Last year NVIDIA introduced a mobile processor with 192-core Kepler graphics. This year the company’s stepping up its game with the Tegra X1 chip.

It’s a 64-bit, 8-core mobile processor with 256-core Maxwell graphics: the same graphics technology used in the desktop and notebook graphics chips NVIDIA introduced in 2014.

NVIDIA says the processor can handle 4K video playback at 60 Hz video in H.265 and VP9 formats, supports the same game engines as desktop chips, and offers twice the performance-per-watt of last year’s NVIDIA Tegra K1 processor.

Up until now the chip had been known by its code-name, Arista.

Among other devices, NVIDIA is positioning the Tegra X1 as a processor for in-vehicle systems with multiple displays (for entertainment, navigation, and vehicle information) thanks to a new in-car controller system called NVIDIA Drive CX which includes the Tegra X1 chip and software that allows car makers to customize their own solutions.

NVIDIA is also launching a more powerful system called the Drive PX which has 2 Tegra X1 chips that can work in parallel or as redundant processors.

The Drive PX is designed for self-driving cars or vehicles with advanced assisted driving technology. The system can support up to 12 HD cameras and can process 1.3 billion pixels per second to create a model of the environment around the car so that your vehicle knows where it is in position to other objects so it can plot a safe driving path.

Want a more detailed look at the technology used in the NVIDIA Tegra X1? AnandTech reports the chip uses 4 ARM Cortex-A57 CPU cores, 4 lower-power Cortex-A53 cores, and NVIDIA’s own software for allowing them to work together (and with the Maxwell graphics cores). The site also has initial benchmark results and analysis.

  1. Probably a good chip to come :). It remains to see the reactions of Qualcomm and consort.
    Differential encoding framebuffer is what was introduced by AMD with Tonga as well

  2. And it makes everything obsolete!!! No one comes even close to the Nvidia Tegra X1!!! Intel Skylake Might but AMD has NO HOPE!!!! GO NVIDIA CRUSH AMD!!!!!!

  3. The NVidia K1 did not turn out to be the end all be all. For what ever reason from reading the forums the devices built with the K1 had screen lag, which makes no sense to me.

  4. I wonder what the Octane score will be with this chip. The AndEBench-Pro scores are about 20% better than the K1 A15 scores. Hopefully the Octane scores will be improved with about the same amount, which would put it at about 9100, which is better than current top of the line Atom Bay-Trail (Octane score of 8200)

    1. And I wonder at what power these numbers are measured. Active cooling is not such an issue in a car…
