CES 2015 jumps off tomorrow, but just like last year Nvidia is ready to show off their latest and greatest of what they have to offer for the coming year in the world of mobile computing and computing in general. We’re live at the Nvidia CES 2015 press event so stay tuned to the live blog here for the latest Nvidia details.

Nvidia has just announced the next generation of their Tegra chip, the Tegra X1 CPU which combines 64-bit ARM based CPU with a GPU based on the company’s Maxwell architecture. The Nvidia Tegra X1 will opt for the Maxwell GPU architecture instead of the Kepler architecture found inside of the Tegra K1 from last year. Nvidia states that the Maxwell architecture is “unquestionably the most powerful GPU we’ve ever built.”

With Tegra X1, Nvidia was able to achieve power and performance that is more than 1.5x greater than that of the powerhouse Tegra K1 chip from last year.

Tegra X1 is the world’s first mobile superchip to achieve 1 teraflops in mobile computing. It features 256 core maxwell GPU’s inside of an 8-core 64-bit CPU architecture. One of the first devices being powered by the Tegra X1 chip will be Nvidia’s Drive CX Cockpit computer, which Nvidia envisions being the at the forefront of future automotive computing. With the Nvidia Drive CX powered by the Tegra X1 mobile superchip, possibilities for some pretty cool and functional computerized dashboards are endless.

One such example has Nvidia display the power of the Drive CX and the Drive Studio platform(Nvidia’s software that designers can work with to create engaging and beautiful dashboard setups)by showing the dashboard take on designs of different simulated materials, like Bamboo as you can see in the image below.

Drive CX is truly a great advancement in automotive computing itself, but Nvidia also announced the Drive PX system today, it’s autopilot computer platform for self driving cars with 2.3 teraflops of mobile computing power. The Nvidia Drive PX system is powered by two Nvidia Tegra X1 chips, with full CUDA programmability and 12 camera inputs. Nvidia believes that for cars to reach a self driving state, there will have to be a network of connected cameras surrounding the vehicle, and all will need to be connected to a single unit or computer. The Nvidia Drive PX allows for this type of capability.
