Nvidia unwraps PCI Express graphics chips

GeForce FX PCX

Nvidia today officially unveiled its first PCI Express-oriented graphics chips, dropping the 'FX' from its current top-end GeForce series chips and replacing it with 'PCX'.

Four graphics processors will carry the tag: the GeForce PCX 5950, the GeForce PCX 5750, the GeForce PCX 5300 and the GeForce PCX 4300, aimed at the enthusiast, performance, mainstream and value markets, respectively.

The GPUs essentially match existing parts, but come with extra circuitry to convert their AGP 8x buses to PCI Express 16x. Nvidia dubs this protocol conversion technology HSI - High-Speed Interconnect.

Nvidia did not release core and memory performance specs. for the new products, so it's not clear how they stack up alongside other chips targeting the same market sectors.

The company said it has already shopped over 1000 PCI Express boards to customers and partners for validation. End-user products based on the new GPUs are expected to come to market in the second half of the year. Albatron, AOpen, Anextek, ASUS, Chaintech, Gainward, Gigabyte, Leadtek, MSI, Palit, Pine, Prolink and Sparkle are already signed up to offer Nvidia PCI Express boards. ®
