Kal El has same or better battery

Written by Fuad Abazovic


As Tegra 2
Despite the fact that we are still talking about the same 40nm manufacturing process, our industry sources are telling us that Kal El might end up with the same or better battery life than Tegra 2.

For a few that might not know this by now, Kal El is the 40nm quad core Tegra 2 successor that targets this fall's top tablets. Kal-El has very advanced power management which might help it to save a lot of battery life and the end result should be same or similar battery life for these new quad core processors.

With the same battery the next generation Motorola Xoom with Kal El can end up with close to 10 hours battery life and with four cores and much better graphics, at least gaming experience should increase tremendously. Kal El specs promises 1.5GHz core clock, 12 graphics cores aka unified shaders that can support 3D, Video output 2560x1600 if anyone needs that, as well as Nvidia’s "five times faster than Tegra 2 " performance claim.

Kal El’s successor codenamed Wayne (not Rooney, the Batmen kind ed.) in 28 nm process should bring up to 10 times performance increase over Tegra 2, once it shows its face in 2012.

Same IDLE battery life, maybe.

But not same battery life when it's actually USING those 4 ARM cores and more shaders. (Nvidia's shaders are well reknowned for being power-hungry).

hmm, not sure if serious. Kal El (Tegra 3) should have the same power management as Tegra 2, except for the GPU — they are both ARM Cortex A9 MP-core CPUs.

Another neat thing to notice, if they actually verified that the successor to Kal El will be 28nm, they as good as confirmed that it will be their first cortex a15, and that it will make 2012 timeline, not ARM's more conservative 2013. Where'd you get that stat?

tegra 2 is 1Ghz, so let's not make too many comparisons with a 1.5Ghz clock speed and battery life for dual and quadcores.

also, as pointed out, the manufacturing process and the graphics core are different too, so comparisons are even more apples-to-oranges.
