OMG! Quad Core Nvidia Tegra 3 Has Actually 5 Cores
We’ve been deceived ! All along we thought the new quad-core Nvidia Tegra 3 (codename Kal-El) would just have 4 cores…right… But Nvidia has just posted a blog entry talking about a mysterious fifth core. There is also the 12-core GPU, but we already knew about that. Here’s what Nvidia has to say about the fifth core: This extra core – which we call the “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 performance-tuned 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 […]
