Compare any two graphics cards:
GeForce 8800 GTS (G80) 320MB vs Radeon HD 6770 1GB
IntroThe GeForce 8800 GTS (G80) 320MB makes use of a 90 nm design. nVidia has set the core speed at 513 MHz. The GDDR3 RAM runs at a speed of 792 MHz on this particular card. It features 96 SPUs along with 48 TAUs and 20 Rasterization Operator Units.Compare all that to the Radeon HD 6770 1GB, which uses 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 BandwidthTheoretically speaking, the Radeon HD 6770 1GB is 6% faster than the GeForce 8800 GTS (G80) 320MB overall, due to its greater data rate. (explain)
Texel RateThe Radeon HD 6770 1GB should be quite a bit (more or less 46%) better at AF than the GeForce 8800 GTS (G80) 320MB. (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) 320MB, by a large margin. (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 data (measured in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 processed per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can 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 Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
