So I visited www.phonearena.com yesterday and saw the news about the HTC Pyramid.At first I thought wow,Qualcomm and HTC won't only get left behind but will have about the same technology and will run at higher frequencies.
But then I remembered something that troubled me.I remember reading somewhere that Qualcomm's dual-core CPUs will be based on the current-gen Cortex-A8 by ARM,while others,like Samsung's Orion,will be using the next-gen Cortex-A9 that is superior in both perfrormance and consumption,while being designed especially for dual-core CPUs,unlike the A8.
What's your take on this guys?
No one?

Strongly agree
i hope this isn't true. tegra 2 outperformed old cpu's with only one core running! that's because it's Cortex-A9. now, if it was Cortex-A8, i don't think there would be much of a difference.
In fact i think it is superior to the tegra 2 or Orion plat form despite being an cortex A8 architecture, but it is not a long term solution point proven as Qualcomm is developing it A9 counterpart the MSM 89xx
How it is superior? Well between A8 and A9 architecture to my knowledge there isn't much of a difference, the major one is enhanced soc and the capability to use DDR3 ram instead of being limited to ddr2
But how these two doesn't matter in the short term, well the first one is obvious because Qualcomm doesn't use just a Normal Cortex A8 architecture ( was used on the first gen of snapdragon) as the second generation MSM8255 used on the desire HD for exemple has an enhanced soc and cach point proven when compared to a lets say Omap 3 or hummingbird in every cpu benchmark i believe the MSM comes on top(correct me if i m wrong).
The second point which is about Ram, i don't believe we will be seeing DDR3 ram on smartphone anytime soon so at this it is a kinda useless advantage.
Now add to that if the rumors are correct that one cpu can be switched off if the charge is low then while the on tegra 2 which use a dual core architecture and not a dual cpu architecture.
Edit: this is true + Asynchronis clocking for each core!
Also in terms of graphics, the MSM8x60 comes with adreno 220 which is definitly faster than the adreno 205 almost as fast as the SGX540 and which is rumored to be faster than the GPU in tegra 2, the geforce, as for the Orion is believed to get the SGX543mp2 but Orion is not coming anytime soon, and probably will hit the market once tegra3 and MSM89XX is almost there (which comes with Adreno 300)
Hopefully this does help you, i know that not everything i mentioned is accurate, but i ll invite you to watch this

Synthetic benchmarks like that though don't gauge real life performance though.

I do agree with you, but they do give a scal for the performance especially when there are different types that relies on a different system to test the perfomance.
In real world you have to agree that MSM8255 is the fastest CPU out there atm just look at how the Desire HD is a screamer! or even the G2/Desire Z with the same CPU but clocked 800mhz does a pretty great job even compared to the latest omap3/hummingbird phones.
Definitely, the MSM8255 45nm matches the old MSM8250 65nm even when the stock clock in the Z/G2 is only 800 mhz, versus that extra 200 mhz. The gpu is lacking compared to others.

As lotis said the only GPU that is faster than the Adreno 205 is the SGX540 and by a very slight marging in 3D while the Adreno wins in terms of 2D. The thing with Adreno GPUs is that they are clocked with the CPU and i believe the comparaisons were done with a G2 vs SGS + lagfix and froyo , i believe the GPU on the Desire HD does have a higher clock than the one on the G2 and thus perform better but again is this a fact or just another rumor if someone could confirm this..
But for a fact we all know that a stock G2 on pure android does 1600-1800 Quadrant score and a pure desire HD does a 1900-2100 on Android + sense out of the box

i m looking forward to the pyramid hopefully HTC will show it on the MWC (but im afraid there is a chance that they won't because they've just released the desire HD counter part in the US aka thunderbolt and inspire 4G) or else i might be tempted by the Motorola Atrix
whats up with all the fear and worries ? quandrant for tegra2 is a mere 1911 . it will get its a** kicked by anthing qcom makes in 2011 .
that said , there is a low possibility quandrant only runs single core enabled on quadrant , but what makes u sure that other apps will run dual core then ?

Nothing!That's the thing!
At the moment there is no software that takes advantage of both cores.I think that Gingerbread also has problems.So we have yet to see the performance gains by dual-cores.

I didn't think it was possible for an A8 to be dual core
The dual core cortex a8 qualcomm is building is a heavily customized version. It has features from a9 built into the cpu.

