AMD has just made a nice bump to its FirePro W9100 offering, with a new 32GB model joining the 16GB model that already had a ton of VRAM.
The AMD FirePro W9100 uses the same Hawaii GPU, featuring 2816 stream processors, 176 TMUs, and 64 ROPs. The FirePro W9100 with 16GB of VRAM features the same specs, with a 930MHz GPU clock, and its 32GB of GDDR5 VRAM clocked at 5GHz on a 512-bit memory bus.
It's baked onto the tried and true 28nm process, with 1/2 double precision, 6.2 billion transistors, and a 275W TDP. AMD offers FirePro W9100 owners a huge 3-year warranty, but so you should with its massive $4999 price tag.
