Compare any two graphics cards:
GeForce 8600 GT 512MB GDDR3 vs Radeon HD 5830
IntroThe GeForce 8600 GT 512MB GDDR3 comes with a GPU core speed of 540 MHz, and the 512 MB of GDDR3 memory is set to run at 700 MHz through a 128-bit bus. It also features 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare all of that to the Radeon HD 5830, which comes with a core clock frequency of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 256-bit bus, and uses a 40 nm design. It features 1120(224x5) SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 5830 should in theory be quite a bit faster than the GeForce 8600 GT 512MB GDDR3 in general. (explain)
Texel RateThe Radeon HD 5830 should be much (more or less 419%) more effective at texture filtering than the GeForce 8600 GT 512MB GDDR3. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 5830 is the winner, 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 max amount of information (in units of megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
