So in 2011 we have Tegra 2, in 2012 we have Tegra 3 so my questions is what will come in 2013? Octo-core or an improved version of quad core cpus?

Well as octo core desktop CPUs havnt really caught on yet I would guess just better quad cores likely with more powerful GPUs
Tegra 3 is already very powerful, presuming the will increase ram and make them more battery efficient or even higher clock speed. 12 core tegra gpu is pretty amazing already and anything better must be godly

If u mean for mobile platform , Will we really need beyond Quad core, having seen how SGSIII is smoothly running with it, beyond that what more perfection ( yaa still more can be expected) and speed u will need to do ur work . As known Android use other cores on need basis , why u need to see ur 2-3 cores never used.. i think its just more curiosity n to have more advaced/latest will be the only reason to have such high cpu on ur mobile..
What I like to see is ups in RAM installed and lows in RAM usage by system...
Sounds like octo-mom..the debate.lives on.. battery vs performance...but to answer your question I think it would be hexa-core which is 6..let's wait and see what is to come...

I agree. Cores are at there peak right now. The amount of CPU power we have especially in the higher end phones is enough to acomplish many, many things. RAM is somewhat of an issue especially since multitasking is a huge part of android. I really thing a 2gb RAM should be a standard soon. Also, better gpu's won't hurt

If they decide to keep going on the core upgrade in the next two or so years, I see one of two possibilities happening:
1) Dual Processor phones utilizing either dual or quad cores.
or
2) Hexacore chips since on the desktop market there's already a few 6-core chips (though whether or not they would actually be practical in the phones architecture, no clue).
Generally speaking whatever they come out with next will either need a better battery material, or lower power processors.
I mean I'm pretty amazed by what my brother's HTC One X is capable of with the quad core, and here I am still sporting a single-core G2. But yes I would like to see more advancement in RAM usage, we got a nice bit of power, but how bout a standard 2GB ram for better multitasking?
I believe 2013 will be all about more efficient quad-cores.
May i ask what going from 1gb to 2gb will improve? Loading times?
hello everyone, could you tell me what is cuad core?
Quad core means that a processor has four processing units.
Because there are more, that means that a process, theoretically, gets executed 4 times faster.
Read more about it: http://simple.wikipedia.org/wiki/Multi-core_processor
Maybe i7 in mobile devices?
I'm sure it will stay at quad core cpu's, anything more is just overkill. They may introduce hyperthreading. It's going to boil down to efficiency.

I'd say the future lies in more efficient use of processors. Right now, Android is still far from optimized on multi-core processor-equipped devices. Project Butter is the start of a great movement by Google to optimize the operating system. Hopefully it spreads out to other OEMs and becomes the main focus for Android development.
Improving and optimizing current processors is the way hardware companies should go.
In my opinion, processor development is out running battery development. Optimized processors could reduce power consumption while preserving excellent speed and usability.

building processors on more efficient ARM architectures is going to be the way to go from what I see......throwing four less efficient cores at a problem is the caveman method to dealing with it.....looking at you Samsung Exynos Quad based on tweaked A9 cores.....
the A15 based Qualcomm S4 Krait is more efficient on a clock for clock core for core basis and once the software catches up and starts using the hardware in full capacity, less more efficient cores will be preferred
I dont see anything beyond quads simply because they havent even scratched the surface of what can be done with a modern dual core processor yet.......throwing more cores at it only makes excuses for poor code.....i can shoot **** faster than water with a big enough pump......but that doesn't mean that's the better solution
We don't need more cores! Having more than 2 cores will not make a difference so quad cores are a waste of space in the CPU die.
Hyperthreading, duh.
More ram. Got to have the hardware before the software can be made to use it.
With the convergence of x86 into the Android core and the streamlining of low-power Atom CPUs, the logical step would be to first optimize the current software base for multi-core processors before marketing takes over with their stupid x2 multiplying game...
Not long ago, a senior Intel exec went on record saying that today, a single core CPU Android smartphone is perhaps better overall performing (battery life, user experience, etc) than any dual/quad-core CPU. Mind you, these guys seldom if ever stick out their neck with such bold statements, especially when not pleasing to the ear...
For those interested, you can follow this one (of many) articles on the subject: http://www.zdnet.com/blog/hardware/intel-android-not-ready-for-multi-core-cpus/20746
Android needs to mature, and I think it actually is. With 4.1 we see the focus drastically shifted to optimization, UX and performance with *existing/limited* resources. This will translate to devices beating all else in battery life, performance and graphics but since it was neglected in the first several iterations, it is likely we see 4.0 followed by 4.1 then maybe 4.2 before we hear/see the 5.0 which will showcase maturity and evolution of the experience.

