Compare any two graphics cards:
GeForce GTX 460 (OEM) vs Radeon HD 5850
IntroThe GeForce GTX 460 (OEM) has a core clock speed of 650 MHz and a GDDR5 memory speed of 850 MHz. It also uses a 256-bit memory bus, and uses a 40 nm design. It is comprised of 336 SPUs, 56 TAUs, and 32 Raster Operation Units.Compare all of that to the Radeon HD 5850, which makes use of a 40 nm design. ATi has clocked the core frequency at 725 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this particular card. It features 1440(288x5) SPUs as well as 72 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 5850 should theoretically be a bit faster than the GeForce GTX 460 (OEM) overall. (explain)
Texel RateThe Radeon HD 5850 is much (more or less 43%) more effective at AF than the GeForce GTX 460 (OEM). (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 5850 is the winner, but not by far. (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.

Specifications
Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If 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 high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video 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 number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
