XFX GeForce 7900 GS 480M Extreme And 7950 GT - HotHardware

XFX GeForce 7900 GS 480M Extreme And 7950 GT

0 thumbs up

Over the course of the last few months, the vast majority of news coming through the doors of NVIDIA has been in regards to enthusiast-class products such as the GeForce 7950 GX2 GPU and nForce 570 chipset. However, today the company is launching two new GPUs aimed squarely at the more mainstream price segments of the gaming community. Here, we find the GeForce 7900 GS coming to market with an MSRP of $199 and the GeForce 7950 GT which carries an MSRP of $299. With these two GPUs, NVIDIA is providing the market with a direct response to ATI's recently announced and yet currently unavailable Radeon X1900 XT 256MB as well as the currently available Radeon X1800 GTO. In order to see which vendor's solution is preferable at the lower price point, we'll examine the features of the new GeForce 7900 GS in detail and we'll follow up with more information on the GeForce 7950 GT next week.

Based around a surprisingly small 196mm2 core manufactured on a 90u process, the GeForce 7900 GS operates with reference clock speeds of 450MHz/1.32GHz and is armed with an impressive list of features. The 7900 GS has 7 Vertex Shaders, 20 Pixel Pipelines, and 16 ROPs. Rounding out the specifications we also have a 256MB frame buffer that utilizes a 256-bit memory interface, full DX9 support including Shader Model 3.0, as well as NVIDIA's own PureVideo technology allowing for hardware-based video decode acceleration. Perhaps most importantly however, is the fact that the GeForce 7900 GS will be available today in volume at most major online and brick and mortar retailers. To that end, we will be examining a retail-ready XFX GeForce 7900 GS 480M Extreme (PVT71PUDE3) which comes out of the box overclocked to a healthy 480MHz/1.4GHz.

The XFX GeForce 7900 GS comes packaged in a vibrant retail box which has the card clearly exposed on the back panel. Here, we can clearly see that XFX has chosen to retain the reference heatsink assembly though there is still enough "eye candy" thanks to the card's colored PCB and custom graphic on the heatsink assembly.

   

The bundle for the XFX GeForce 7900 GS is rather minimalist, though this is hardly surprising considering the $199-$219 price point the GeForce 7900 GS is directed at. Regardless, we still find the bare essentials including a DVI to VGA adaptor, an S-Video cable, a PCI-Express power adaptor, as well as a driver CD and User's Manual.
