Compare any two graphics cards:
GeForce 8800 GTS (G80) 320MB vs Radeon HD 6770
IntroThe GeForce 8800 GTS (G80) 320MB features a GPU core speed of 513 MHz, and the 320 MB of GDDR3 memory is set to run at 792 MHz through a 320-bit bus. It also features 96 SPUs, 48 TAUs, and 20 ROPs.Compare those specifications to the Radeon HD 6770, which makes use of a 40 nm design. AMD has set the core speed at 900 MHz. The GDDR5 memory runs at a speed of 1050 MHz on this particular card. It features 800 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 6770 should in theory be a little bit superior to the GeForce 8800 GTS (G80) 320MB in general. (explain)
Texel RateThe Radeon HD 6770 is a lot (approximately 46%) more effective at texture filtering than the GeForce 8800 GTS (G80) 320MB. (explain)
Pixel RateThe Radeon HD 6770 will be quite a bit (about 40%) better at anti-aliasing than the GeForce 8800 GTS (G80) 320MB, and should 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: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is calculated 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 a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour 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 rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
