Compare any two graphics cards:
GeForce GTX 460 2GB vs Radeon HD 4870 512MB
IntroThe GeForce GTX 460 2GB comes with a GPU core clock speed of 675 MHz, and the 2048 MB of GDDR5 memory is set to run at 900 MHz through a 256-bit bus. It also is comprised of 336 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.Compare those specifications to the Radeon HD 4870 512MB, which features a core clock speed of 750 MHz and a GDDR5 memory speed of 900 MHz. It also makes use of a 256-bit bus, and uses a 55 nm design. It is comprised of 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have the exact same bandwidth, so theoretically they should perform exactly the same. (explain)
Texel RateThe GeForce GTX 460 2GB is quite a bit (more or less 26%) more effective at texture filtering than the Radeon HD 4870 512MB. (explain)
Pixel RateThe GeForce GTX 460 2GB should be much (more or less 80%) faster with regards to full screen anti-aliasing than the Radeon HD 4870 512MB, and also 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number 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 drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
