The highly anticipated quad-core NVIDIA Tegra CPU actually has a 5th Core reveals NVIDIA.
The next NVIDIA Tegra CPU is seen to take Android Tablets to the next level and ahead of the iPad 2 in terms of raw processing performance. The Quad-Core NVIDIA Tegra has the code name Kal-El. NVIDIA's boss said recently that the first Kal-El Tablets will still arrive this year. It looks like NVIDIA is ramping up the marketing around Kal-El. A new blog post on the NVIDIA site reveals a secret about Kal-El. There is actually a 5th Core inside. This extra core, also called companion core, runs at a lower frequency and operates at exceptionally low power.

During less power-hungry tasks like web reading, music playback and video playback, Kal-El completely powers down its four high performance cores and instead uses its fifth companion core. For higher performance tasks, Kal-El disables its companion core and turns on its four performance cores, one at a time, as the work load increases.
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.
NVIDIA also highlights in the post that Kal-El has a new 12-core GPU that offer 3 times more graphics performance compared to the Tegra 2 Chip found in current Android Tablets.

NVIDIA has put itself in the central role with Kal-El to make the next generation of Android tablets more competitive with the Apple iPad. Now Google needs to do their part and make the next Android Update better than iOS 5.
