Compare any two graphics cards:
GeForce 8800 GT 1GB vs Radeon HD 5830
IntroThe GeForce 8800 GT 1GB features a core clock frequency of 600 MHz and a GDDR3 memory speed of 900 MHz. It also features a 256-bit bus, and uses a 65 nm design. It features 112 SPUs, 56 Texture Address Units, and 16 ROPs.Compare all of that to the Radeon HD 5830, which features a clock speed of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 256-bit memory bus, and uses a 40 nm design. It is comprised of 1120(224x5) SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 5830 should theoretically perform much faster than the GeForce 8800 GT 1GB overall. (explain)
Texel RateThe Radeon HD 5830 will be much (more or less 33%) faster with regards to anisotropic filtering than the GeForce 8800 GT 1GB. (explain)
Pixel RateThe Radeon HD 5830 is quite a bit (about 33%) more effective at anti-aliasing than the GeForce 8800 GT 1GB, and will be capable of handling 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: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