My laptop already is for surfing the net only because I prefer the large keyboard(it's a 17 incher after all ).Everything else I do with my smartphone,which has a 25% share of my gaming time.I also have a ps3!
Now,quad-core CPUs will first be for tablets(August 2011) and then for smartphones(Fall 2011?Maybe).These will pack some things like 12-core GPUs etc.Tests have already shown that they beat many dual-core x86 CPUs.What's next?Dunno,but I surely wanna see!
The next computers is possible, but relatively weak computers per say. But can any of our phones run crysis or crysis 2? Are they even remotely capable of generating over 10fps of it? Even the MALI 400MP, Tegra 2, adreno 220 or power vr SGX543 can't manage that. I don't think we'll be seeing any SoC's with that sort of power until maybe two years?
Point being, phones will never hold the same amount of power a computer can output. So computers will stay. Who's to say computer SoC's haven't been improving? sandybridge, quantum processing, six cores core i9, 48 cores? No one cares for computer news anymore?
Anyways onto the topic, looking at the new gpu benchmarks posted of the dual core snapdragon, 1.5ghz. They're making the other cpu's look bad. So maybe the SoC isn't that bad after all. looks like it was a prototype also so the finished product could be even better. Source:

Can htc implement a samsung exynos processor in their phones?

The processor is seriously powerful take a look at the amazing power of the latest samsung processor

They would have to buy and license them out from Samsung, but HTC probably already has deals and discounts with Qualcomm seeing that their phones are based on Qualcomm SoC's.
In all technical terms, can they use Samsung SoCs? Yes.
Now in real world situations, will they use Samsung SoCs? Most likely no.
HTC is a long time Qualcomm partner. Don't be expecting an HTC phone with a samsung processor. The qualcomm/HTC trend isn't going anywhere soon.

, htc really needs to step their game up with processors, obviously qualcome is behind on that aspect, adreno 205 was very competitive to the samsung hummingbird processor having a better cpu, however the new dualcore adreno 220 (if I'm not mistaken) does not stand a chance against the new exynos processor where the gpu is amazing and so is the cpu, if you compare benchmark the exynos 1.2ghz dual core scores 3300+ stock out of the box yet the htc qualcome 1.2ghz dual core scores 2000+ out of the box stock. So when you think about it qualcome hasn't done much of improvement on their new processor the mytouch 4G is a single core and scores 2000+ too. Benchmarks may not be everything but they do give you an idea. Bottom line is htc needs better specs for the tough competition, I really dislike tremendously samsung phone designs and would never switch to their phones no matter what processor they use.

Hi
I've been testing and comparing some of the top candidates og android phones on the market now.
The competitors are: Samsung Galaxy SII, Lg Optimus 2x (CM7) and HTC Sensation
And I must say, I'm pretty disappointed with HTC Sensation so far. Don't know if I'm just unlucky, or if we should expect an update on this in the future, but the GPU is way behind in comparison to the two others.
www.antutu.com benchmark results:
4578 - Samsung Galaxy SII
4456 - LG Optimus 2x
3758 - HTC Sensation
Goint through the details, the most worrying is HTC Sensation scores low on 2d/3d graphics, about half of what LG Optimus 2x scores, which is the winner, with a total of 297 + 350 in graphics. Sensation scores about 300 in total.
Qaudrant benchmark goes like this:
3678 - Samsung Galaxy SII
3120 - LG optimus 2x
2170 - HTC Sensation
Basically Samsung wins because of scoring higher on both CPU and memory (1gb ram)
LG Optimus 2x got he best GPU and Database IO (data transfer rate)
HTC Sensation is just way behind
What is your results? Is it just me, or could we hope for an update?
I have heard rumors about HTC Sensation only running on half of the kernels ind the GPU, is this true?
I heard it scores so low because of the Sense 3.0 requiring so much to run.
Maybe HTC should start concerning themselves more with function rather than form. I think everyone hear would rather have a faster device with less eye candy. If you look at what Samsung had done since the Behold II they have progressively toned Touch Wiz down with each iteration. I just hope we get the boot loader unlocked quick.

Sensation has such low benchmarks because it has qHD screen and Sense 3.0. Take Sense 3.0 away and this thing'll fly!
As I said in my own Sense 3.0 thread, having Sense 3.0 and qHD screen beats having high benchmarks. Benchmarks don't mean ANYTHING unless they're running the same UI overlay. Put them on stock/CyanogenMod and the Sensation will be a lot lot faster!

