Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs Radeon HD 3850 1GB
IntroThe GeForce 8600 GT 512MB DDR2 features a GPU clock speed of 540 MHz, and the 512 MB of DDR2 RAM is set to run at 400 MHz through a 128-bit bus. It also is made up of 32 Stream Processors, 16 TAUs, and 8 Raster Operation Units.Compare that to the Radeon HD 3850 1GB, which features clock speeds of 668 MHz on the GPU, and 828 MHz on the 1024 MB of GDDR3 memory. It features 320(64x5) SPUs as well as 16 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 3850 1GB should in theory perform a lot faster than the GeForce 8600 GT 512MB DDR2 in general. (explain)
Texel RateThe Radeon HD 3850 1GB will be much (more or less 24%) better at anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 3850 1GB is a better choice, and very much so. (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 data (in units of megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's bus 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 higher the card's memory bandwidth, the faster 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 processed in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units 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 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 potential to get to the max fill rate.
