Nvidia Corp. may add a yet another model to its already successful GeForce 7900 lineup. Dell Inc., the world’s largest maker of personal computers, has already started to sell a product called GeForce 7900 GS, which is projected to fill the gap between the GeForce 7600 GT and the GeForce 7900 GT.

The GeForce 7900 GS has 20 pixel processors, 7 vertex processors and 256-bit memory bus. Dell sells GeForce 7900 GS graphics cards clocked at 470MHz/1320MHz for core/memory along with its XPS 600 gaming computers. The GeForce 7900 GS is powered by the latest graphics chip code-namedG71, thus, comes with dual-link DVI outputs and other advantages the G71 has over predecessors, particularly, very low power consumption.

The difference on Dell’s website between a single GeForce 7900GS and dual GeForce 7900GS setups was $250, so if the card ever hits the retail market we can expect to see a retail price around $250, notes DailyTech web-site.

Featuring the 20 pixel processors and 470MHz graphics chip speed, Nvidia GeForce 7900 GS will deliver performance a little below that of the GeForce 7900 GT. But being a cut-down version of the latter, the product may have very low power consumption, which may allow manufacturers of appropriate graphics boards to equip it with very low-speed low-noise fans or even stick to passive cooling solution. Being priced at $250, the product competes against ATI’s Radeon X1800 GTO, but also offers significant competition for the GeForce 7600 GT with extra features that cost over $200.
