ARM-based Microsoft Surface tablet will have a Tegra processor, NVIDIA confirms
the Windows RT Microsoft Surface tablet will sport a Tegra processor. Exactly which processor will be used is still unclear, but the quad-core Tegra 3 is the first that comes to mind. One possibility is that the chip will be implemented using the NVIDIA KAI platform, which promises fluid performance at a competitive price point. Having a Tegra 3+ setup in the ARM-based Microsoft Surface tablet does not seem impossible either, although we are not quite sure whether this platform would be a good match for the device.However, NVIDIA was quick to acknowledge that
At the end of the day, the NVIDIA Tegra 3 is a pretty capable piece of silicon and we hope it will handle Windows RT without breaking a sweat. If priced right, the ARM Microsoft Surface tablet could prove a worthy alternative to top-of-the-line Android slates.
