Compare any two graphics cards:
GeForce 8800 GTS (G80) 640MB vs Radeon HD 4730
IntroThe GeForce 8800 GTS (G80) 640MB has clock speeds of 513 MHz on the GPU, and 792 MHz on the 640 MB of GDDR3 memory. It features 96 SPUs as well as 48 Texture Address Units and 20 ROPs.Compare all that to the Radeon HD 4730, which features a clock frequency of 700 MHz and a GDDR5 memory frequency of 900 MHz. It also uses a 128-bit memory bus, and uses a 55 nm design. It is comprised of 640(128x5) SPUs, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 8800 GTS (G80) 640MB will be 10% quicker than the Radeon HD 4730 overall, due to its higher data rate. (explain)
Texel RateThe GeForce 8800 GTS (G80) 640MB is a bit (about 10%) better at anisotropic filtering than the Radeon HD 4730. (explain)
Pixel RateThe GeForce 8800 GTS (G80) 640MB is quite a bit (about 83%) faster with regards to anti-aliasing than the Radeon HD 4730, and also able to handle higher resolutions better. (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 (in units of MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. 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 output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
