Nvidia unveils the Tegra K1 SoC with 192 CUDA cores

The new Tegra K1 has two important selling points. The first is that it uses a GPU with 192 CUDA cores based on Nvidia's Kepler GPU architecture, the same used in the desktop GeForce GT 600- and 700-series GPUs. Secondly, some versions of the chip will be the first to ship with Nvidia's custom "Denver" ARM CPU, a 64-bit architecture that supports the ARMv8 instruction set.

The CPU gets more complicated. There will be two different, pin-compatible versions of the Tegra K1 that are differentiated by their CPUs. One will use four ARM Cortex A15 cores (plus one power-saving "shadow" core) running at up to 2.3GHz. That's not much different from the CPU configuration used in the current Tegra 4. Only the higher-end version will use the new 64-bit Denver architecture, in a dual-core configuration running at up to 2.5GHz.
