Moving to tech news now. The US graphics cards giant Nvidia has unveiled its most powerful AI supercomputer dubbed the DGX-2. The company's founder and CEO Jenson Huang announced the update to last years' DGX-1 supercomputer at the company's annual technology conference on Tuesday. The DGX-2 is geared towards machine learning and AI research much like its predecessor. The newest supercomputer, filled with top-of-the-line hardware, is theoretically ten times faster than the first generation. The DGX-2 is an expansion into the AI market by Nvidia and a consolidation of the company's leading status in the field. The machine doesn't come cheap. It's priced at about 400 thousand dollars.
