big" and "LITTLE" cores in the Exynos 5 Octa, Samsung offers an optimized HMP solution to the balancing act of maximizing mobile device capability while minimizing power loss.
Samsung has always been a leader in big.LITTLE technology, and this new Octa-core HMP solution is an industry first. HMP sets the stage for the future as mobile devices are increasingly called upon to handle complex and graphically rich tasks. Through this innovative solution, the benefits of big.LITTLE technology are maximized to their full potential. Get ready, because the future of mobile processing is evolving, and the Exynos 5 Octa with HMP is leading the way.

You get your point there, however I think that's not valid enough as when Sammy do their public announcements they will (of course) talk about the better things. Everything they talk about is "up to"
Anyway I'm not sure about this. I know @AndreiLux mentioned the core migration is impossible because flawed hardware, but HMP should be another story, I guess mostly it's about the Linux kernel. Let's just wait and see.

Hopefully they will release a refreshed version of the i9500? Probably not but here's hoping.

@AndreiLux sorry if i disturbed u but now just want to clarify few things because as we all know ur the master of this Exynos thingy...
"Samsung will enable the HMP solution for its Exynos 5 Octa in Q4 2013."
source: " http://www.sammobile.com/2013/09/10...ocessing-will-be-integrated-in-exynos-5-octa/ "
is it for i9500 or it is just for the new Note 3 powered by Exynos 5420 ?

Ohh. And why do you think some normal stuff would require anything more than a7 cores.. u understand that most off the apps on playstore would not require even 2 a5 cores at max logically or 4 a15s at half frequency.. so it doesnt matter that all 8 cores are online.. it only depends on how you use it.
For a power user its cherry over cake for others it is a great news for battery life..

Low multi-threadedness is a myth or a product of stupid programming. For one I'm making an application right now which parallelizes the whole UI loading and can make easily use of of 7+ threads scales pretty much infinitely if it's allowed to.
More cores don't cost any power, only die area. You gain tremendous dynamic range and power efficiency. Of course your theoretical peak power consumption goes up but you can just cap that with power management.
The Moto X is a good example of how a dual-core SoC can be less power efficient than a quad-core.

Okay understood. But honestly. If all the 8 cores are used how would anyone manage power efficiency?
A15s least frequency consumes higher amount of power than peak power consumption of A7s. Is not that so?
edit: I understood. More cores would cost only die area. They wont cost any power unless they are used more. What happens when die area is occupied more?

I dont think this will make a big difference in battery life. I think the display is the real power hungry in every android device. Also the android system itself.
Smart phone maker should focus on making lighter and smaller battery but better power capacity.

From Sammobile:
Chinese manufacturer Meizu has some good news. According to Meizu, HMP can be implemented through a software upgrade, and will be made available to the MX3, its current flagship that uses the same Exynos chip as the Galaxy S4. This means that we should see Samsung doing the same for its own devices, and it could be the reason why the Korean manufacturer is only showing off the new eight-core capability without naming a new Exynos chipset.

In short, Meizu is saying that HMP is possible in 5410 Octa, as their MX3 uses it. So, is Meizu wrong?

Exynos Note 3 possibly won't get HMP update from Samsung

Bad news for fellow Exynos users.
http://www.phonearena.com/news/Note...t-core-performance-patch-says-Samsung_id47977
It seems that Exynos 5420 is capable of HMP but will get too hot for the chip to handle.
But the Samsung Engineer does mention that they would comment the HMP update only after a complete testing process to ensure trouble free operation.
Note 3 and Galaxy S4 are unlikely to receive the full octa-core power in their Exynos chipset versions, advised a chief technical expert from Samsung's Mobile Solutions department. Recently the company said that it is able to unleash all the eight cores working at once, which can bump performance significantly, compared to the maximum of four cores restriction we have now with Exynos 5 Octa in these handsets.
The thing is, the engineer comments, that even though Samsung can release a software patch that will allow both the quad-core Cortex-A15 set, and the frugal Cortex-A7 cores, to get together for a task, the thermal envelope of these Exynos chips hasn't been cut for the job.

