At CES in Las Vegas, Nvidia unveiled its next mobile "super chip": the Tegra X1. This thumbnail-sized doodad is the first phone-bound processor to push a teraflop of processing power.

It's got 256 processor cores and eight CPU cores, which are all fancy numbers that mean it can provide twice the performance of last years Tegra K1 and it way outclasses Apple's A8 chip.

Nvidia says the chip will first be used to power screens and systems in cars, but it will eventually be crammed into phones and tablets.

It supports "all major graphics standards", says Nvidia, "making it easier for developers to bring PC games to mobile." As such, Epic showed its Unreal Engine 4 tech demo Elemental, previously seen on PC and PS4, running on the X1.