I agree with this. Sense requires a lot of ram and so does the qHD screen. That's the only reason benchmarks are so low. Get some stock GB on here and you'll see the difference. It also explains why the chip is clocked at 1.2GHz. I wonder how much further it can be pushed, though.

I've heard the chip is underclocked to 1.2ghz to save battery...it apparently can go to 1.5ghz, at least.

If you don't like sense then why buy the Sensation? That's like buying car that's a stick and then complaining because it's not an automatic. Yes sense is on the phone, yes sense may cause lower benchmarks, yes it's heavily intergrated. If those things bother you then perhaps purchasing a sensation was a mistake...not trying to start an argument, but really it illogical to complain about something you knew going in was a core part of the phone. I don't like touchwiz...so I don't purchase devices with touchwiz on them...it wouldn't make sense for me to buy a phone with touchwiz knowing I don't like it and then complaining about it.
Some ignorant people just don't get the fact. HTC had been advertised about Sense 3.0 for Sensation and we all do know it is a core part of the phone. So don't get the phone if you are for benchmarks isn't it? this sound silly, doesn't it?
Ah! Of course... the screen res is higher, that should influence on the benchmark for sure. Moto Xoom scores low also, but that too, has a higher res.
Im just concerned if it is still scoring lower when on stock. Does anyone have a true benchmark of the Adreno220, which is within the Sensation?
The benchmarks I found on the internet, the Adreno220/M8660 beats the crap out of LG optimus 2x and SGSII.
Anyone know if there is a truth to the "half cores only support" yet?

When we get s-off, we'll have some true benchmarks for all devices. Optimus 2x, Galaxy S II, Sensation, and possibly Moto Atrix. Put them all on latest release of CyanogenMod7 and benchmark them using a range of apps.

Actually its mainly because HTC chose to use old technology and use 2 second gen snapdragon chips which use the arm 8 instruction set, instead of using a cpu based on the new arm 9 technology which is what every other new dual core cpu is set up with.

As other people have stated, this view is nonsense. Scorpion is a parallel development to A9. It has advantages and disadvantages in comparison.
lol if you want to try and call it nonsense... I'm really just trying to help educate you and explain, but you can continue to think that if you wish
Scorpion incorporates some ARM 9 features, its basically like ARM 8 and a half and that is being optimistic -_-'

Your post is wildly inaccurate... First of all there is no ARM 8 instruction set. All A8, A9, and Scorpion processors use the ARMv7 instruction set. Second, Scorpion is Qualcomm's own architecture, it is not based on the A8 design, they created their own design from scratch. It is not as simple as A9 > A8 for this reason. The Scorpion architecture implements features that are not available on A8 but are available on A9. The main difference between the Scorpion and the A9 is the number of pipeline stages. The Scorpion has 13 while the A9 has 8. This is positive and negative for both, as more pipeline stages improves throughput, but is more costly if an instruction has to be aborted and the pipeline flushed.
I have gotten a lot of responses telling me that the Scorpion is based off A8 and tweaked. This is not correct. If it were simply tweaked, it would not be able to have a clock over 1 GHz without overclocking, as that is the limitation of the A8 architecture. It also could not support dual cores, again a limitation of A8. The Scorpion also has partial support of out-of-order processing. This is impossible on an A8 processor, but is fully supported on an A9.
You are correct in saying that every other dual core is based off an A9 processor because the A9 is the only design you can license from ARM that can support dual cores. The only alternative is for a company to license the instruction set itself and design their own architecture (Qualcomm's approach). I should also point out that the A9 processors are synchronous, while the MSM8260 is asynchronous, allowing separate clock speeds and voltages to each core, which can greatly increase battery performance (especially on processes that only utilize 1 core).
I will agree that A9 is more advanced than Scorpion, but it is not by nearly as much as the "Scorpion is A8" argument would indicate. The MSM8260 can also support clock speed up to 1.5 GHz, so the Sensation can be overclocked without actually overclocking the processor.

Exactly! I don't understand the logic of people that purchase a device that they know has certain features and then complain about it. That's like buying a phone with a slide out keyboard and then complaining saying you don't like the fact that it has a slide out keyboard. My thing is, Sense is not a surprise. Everyone knew going in that it was there, and they know what it is and how it works. If certain people don't like that, then they probably shouldn't have bought the phone. Doesn't make sense to complain about getting exactly what you were paying for.

