Nvidia Tegra 4 Will Have 72-Core GPU, Ultra HD Support?
A supposed leaked slide reveals Ultra HD output support, 72 GPU cores and more goodies spicing up the Tegra 4 SoC.
A slide supposedly containing information about Nvidia's Batman-themed Tegra 4 "Wayne" SoC has surfaced, revealing that the chip will sport a 72-core GPU and support Ultra HD video. The slide made its first appearance on the China-based Chiphell forum thanks to a user called Xenomorph.
According to the specs, Nvidia's Tegra 4 may be a quad-core 28-nm chip using the 4-PLUS-1 architecture like the previous Tegra 3 SoC – the +1 is what the company calls the "patented battery-saver core". There's speculation that these cores will be based on ARM's latest Cortex-A15 design although the slide doesn't mention anything about the baseline design.
As previously stated, the processor cores will be partnered with 72 GPU (GeForce) cores that will support a display resolution up to 2560 x 1600 @ 120 Hz. The output rendering will thus be six times that of the current Tegra 3, and twenty times that of the older Tegra 2 chip. The Ultra HD aspect is likely related to the max video output through an HDMI connection.
The slide goes on to reveal that the Wayne SoC will support DDR3L, LPDDR2 and LPDDR3 dual channel memory, USB 3.0, and security features like HDCP, Secure Boot and DRM. ZDNet points out that Apple's current A6X SoC which powers the new iPad 4 is around 4 times faster than the Tegra 3, so this new Wayne chip should put the heat on Apple when it makes a likely appearance next month during CES 2013.

No, Nvidia, those aren't security features...
lets see how its 2nd gen quad core fares...

Cheers!
It seems my Galaxy S3 dual core can smoke my Nexus 7. And with that, I hope they start packing 2GB RAM into the new Tegra 4 devices.

so what did you expect them to put? this news is based on the rumor from chinese website chipdell. nvidia themselves still not officially release most things about tegra 4.
of course krait will be faster. they come much later than tegra 3
They will rely on the press to hype the **** out of it with words like "Powerhouse", "Beastly". and pay off developers to make exclusive stuff for it.
Some stuff I'd like to know:
- did they fix the abysmal memory bandwidth?
- Did they improve the GPU architecture or its the same T2/T3 gpu with more cores?
They marketed the hell out of the gpu cores number in Tegra 3, but its preformance was/is utter crap compared to the SGX, Mali, and Adreno competition.
This will be beat by stuff in sept, but again, those will be too late to get into a device most likely or on the cusp for xmas etc (note Qualcomm whining that nv just came first...yeah, that's the point to get design wins for a certain date). Since exynos5 in my dads nexus 10 does pretty well at 2560x1600 but just a tad weak in gpu this should be better especially since they actually get tegra games optimized and it looks like it should be 25-30% faster than exynos. I expected a 48core (4x current). It looks like they actually aimed at apple not current exynos/snapdragon pro which are underpowered for this res. Nexus 10 should have chose apples res and it would have been excellent. This should make a decent 10 at 2560x1600 finally. I hope google is tooling up for a nexus10 rev2.
IF this slide is true (big if, I really expected 48gpu, a simple quad of the gpu), this will rock for a while and make it into a ton of devices for xmas (from july products on probably in volume). I like the fact that they release like this, to make it into Aug->xmas devices (like the nexus7) with no chance of missing that boat. I think samsung upped the exynos6 date to try to get in more xmas stuff also. There are NOT enough of the nexus4/10 and they needed to land their chip a good 2 months earlier to get more production/designs for xmas, which it looks like they're doing this time. Good times ahead...Here comes the nextgen SOC war
If this is wrong and it's 48core though, it's just a exynos5 type and isn't enough for 2560x1600 (perhaps why they made it 72...they saw and recognized the issue with exynos5).
I went to ZDNet to see if it can match Tom's. It is literally the most Apple biased tech site I've ever been on, other than Cult of Mac. All the people hate the Apple articles there, just like the people hate the Apple articles here.
Now thats some apple bias lol

The Tegra 3 isn't the top dog, performance wise, in the SOC market. It's just the best value right now. A better performing chip is the Samsung Exynos, though it's exclusive to Samsung products unfortunately. Samsung still makes Apple's processors right now too.
