Propellerads According to Huang, the Tegra X1 doubles the performance of its K1 predecessor within the same thermal envelope. It's unclear whether Huang was referring to the quad-core ARM Cortex-A15 version of the K1 or to the dual-core Denver variant, but either way, the X1 looks like a substantial upgrade over the current generation.

The Tegra X1 combines 256 shader processors with an eight-core CPU "in a 4+4 configuration." The 64-bit CPU uses a big.LITTLE combination of four ARM Cortex A57 cores and four A53 cores. Huang didn't disclose clock speeds, but he did reveal that the thermal envelope is about 10W. The chip is built on 20-nm fabrication tech, and it can play 4K video at 60 FPS using either the H.265 or VP9 codecs.

Nvidia claims the Tegra X1 is the first mobile chip to deliver a teraflop of floating-point throughput. Unlike previous Tegra chips, the X1 supports floating-point datatypes with 16 bits of precision, otherwise known as FP16. This format should require less power to process than the FP32 format used by the Tegra K1.

Huang said the Tegra X1 is energy efficient thanks to its Maxwell roots, but it can also run state of the art engines that any desktop computer or next-gen console can run. With the Tegra X1, users are in for a console-like experience on their mobile devices.

Apparently, a powerful mobile chip. Dubbed the Tegra X1, the processor is super energy efficient while also packing enough power to run a desktop.
