That's computer aided design.
The V8650, V8600, V7600, V5600 and V3600 boards can use up to 320 individual stream processing units.
Features include 2GB on memory on the cards, and AMD-ATI claims the V5600 gives over 300 per cent the performance of the V5200 using the Viewperf 9.0.3 UGS Teamcentre Visualisation mockup benchmark test.
Prices are not cheap - these are workstation boards, and cost $2,800, $1,900, $1,000, $600 and $300 respectively with memory sizes 2GB, 1GB, 512MB, 512MB and 256MB in turn. ยต
