[Q] About hardware and benchmarks - General Questions and Answers

hi,
There's something that I don't understand about how the mobile CPUs work.
Why is the Galaxy SIII stronger than the HTC ONE X (in benchmarks), although they are both quad-core and ONE X's CPU frequency is even faster by 100MHz?
How can the iPhone 5 be faster than the GALAXY SIII in benchmarks, although it only has a dual core 1.2GHz?
Thanks.

because they use different cpus. Some cpus are better than others. This also explains why Xperia T and V (both dual core) outperformed gs3 (quad core).

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

Here is a comparison benchmark by someone from Reddit.
Benchmark S4 Krait Tegra 3
Quadrant 5016 4906
Linpack Single 103.11 48.54
Linpack Multi 212.96 150.54
Nenamark 2 59.7fps 47.6fps
Nenamark 1 59.9fps 59.5fps
Vellamo 2276 1617
SunSpider 1540.0ms 1772.5ms
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).

[Q] Samsung Galaxy S III

The news broke that the samsung galaxy s iii will be arriving to all major us carriers in June. here is the article on the verge.
The official announcement confirms that it will launch with Qualcomm Snapdragon S4 1.5 GHz dual core CPU and 2GB of internal RAM vs the Exynos 4212(5250 need to verify which version they used) 1.4 GHz Quad-core and 1 GB of internal RAM
Can someone that knows what they are talking about tell me if there's a significant difference between the two specs I presented and which one will be faster vs battery consumption?
I am a T-Mobile customer, and looks like the SGSIII is said to come with HSPA+ with 42Mbps+, while the international version will be HSPA+ with 21Mbps+, on paper it is double the speed, what is the difference, is there sufficient coverage? I looked at the map for T-Mobile Data and they only show the strength of signal and don't differentiate the two.
so far here's the only real answer i've gotten on this topic?? anyone agrees?? disagrees? why?

sorry if i'm posting in wrong section, I thought of posting it in the GSIII general forum, but only international versions available, I'll get biased answers, my guess is also the SII users at least recent ones won't be upgrading, and I know the HTC One users will just try to make it look like their phone is better. I need an unbiased opinion. lol

[Q] Android: Exynos 5250 (A15 dual core) vs Rk3188 (A9 quad core)

I was going to buy a tablet for uni, and as i have some experience with computers i decided to compare the tablets and buy which was best for me, however i realized I'm a complete greenhorn in terms of phone/tablet hardware.
I found that these two processor was the ones i had to pick from:
Samsung Exynos 5250 - A15 Dual core @ 2 Ghz
Has an excellent GPU T-604
Rockwell Rk3188 - A9 Quad core @ 1.8 GHz
Has an decent GPU Mali 400
I know that the Exynos has a MUCH better GPU and has the newer A15 architecture, clocked at higher speed but is a dual core.
But the Rockwell is a quad core but has a older A9 architure and has the worse GPU.
I tried to search for a comparison but came nil because I was comparing between different release date/architecture.
Could you guys people explain to this newbie the advantages and disadvantages of each processor, and which one i should pick?
Which Processor is better? why is it better? Better by how much?
Which processor would be better at Nds emulation? I know android nds emulator support multicore and GPU support
Rk3188 (quad core) vs exynos (better GPU, architechture)
Which one has the lower battery consumption?
Thank you for your time.
at first is it Rockchip RK3188 , not Rockwell .. 2nd, A15 is faster than A9 even A9 is in A9 quad core state, for better compatibility support for apps and games .. take exynos chip but the price is hinger than rockchip RK3188 tablet... battery comsumption are vary depnds actual MAH on the tablet + how the user usage on it's tablet + version ROM that perform
Tablet is not only about processor, build quality, screen, speakers - its a package.
As you did not mention exact models under comparison, it depends on what you look for and budget.
For price/quality top score, you can't go wrong with one of Cube u9GTV (quad) tablets :
Retina, aluminum body, IPS, HDMI, stereo speakers and 9+ hours of battery.
I have one myself, and I used the dual core (old model) for a year, so I know they last well and are robust.
One of issues to consider is that having ADB over USB to Cube tablets is sometimes a mess, so I'm using ADB over IP to debug things, which might be not the best solution for a developer.
Best luck with your choice!

[Q] Number of cores vs clock speed

Hi all,
I've always wondered which would be suitable for daily use a Quad Core 1.5 GHz Processor or a Dual Core 1.7 GHz
let's assume they're both Snapdragon 400 processors
Which would be better
Thanks all
In my experience the amount of cores doesn't really matter. Many apps only use one core. So... I believe the 1.7 GHz dual processor will be faster.
Do correct me if I'm wrong.

I think multiple cores would make more of a difference. Multitasking would be better, and performance-intensive apps would be configured to use multiple cores anyway. For a real case, my friend's Galaxy Grand underclocked to 1 Ghz (dual core) is still better than my E at 1.3 Ghz (single core).

Yeah, OK. Multitasking will definitely be better on a quad core device. It's all about personal use. Theoretically the quad core will win. But you're never sure, until you test yourself.

It depends on the number of cores that an app uses, if it only uses 2 cores, it's obvious that the dual-core with 1.7ghz will work better.
It's like amd vs intel. AMD put in their FX8XXX/FX9XXX 8 cores while Intel puts 4 cores on their i7, but intel's cores run a lot faster so the I7 gets better performance than the FX9XXX
But if the app uses all cores, the performance will be better with the quad-core.
I personally think Clock speed > number of cores.
I got a higher score on AnTuTu ( Xperia SP ) than my friend ( Xperia ZR )

Well, not exactly AMD vs Intel, because Intel's got hyper-threading in their x4 core CPUs, which means two threads per core. However, AMD uses only one thread per core, so an octa-core AMD should work equivalent to an Intel quad.
Note that I said should. Some processors are just better optimized - my laptop's quad core AMD, when overclocked to 2.3 Ghz, performs slightly better than a dual core i5 at 2.4 Ghz (which should have an equal number of cores threads (got confused myself, lol) and a similar clock speed).
In the end, benchmarks on an AOSP ROM are the only thing you can completely trust, in my not-so-humble opinion.
AMD, I use an Intel 3rd gen extreme with turbo boost to 3.4Ghz on my Alienware m17x r4
Hyper-threading is indeed a great technology by intel

[Q] HTC One X vs Nexus 4 vs Galaxy S3 vs Note 2 vs G Pro vs Xperia ZL in real world

I have only used dumb-phones until now and plan to get a smartphone.
I did a little surfing and found Adreno 320 is better than Mali 400 GPU and Qualcomm Snapdragons are better than Samsung Exynos, right?
But in real world they say Note 2 is considered better phone than Nexus 4. I don't understand this.
Different phones top in different benchmarks, and still some things like display quality are not considered in benchmarks i guess, right?
Now I haven't used any smartphone before, and the I would be using it for gaming or watching videos/movies only most of the time as I'm a student.
Which of these phones that I mentioned (all in 23-29,000 INR range) are better than others in reality?
Those who have used these phones or are techsavy might be able to guide me in making the right choice
Just found S3 in India has different specs than in US, Canada etc.
India: 1.4 Ghz Quad-core Exynos 4412,Mali-400,1GB
US: 1.5 Ghz Dual-core Snapdragon, Adreno 225,2GB
