Compare any two graphics cards:
GeForce GTX 460 vs Radeon HD 5770
IntroThe GeForce GTX 460 makes use of a 40 nm design. nVidia has set the core frequency at 675 MHz. The GDDR5 RAM works at a speed of 900 MHz on this particular model. It features 336 SPUs along with 56 Texture Address Units and 24 ROPs.
Compare that to the Radeon HD 5770, which makes use of a 40 nm design. AMD has set the core speed at 850 MHz. The GDDR5 memory is set to run at a frequency of 1200 MHz on this specific card. It features 800(160x5) SPUs as well as 40 TAUs 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)
Theoretically speaking, the GeForce GTX 460 should perform a small bit faster than the Radeon HD 5770 overall. (explain)
Texel RateThe GeForce GTX 460 should be a small bit (more or less 11%) better at AF than the Radeon HD 5770. (explain)
Pixel RateThe GeForce GTX 460 will be a little bit (more or less 19%) faster with regards to FSAA than the Radeon HD 5770, and able to handle higher screen resolutions without losing too much performance. (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 data (in units of MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
