Before Parker arrives, NVIDIA will ship Logan, a Tegra chip with 32-bit ARM cores and a GPU based on the Kepler architecture. Logan is anticipated to enter production in early 2014 and will be compatible with both CUDA 5 and OpenGL 4.3.
Huang also revealed Kayla, a new circuit board that pairs Tegra 3 with "a brand-new, low-power GPU". This will basically be the first Tegra product with CUDA support, the GPU connects to Tegra via PCI Express and will support OpenGL, CUDA 5, and PhysX. NVIDIA showed off a working card running ray-tracing in real-time, but didn't reeval how it will offer Kayla as an actual product.
