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:

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..)
Hello all!
Long time reader, first time poster! I had a quick question... regarding the new 1.5 dual-core processors in the new phones (SIII, RAZR HD, etc., or even the HTC Rezound) vs. the quad-core processors soon to release on the newer phones in the coming months. How much faster is the quad-core vs. the dual-core? Please don't respond with "twice as fast," I get that I was wondering if there would really be any noticeable difference in the speed capabilities of the phone, even when worked to it's limit.
For instance, 1 degree vs. 2 degrees temperature - it's "twice as hot," but you're not going to notice it at all. But 40 degress vs. 80 degrees - "it's twice as hot" has a whole new meaning!
I am wanting to get a new RAZR MAXX HD, but was debating holding off for the LG Nexus or another quad-core phone that's on the horizon... Thanks in advance for all your help!
In Europe SIII has a quadcore too
Gesendet von meinem GT-I9300 mit Tapatalk 2
Personally I don't think it's noticeable at all. Maybe when browsing web, rendering goes faster in multi-core optimised browsers. And of course some games would run better. But I can't imagine any other use, unless you want to run SuperPI in the terminal there. It'll probably run nearly twice faster.
Edit: From the other point. There will be more and more optimisations in Android for multi-core SoCs, so quad-core will for sure "last longer".
Rebellos, thanks for the help! Not to open a whole can of worms, but what do you mean "run SuperPI"? Is this an app that I should be familiarizing myself with? (Fairly new to the ROMs, rooting, bootloaders side of things)
When I got my captivate, I had the option of waiting a month to get the atrix which had a dual core processor. I choose to go for the sure-fire "I Know it'll have dev support" single core processor and don't regret it.
This time however, there are like 3 quad core devices coming out. One x+ has a tegra 3, the Note 2 has an exynos. The Optimus G has an S4.
While dev support is still important.. the S4 is an incredibly compelling factor for me personally.

SuperPi is nothing more than a benchmark you really don't need to concern yourself with.
Remember when you are talking about cores, it is not simply the number of cores that you need to take into consideration but also the architecture which those new cores are built on. The new A15 Krait chips are dual core, but will blow the door off a quad core CPU with an older architecture. MHZ and Cores are relative. If they put out a modern super phone with a dual core processor you can bet those are two beefy and very fast cores.
There is the valid point that Android is going to continue to specialize in multithread execution but 1 core does not necessarily translate into 1 thread. A hyper-threaded cpu core actually shows up as 2 physical cores to the computer it serves, so if you are running a dual core that is hyper-threaded the PC thinks there is a quad core on board. It also depends on what type of application you are running as to whether a very solid 1 thread computational approach would be superior to a multi-threaded approach.
In short there is not set answer. There are hypothetical road maps defining architecture but these days innovation is so common said road maps could made an abrupt 180 if circumstances change. When if is time to buy a phone, or any computational device, consider what it's primary task is. That could help you decide whehter a multi or single threaded approach could be more effective. Ultimately as mentioned earlier everything is going the way of the multi-core, multi-thread, meaning instead of having 1 processor/thread complete 1 job, muliple processor/threads complete several mini jobs to arrive at the same point. Usually a multi threaded approach is more effective if designed correctly. Then look at what is available, where is your bang for the buck. Ultimately the number of cores and frequency run at has little to do with processing prowess. It's about design, innovation and engineering. Sorry if this didn't help much. It was more designed to give you something to thing about as apposed to pat, here you are, here's your answer as I rarely believe there is 1 approach or 1 answer to a solution. That's what computing is and computers = phones = innovation.
For gaming it makes a difference. For everything else, not really. Comparing the HTC One X vs the One XL (Tegra 3 Quad vs Snapdragon S4 Dual, respectively), the One XL benchmarks as faster than the One X CPU-wise (calculations), but the One X is more powerful graphically because the GeForce GPU inside the Tegra 3 chipset is more powerful than the Adreno 225 inside the Snapdragon S4. I have the Galaxy S3 i9300 while my girlfriend has the AT&T Snapdragon S4 Dual (LTE + 2GB RAM) version. Mine is clearly faster when it comes to heavy gaming, noticeably. Hers jerks on certain games like Beach Buggy Blitz, even on middle-level resolution, while mine runs completely smoothly on the highest resolution.
The only real comparison would be Snapdragon S4 Dual vs Snapdragon S4 Quad, or Exynos Dual vs Exynos Quad. The Galaxy S2 was as smooth as the S3, from personal experience (Sprint, Exynos version vs GS3 International Exynos version). Gaming was also super fast. But the Exynos quad is definitely more powerful.
TL;DR: It depends heavily on the chipsets being compared.
I have a T-Mobile Galaxy S2 running AOKP JB. In my opinion AOKP JB is A LOT faster than CM10. My phone is really fast now. Dual-core is still good.

