The two new GPUs are based on the Cayman GL architecture. The V5900 has 512 stream processors while the V7900 has 1280 stream processors. Each card has 2gb of GDDR5 memory with a 256-bit memory interface. The V5900 can push 1200 MTriangles/s and the V7900 an impressive 1450 MTriangles/s.
Here’s where things get cool, though: Each card is a single slot solution, and each supports Eyefinity. The V5900 sips power daintily at a mere 75W and the V7900 tops out at 150W. This is possible because of some frankly incredible advancements in power technology which we’ll get to in a moment. The V5900 has two DisplayPort 1.2 ports and 1 dual-link DVI and can run three displays with Eyefinity, while the V7900 has four DisplayPort 1.2 ports and can push four displays. This generation of FirePro are the first workstation GPUs to support the new DisplayPort 1.2 spec, as well.
The list price of the V5900 is $599 and the V7900 comes in at $999.
