Compare any two graphics cards:
GeForce 8800 GT 512MB vs Radeon HD 5670
IntroThe GeForce 8800 GT 512MB makes use of a 65 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 memory works at a speed of 900 MHz on this specific card. It features 112 SPUs as well as 56 TAUs and 16 ROPs.
Compare that to the Radeon HD 5670, which features a GPU core clock speed of 775 MHz, and 1024 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is comprised of 400(80x5) Stream Processors, 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 a bit faster than the GeForce 8800 GT 512MB in general. (explain)
Texel RateThe GeForce 8800 GT 512MB will be quite a bit (approximately 117%) more effective at AF than the Radeon HD 5670. (explain)
Pixel RateThe GeForce 8800 GT 512MB should be much (about 55%) more effective at anti-aliasing than the Radeon HD 5670, and also should be capable of handling higher resolutions without slowing down too much. (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 data (measured in MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. 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 many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
