Compare any two graphics cards:
GeForce 8800 GTS (G80) 320MB vs Radeon HD 3870 1GB
IntroThe GeForce 8800 GTS (G80) 320MB comes with a clock frequency of 513 MHz and a GDDR3 memory speed of 792 MHz. It also uses a 320-bit bus, and makes use of a 90 nm design. It features 96 SPUs, 48 TAUs, and 20 ROPs.Compare those specs to the Radeon HD 3870 1GB, which features core clock speeds of 775 MHz on the GPU, and 1125 MHz on the 1024 MB of GDDR4 RAM. It features 320(64x5) SPUs along with 16 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 3870 1GB should be a little bit faster than the GeForce 8800 GTS (G80) 320MB in general. (explain)
Texel RateThe GeForce 8800 GTS (G80) 320MB is much (about 99%) faster with regards to anisotropic filtering than the Radeon HD 3870 1GB. (explain)
Pixel RateThe Radeon HD 3870 1GB is much (approximately 21%) better at full screen anti-aliasing than the GeForce 8800 GTS (G80) 320MB, and will be capable of handling higher screen resolutions better. (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 max amount of data (measured in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 number of texture map elements (texels) that are 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 in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. 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 reach the maximum fill rate.
