[Android General] Turbotab:
Who has been excited by the Tegra 4 rumours?, last night's Nvidia CES announcement was good, but what we really want are cold-hard BENCHMARKS.

I found an interesting mention of Tegra T114 SoC on a Linux Kernel site, which I've never heard of. I got really interested when it stated that the SoC is based on ARM A15 MP, it must be Tegra 4. I checked the background of the person who posted the kernel patch, he is a senior Nvidia Kernel engineer based in Finland.

"This patchset adds initial support for the NVIDIA's new Tegra 114

SoC (T114) based on the ARM Cortex-A15 MP. It has the minimal support

to allow the kernel to boot up into shell console. This can be used as

a basis for adding other device drivers for this SoC. Currently there

are 2 evaluation boards available, "Dalmore" and "Pluto"."

On the off chance I decided to search www.glbenchmark.com for the 2 board names, Dalmore (a tasty whisky!) and Pluto (Planet, Greek God and cartoon dog!) Pluto returned nothing, but Dalmore returned a device called 'Dalmore Dalmore' that was posted on 3rd January 2013. However the OP had already deleted them, but thanks to Google Cache I found the results:)

CONCLUSION

Anandtech has posted that Tegra 4 doesn't use unified shaders, so it's not based on Kepler. I reckon that if Nvidia had a brand new GPU they would have shouted about it at CES, the results I've found indicate that Tegra 4 is between 1 to 3 times faster than Tegra 3.

BUT, this is not 100% guaranteed to be a Tegra 4 system, but the evidence is strong that it is a T4 development board. If this is correct, we have to figure that it is running beta drivers, Nexus 10 is ~ 10% faster than the Arndale dev board with the same Exynos 5250 SoC. Even if Tegra 4 gets better drivers, it seems like the SGX 544 MP4 in the A6X is still the faster GPU, with Tegra 4 and Mali T604 being an almost equal 2nd. Nvidia has said that T4 is faster than A6X, but the devil is in the detail, in CPU benchmarks I can see that being true, but not for graphics.

UPDATE

- Just to add to the feeling that that this legit, the GLBenchmark - System section lists the "android.os.Build.USER" as buildbrain. Buildbrain according to a Nvidia job posting is "Buildbrain is a mission-critical, multi-tier distributed computing system that performs mobile builds and automated tests each day, enabling NVIDIA's high performance development teams across the globe to develop and deliver NVIDIA's mobile product line"