Hi,
i recently return my samsung (4th time) galaxy s2 becouse of various defects , i been looking at the sensation however i have a few questions , firstly for all its issues i like how fast and responsive the galaxay was however when i tryed the sensation i noticed its not as smooth as the galaxy or that much smoother then the desire hd.
One possible reason for this i noticed was that the sensation uses a asmp cpu , which seems a bit cheeky to me. I mean im buying a dual core phone so i would like both cores to work at the same time as opposed to one working then the second kicking in when the first is loaded. From what ive read ics should have better support for this setup , so i was curious does anyone think we will see that much of a difference bearing in mind the sensation is asmp.
I notice there`s a lot of talented devs from the desire development and hd which is encouraging so i was hoping to learn from various users how much of a performance increase there seeing in custom roms ie is the browser jerky like stock ??
Appreciate any / all feedback thank you
I'm interested in some more more info on this topic as well.....

Read up!
ok so aSMP doesn't really work in the method of core 0 gets loaded then core 1 kicks in, thats way off.
basically SMP cpus like Tegra and Samsung's both cores run at the same speed, so core 1 follows core 0. This doesn't mean that core 1 is actually processing anything. In most cases due to gingerbread the phone is still mainly running on one core unless the app supports multicore.
aSMP allows the cores to run completely independent. This is great for battery life. Core 0 can do things like play games and stuff at full speed while core 1 handles background data.
so playing angry birds while syncing photos on flickr:
core 0 could be running at full 1.5Ghz
core 1 could be running at 500Mhz just do handle the syncing
This is basically the idea. We will get better support with ICS for full and proper support for multiple cores and the kernels will only get better as devs learn.

Hi,
Thank you for you detailed reply ive been following the thread you posted which is what led me to posting question here , i obviously misunderstood what was being said. That being said im no expert but if i buy a dual core phone id rather have both cores committed to one task like pc ... this is one of the things thats making me hold back on sensation. Althougth its a great phone with great ui and fantastic potential with future updates and dev support to the touch at present the galaxy s2 just seems smoother with the way its doing thing.
As i say thou im not expert i can appreciate theres other factor to take into account such as kernal etc, im just going with hands on usage and trying to evaluate the future potential for both devices before making a decision to which i should choose

The sensation's CPU works in a much more power efficient way, while still offering the speed of any other dual core CPU. It allows different clock speeds for different cores so applications using only a single core will be able to clock it differently to those using the other in the background. Computers, especially laptops work in a similar way, as there is a need for power efficiency. Realistically the Galaxy SII runs smoother due to it running a much less resource hungry skin on top of android, but both the CPU of the sensation and the Galaxy SII are both of a similar calibre, so it is very difficult to say which is better.
again thanks for the reply , defintly understand how this asmp buisness works more now which has given me some stuff to think about

Neither architecture, SMP or aSMP, will commit both cores to one task unless the app is multithreaded and it currently needs the use of both cores. This is the same way that multicore pc's operate. That's why when quad core CPU's first came out people said that they didn't feel any faster than comparable dual core chips - most existing apps at that time were written for single or dual threaded use so the third and fourth cores largely sat unused. The pc doesn't just force the use of the extra cores just because they are there (regardless of how they scale, aSMP or SMP).

Also the new firmware has made it smoother due to extra optimisations. Web browser is not as good as the galaxy S 2 due that being GPU accelerated. Power wise the Sensation you will get somewhat more out of your battery life wise.

Realistically the Galaxy SII runs smoother due to it running a much less resource hungry skin on top of android, but both the CPU of the sensation and the Galaxy SII are both of a similar calibre, so it is very difficult to say which is better.

