Tegra 3: anti-aliasing and output in September

Tegra 3, aka Kal-El, is the next mobile chip from NVIDIA. The SoC (chip all-in-one) should land at the end of the summer (apparently the end of September) and will propose some new face Tegra 2. First, it will go from two cores to four type Cortex A9, which can be useful in some applications. Second, the SIM has been added to the cores, was one of the (few) flaws Tegra 2.

SIMD "ARM", NEON, makes it possible to overcome the lack of FPU chips and software like Flash Player is already optimized. Finally, the GPU should be from 8 to 12 "cores," although the concept is rather vague in the case of Tegra. And this increase in power will actually be used: NVIDIA should propose a solution to the anti-aliasing.

The idea is simple: instead of taking into account three Tegra Tegra chips and leave the two on the floor for lack of power, activate the anti-aliasing can give a visible advantage to the new chip without increasing the performance of games the old ones. The increase in power offered by Kal-R is expected to enable this feature without (too much) loss of performance.
