Compare any two graphics cards:
GeForce 8800 GTS (G92) vs Radeon HD 5770
IntroThe GeForce 8800 GTS (G92) makes use of a 65 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR3 memory works at a speed of 970 MHz on this model. It features 128 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.
Compare that to the Radeon HD 5770, which makes use of a 40 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 RAM runs at a frequency of 1200 MHz on this particular model. It features 800(160x5) SPUs as well as 40 TAUs and 16 ROPs.

Radeon HD 5770 wins
(Based entirely on the benchmarks listed above)
When combining all game benchmark scores on this page together, the Radeon HD 5770 wins overall, by 117 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 Radeon HD 5770 should theoretically be a lot superior to the GeForce 8800 GTS (G92) overall. (explain)
Texel RateThe GeForce 8800 GTS (G92) should be a lot (about 22%) more effective at AF than the Radeon HD 5770. (explain)
Pixel RateThe Radeon HD 5770 should be quite a bit (approximately 31%) more effective at AA than the GeForce 8800 GTS (G92), and also will be able to handle higher screen 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 max amount of information (in units of MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's 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 are applied per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher 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 graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
