Nvidia launches what it describes as a "mobile super chip" at CES 2015-- the Tegra X1, a successor to the K1 mobile device processor featuring 256 GPU cores and an 8-core 64-bit CPU built on Maxwell architecture.
The company claims the Tegra X1 is the first mobile chip to reach throughput of up to 1 teraflop, making it as fast as a supercomputer from 2000-- if within a smaller and far more energy efficient package. To show off the chip's capabilities Nvidia showed off a real-time Unreal Engine 4 demo, with complicated 3D rendering demanding all of 10W to power.
Furthermore the chipset handles 4K video at 60Hz and 1080p video at 120Hz.