Anandtech have now published the perfromance preview of the Nexus 10, lets the comparison begin!
http://www.anandtech.com/show/6425/google-nexus-4-and-nexus-10-review
Well, the first full result has appeared on GLBenchmark for the iPad4, so I have created a comparison with the Samsung Arndale board, which uses exactly the same SoC as the Nexus 10, so will be very close in performance to Google's newest tablet. GLBenchmark, as its name suggests test Open GL graphics perrformance, which is important criteria for gaming.
Which device wins, click the link to find out.
http://www.glbenchmark.com/compare....ly=1&D1=Apple iPad 4&D2=Samsung Arndale Board
If you're really impatient, the iPad 4 maintains it lead in tablet graphics, the Nexus 10 may performance slightly better in final spec, but the underlying low-level performance will not change much.
I've also made a comparison between the iPad 3 & 4.
Interestingly the in-game tests GLBenchmark 2.5 Egypt HD C24Z16 - Offscreen (1080p) :, which is run independent of native screen resolution show the following
iPad 4: 48.6 FPS
iPad 3: 25.9 FPS
5250 : 33.7 FPS
So the iPad is twice as fast as its older brother, the Exynos will probably score nearer 40 FPS in final spec, with new drivers and running 4.2, the board runs ICS, however Jelly Bean did not really boost GL performance over ICS. What is interesting is that iPad 4, whose GPU is supposed to clocked at 500 MHz vs 250 MHz in the iPad 3 does not perform twice as fast in low-level test.
Fill Rate, triangle throughtput, vertex output etc is not double the power of the iPad 3, so although the faster A6 cpu helps, I reckon a lot of the improvement in the Egypt HD test is caused by improved drivers for the SGX 543 MP4 in the Pad 4. The Galaxy S2 received a big jump in GL performance when it got updated Mali drivers, so I imagine we should see good improvements for the T604, which is still a new product and not as mature as the SGX 543.
http://www.glbenchmark.com/compare....tified_only=1&D1=Apple iPad 4&D2=Apple iPad 3
I'd imagine the new new iPad would take the lead in benchmarks for now as it'll take Sammy and Google some time to optimize the beast, in the end however actual app and user interface performance is what matters, and reports are overwhelmingly positive on the Nexus 10.
So Mali 604T didn't match 5 times better than Mali 400, or maybe Samsung underclocked it.
Still very good but not the best.
________________
Edit: I forgot that Exynos 4210 with Mali400MP4 GPU had very bad GLbenchmark initially (even worse than PowerVR SGX540), but after updating firmware it's way better than other SoCs on Android handsets.

Not sure about this, but don't benchmark tools need to be upgraded for new architectures to? A15 is quite a big step, SW updates may be necessary for proper bench.
Damn..now I have to get an iPad.
I believe we have to take the Arndale board numbers with pinch of salt. It's a dev board, and I doubt it has optimized drivers for the SoC like it's expected for N10. Samsung has this habit of optimizing the drivers with further updates.
SGS2 makes for a good case study. When it was launched in MWC2011, it's numbers were really pathetic. It was even worse than Tegra2.
Anand ran benchmark on the pre-release version of SGS2 on MWC2011, check this:
http://www.anandtech.com/show/4177/samsungs-galaxy-s-ii-preliminary-performance-mali400-benchmarked
It was showing less than Tegra2 numbers! It was that bad initially.
Then look when Anand finally reviewed the device after few months:
http://www.anandtech.com/show/4686/samsung-galaxy-s-2-international-review-the-best-redefined/17
Egypt (native resolution) numbers went up by 3.6x and Pro also got 20% higher. Now they could have been higher if not limited by vsync. GLbenchmark moved from 2.0 to 2.1 during that phase, but I am sure this would not make such a big difference in numbers.
If you again check the numbers now for SGS2, it's again another 50% improvement in performance from the time Anand did his review.
Check this SGS2 numbers now:
http://www.anandtech.com/show/5811/samsung-galaxy-s-iii-preview
http://www.anandtech.com/show/6022/samsung-galaxy-s-iii-review-att-and-tmobile-usa-variants/4
This is just to show that how driver optimization can have a big affect on the performance. My point is that we have to wait for proper testing on final release of N10 device.
Also, check the fill rate properly in the Arndale board test. It's much less than what is expected. ARM says that Mali-T604 clocked at 500MHz should get a fill rate of 2 GPixels/s. It's actually showing just about 60% of what it should be delivering.
http://blogs.arm.com/multimedia/353-of-philosophy-and-when-is-a-pixel-not-a-pixel/
Samsung has clocked the GPU @ 533MHz. So, it shouldn't be getting so less.
According to Samsung, it more like 2.1 GPixels/s: http://semiaccurate.com/assets/uploads/2012/03/Samsung_Exynos_5_Mali.jpg
Fill rate is a low-level test, and there shouldn't be such a big difference from the quoted value. Let's wait and see how the final device shapes up.

