Today at GTC 2013, NVIDIA CEO Jen-Hsun Huang revealed the latest Tegra roadmap and provided a preview of where their mobile chip is headed. Project Logan (Tegra 5) will introduce NVIDIA’s Kepler GPU architecture with CUDA cores, and Project Parker (Tegra 6) will include NVIDIA’s custom Denver CPU core, their next generation Maxwell GPU, and feature FinFET process technology.
We have yet to see Tegra 4 appear in devices, but NVIDIA expects products like Shield to start shipping in Q2. Jen-Hsun said that samples of Logan would be available by the end of the year, and we should see it enter production in early 2014. We captured the entire announcement on video, so look for a clip later today when the conference internet decides to start working.
