Compare any two graphics cards:
GeForce 8800 GTS (G80) 640MB vs Radeon HD 6750
IntroThe GeForce 8800 GTS (G80) 640MB has a GPU clock speed of 513 MHz, and the 640 MB of GDDR3 memory runs at 792 MHz through a 320-bit bus. It also features 96 Stream Processors, 48 TAUs, and 20 ROPs.Compare those specifications to the Radeon HD 6750, which features core speeds of 725 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 memory. It features 720 SPUs as well as 36 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6750, in theory, should be a bit faster than the GeForce 8800 GTS (G80) 640MB overall. (explain)
Texel RateThe Radeon HD 6750 is a little bit (about 6%) better at texture filtering than the GeForce 8800 GTS (G80) 640MB. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 6750 is the winner, but only just. (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 data (measured in MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 applied per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
