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.

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.

Even thought im a a snapdragon fan,72 cores sound awesome ,Always had nvidia gpu on pc. Ironically isn't snapdragon is co-developed by amd?

love it!! are they using there own GPU like snapdragon's adreno? 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?

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

dont look at benchmarks the qraphics quality in tegra 3 is best thats why games are thd not malihd

I already know that I must buy devices that use this chip, simply because it's named after Batman (notice the "Wayne" on top).

Next year Exynos will still lead.. ;)

on 2014, nvidia will bring its PC video cards to smartphones. Watch that out mate. :))) jk

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?

14. Lawliet

Posts: 160; Member since: Jul 02, 2012

Because it takes time to design, and this chip weren't available then

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

Because an A15 chip can't serve you for 2 years, huh ?

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!

37. TylerGrunter

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.

how does the mali -t604 compare to the gpu of the tegra 4 that's my biggest concern?

72 core gpu is awesome...finally tegra got a dual channel memory bus...hope they clock it very high...to provide enough data to those hungry cores :)

This will eat up exynos and qualcomm immediately. :D

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.

38. TylerGrunter

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

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

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 ;)

Yep. Can't wait.

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.

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

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.
