HTC One X
Dual core MSM8960 working at 100% is faster than tegra 3 as a CPU (by a bit more than a bit).
Qualcomm's dual core is insanely fast!
As for the graphics of course Nvidia is better (the same, by a bit more than a bit).
They are almost on par despite the number of cores.
Yet have to test the battery life for both "One X .
Nvidia's is 40nm and Qualcomm's is 28. Even though, Tegra3 idles at lower power as it does whith light tasks. Draws more than the Snapdragon when working at full capacity.
This bases on synthetic benchmarks though.
I can't wait for phonescoop's review. Better if they test both devices.
