Nvidia Corp. says its Drive PX 2 supercomputer's advanced artificial intelligence and graphics processing capabilities will help pave the way for fully autonomous vehicles.

The Santa Clara, Calif.-based company, which pioneered the use of separate graphic processing units for computers in 2007, detailed the second-generation PX 2 this week at the Consumer Electronics Show in Las Vegas.

The new computer, which is about the size of a lunchbox, features two Tegra GPUs with a combined processing power of 8 teraflops. Nvidia says this is equivalent to 150 MacBook Pros operating together and is about 10 times as powerful as the first-generation Drive PX introduced a year ago. The system, which draws about 250 watts, uses liquid cooling rather than fans to help bolster performance in hot weather.

The PX 2 can simultaneously process information from a dozen high-resolution video cameras, GPS, lidar, radar, ultrasonic sensors and other inputs. This allows self-driving vehicles to quickly and more precisely identify and analyze an array of complex traffic variables, according to the supplier.
