After discussing how Nvidia changed its entire approach to GPU design to create the new GK104, Jen-Hsun writes: “Today is just the beginning of Kepler. Because of its super energy-efficient architecture, we will extend GPUs into datacenters, to super thin notebooks, to superphones.” (Nvidia calls Tegra-powered products “super”, as in super phones, super tablets, etc, presumably because it believes you’ll be more inclined to buy one if you associate it with a red-booted man in blue spandex.) This has touched off quite a bit of speculation concerning Nvidia’s Tegra 4, codenamed Wayne, including assertions that Nvidia’s next-gen SoC will use a Kepler-derived graphics core. That’s probably true, but the implications are considerably wider than a simple boost to the chip’s graphics performance."
