Submission + - The Stealthy Fifth Core (

ozmanjusri writes: "Nvidia's next-generation quad core Tegra processor, codenamed “Project Kal-El,” has fifth core that runs at a lower frequency and operates at exceptionally low power. Kal-El completely powers down its four performance-tuned cores for less power-hungry tasks like web reading, music playback and video playback. As computing needs increase, the CPU progressively turns on each of the high performance cores.

The Variable SMP architecture is also completely OS transparent, which means that operating systems and applications don’t need to be redesigned to take advantage of the fifth core"
