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

Read again it says 72 core gpu

it think its 72 CUDA cores something like a geforce graphics card

24. MeoCao unregistered

ur right, I'm too excited. lol

im really hoping they go for a wolfson DAC with the soc that realtek is no good

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

These must be CUDA cores, not like those in Intel Cpu's.

Just curious, what is the advantage of having many gpu core?

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

12. wendygarett unregistered

Got it :) So how do you think about this? I just wanna learn more thing so no offense lol

How do I think about the analogy? Or 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.

Nvidia please get rid of the PRISM technology, it only gaves a poor contrast to the screens.

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.

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.
