As usual, NVidia has followed its release of the gamer-focussed GeForce 7800 GTX graphics chips with workstation-class processors. The Quadro FX 4500 is the company's highest-end graphics card, with the Quadro FX 3450 upgrading the popular Quadro FX 3000 chip.
The Quadro FX 4500 offers 50 per cent more power than its predecessor, the FX 4000, according to NVidia. It features 512MB of frame buffer memory, a 128-bit floating point buffer and 12-bit sub-pixel precision. By utilizing NVidia's SLI dual-card technology and a compliant motherboard, the 4500 enables support for 32x full-scene anti-aliasing, up to four displays running from a single system, and multiple GPUs matched using an optional G-Sync board.
The Quadro FX 3450 also supports NVidia's SLI technology.
Boards based on these chips, which will be built by PNY in the UK, have not yet been announced.
