Compare any two graphics cards:
GeForce 8600 GT 512MB GDDR3 vs Radeon HD 3650 512MB
IntroThe GeForce 8600 GT 512MB GDDR3 has clock speeds of 540 MHz on the GPU, and 700 MHz on the 512 MB of GDDR3 memory. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.Compare those specifications to the Radeon HD 3650 512MB, which makes use of a 55 nm design. AMD has set the core frequency at 725 MHz. The GDDR3 RAM works at a frequency of 800 MHz on this specific card. It features 120(24x5) SPUs along with 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 3650 512MB should be 14% faster than the GeForce 8600 GT 512MB GDDR3 overall, because of its greater data rate. (explain)
Texel RateThe GeForce 8600 GT 512MB GDDR3 will be much (about 49%) more effective at texture filtering than the Radeon HD 3650 512MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce 8600 GT 512MB GDDR3 is the winner, 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: Memory bandwidth is the largest amount of information (counted in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type 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 texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 ability to get to the max fill rate.
