Spokesperson for NVIDIA Corporation told X-bit labs some important notes about the Quadro FX 4000 graphics product for professional users that were absent from the original information available on the web.
Apparently, the Quadro FX 4000 is not based on the GeForce 6800 Ultra graphics processors, but is powered by a chip called NV40GL that is actually a superset of the NV40 – the heart of the GeForce 6800-series graphics processors – that features “lots more with hardware/silicon additions” and numerous software additions. Designed for professional CAD, DCC, and scientific applications, Quadro FX 4000 delivers 7%, 8% and 45% improvements in proe-02, 3dsmax-02 and ugs-03 professional benchmarks respectively over the predecessor Quadro FX 3000, according to NVIDIA.
The Quadro FX 4000 graphics cards feature 256MB of GDDR3 onboard memory functioning at 1000MHz. The cards also feature two DVI-I connectors to drive multiple very high-resolution displays at up to 3840x2400 resolution rates, satisfying demanding medical, satellite, and geospatial imaging application requirements.
