Late last night at CES 2014, Nvidia surprised everyone by revealing that its in-house 64-bit ARM core, Project Denver, would arrive this year in the Tegra K1 (Tegra 5/Logan), rather than next year in Tegra 6 (Parker). The Tegra K1 will ship in two flavors, a quad-core Cortex-A15 and dual-core 64-bit Denver, both with the 192-core Kepler GPU. While the GPU is exciting, and we'll be discussing its ramifications in due course, it is Nvidia's 64-bit Denver core that we'll be looking at in this story.
