Compare any two graphics cards:
GeForce GTX 460 1GB vs Radeon HD 5870
IntroThe GeForce GTX 460 1GB has a clock speed of 675 MHz and a GDDR5 memory speed of 900 MHz. It also features a 256-bit bus, and makes use of a 40 nm design. It features 336 SPUs, 56 TAUs, and 32 ROPs.
Compare that to the Radeon HD 5870, which makes use of a 40 nm design. AMD has set the core speed at 850 MHz. The GDDR5 RAM is set to run at a speed of 1200 MHz on this particular model. It features 1600(320x5) SPUs as well as 80 Texture Address Units and 32 Rasterization Operator Units.

Radeon HD 5870 wins
(Based entirely on the benchmarks listed above)
When combining all game benchmark scores on this page together, the Radeon HD 5870 wins overall, by 119 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 Radeon HD 5870, in theory, should perform much faster than the GeForce GTX 460 1GB overall. (explain)
Texel RateThe Radeon HD 5870 will be quite a bit (more or less 80%) better at texture filtering than the GeForce GTX 460 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 5870 is superior to the GeForce GTX 460 1GB, 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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum number 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 amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