Nah. HMP is the real thing. Said Andreilux
HMP is extremely useful for power efficiency because you can migrate stupidly faster than DVFS allows you to.

My question is, if there is so much problems in that chip then why he is selling these faulty chip...and why in india, asian and african small countries where government dont do anything agains this kind of behaviour...and costmers also ignoring these issue..which not good for future.
1 many problems in s4
2 sim locking
3 knockon
....many more ..and some may be coming soon
And now no HMP update for s4 or note 3 ...seems like samsung has over confident of their market share and profit...

Samsung wants to maximise profits by selling phones made with its in-house chip but is not able to integrate LTE in the chip. So, all it can do is to sell the phone with the Exynos chip in non-LTE areas.
But still, I think the Exynos is good too. It's CPU is damn powerful(considering a clock speed of only 1.9 Ghz)

Thermal problems are a poor excuse considering cluster migration is going to be much worse for thermals.
It's also a poor excuse considering HMP is best for power efficiency, meaning over all temperatures should be lower.
Unless they're worried that people will benchmark each thread and burn the chip out, but all they need to do is put thermal throttles and speed throttles with large A15 use.
I don't want to say Samsung are lazy because that's simply a stupid thing to say. Obviously all of this is very difficult and Samsung don't have the right combination and amount of time, talent and money to make it happen.
Core migration is going to be fine, anyway. If they ever bother with that.
Still disappointing anyway :/

Unless they're worried that people will benchmark each thread and burn the chip out, but all they need to do is put thermal throttles and speed throttles with large A15 use.
I don't want to say Samsung are lazy because that's simply a stupid thing to say. Obviously all of this is very difficult and Samsung don't have the right combination and amount of time, talent and money to make it happen.
Core migration is going to be fine, anyway. If they ever bother with that.
Still disappointing anyway :/

They have the Linaro team to do the work. They have already accomplished it but it has been shown off with only a prototype tablet.

If its true, then its very dissapointing step from Samsung
My question is, if there is so much problems in that chip then why he is selling these faulty chip...and why in india, asian and african small countries where government dont do anything agains this kind of behaviour...and costmers also ignoring these issue..which not good for future.
1 many problems in s4
2 sim locking
3 knockon
....many more ..and some may be coming soon
And now no HMP update for s4 or note 3 ...seems like samsung has over confident of their market share and profit...
Isnt this is kind of monopoly???

Well, someone write a news without any confermation and users say it's good
So.. now.. i'm going to write a news.. santa is real! And all beleave in it..
Too many sheeps in the world
Big little is over any other arch.. it has the best efficiency ever.. and will have it with hmp..
Yup, if you turn on all 8 cores in maxfreq for 10 minutes.. phone burns.. but.. the logic of big little is: use low power cores (A7) for low tasks.. use high power cores (a15) for hugh tasks..
Than.. now you are using the cluater migration, it has 2 "bugs"
1) all cluster switch, so, is alminented the A15 even if it's not necessary, it happes when 1 core goes to A15
2) the switch from 2 clusters blocks computation for little time
The core migration fix the first problem of cluster migration
The hmp fix each 2 "problems"
So.. if cluater migration is good.. core migration is better, and hmp is better and better
Hmp has high overheating? Well, so n3 with cluster will have more overheating.. all with n3 has this issue?
for me.. all of you use too less the brain.. brain is a muscle.. use it!

I do not find thermal envelope explanation for HMP logical. Cluster Migration switches all the cores to A15 even when one thread requires power hence this design is more battery hungry. If Samsung is really worried about crossing thermal envelope, then they can implement something like Intel has done which they call it Turbo Boost. They can effectively reduce max clock speed to 1.5 GHz when all A15 are running but allow it to run to 1.9 GHz when only 1 or two threads are running.
If Samsung refuses to do so, I hope developers find ways to unlock HMP. It is not that I need 8 cores running simultaneously when my laptop hums at 1.3GHz in dual core mode, but when Samsung teases us and there is treasure hidden ready for unlocking, then it is just human nature to want MORE.

