Compare any two graphics cards:
GeForce GTX 460 1GB vs Radeon HD 6870
IntroThe GeForce GTX 460 1GB makes use of a 40 nm design. nVidia has set the core frequency at 675 MHz. The GDDR5 RAM is set to run at a frequency of 900 MHz on this card. It features 336 SPUs along with 56 TAUs and 32 ROPs.
Compare that to the Radeon HD 6870, which uses a 40 nm design. AMD has set the core speed at 900 MHz. The GDDR5 memory is set to run at a frequency of 1050 MHz on this particular card. It features 1120 SPUs as well as 56 TAUs and 32 ROPs.

(Based entirely on the benchmarks listed above)
When combining all game benchmark scores on this page together, the Radeon HD 6870 wins overall, by 21 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 6870, in theory, should be just a bit faster than the GeForce GTX 460 1GB in general. (explain)
Texel RateThe Radeon HD 6870 is a lot (more or less 33%) better at anisotropic filtering than the GeForce GTX 460 1GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 6870 is superior to the GeForce GTX 460 1GB, and very much so. (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 max amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 are processed per second. This number is worked out by multiplying the total number of texture units 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 processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
