NVIDIA unveiled a few new PCI Express graphics cards for professional users, based on the GeForce FX and GeForce 6800 technology. These can now be used in the latest workstations with Intel Xeon processors and PCI Express x16 slots.
The company's new professional graphics cards lineup includes the following cards: The Quadro FX 4400 and Quadro FX 4400g which are based on the GeForce 6800, and thus support Shader Model 3.0. Further NVIDIA also released the Quadro FX 1400 and 540 which are based on the GeForce FX architecture.
All of these operate with PCI Express using a special bridge chip called High-Speed Interface.
NVIDIA’s Quadro FX 4400 features 512MB of GDDR3 frame buffer memory clocked at 1100MHz, a 256-bit memory interface, 3-pin stereo support, and dual DVI display connectors. The FX 4400G adds genlock and framelock capabilities to above mentioned features. Both Quadro FX 4400-series graphics cards are capable of working in so-called SLI mode. SLI is a technology that enables two NVIDIA Quadro FX graphics cards to operate in a single workstation delivering higher graphics horsepower.
NVIDIA’s new series of Quadro FX PCI Express x16 lineup is being demonstrated at Siggraph 2004 conference in Los Angeles, California. Commercial availability of the family is expected at a later date.
