Compare any two graphics cards:
GeForce GTX 580 vs Radeon HD 6850
IntroThe GeForce GTX 580 has a GPU clock speed of 772 MHz, and the 1536 MB of GDDR5 memory is set to run at 1002 MHz through a 384-bit bus. It also is comprised of 512 SPUs, 64 TAUs, and 48 Raster Operation Units.Compare all that to the Radeon HD 6850, which makes use of a 40 nm design. AMD has set the core frequency at 775 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this particular card. It features 960 SPUs as well as 48 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 580 should theoretically be a lot superior to the Radeon HD 6850 overall. (explain)
Texel RateThe GeForce GTX 580 is a lot (approximately 33%) more effective at AF than the Radeon HD 6850. (explain)
Pixel RateThe GeForce GTX 580 will be much (more or less 49%) faster with regards to full screen anti-aliasing than the Radeon HD 6850, and will be capable of handling higher screen resolutions without losing too much performance. (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 information (counted in megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If 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 amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the card will be at 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 chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
