NVIDIA tonight unveiled Kal-El, a chip it claims is the first quad-core mobile processor. Likely to be called the Tegra 3, its two extra processor cores plus a 12-core graphics engine help it get into greater-than-HD resolutions in mobile. The system on a chip with the Superman-inspired name can smoothly play 1440p (2560x1440) video and has enough power to drive a Retina Display-like 300DPI image on a 10-inch tablet.
