Compare any two graphics cards:
GeForce 8800 GT 512MB vs Radeon HD 5670
IntroThe GeForce 8800 GT 512MB has a core clock frequency of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 256-bit bus, and makes use of a 65 nm design. It is made up of 112 SPUs, 56 TAUs, and 16 ROPs.
Compare those specs to the Radeon HD 5670, which comes with a GPU core clock speed of 775 MHz, and 1024 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also features 400(80x5) SPUs, 20 TAUs, and 8 Raster Operation Units.

Radeon HD 5670 wins
(Based entirely on the benchmarks listed above)
When combining all game benchmark scores on this page together, the Radeon HD 5670 wins overall, by 7 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)
Theoretically speaking, the Radeon HD 5670 should be 11% faster than the GeForce 8800 GT 512MB in general, due to its greater data rate. (explain)
Texel RateThe GeForce 8800 GT 512MB will be much (more or less 117%) faster with regards to anisotropic filtering than the Radeon HD 5670. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce 8800 GT 512MB is a better choice, and very much so. (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: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
