Compare any two graphics cards:
GeForce 8800 GTX vs GeForce 8800 Ultra
IntroThe GeForce 8800 GTX comes with clock speeds of 575 MHz on the GPU, and 900 MHz on the 768 MB of GDDR3 memory. It features 128 SPUs as well as 64 Texture Address Units and 24 ROPs.
Compare those specs to the GeForce 8800 Ultra, which uses a 90 nm design. nVidia has set the core frequency at 612 MHz. The GDDR3 memory works at a speed of 1080 MHz on this model. It features 128 SPUs along with 64 Texture Address Units and 24 Rasterization Operator Units.

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)
The GeForce 8800 Ultra should in theory be a little bit faster than the GeForce 8800 GTX overall. (explain)
Texel RateThe GeForce 8800 Ultra will be a small bit (about 6%) better at AF than the GeForce 8800 GTX. (explain)
Pixel RateThe GeForce 8800 Ultra should be a small bit (about 6%) faster with regards to full screen anti-aliasing than the GeForce 8800 GTX, and also should be able to handle higher screen resolutions better. (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 (measured in megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
