Compare any two graphics cards:
GeForce GTX 460 vs Radeon HD 5770
IntroThe GeForce GTX 460 comes with a GPU core clock speed of 675 MHz, and the 768 MB of GDDR5 memory is set to run at 900 MHz through a 192-bit bus. It also features 336 SPUs, 56 Texture Address Units, and 24 ROPs.
Compare that to the Radeon HD 5770, which features a clock speed of 850 MHz and a GDDR5 memory frequency of 1200 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.

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)
The GeForce GTX 460 should theoretically be just a bit faster than the Radeon HD 5770 in general. (explain)
Texel RateThe GeForce GTX 460 will be a bit (more or less 11%) better at AF than the Radeon HD 5770. (explain)
Pixel RateThe GeForce GTX 460 should be just a bit (about 19%) faster with regards to anti-aliasing than the Radeon HD 5770, and also capable of handling higher resolutions while still performing well. (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 maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units of the card by the core clock 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 number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
