NVIDIA Tegra 4 will come with 72 GPU cores, leaked slide indicates
Several weeks ago, we ran a comparison between four quad-core mobile processors. Most of the time, the Tegra 3 by NVIDIA was the weakest performer, which actually shouldn't come as much of a surprise since it is made using the older 40nm manufacturing process, while the competition has long stepped into 28nm territory. The upcoming Tegra 4 chip, however, will put NVIDIA back on track as it will most likely rely on four Cortex-A15, 28nm processor cores, backed up by a fifth power-saving companion core to handle the more basic of tasks. But a big leap forward is expected to come in the graphics department as well.

According to this leaked presentation slide, supposedly detailing the structure of the NVIDIA Tegra 4 SoC, the company's next mobile chip will offer 72 graphics cores. All that silicon should deliver six time the raw performance currently offered by the Tegra 3, which has "only" 16 GPU cores at its disposal. The new chip will be capable of handling screens of size up to 2560 by 1600 pixels and will have no troubles recording or decoding 1440p video. In addition, the slide mentions the support of a high-speed imaging chip, USB 3.0, and dual-channel DDR3 memory.  

If earlier leaks are to be trusted, the NVIDIA Tegra 4 should launch during the first quarter of 2013, meaning that we are likely to hear more details about it during CES or MWC next year. And who knows, we might even be introduced to the first smartphones and tablets that will be powered by the new chip. How it will stand against the existing quad-core offerings, however, such as the Snapdragon S4 Pro or the Exynos series, remains to be seen.

Wow, 64 GPU in a chip
4 A15 cores and 1 A7 core?
28 nm technology.

this chip will blow competition out of water

Doesn't mention an A7. Speculation is fine but not when you declare it as truth.

Mali 400 has 4 cores, and tegra3's gpu has 12 cores but Mali 400 performs better......no. of cores matters but cores wit new and better architecture performs better

Tegra3 doesn't have unfied shaders so it does lose on efficiency...but those 12 core are good enough to trump Mali 400...If you see benchmark results...Tegra3 performance is really choked by it single channel memory interface. Now These issues are sorted...in Tegra4 to some extent (I'll still like to see 4 channel bus like in A5/A6).

Mali 400 doesn't have unified shaders either. Tegra 3 GPU is nowhere near Mali, just compare the Note 2 with any Tegra 3 running device.

"Core" is a confusing term used in comparison of such chips. Mali 400 MP4 is actually like having 4 GeForce T3 GPUs put together. Tegra 3 is a single GPU. Mali and PowerVR GPUs, can be compared to the GTX 690, while T3 GPU is just a single GTX 680.

Wrong. Gtx 690 has two physical GPU's. Kind of like having two xeons on the same board.

Wrong, CUDA Cores are more like stream processors and not actual physical cores. It has nothing to do with regular cores.

Cores are used to do math calculations (for graphics)

Analogy :
its like having a two way street with only two lanes vs one with 4+ lanes, when you have

100 cars can go faster on a 4 lane road than a 2 lane one

What do I think about that processor?

I think that's a better analogy for the bus width than the number of cores. Number of cores would be likened to the number of cars, each carrying information.

If you've got 72 cars (full of information) trying to deliver it down a single lane road (say, a 64-bit wide bus), they will be slower than on a dual lane (128-bit), which will still be slower than on a quad lane (256-bit).

More cores can calculate more math, but other factors like bus width and speed and GPU efficiency can bottleneck it such that another, fewer core GPU is more efficient.

Qualcomm never chose to implement A15 cores (krait is not entirely A15)...so current king APQ8064 will be dethroned in next few months...but Exynos 5 will have A15 cores...so It'll be Tegra vs Exynos next year.

The battle I want to see will not be from processor to processor since I know those will be amazing but to compare a T-604 in the 5250/5400 vs the Tegra 4 GPU. Mali has done very well inthe GPU department but if the GPu in the Tegra 4 is a s powerful as they say this may be interesting.

posted on 18 Dec 2012, 09:22 1

38. TylerGrunter (Posts: 905; Member since: 16 Feb 2012)


For the theoretical count the T-604 and the Tegra4 GPUs should be in the same range, it will depend on speed of the memory bus and the clocking.
But we'll have to wait for the benchmraks to have any final saying.

