Compare any two graphics cards:
GeForce GTX 460 1GB vs Radeon HD 5770
IntroThe GeForce GTX 460 1GB features a GPU core clock speed of 675 MHz, and the 1024 MB of GDDR5 memory is set to run at 900 MHz through a 256-bit bus. It also is made up of 336 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.
Compare those specs to the Radeon HD 5770, which features a core clock frequency of 850 MHz and a GDDR5 memory frequency of 1200 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It is comprised of 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.

GeForce GTX 460 1GB wins
(Based entirely on the benchmarks listed above)
When combining all game benchmark scores on this page together, the GeForce GTX 460 1GB wins overall, by 56 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)
In theory, the GeForce GTX 460 1GB should be 50% faster than the Radeon HD 5770 in general, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTX 460 1GB is a small bit (about 11%) faster with regards to anisotropic filtering than the Radeon HD 5770. (explain)
Pixel RateThe GeForce GTX 460 1GB should be a lot (approximately 59%) faster with regards to full screen anti-aliasing than the Radeon HD 5770, and also should be capable of handling higher 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 information (counted in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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.