True, but that's a completely different architecture. Exynos 4412 (the one in the i9300) is based on Cortex A9, whereas the Exynos 5520 is Cortex A15. It's like saying quad-core Pentium 3 vs dual-core Pentium 4. The Pentium 4 is a more advanced architecture, so it would win. It's like comparing apples to oranges.
Yes the 4412 is just double Dualcore

For heavy games it makes difference.
In my opinion, a A15 based dual core may be a better as an overall proposition compared to a quad core A9. The A15 should have approximately 20%-40%+ better single threaded performance. Most of the time you are working in a single threaded mode.
In fact you only need quad core when using a very high multi-threaded load. Not very common on a phone.
If however the choice is between a dual core A15 vs a quad core A15, the choice becomes very straightforward. Get the quad-core in that case.
Dual Core A15 vs Quad Core A9 (of the same type of chipset, like Exynos 4412 Quad in the S3 vs Exynos 5520 in the Nexus 10/Samsung Chromebook), Dual wins. It's more efficient and just overall more powerful. The first A15 chipset are the Snapdragon S4 Pro (Quad only) and the Exynos 5250. It's speculated though that the Galaxy S4 will have an Exynos 5 Quad.

Actually its Exynos 5250 not 5520 and s4 pro is not based on A15 architecture its quite similar but A15(dual core) gives better performance than s4 pro(quad core) in single threaded operations ,but in multi threaded operations s4 pro is better,but with same number of cores on both ,A15(quad core) would be better than s4 pro(quad core) in both multi threaded and single threaded operations.

Hello guys,
I'm kinda confused here.
I'm asking about a CPU I seen some phones and tablets claim that they have it as a Quad Core processor but somehow in other places like in Antutu and other benchmark programs it'll say something else.
now in the Chinese phone Market you'll see a new line of Quad Core Devices, tablets or phones.
they say they have: Samsung Exynos 4412 CPU and as far as I know this is a Quad Core Processor.
but when u launch Antutu for example on some of these new Chinese Devices you'll see it says:
Exynos 4x12
and will show something like this:
CPU Hardware: SMDK4x12
CPU model: Dual-Core ARMv7 Processor (VFPv3, NEON)
Click to expand...
Click to collapse
and actually when I read: Exynos 4x12 so the "X" doesn't clear it for me is it: 4212 the dual core one or the 4412 the Quad core one.. u see what I mean?
this is really confusing.
try for yourself searching for Galaxy s3 Clones or knockoff - Galaxy Note 2 Clones or knockoff and u'll see similar things to what I'm asking about.
also the GPU shows in some of these phones claiming to have Quad Core Exynos 4412 that it's: powervr sgx531, while the Samsung Exynos Quad core will have GPU: Mali-T604
lol the whole thing is messed up there..
hope that someone would come and clear it out so we dont get scammed when buying these devices.
thanks
Most Galaxy S2 or S3 clones and knock-offs use an MTK chipset such as the 6575 or the 6577. These would normally be paired with a previous-gen GPU such as the PowerVR SGX 530 or 531.
It is quite easy to modify Android to display a string about the CPU, anything you want really.
A true Exynos CPU will ship with a Mali GPU. The 4x series shipped with the Mali-400, the Exynos 5 in the Chromebook and Nexus 10 ships with the Mali-604, as you stated.
In short, you won't find an Exynos device without a Mali GPU. If it lists anything else - you're probably being misled
thx juzz86 for your reply.
u know what is making this confusion in my opinion?
it's when u read the CPU saying this:
CPU Hardware: SMDK4x12

