Compare any two graphics cards:
GeForce GTX 460 vs Radeon HD 5770
IntroThe GeForce GTX 460 features core clock speeds of 675 MHz on the GPU, and 900 MHz on the 768 MB of GDDR5 RAM. It features 336 SPUs as well as 56 Texture Address Units and 24 Rasterization Operator Units.
Compare all of 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 speed of 1200 MHz on this particular model. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

GeForce GTX 460 wins
(Based entirely on the benchmarks listed above)
When combining all game benchmark scores on this page together, the GeForce GTX 460 wins overall, by 40 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)
As far as performance goes, the GeForce GTX 460 should theoretically be a small bit better than the Radeon HD 5770 overall. (explain)
Texel RateThe GeForce GTX 460 is a small bit (more or less 11%) better at AF than the Radeon HD 5770. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 460 is the winner, but it probably won't make a huge difference. (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 information (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 can be applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, 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 most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
