Did you think NVIDIA's newest Titan X was a monster of a video card? You haven't seen anything yet. The GPU maker has unveiled its latest Quadro workstation cards, the Pascal-based P5000 and P6000, and they both pack power that makes your gaming-grade card seem modest. The P6000 (above) is billed as the fastest graphics card to date, and for good reason. It has even more processing cores than the Titan X (3,840 versus 3,584) and twice as much memory -- a whopping 24GB of RAM. The P5000 is closer to the GTX 1080 in performance with "just" 2,560 cores, but its 16GB of RAM handily bests the gaming card's 8GB. If you're working with massive amounts of 3D data, these are likely the boards you want.
