XFX 9800GX2 Review

» Discuss this article (27)


At OverclockersClub.com, we use a series of benchmarks to stress the graphics card. We will use a series of newer, as well as a few more seasoned, gaming benchmarks to show how well the XFX 9800GX2 compares to some of the other enthusiast video cards on the market. All driver settings and clockspeeds will be left at factory default settings on both the CPU and GPU to minimize or eliminate any variables from impacting the results. The test system used in this review is listed below. After testing the card at stock speeds, I will overclock the video card to see what kind of performance can be gained. All testing is done with the default settings in the respective control panels as well as default settings in the BIOS of the motherboard used in this test.

  • XFX 9800 GX2 768/1106

Overclocking the XFX 9800GX2 was fairly simple. Just keep ratcheting up the clocks and the scores keep going up. I figured with a core speed of 600MHz I might be able to push to 700MHz. I went well beyond that and hit 768MHz, a 168MHz improvement over stock. The memory scaled very nicely as well, reaching 1106MHz, or 206MHz over the stock settings. The shader clocks scaled along with the core and ended up at 1944MHz. All things told, I was amazed at the increases in the clock speeds. The overclocked scores in this review do not tell all of the story. Sure there are increases in performance over the stock settings, but the CPU is the ultimate limitation with this kind of increase. I run the CPU at stock speeds and show the results good or bad for the sake of consistancy and to show what the average person can expect performance-wise. Just for kicks I wanted to see how it would do with a modest CPU overclock as well as the overclock on the 9800GX2. A 3DMark06 score of 18650 on stock air cooling was the result. No fan speed increase to help compensate for the temperature increase or any other tricks. 18650 with no OS tweaks is pretty sweet on a stock air cooled card. Oooh...the potential.
