AMD FirePro V4900
When starting with the EnSight test from the older SPECViewPerf 9.0 release, the FirePro V4900 on the AMD Bulldozer system was performing right in line with the FirePro V5800, but not noticeably faster than the FirePro V4800.
Maya under SPECViewPerf 9 positioned the FirePro V4900 between the V4800 and V5800, but not close to the V5900 speeds.
Today's new FirePro part when running TCVIS on SPECViewPerf 9 pulled in front of the V4800, V5800, and V5900 workstation graphics cards.
