The Card, Specs and Test

Our Radeon X800 GT happens to be made by PowerColor, and looks about the same as other X800's with the exception of the sticker on the heatsink. As we've mentioned in the past, however, it's not the looks, but the performance that makes a good part. Let's talk about the card specifications.

The X800 GT is kind of the compromise between the high end of ATI's X700 and low end of their X800 series. Specifically, it has the same number of pixel pipelines as the X700, but it has the memory bandwidth of the X800 Pro. We find this to be an interesting approach to bridging the gap between the X700 and X800, and are curious to see what kinds of performance we see. Here is a table comparing a few of the parts that we'll be testing.

 Card Comparison
 -  Pixel Pipelines  Vertex Pipelines  Core Clock  Memory Clock  Price
Radeon X800 GT: 8 6 470MHz 495MHz $160
Radeon X800: 12 6 390MHz 350MHz $200
GeForce 6600 GT: 8 3 500MHz 500MHz $160

We will also be testing the GeForce 6800 ($200) and the Radeon X800 XT ($325) to give us a better performance comparison. We chose these cards to test based on their relative closeness in price and performance. The Radeon X800 XT is an exception with its higher price, and it is included here for reference. The X800 XT will obviously dominate here in framerate except in tests which are severely CPU-limited (i.e. Unreal Tournament), as it represents much higher performance in graphics cards.

Note that the X800 GT, X800, 6800, and X800 XT all have a 256 bit memory bus, while the 6600 GT only has a 128 bit memory bus. This will theoretically give the X800 GT an edge over the 6600 GT in tests with higher resolutions and anti-aliasing enabled. Conversely, the X800 GT can't process as many pixels per clock due to its slower core clock (and lack of certain features like SM3.0), so games that require more processing power should do worse on the X800 GT than on the 6600 GT. This means that they basically compromise by giving us more of one thing and less of another in order to compete with the 6600 GT.

Here is the system configuration that we used in our tests:

MSI K8N Neo4 Platinum/SLI motherboard
AMD Athlon 64 FX-55 Processor
2x512MB OCZ 2-2-2-6 1T DDR400 RAM
Seagate 7200.7 120 GB Hard Drive
OCZ 600 W PowerStream Power Supply

    But how does the 6600gt compare in SCCT with SM3.0 on. It's not an unbiased test if you're not using the cards to the best of their abilities. SM3 was built to give a performance boost that would encourage people to by cards with it, no sense in leaving this out. Reply

    Remember the 6800 Strength lies in situations where AA & AF are applied. it's overall pixel fillrate is only 3.9GPixel compare to the 6600 GT 4.0GPixel, if not memory bandwidth limited, there is potential for 6600 GT to outperform 6800 Vanilla. Vertex Shader power doesn't matter also all that much as the amount 6600 GT has seems to be sufficient. Pixle Shader fillrate is one of the most important indicators of performance when comparing across the same architecture. Reply

    I was wondering about this myself. I've seen a number of benchmarks from other sources showing the 6800 to be the better performer. I hope Josh used a genuine NV41/42 6800 rather than just taking a NV45 and cutting it down. Reply

    hmm, could someone plz tell me what's the overclocking like with 6800s? is it worth buying at all? Reply

    they have different strengths Reply

    I just built a computer for a buddy a X800 GT 256MB card plus a A64 3500+ in it. The 3500+ overclocked to 2.63GHz prime95 stable, and the video card was running solid at 580Mhz Core 595Mhz Memory and looped 3dmark tests all night without a single problem. Probably the best bang for the buck system I've built so far. Performance wise better than the 3800+ and X800 XL system I built prior to it (stock speeds) and a lot cheaper. Reply

    dont see how the x800 gt was a quality mid range solution as the x800 xl and x800 were much better cards Reply
