It's official - Nvidia has just launched the GeForce FX 5950 Ultra chip and the GeForce FX 5700 family, the first Nvidia processors to roll off IBM's 130nm 300mm wafer fab in East Fishkill, New York.

The 130nm 5950 - also known by its codename, 'NV38' - and is being pitched as the leading 5900-series chip. As we reported earlier today, its 256-bit, eight-pipeline core operates with 950MHz DDR graphics memory across a 256-bit bus yielding a bandwidth of 30.4GBps.

Nvidia's official figures for the 5650's performance are 3.8 billion texels per second and 356 million vertices per second. With Creative quoting four billion and 375 million for those measurements, respectively, it seems likely that the 500MHz 5950 running on its 3D Blaster 5 board is clocked higher than the 5950 standard.

The 5700 family - aka NV36 - replace the 5600 line of mainstream chips. Like the 5950, the 5700 Ultra is based on the CineFX 2 engine, but provides only four pixel pipelines rather than eight. It also supports a 128-bit memory bus, which yields a bandwidth of 14.4GBps when the DDR SDRAM operates at 900MHz.

The 5700 Ultra can churn out 1.9 billion pixels per second and 356 million vertices per second. Both the 5700 and the 5950 support up to 256MB of graphics memory.

Add-in cards based on the new GPUs are available from the likes of AOpen, Abit, Chaintech, Creative Labs, Gigabyte, Inno3D, Leadtek, MSI, PNY, Sparkle, Terratec, and XFX. ®