SMDK stands for: Samsung Mobile Developers Kit and the 4x12 most people will think it's the Quad Core Exynos 4412 cause in the advertisement of the device(s) the sellers claim it has Quad Core processor.
so I found out that: reading SMDK4x12 or even SMDK4412 doesn't mean that the processor itself is the Exynos 4412 Quad Core.
the funny thing is when I demand from some sellers to go online with me and to turn on the camera so I can see for myself whats going on, only then they get scared when they see me ask alot about the CPU and that I doubt it's the Quad Core.
I also have to confess that some of them (the sellers) honestly didn't know that they have a Dual Core Device and not a Quad Core.
so guys... watch out and pay extra attention to the new Claimed to be Samsung Exynos Quad Core 4412 Processor.
ask for proof and Guarantees, and good luck
thanks again juzz
Yes mate, always pays to ask a lot of questions before buying one of these. Unfortunately as you say, most sellers don't understand what they are selling, just that it is 'dual-SIM'.
There is a pretty good following behind at least two of the clones here in the 'General' and 'Android Hacking' forums. Doing a quick search should pull up some.root methods as well.
MTK are getting better, and now even have a quad-core CPU in the works. That'll be a compelling option for some knock-offs, for sure!
Happy buying mate!

I think I just got scammed. Bought one of ebay couple of days ago and realize its most likely a fake
Found these cheap android tablets. They seem like pretty good compared to their price. But different devices are confusing me. They are many almost same devices but with a little different hardware and still they are named the same. I'm about to buy an iRulu 10.1 tablet. I'm not sure if there are 2 or 3 different versions of it.
iRulu's site was laggy but these charts are the same what I found on their site:
http://www.ebay.com/itm/iRulu-10-1-...90625890613?pt=US_Tablets&hash=item5af31e1135
http://www.ebay.com/itm/iRulu-10-1-...t=LH_DefaultDomain_0&var=&hash=item7b74f03c58
The first one: CPU Processor: "Rockchip RK2928 Cortex-A9 1.5GHz; Mail-400 Quad Core"
And the second one: "CPU Processor: Allwinner A20 1.5GHz; Mail-400 Quad Core"
What's the difference? Which could be better?
This one doesn't tell about 1.5ghz: http://www.ebay.com/itm/iRulu-10-1-...50886874301?pt=US_Tablets&hash=item51b27cccbd
"Allwinner A20 ARM Cortex-A7 Dual-Core; ARM® Mali400MP2"
According to many other sources, clock speed of that allwinner A20 cortex-A7 is only 1ghz or 1.2ghz. What are those Allwinner A20 1.5ghz processors then?
Moreover, I have seen iRulu 10.1 tablets with resistive screens that are not good. I also found very large amount of 10.1 tablets with some kind of allwinner 1.5ghz processor and seemingly same body. MAny of them don't even tell name or brand. I will be most likely buying the first or second one, but first I'd like to know about the processor differences. Only thing I know about android processors are the clock speed and number of cores.
Just realized that Rockchip RK2928 Cortex-A9 1.5GHz is not dual-core. Also, with further investigation, I became even more convinced that the Allwinner A20 dual-core 1.5ghz doesn't exist. Many are still selling that. Not sure if it's 1ghz or 1.2ghz.
Again found new models:
http://www.ebay.com/itm/iRulu-10-1-...90630383490?pt=US_Tablets&hash=item5af3629f82
"Allwinner A10 1.5GHz Mali-400" (single-core, but is it better or worse than RockChip?)
http://www.ebay.com/itm/iRulu-10-1-...90691725632?pt=US_Tablets&hash=item5af70aa140
"iMAPx15 ARM Cortex A5 Dual core 1.2GHz" (this vs Allwinned A20 Cortex A7?)
1.5ghz single-core or 1.2ghz dual-core, which is better? 1ghz dual-core?
This is really confusing.
EDIT: http://www.slatedroid.com/topic/44034-atm7029-an-arm-cortex-a9-or-a5/page__st__40 + many other sources seem like telling Allwinner processors are not as good as advertised. http://en.wikipedia.org/wiki/Rockchip Wikipedia says that that RK2928 would be single-core 1 to 1.2ghz. Odd

Stick with name brand. I got an infotmic imapx15 noria 7" for Christmas. The most I was able to do was root it. I just found flashing software from the manufacturer for it after searching for 3 months. Trust me, the Mali-400 GPU isn't that great as far as I'm concerned. Mine is also a dual core 1.2GHz and is still quite slow compared to my Galaxy S3. Just my .002