42. jove39 (Posts: 1278; Member since: 18 Oct 2011)


T604 is no match for 72 nvidia cores...believe me on this! I also doubt low memory bandwidth may restrict performance of nvidia gpu.

51. TylerGrunter (Posts: 905; Member since: 16 Feb 2012)


I´m talking here just with the theoretical numbers, so I won´t put my hand on the fire here. My expectations is that the GPU will be somewhere between the Mali-T604 and the PowerVR SGX 554MP4, but as I said to Pedro0x I´m making a bold assumption here: that the new cores are only able to do 1 MAD per cycle. If I´m wrong there my calculation is screwed, but if I´m right (and I´m probably right) it should be quite a good aprox. We´ll see it when it comes out anyway ;)

Not really, the Exynos 5 is currently using Mali-604 and 32nm as a technology.
If the next Exynos one is on 28nm and uses a Mali-624 instead it will be Exynos victory again.
The Tegra 4 has "only" 72 cores, that gives you a theoretical limit of 43.2 GFLOPs @300 MHz, that's well below the PowerVR SGX 554MP4 on the iPad 4 (76.8) and just in the range of the Mali-604.

posted on 18 Dec 2012, 09:54 1

40. Pedro0x (Posts: 271; Member since: 19 Oct 2012)


That is because SGX554MP4 has 128 MADs which means 4 MADs per 1 SIMD. If tegra 4 will use 2 MADs per 1 SIMD then it will 144 MADs and that equals 86,4 GFLOPS at 300MHz and as I know NVIDIA they will overclock it to at least 500MHz which equals 144 GFLOPS, holy f---.

41. TylerGrunter (Posts: 905; Member since: 16 Feb 2012)


You are right there, I'm assuming 1 MAD per cycle, but as that was the case in the previous GPU, I don't think it's a bad assumption. If the new Kepler cores can do 2 MADs per cycle then this GPU could be awesome. But I prefer not to put my hopes very high.

47. Pedro0x (Posts: 271; Member since: 19 Oct 2012)


Yes, of course, we can not have our hopes too high. But it would be awsome if NVIDIA would do it. But Apple will surely just add 2 more cores and overclock it.

I believe that is a fake, this new power vr is suppost to have around 213-230 GFLOPS so 3x more poweful. This should come out late 2013. And Xbox 360 graphics has 240 GFLOPS so this will finally have ´´console graphics´´.

wtffffff
so this means if I buy the latest of Google (nexus 10) it will be an old technology in 3-4 months
so why didn't they release the nexus 10 with this chip?

its not about time I am talking about cause I was waiting for so long for Google to release a 10 inch tablet and now that it did

even though I want the nexus 10 so much and I want to buy it
I now have second thoughts to to wait for the new tetra 4 tablet

my point I don't want to keep upgrading all the time I just want something that will serve me for at least 1-2 years without thinking of upgrading

I am just saying that maybe Google shouldn't have rushed with nexus 10 and maybe waited for the tetra 4

2 core Exynos5 is no slouch...its fast enough...just not fast as Tegra4...in another 4 months or earlier we'll see 4core Exynos...with T658 gpu...then it'll be able to compete with Tegra4!

posted on 18 Dec 2012, 09:20

37. TylerGrunter (Posts: 905; Member since: 16 Feb 2012)


I doubt the will use the Mali-T658, the 8 cores are too power hungry.
Anyway, the Mali-T604 should be already in the same range as the GPU in the Tegra4, and if Samsung uses the new Mali-T624 instead they'll easily surpass it.

so many cores but it still doesn't destroy the competition as it should. The 16 core GPU is actually inferior to the quad core Mali 400. It's just numbers from NVIDIA...not that good of a performance

and i think i disagree with the statement that Tegra 3 is the weakest on its competition...wasnt oneX runs on tegra 3 but why is it still on top on benchmark test?

This is good for all of us no matter how you look at it. Even if nvidia is not your cup of tea. This will only push Qualcomm and Samsung to up the anti in their respective chip sets. I just hope battery tech can be picked up to keep pace with these ever hungrier processors.
