Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs Radeon HD 4830 512MB
IntroThe GeForce 8600 GT 512MB DDR2 makes use of a 80 nm design. nVidia has clocked the core speed at 540 MHz. The DDR2 memory runs at a frequency of 400 MHz on this card. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.Compare that to the Radeon HD 4830 512MB, which has a GPU core clock speed of 575 MHz, and 512 MB of GDDR3 memory set to run at 900 MHz through a 256-bit bus. It also is comprised of 640(128x5) Stream Processors, 32 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 4830 512MB should in theory perform much faster than the GeForce 8600 GT 512MB DDR2 in general. (explain)
Texel RateThe Radeon HD 4830 512MB will be quite a bit (approximately 113%) better at anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateThe Radeon HD 4830 512MB will be much (approximately 113%) faster with regards to AA than the GeForce 8600 GT 512MB DDR2, and should be capable of handling higher resolutions without losing too much performance. (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 maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are 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 better this number, the better the 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 could 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 Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