In areas where the Mali 400 lacked performance, like fragment and vertex lit triangle output T604 is comfortably 5 x the performance, whereas in these low-level tests iPad is not a concrete 2x the power of iPad 3, but achieves twice the FPS in Egypt HD than its older brother. I suspect drivers are a big factor here, and Exynos 5250 will get better as they drivers mature.

I agree with most of what you have said. On the GPixel figure this is like ATI GPU teraflops figures always being much higher than Nvidia, in theory with code written to hit the device perfectly you might see that those high figures, but in reality the Nvidia cards with lower on paper numbers equaled or beat ATI in actual game FPS. It all depends on whether the underlying architecture is as efficient in real-world tests, vs maximum technical numbers that can't be replicated in actual game environments.
I think the current resolution of the iPad / Nexus 10 is actually crazy, and will would see prettier games with lower resolutions, the amount of resources needed to drive those high MP displays, means lots of compromises will be made in terms of effects / polygon complexity etc to ensure decent FPS, especially when you think that to drive Battlefield 3 at 2560 x 1600 with AA and high textures, requires a PC that burn 400+ watts of power, not a 10 watt SoC.
Overall when we consider that Nexus 10 has twice the RAM for game developers to use and faster CPU cores, games should look equally as nice as both, the biggest effect will be the level of support game developers provide for each device, the iPad will probably be stronger i that regard. Nvidia was able to coax prettier games out of Tegra 3 through developer support, hopefully Google won't forget the importance of this.
What's the point of speculation? Just wait for the device to be released and run all the test you want to get confirmation on performance. Doesn't hurt to wait

Both A9 & A15 use the same instruction set architecture (ISA) so no they won't. Benchmarks may need to be modified, if the new SoC are too powerful and max out the old benches, but for GL Benchmark, that has not happened yet and there are already new updates in the pipeline.
I can't wait to see this Exynos 5250 in a 2.0ghz quad-core variant in the semi near future... Ohhhh the possibilities. Samsung has one hell of a piece of silicon on their hand.

True.. Chrome on mobile is still not upto desktop level yet. I believe it's v18 or something, right? The stock browser would have much better result in SunSpider/Browsermark. The N4 numbers looks even worse. Somewhere the optimizations isn't working.
The GLbenchmark tests are weird. Optimus G posts much better result than N4 when both are same hardware. It infact scores lower than Adreno 225 in some cases. This is totally whacked.
For N10, I am still wondering about fill rate. Need to check what guys say about this.
Is it running some debugging code in the devices at this time?

Actually not. A8 and A9 are the same ISA (Armv7), while A5 A7 and A15 are in another group (Armv7a)
Once we get rid of the underclock no tablet will be able to match. I'm sure the Mali t604 at 750 MHz would destroy everything.

I have to disagree, this is from ARM's info site.
The ARM Cortex-A15 MPCore processor has an out-of-order superscalar pipeline with a tightly-coupled low-latency level-2 cache that can be up to 4MB in size. The Cortex-A15 processor implements the ARMv7-A architecture.
The ARM Cortex-A9 processor is a very high-performance, low-power, ARM macrocell with an L1 cache subsystem that provides full virtual memory capabilities. The Cortex-A9 processor implements the ARMv7-A architecture and runs 32-bit ARM instructions, 16-bit and 32-bit Thumb instructions, and 8-bit Java bytecodes in Jazelle state.

