Almost four months have passed since Nvidia released its GeForce 8800-series graphics cards. Before finishing up its DirectX 10 desktop lineup with some mainstream derivatives, Nvidia has stopped over by the workstation sector and introduced a pair of G80-based Quadro FX graphics cards. The two cards are dubbed Quadro FX 5600 and Quadro FX 4600, and they look more or less identical to their desktop GeForce 8800-series counterparts. However, beneath the Quadro FX 5600’s cooler lies a whopping 1.5GB of GDDR3 memory, which is twice as much as what the GeForce 8800 GTX has to offer. The Quadro FX 5600 also outdoes the GeForce on peak fill rate with 19.2Gtexels/s instead of 18.4Gtexels/s, although peak memory bandwidth is a little lower (76.8GB/s, compared to 86.4GB/s for the 8800 GTX.)

As for the Quadro FX 4600, its fill rate is the same as that of the GeForce 8800 GTS (12Gtexels/s), but memory bandwidth is also a little lower (57.6GB/s instead of 64GB/s). That said, the Quadro FX 4600 packs 768MB of memory and a full 384-bit memory bus, just like the desktop GeForce 8800 GTX. Nvidia says the Quadro FX 4600 will retail for $1,995, while the Quadro FX 5600 will go for just one dollar shy of three grand.