voice of my heart
Absolutely right brother. The die hard snapdragon fans can not digest the Exynos big Little processing and just throwing out rumors and I am really shocked how people believe it. I saw in many discussions that readers and mostly writers were not even software or hardware literate they were just speaking and forwarding the rumors. Actually due to lack of sdk from Samsung for exynos the third party custom rom writers can not do much in exynos as they were able to do in snapdragon so this makes them angry and they spread rumors. I have note 3 SM900 exynos and previously I had s4 exynos one. Did not face any problem in s4 ever and it's my 4th day with note 3 and going great so far. In my thinking the little big processing is better than all 8 cores working at the same time and people should see that the big a15 quad core 1.9 ghz gave very very closer benchmarks test results to Snapdragon 800 2.3 ghz and some were higher. People don't understand the chip architecture and just play on rumors.

People doesen't understand what is an hotplug and how it works
The real goal of that arch is called "power gating".. simply it's a technique developed by intel witch AUTO shuts down transistors if those are not in use..
The hotplug uses a software decision to shut down cores.. it's not hardware..
the difference?
Simply, for linux, all cores are everytime turned on, even if the transistors of the core are shutted down.. that's prevent time spent to re-schedule the tasks.. and sure.. linux is a multithreading kernel, it means, more core = more parallelization = less frequency = less power usage
That's the real goal of big.little!
And you understand, if there are 8 cores.. tasks will be shared on more cores, it means it has the best efficiency ever
An ex.. phone ALWAYS have low tasks to be compilet to permit the phone using.. as like the audio task, video task, or, wireless taks.. well, why use an high performance arch for low performance tasks? That's why arm creates A7..
CORTEX.A7 has the best efficiency ever.. so.. the same task in a cortexA7 is compiled with LESS ENERGY than other arch.. so.. it's a perfect way to preserve energy
Sure, A7 is not a performance arch, that's why arm choses to create the A15.. when tasks are too high to be compiled with an A7.. system auto switch task on a A15.. so.. the goal is.. low tasks in A7 (best efficiency) and high tasks in A15 (best performance)
Mix best efficiency + best performance = best arch :thumbup:

Got a feeling they're testing the HMP tech / heat / performance / power consump in NOTE 3 already .........
They were brave enough to have it on display at an exhibition ..... the update seems promising from what I can see!
On the "tune.pk" site there's a "video 1058551" showing "Samsung-Exynos5420-HMP-bigLITTLE-demo" with all 8-cores running!
Hoping to see some actual benchmarks so we know what the before / after results are like!!!

I'd be inclined to agree with you. The Lite/Neo Note 3 has it enabled for all 6 cores apparently according to Sammobile

The lady from Samsung and Samsung wasnt hiding the Note3 device either ……
My contract is up soon ……
I hope benchmarks show up soon so I can get an idea of either the LTE or 3G one to get!

If you see some of the tweets of SamsungExynos on twitter here https://twitter.com/SamsungExynos it's easy to have a wild guess HMP will be soon released, just a wild guess though looking at their tweets.

5260 in note3 lite is obbly to be used with hmp.. why?
Cluster and core migrations may have the equal numbers of cores for each clusters, or kernel code won't works
I don't think if samsung will release hmp for the n900 or not.. the only thing i could say is: if samsung will relase a good source code.. I will extract the hmp from the note3 lite code , modify, and add it in my own kernel build.. and this for all kernel modders..
sure, i hope for a direct hmp upgrade by samsung, it will be better, but, we'll do all to try to run it..
I tryed to compile a code takken from internet witch tryes to load hmp.. but.. no possibilities due to an incompatibility with too mouch dependencies of the kernel code, traduct, actual source code is RUBBISH!
We are running universal drivers without any CCI code nor the real base of hmp..
source code core and cluster migration were writes TWO YEARS AGO!
We are runnin a code wroted for the 5410!! Not the 5420!!
That's why our exy suks compared to hmp features!