I know that the ARM architecture is based on low-power mobile processing, but with upcoming release of the new Hardkernel ODROID development boards, at at a price tag of $89 for the ODROID-U2 and a Exynos 4412 Prime CPU, and supporting Ubuntu, I'm almost tempted to try it out as a desktop replacement.
But I'm wondering, how fast would it really be? Compared to Intel? Or is it impossible to say?

From what I've read around the Odroid forums, the performance of the Prime is supposed to be on par with first gen i3 processors, which is pretty descent for a mobile processor. They are also working on an overclock app that will allow the cpu to scale to 2Ghz per core. I plan on getting the odroid-u2 and I already have the odroid-x:laugh:

The S4 is halfway between the Cortex A9 cores and the new Cortex A15 core that we have. So it is decent enough of a CPU. I am not sure how good of a GPU that is. None of my devices the past couple years have had Adreno GPU's At least it wont have to work as hard with the lower resolution

From everything I've seen and experienced the exynos 5 is the better of the two. The a15 is a more powerful core than the krait core, that with the higher clock speeds and the better GPU makes for a better chip. Personally I have never had my n10 lag at all. Maybe you just got a dud?

But the Exynos 5 has to run that massive screen res. Also, the reason I think that Qualcomm modified the core was because of the power consumption. Stock A-15 core consumes quite a lot of power.

The Snapdragon S4 does not use an A15 core or any derivative of an A15. Qualcomm has ALWAYS completely designed their cores custom and has almost nothing to do with the current major core from ARM's reference design. Additionally, the S4 was designed and released before the A15 MP-Core was even finished with its design phase.
The Krait core uses a similar (but not the same) triple wide decode stage like the A15 core, but it uses a completely different 11 stage execution pipeline compared to the A15's 15 stage pipeline. The higher stages of the pipeline allow the A15 design to break things down smaller and achieve higher frequency, but if there were to be a failure in computing then the A15 must wait a longer time before it can start over where the Krait core doesnt have to wait as long, but also isnt as efficient in " normal" circumstances. Honestly the integer performance between the two cores is pretty close, but I think I remember seeing that the A15 has a lot stronger floating point performance. So I guess it really depends on your workload.
FYI, the Exynos 5, Tegra 4, and TI OMAP 5 processors are all based on the A15 core design. Qualcomm is the only major player who does not base their processors on the ARM design

Do you mean a drop in framerate during the animation when closing Maps? I notice a minor framerate drop which lasts as long as the animation does, but if that is it, I'm kinda wondering why you bought an android device in first place... I have not noticed this before and I cannot imagine anyone would using the device for its intended purposes. If you take any android device, you will find a fps drop at some point... Maybe return it and take an iPad? iPads do not have the issue, on the other hand there's a lot that iPads do not have ^^

THANK YOU!! my god I've had to explain this so many times! Qualcomm licenses ONLY the armv7 instructions and not arms designs. They design their own chips from the ground up and GPU, so please people stop saying Qualcomm is a cortex series processor because it isn't. Samsung and the rest license arms design and modify it, in Samsungs case they tend to increase the IPC slightly and give it more memory bandwidth.
Also to answer the question, exynos 5 will do better at higher resolutions and they will be very close in lower resolutions. S4 will be better in multi thread workloads more then likely and exynos will have better float performance. Exynos is better for games once the thermal throttling is fixed.

The 50 percent extra memory bandwith doesn't matter so much considered that the Exynos has to move almost twice the amount of pixels.

Memory bandwidth makes a pretty big difference when it comes too resolutions. I.E 8600gt ddr2 vs ddr3. Wider memory bus and faster memory makes a big difference in higher res performance of any GPU
Also will help with GPU compute performance for future apps utilizing the Mali t604s compute abilities

But lets say that Exynos uses the whole 12.8 gb/s bandwith. That means that to move twice as less pixels you would need 6.4 gb/s so memory bandwidth isn't an issue.

