Compare any two graphics cards:
GeForce GTX 460 1GB vs Radeon HD 5770
IntroThe GeForce GTX 460 1GB has a core clock speed of 675 MHz and a GDDR5 memory speed of 900 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It features 336 SPUs, 56 TAUs, and 32 Raster Operation Units.
Compare all that to the Radeon HD 5770, which makes use of a 40 nm design. AMD has clocked the core speed at 850 MHz. The GDDR5 RAM works at a frequency of 1200 MHz on this model. It features 800(160x5) SPUs as well as 40 TAUs 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 will be 50% faster than the Radeon HD 5770 overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 460 1GB is a bit (more or less 11%) more effective at anisotropic filtering than the Radeon HD 5770. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 460 1GB is superior to the Radeon HD 5770, by far. (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 maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 processed in one second. This number is calculated by multiplying the total amount 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