**** you samsung

Why do we want HMP activated ? The Android OS is not that advanced to be able to manage heat & conserve batteries even on KitKat. Enabling HMP will only ruin the phone hardware and shorting its age. Decision must have been made with careful reasonings.

PCMark: Note3 out-performs Note4

See benchmark details here
Top scores....
Note 3: 5130
Note 4: 4942

Duh...
Quad-core 1.3 GHz Cortex-A53 & Quad-core 1.9 GHz Cortex-A57 (SM-N910C)
quad-core 1.3 GHz Cortex-A7 & Quad-core 1.9 GHz Cortex-A15 (N9000)
The Exynos CPU in the N3 and N4 hava exactly the same speed... And yet the N9005 only has a 1920x1080 screen, whereas the Note 4 has to render 2560x1440.
Thank you for proving why I absolutely hate Exynos.
I'd like to know the Snapdragon variants. Since the Note 4 does have a significantly more powerful Snapdragon CPU, and the Snapdragon is the 80% of the market model, the Exynos is only for lower markets.
Quad-core 2.7 GHz Krait 450 (SM-N910S)
Quad-core 2.3 GHz Krait 400 (N9005)

But the Exynos in the Note 4 is pretty awesome already:

Good things are to come with the one in the Galaxy S6.

If you would run the PCMark test yourselves and post the results, that would be great!!
Thanks

If a market sells less or requires less high-level hardware due to an older, less sophisticated network system, it's considered a lower market. The demand and proceeds are lower compared to the high-selling markets, thus the word lower.
That's not a personal attempt at insult, it's a corporate definition.
Until 4G was rolled out, the Netherlands was one of those lower markets. (Though, frankly, I still consider it as such..) In the days of the S3, every non-US country was considered a lower market.
(Besides, I'm a sociopath, I don't do emotional )

Marketing aside: Temasek's CM12 + arter97 kernel + data&cache partitions in f2fs.
The phone is superfast as hell, but benchmark result was this:

Times are changing, for the worse and for better, i know it makes no sense, but so doesnt sammy.
They seem to drop Snapdragon, and with 810 in sight (ignored too), Exynos is going for a PR fight with overheating accusations, and being the sucky ones in performance and the best in sales (Samsung generally), they just made their phones even less open to the people, HOWEVER...they are dropping bloat too.
As i said, they are making no sense.

Why don't you simply run the test yourself with the superior phone/network you have and let the results speak for themselves?
PCMark for android

4354 here UK note 3

If Samsung do end up dropping Qualcomm in their next generation of phones, my N9005 Note 3 will be my last Samsung for the foreseeable future. Exynos holds no interest for me, as it's closed source nature inevitably means little to no support for non-stock AOSP/CM roms. And the non-stock roms that are available are generally unstable and bug ridden.

^ +100
We know S6 is not going to have S810, why wouldnt they follow the same path with Note's too?
SM-N9005 is my last Samsung device, i am not going to drag myself to pain with Exynos.

New top score... 5130

Benchmark scores between flagship phones mean precisely jack s**t these days, they're little more than **** waving. Discernible features is what should be compared.
"Wow, my Android phone scored 200 more points than your Android phone! And please, let's ignore the fact it will make precisely zero difference in real world use!"

Ignorance is bliss!!
The whole point of these tests is to show that most of the other benchmarks don't show a true picture of real-life use.
Why else would Note 3 appear to perform better than Note4?
The PCMark webpage states the following...
PCMark for Android introduces a fresh approach to benchmarking smart phones and tablets. It measures the performance and battery life of the device as a complete unit rather than a set of isolated components. And its tests are based on common, everyday tasks instead of abstract algorithms.

It's in the interest of the benchmark app developers for users to believe their offerings aren't pointless.

I agree with you on this....... generally.
I however found this particular benchmark interesting for the following reasons....
1. It proves software is the biggest bottleneck in android phones, not hardware. ( Lollipop on Note3 >>beats>> kitkat onNote4 )
2. It proved that my Note 3 performs better in everyday use than my Note4 ( This I have always known but no benchmark showed it.)
