Compare any two graphics cards:
GeForce 8800 GTX vs Radeon HD 6870
IntroThe GeForce 8800 GTX makes use of a 90 nm design. nVidia has clocked the core frequency at 575 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this specific card. It features 128 SPUs along with 64 TAUs and 24 Rasterization Operator Units.Compare those specifications to the Radeon HD 6870, which comes with a core clock speed of 900 MHz and a GDDR5 memory frequency of 1050 MHz. It also features a 256-bit memory bus, and makes use of a 40 nm design. It features 1120 SPUs, 56 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 6870 should theoretically be a lot superior to the GeForce 8800 GTX overall. (explain)
Texel RateThe Radeon HD 6870 should be quite a bit (approximately 37%) more effective at AF than the GeForce 8800 GTX. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 6870 is the winner, by a large margin. (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: Bandwidth is the largest amount of data (measured in MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 most pixels the graphics card can possibly record to the local memory in one 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 clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
