Compare any two graphics cards:
GeForce GTX 460 1GB vs Radeon HD 5870
IntroThe GeForce GTX 460 1GB uses a 40 nm design. nVidia has set the core speed at 675 MHz. The GDDR5 RAM is set to run at a frequency of 900 MHz on this specific model. It features 336 SPUs along with 56 TAUs and 32 ROPs.
Compare those specs to the Radeon HD 5870, which makes use of a 40 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 RAM works at a speed of 1200 MHz on this card. It features 1600(320x5) SPUs along with 80 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Radeon HD 5870 is 33% quicker than the GeForce GTX 460 1GB in general, due to its higher data rate. (explain)
Texel RateThe Radeon HD 5870 should be quite a bit (approximately 80%) better at texture filtering than the GeForce GTX 460 1GB. (explain)
Pixel RateThe Radeon HD 5870 is much (approximately 26%) faster with regards to full screen anti-aliasing than the GeForce GTX 460 1GB, and should be able to handle higher resolutions more effectively. (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 information (measured in megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units by the core 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 in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount 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 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 bandwidth is, the lower the potential to reach the maximum fill rate.
