Details of Nvidia's upcoming top-of-the-range GeForce 7950 GX2 SLI graphics card have slipped out ahead of the part's launch, expected to take place early next month at the Computex show in Taipei, Taiwan.

According to a DailyTech report, the card contains two 7900 GTX GPUs each clocked at 500MHz. There's 1GB of GDDR 3 SDRAM - 512MB per core, presumably - on board clocked to 600MHz (1.2GHz effective).

The two-slot product provides two dual-link DVI outputs and an HD-capable TV-out port. The board supports the HDCP anti-piracy system, though board vendors will need to add an extra chip containing crypto keys to provide the technology to users.

Nvidia is pitching the part as the "fastest single graphics card in the world", the report states. The company claims performance gains of 15-80 per cent over the GeForce 7900 GTX at 1600 x 1200, 4x/8x. ®
