Compare any two graphics cards:
GeForce 8800 GTS (G80) 320MB vs Radeon HD 3850 512MB
IntroThe GeForce 8800 GTS (G80) 320MB comes with a core clock speed of 513 MHz and a GDDR3 memory speed of 792 MHz. It also uses a 320-bit memory bus, and makes use of a 90 nm design. It features 96 SPUs, 48 Texture Address Units, and 20 ROPs.Compare that to the Radeon HD 3850 512MB, which features GPU core speed of 668 MHz, and 512 MB of GDDR3 RAM running at 828 MHz through a 256-bit bus. It also features 320(64x5) SPUs, 16 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 8800 GTS (G80) 320MB should be 20% quicker than the Radeon HD 3850 512MB in general, due to its greater bandwidth. (explain)
Texel RateThe GeForce 8800 GTS (G80) 320MB should be a lot (more or less 130%) better at anisotropic filtering than the Radeon HD 3850 512MB. (explain)
Pixel RateThe Radeon HD 3850 512MB should be a small bit (approximately 4%) more effective at full screen anti-aliasing than the GeForce 8800 GTS (G80) 320MB, and also will be capable of handling higher resolutions while still performing well. (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 (counted in megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units of the card 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 amount of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
