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

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 5830 is 122% faster than the GeForce 8800 GT 1GB in general, because of its greater bandwidth. (explain)
Texel RateThe Radeon HD 5830 should be quite a bit (approximately 33%) better at anisotropic filtering than the GeForce 8800 GT 1GB. (explain)
Pixel RateThe Radeon HD 5830 will be a lot (approximately 33%) faster with regards to AA than the GeForce 8800 GT 1GB, and capable of handling higher resolutions without slowing down too much. (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 max amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the 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 can be applied in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
