Compare any two graphics cards:
GeForce 8800 GTX vs GeForce 8800 Ultra
IntroThe GeForce 8800 GTX uses a 90 nm design. nVidia has set the core frequency at 575 MHz. The GDDR3 RAM runs at a speed of 900 MHz on this card. It features 128 SPUs as well as 64 TAUs and 24 Rasterization Operator Units.
Compare those specs to the GeForce 8800 Ultra, which features a clock speed of 612 MHz and a GDDR3 memory speed of 1080 MHz. It also features a 384-bit memory bus, and uses a 90 nm design. It is made up of 128 SPUs, 64 TAUs, and 24 ROPs.

GeForce 8800 Ultra wins
(Based entirely on the benchmarks listed above)
When combining all game benchmark scores on this page together, the GeForce 8800 Ultra wins overall, by 84 FPS. Please note that we do not have the results of every benchmark ever done for these cards, so the results may differ wildly in different games.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce 8800 Ultra should theoretically be a little bit better than the GeForce 8800 GTX in general. (explain)
Texel RateThe GeForce 8800 Ultra is a small bit (approximately 6%) faster with regards to AF than the GeForce 8800 GTX. (explain)
Pixel RateThe GeForce 8800 Ultra is just a bit (more or less 6%) faster with regards to FSAA than the GeForce 8800 GTX, and also should be able to handle higher resolutions more effectively. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
