Nvidia GeForce 7950 GT review: Nvidia GeForce 7950 GT

We considered Nvidia's GeForce 7900 GT the 3D card price-performance leader when we reviewed it back in the spring of this year. It was fast enough to do justice to most games on the market, and its $300 price tag didn't break the bank. We're less enthused about its fall update, the GeForce 7950 GT. This card also costs around $300 (you can find the 7900 GT for about $250 now), and it has twice the memory of its predecessor, with 512MB. Nvidia designed the GeForce 7950 GT to wear the price-performance crown, but compared to the similar ATI Radeon X1900 XT, the Nvidia card can't keep up to speed.

By the numbers, the GeForce 7950 GT looks strong but not as strong as the competition. Nvidia has a pixel pipeline advantage, dedicating 24 pipes to rendering dots on the screen compared to the Radeon X1900 XT's 16. But its clock speeds come in at 550MHz for the chip and 1.4GHz for the DDR3 memory. The Radeon 1900XT has a faster 625MHz core and a slight memory speed advantage at 1.44GHz. That translates to an overall performance win for ATI, even when we compare its newly released 256MB Radeon X1900 XT against the 512MB GeForce 7950 GT.

The only test the GeForce 7950 GT took from ATI was Futuremark's synthetic (that is, not representative of real-world gameplay) 3DMark06. On that benchmark, the GeForce 7950 GT landed right in the middle of the 256MB and 512MB versions of the Radeon X1900 XT. But on every test using an actual game, at least at 1,600x1,200, the GeForce 7950 GT fell behind. We're most surprised by its loss on Quake 4, which Nvidia used to dominate. At the more complex 1,920x1,440 resolution, the GeForce 7950 GT fared better on Half-Life 2: The Lost Coast, which indicated to us that if you use Nvidia's SLI technology to pair two GeForce 7950 GT cards together, you might get better performance at higher resolutions than you would applying ATI's competing CrossFire dual-card mode. We've long favored SLI for its price advantages and its more elegant all-internal implementation over CrossFire's external dongle anyway.
