Compare any two graphics cards:
GeForce 8800 GTS (G80) 320MB vs Radeon HD 4730
IntroThe GeForce 8800 GTS (G80) 320MB uses a 90 nm design. nVidia has clocked the core frequency at 513 MHz. The GDDR3 RAM runs at a speed of 792 MHz on this specific card. It features 96 SPUs as well as 48 Texture Address Units and 20 ROPs.Compare those specs to the Radeon HD 4730, which has a clock frequency of 700 MHz and a GDDR5 memory speed of 900 MHz. It also features a 128-bit bus, and makes use of a 55 nm design. It features 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) 320MB will be 10% faster than the Radeon HD 4730 in general, because of its greater bandwidth. (explain)
Texel RateThe GeForce 8800 GTS (G80) 320MB will be a little bit (approximately 10%) more effective at AF than the Radeon HD 4730. (explain)
Pixel RateThe GeForce 8800 GTS (G80) 320MB is much (more or less 83%) faster with regards to anti-aliasing than the Radeon HD 4730, and also should be able to handle higher screen 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: Bandwidth is the largest amount of information (in units of MB per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling 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 can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
