Compare any two graphics cards:
GeForce 8800 GTS (G80) 640MB vs Radeon HD 6770 1GB
IntroThe GeForce 8800 GTS (G80) 640MB comes with a core clock frequency of 513 MHz and a GDDR3 memory speed of 792 MHz. It also makes use of a 320-bit memory bus, and makes use of a 90 nm design. It features 96 SPUs, 48 TAUs, and 20 ROPs.Compare those specifications to the Radeon HD 6770 1GB, which has a clock speed of 900 MHz and a GDDR5 memory frequency of 1050 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is comprised of 800 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6770 1GB should be 6% faster than the GeForce 8800 GTS (G80) 640MB in general, due to its greater bandwidth. (explain)
Texel RateThe Radeon HD 6770 1GB is much (approximately 46%) better at anisotropic filtering than the GeForce 8800 GTS (G80) 640MB. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 6770 1GB is superior to the GeForce 8800 GTS (G80) 640MB, by far. (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 maximum amount of information (measured in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better 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 texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. 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 also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
