PNY has launched its nVidia GeForce GTX 480 and 470 graphics cards - its take on nVidia's new Fermi graphics card architecture.

The PNY GeForce GTX 470 and GeForce GTX 480 cards support DirectX 11 straight out of the box, providing PhysX, CUDA, PureVideo and 3D Vision Surround Technology. These are nVidia technologies designed to provide gamers with "an immersive stereoscopic 3D experience".

The higher end card, the GeForce GTX 480, has 480 processing cores and a clock speed of 700MHz, a 1.401MHz shader clock, and a 18G46Mz memory clock. Boasting a huge 1.5GB of GDDR5 RAM and a 250 Watts, the GTX 480 looks set to cost around £419.

PNY's take on the nVidia GeForce GTX 470, meanwhile, has 448 processing cores and a slightly lower core clock speed of 607MHz. This is accompanied by a 1215MHz shader clock and a 1674MHz memory clock, a 320bit memory interface and 1.2GB of GDDR5 RAM. At £299, the PNY GTX 470 card is still no bargain, however.

Both cards include two dual-link DVI-I connections, along with Mini-HDMI. They've been designed to compete head-to-head with similar spec graphics cards from ATI, namely the Radeon HD5870 and the 5850.

ATI has had Direct X11 cards on the market for some time now. However, nVidia says the GTX 470 is claimed five-to-10 percent faster than the ATI HD5850. The GTX 480 holds a similar lead over the Radeon HD5870, according to nVidia.

The PNY GeForce GTX 470 and GTX 480 cards will be available in early April and will come with a three-year warranty.
