Compare any two graphics cards:
GeForce 8800 GTS (G80) 640MB vs Radeon HD 6750 1GB
IntroThe GeForce 8800 GTS (G80) 640MB makes use of a 90 nm design. nVidia has clocked the core frequency at 513 MHz. The GDDR3 memory runs at a frequency of 792 MHz on this specific card. It features 96 SPUs as well as 48 TAUs and 20 Rasterization Operator Units.Compare all of that to the Radeon HD 6750 1GB, which features core clock speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 720 SPUs along with 36 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 6750 1GB should in theory be a bit better than the GeForce 8800 GTS (G80) 640MB in general. (explain)
Texel RateThe Radeon HD 6750 1GB is a small bit (about 6%) more effective at anisotropic filtering than the GeForce 8800 GTS (G80) 640MB. (explain)
Pixel RateThe Radeon HD 6750 1GB is a little bit (about 13%) faster with regards to anti-aliasing than the GeForce 8800 GTS (G80) 640MB, and should be able to handle higher resolutions without slowing down too much. (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 largest amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses 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 high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units of the card by the core clock 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 one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card 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 Render Output Units by the the card's clock speed. 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 of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
