Compare any two graphics cards:
GeForce 8800 GTS (G92) vs Radeon HD 4830 1GB
IntroThe GeForce 8800 GTS (G92) makes use of a 65 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR3 memory runs at a frequency of 970 MHz on this particular model. It features 128 SPUs as well as 64 TAUs and 16 ROPs.Compare those specs to the Radeon HD 4830 1GB, which uses a 55 nm design. AMD has clocked the core frequency at 575 MHz. The GDDR4 RAM runs at a speed of 900 MHz on this particular model. It features 640(128x5) SPUs as well as 32 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce 8800 GTS (G92) should perform a little bit faster than the Radeon HD 4830 1GB in general. (explain)
Texel RateThe GeForce 8800 GTS (G92) is quite a bit (about 126%) more effective at anisotropic filtering than the Radeon HD 4830 1GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce 8800 GTS (G92) is the winner, but not 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: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock 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 many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
