Finally get to see Nvidia’s Tegra in real life on the Zune HD

As I mentioned in a previous blog the Zune HD will be the first mass-market product to be using the long-awaited Tegra platform from Nvidia. The Tegra is suppose to revolutionize video and graphics on portable devices similar to how graphics chips from 3dfx (for those of you who are old enough) revolutionized PC graphics so many years ago. Specifically, the Zune HD will be using the Tegra APX 2600 which is an eight core SoC (SoC stands for system-on-chip and it just means that all the different functional components that make up the system like a CPU, video codec, USB IO, memory, etc. are all integrated into a single chip resulting in significant size reduction and power savings). The eight cores of the Tegra APX 2600 consist of 2 ARM11 CPU cores, HD video encoder, HD video decoder, Ultra-Low-Power GPU for 3D graphics, 2D unit, Imaging unit, and an audio unit. The ARM cores can run up to 600MHz but all 8 cores will be dynamically clocked to achieve maximum power savings.  According to Nvidia power consumption is less than 1Watt during 1080p video playback. It will be interesting to see if this translates to impressive battery-life numbers on the Zune HD.
