The widespread Nvidia G71 chip features superb overclockability, besides everything else. Its frequency was 650MHz for the main subunits and 700MHz for the vertex shader processors on the GeForce 7900 GTX, but that graphics card is already out of production and is to be replaced with the GeForce 8800 GTS 320MB model, a solution featuring a new-generation GPU. However, the GeForce 7900 GTX has a younger brother, the GeForce 7950 GT, described in our earlier review called Nvidia GeForce 7950 GT Graphics Card Review and highly appreciated by overclockers.

Lower in the product hierarchy there is the GeForce 7900 GS model which is based on the G71, too, but has much more modest technical characteristics. Our tests showed that working at its default GPU and memory frequencies the GeForce 7900 GS is far slower than its opponent in the same price category, the ATI Radeon X1950 Pro. You can now find Nvidia’s solution at reduced prices in retail shops, yet this doesn’t help it much.

But considering the overclockability of the G71 chip, which can generally work at frequencies above 550MHz, the release of pre-overclocked versions of the GeForce 7900 GS was inevitable. After all, not all gamers can or want to overclock their graphics card by themselves. One such pre-overclocked card has been introduced by ASUS. The GPU frequency of the EN7900GS Top is raised far above the default and the manufacturer claims a 20% performance increase over the reference 7900 GS. The EN7900GS Top thus seems to be lifted up to the same level with the GeForce 7950 GT. Is it really so and can ASUS be offering two products in the same market niche?

We decided to check it all out by benchmarking the EN7900GS Top in comparison with ASUS’ EN7950GT, which is a version of Nvidia’s GeForce 7950 GT.
