Quad Core and a GPU is a bit more accurate, but still an interesting system. I wonder when development boards will go on sale.

  Not according to Wikipedia : http://en.wikipedia.org/wiki/Nvidia_Tegra#Tegra_3_.28Kal-El.29_series http://en.wikipedia.org/wiki/Nvidia_Tegra#Tegra_3_.28Kal-El.... The Tegra 3 is functionally a quad-core processor, but includes a fifth "companion" core. All cores are Cortex-A9s, but the companion core is manufactured with a special low power silicon process. This means it uses less power at low clock rates, but more at higher rates; hence it is limited to 500 MHz. There is also special logic to allow running state to be quickly transferred between the companion core and one of the normal cores. The goal is for a mobile phone or tablet to be able to power down all the normal cores and run on only the companion core, using comparatively little power, during standby mode or when otherwise using little CPU. According to Nvidia, this includes playing music or even video content.

    You're right, I was mistaken! I also found some more detail from this more technical explanation: http://www.anandtech.com/show/5072/nvidias-tegra-3-launched-architecture-revealed http://www.anandtech.com/show/5072/nvidias-tegra-3-launched-...

    To me this is the interesting feature, not the "more power than before", which was to be expected. Ironically, none of it is presented in the article nor videos. I also find the "throw more power at it to get it smooth" argument quite appalling.
