AMD FirePro V7900

Along with the mid-range AMD FirePro V5900 workstation graphics card, which was just reviewed here at Phoronix, this morning AMD is also announcing the FirePro V7900 as their newest high-end workstation graphics card. The FirePro V7900 is a big step-up from last year's FirePro V7800 and features the "Cayman Pro GL" graphics core. Here is our initial Linux tests of this new $999 USD graphics card.

The FirePro V7900 graphics card is a single-slot solution like the V7800, but this time around it bears four DisplayPort v1.2 connections and is upgraded to a Cayman family graphics processor compared to Cypress on last year's high-end model. There are 1280 Stream processors and 2GB of GDDR5.

While there is not any additional memory on the V7900 compared to the V7800 (where as the V5800 to V5900 transition doubled the RAM) and it remains on a 256-bit interface, there is 160GB/s of memory bandwidth on this new model compared to 128GB/s on last year's high-end version. The new Cayman graphics processor can also process over 1450 million triangles per second where as the V7800 taps out at just 700 million. It also supports the other new features of this year's FirePro models, which include AMD GeometryBoost, PowerTune, HD3D Pro, and Enhanced Quality Anti-Aliasing (EQAA). The V7900 has a 725MHz core clock and 1250MHz memory clock.
