Compare any two graphics cards:
GeForce 8800 GT 512MB vs Radeon HD 4850 2GB
IntroThe GeForce 8800 GT 512MB makes use of a 65 nm design. nVidia has set the core frequency at 600 MHz. The GDDR3 memory runs at a frequency of 900 MHz on this specific model. It features 112 SPUs along with 56 TAUs and 16 ROPs.Compare that to the Radeon HD 4850 2GB, which makes use of a 55 nm design. AMD has clocked the core speed at 625 MHz. The GDDR4 RAM is set to run at a frequency of 993 MHz on this card. It features 800(160x5) SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 4850 2GB should in theory be a little bit better than the GeForce 8800 GT 512MB overall. (explain)
Texel RateThe GeForce 8800 GT 512MB will be quite a bit (about 34%) more effective at texture filtering than the Radeon HD 4850 2GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 4850 2GB is superior to the GeForce 8800 GT 512MB, 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 (counted in MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high 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 amount of texture units by the core 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 applied in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core 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 is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