But that bandwidth is shared, unlike on dedicated GPU where it isn't. The total system bandwidth (not including buses for modem or w.e others are there) on the exynos chip being higher is gonna give it the edge in any situation considering the closeness in performance between the two. It also can't be denied that the Mali t604 has a edge in horse power over adreno 320 because even at the n10s resolution it comes within a couple fps of adreno at 1080p resolution. Not saying it's a big difference, but the exynos is the more powerful all around chip and that's just in is dual core form.
Edit: Also its a known fact that Adreno has crap fill rate compared too Mali or Power VR, Adrenos Strength is Geometry performace so it takes more of a hit the higher the resolution than Either the Mali t604 or the SGX 554MP4 which both have higher Fillrate and the SoC we have to compare both have higher bandwidth to facilitate that so we dont get bottle necked.

Finally a lot of exerts here about GPU
, I know it is not related to topic but me and my girlfriend have Galaxy Note 2 and S3. As you all know they are the last ones to use the elder Mali-400 GPU. I love playing games and I am getting my girlfriend used to them too. So I was wondering how is our Mali400 GPU holding up against the new coming 1080p Adreno 320 devices? It is clear the future is 1080p. I am either planning to switch our devices with a couple of Nexus 4s or Xperia Zs. Because I fear our devices are about to be outdated with the next game right around the corner. So far they are doing just fine with Modern Combat 4 and the all other graphic intensive games by playing over 28-30 FPS. But according to the GLBenchmark 2.5Egypt they are useless against new Adreno 320. However I have read that most of the games were designed for high fill rate power and Mali 400 is able to beat Adreno 320. But on the triangle tests, it just bottlenecks.
So what is your opinion about it? I will our devices do another year and half for the new games? Or should I make the trade? Or should I just buy a Nexus 10 with 2 users assigned and continue games on it? I
Thank you for reading.

They will hold on, my SGS2 runs all of the current games at the highest settings ( I haven't tried GTA though) without any issues, the Adreno 320 is far better than the Mali 400 MP4 though
Ya, Im pretty sure they will still play games a year from now. Until the market is completely saturated with devices like the Nexus 10 in power we wont really see large jumps in system requirements. That will probably only happen a year or two from now once all the new phones and tablets are made with A15 processors (or Qualcomm equivalent) and beefy GPUs.

The S2(Mali400) plays GTA3 without a hiccup.
The exynos dual is very power hungry compared to the s4pro but it is also the most powerful arm processor out today. Nothing else yet released (I said RELEASED) is as powerful or can match its bandwidth. Having said that I'm sure a normal resolution 1080p screen in this form factor with the s4pro would be a nice fast tablet. Right now the exynos dual is pretty much the only thing outside apple that can push the resolution that the n10 has. I think if they had put another gig of ddr3 in this thing there wouldn't be so much stuttering in certain instances. Besides the thermal cutoff the n10 is starved for memory as it has to share normal duties and its ram with the graphical load of pushing all the pixels of this monster resolution. You are lucky to have 300mb of ram available at idle on the n10 vs over a gig available with the s4pro on the 720p screen of the nexus 4

I wanted to know if there is performance difference between Windows 11 host and WSA client, so I have installed and run Geekbench 5 on both systems.
The benchmark results:
Windows 11
Single Core Score: 848
Multi Core Score: 2297
Details:
LENOVO 81LY - Geekbench
Benchmark results for a LENOVO 81LY with an AMD Ryzen 5 3500U processor.

WSA ( Android 11 )
Single Core Score: 677
Multi Core Score: 1487
Details:
Google Pixel 5 - Geekbench
Benchmark results for a Google Pixel 5 with an AMD Ryzen 5 3500U processor.
browser.geekbench.com
Resume:
Although the same hardware ( SoC ) is used when using the WSA a drastic performance loss can be observed: ~25% when running single-core CPU operations, ~35% when running multi-core CPU operations.
Info:
As of version three of GeekBench, the scores have been split into single and multi core categories. The Single Thread CPU benchmark, like all processor benchmarks attempts to estimate how quickly a processor is able to perform a wide variety of calculations. The test issues as series of complex instructions to the processor and times how long the processor takes to complete the tasks. The faster the processor is able to complete the tasks, the higher the benchmark score. The GeekBench Single Thread CPU test only runs one stream of instructions rather than multiple parallel streams per core. The majority of consumer applications (MS World, Internet Explorer, Google Chrome and most games), although multi threaded, rarely utilize more than one thread at a time, so this test, like any single threaded benchmark, can be seen as a reasonable real world test for typical consumer workloads.
Not useful for gaming!
Would've been interesting to add bluestacks to the mix too!

Correct: Even PUBG Mobile Lite crashes when it is loading.