If you look at my thread and see the post:
MSM8x60:
Adreno 220 GPU
2x Cortex A8 Based Cores
512KB L2 Cache
45nm
upto 333Mhz LPDDR2
Exynos 4210:
Mali 400 GPU
2x Cortex A9 Based Cores
1MB L2 Cache
45nm
support for LPDDR2/DDR3
Tegra 2:
ULP Geforce GPU
2x Cortex A9 Based Cores
1MB L2 Cache
40nm
support for 600Mhz LPDDR2
So the biggest thing is is that the Exynos is based on a new core micro-arch then the Snapdragon 2, also it has the ability to support DDR3 memory. To go into more detail about ARM Cortex.
Items that A8 and A9 have in common:
Jazelle RCT for JIT Compilation
Neon SIMD Instruction Set (Optional)
Thumb2 Instruction set
VFPv3 Floating Point Unit (Optional)
Cortex A8:
Superscalar Dual-Issue Micro-Arch
2.0 DMIPS/Mhz
Cortex A9:
Out-Of-Order Superscalar Micro-Arch
2.5 DMIPS/Mhz
Jazelle DBX for Java Execution
Dual-Core Processing Built In
The SGSII has a new generation architecture as so does the Tegra
This thread is iteresting. I want to continue that.
my cpu0 and cpu1 arrive at 1,7 ghz. so cpu1 doesnt arrive up to 500 mhz
Yes I've used the search tool and the last post in the last Exynos 5250 thread was at december 2011 and I can't find any rules about reviving old threads so I don't want to fiddle with it since I might get an infraction or worse a ban and and the last Tegra 4 thread wasn't coherent enough for me.
I don't know all the details but I would like to start talking about the supposed new Exynos 5250 and Tegra 4 development so please bear with me, I need all of those who has reliable information to add in the discussion. I'd like to start things with how will it fare against this year's smartphones and tablets? specifically the Samsung Galaxy S3 (1.4 ghz Quad ARM Cortex-A9 + Exynos 4412 & 1.5 GHz dual-core Qualcomm Krait + Snapdragon S4 MSM8960) and HTC one X ( 1.5 GHz quad-core ARM Cortex-A9 + Nvidia Tegra 3 & 1.5 GHz dual-core Qualcomm Krait + Snapdragon S4 MSM8960) since they are currently the top Phones out there in the market performance wise.
Further into the topic will the new Exynos and Tegra make their predecessors completely obsolete once they come out? or is the performance leap going to be minimal at best? due to various factors perhaps you can't fully utilize their potential due to the limiting software apps out there? What I want you guys to elaborate for the community is how better will it be in terms of CPU and GPU benchmark performance. Please do share your Ideas and any reliable information about the said topic at hand.
P.S. I just got an SGS3 my very first smartphone and android, did I make a huge mistake by buying it or should have I gone for a cheaper Galaxy Nexus and waited for the new Exynos to come out?

what better than Nvidia Tegra 3
First off, let's talk processors:
Your phone, the SGS3 i9300 is packing the Quad-Core Exynos 4412, rather than the dual-core Snapdragon S4 (MSM8960) for North American versions of the SGS3. The international version of the HTC One X has the 1.5GHz Tegra 3 vs the North American version which has the S4 as well.
Performance wise, these processors are all pretty on-par. Benchmark scores are close, with the Tegra 3 gaining the upper hand graphics-wise with its 12-core GPU. The processor to look out out of these 3 would be the S4, considering it's the first processor to (kinda) take advantage of the A15 cortex.
...The reason I say kind of, is because there is some discussion on the S4 being a hybrid between the A9 cortex (Tegra 3, Exynos 4) and the beastly A15. Qualcomm is a rebel, and doesn't follow ARM's chip designs like the others do. But I digress...
A15 is going to be a HUGE improvement over A9. HUGE performance gains, higher resolution displays, USB 3.0,OpenGL ES 3.0 (depending on the GPU) and much much more. The dual-core Exynos 5250 is going to be based off the A15 cortex, and it's going to blow even the quad core A9's out of the water. Tegra 4 will almost definitely be based off A15 as well, and it's going to be a sight to see. As for the Snapragon S5, who knows? I'm sure Qualcomm has some cool stuff up it's sleeve.
To answer your question, yes the new Exynos and Tegra processors are going to make older generation processors obsolete, but that doesn't mean you made a bad choice. The SGS3 is a great phone, and as such has tons of developers making custom roms, kernals, and other fun hacks to keep you occupied for the months to come hack away!
hope that helped!
You didn't make a mistake as at present android is not able to push current quadcore devices to their limits and there is a scope for lot more improvement
So even though next gen processors will be lot more powerful, your phone will still be able to handle next android releases so Don't worry and enjoy your S3

Android already has full multi core support. The only thing holding back multi cores is the fact that many apps still don't make use of them.
Also, that other guy made some great points but forgot to mention S4 Pro, which we already know a good deal about and is very impressive. It sets the bar high for the next tegra and for exynos 5250.

They're not going to be "completely obsolete" (even GN and SG2, for example, are still good phones despite being "last year") but there is going to be a large performance increase to A15.
There's always a next big thing coming out, but generally it's not worth waiting for unless you're on the cusp. Even if the generation you shop is relatively old, the competitive market (unlike, say, that of a fruity company) helps to compensate you by providing discounts of the previous tech.
S3, in particular, is a darn good phone no matter how you look at it (except that it has hardware buttons, but I digress..)
