Compare any two graphics cards:
GeForce GTX 280 vs Radeon HD 5850
IntroThe GeForce GTX 280 has clock speeds of 602 MHz on the GPU, and 1107 MHz on the 1024 MB of GDDR3 RAM. It features 240 SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.Compare those specs to the Radeon HD 5850, which comes with GPU clock speed of 725 MHz, and 1024 MB of GDDR5 memory set to run at 1000 MHz through a 256-bit bus. It also features 1440(288x5) SPUs, 72 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 280 should theoretically be a small bit better than the Radeon HD 5850 in general. (explain)
Texel RateThe Radeon HD 5850 should be just a bit (more or less 8%) more effective at AF than the GeForce GTX 280. (explain)
Pixel RateIf using 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum 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 card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card 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 card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
