Compare any two graphics cards:
GeForce GTX 460 1GB vs Radeon HD 5870
IntroThe GeForce GTX 460 1GB has a GPU core speed of 675 MHz, and the 1024 MB of GDDR5 memory runs at 900 MHz through a 256-bit bus. It also is made up of 336 Stream Processors, 56 TAUs, and 32 ROPs.
Compare all that to the Radeon HD 5870, which uses a 40 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 memory is set to run at a frequency of 1200 MHz on this particular card. It features 1600(320x5) SPUs along with 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 should theoretically perform a lot faster than the GeForce GTX 460 1GB overall. (explain)
Texel RateThe Radeon HD 5870 should be much (approximately 80%) more effective at anisotropic filtering than the GeForce GTX 460 1GB. (explain)
Pixel RateThe Radeon HD 5870 is much (about 26%) better at AA than the GeForce GTX 460 1GB, and also able to handle higher screen 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: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 are processed per second. This number is worked out 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
