Compare any two graphics cards:
GeForce GTX 460 1GB vs Radeon HD 5870
IntroThe GeForce GTX 460 1GB comes with a clock speed of 675 MHz and a GDDR5 memory frequency of 900 MHz. It also uses a 256-bit memory bus, and makes use of a 40 nm design. It is comprised of 336 SPUs, 56 Texture Address Units, and 32 ROPs.
Compare those specifications to the Radeon HD 5870, which features a core clock speed of 850 MHz and a GDDR5 memory speed of 1200 MHz. It also features a 256-bit memory bus, and uses a 40 nm design. It features 1600(320x5) SPUs, 80 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon HD 5870 will be 33% faster than the GeForce GTX 460 1GB overall, due to its higher bandwidth. (explain)
Texel RateThe Radeon HD 5870 will be much (approximately 80%) faster with regards to anisotropic filtering than the GeForce GTX 460 1GB. (explain)
Pixel RateThe Radeon HD 5870 will be quite a bit (about 26%) more effective at full screen anti-aliasing than the GeForce GTX 460 1GB, and also will be able to handle higher resolutions without slowing down too much. (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 (in units of MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one 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 higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
