Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs Radeon HD 3650 512MB
IntroThe GeForce 8600 GT 512MB DDR2 comes with a GPU core 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 SPUs, 16 Texture Address Units, and 8 ROPs.Compare those specs to the Radeon HD 3650 512MB, which features a clock frequency of 725 MHz and a GDDR3 memory speed of 800 MHz. It also features a 128-bit memory bus, and uses a 55 nm design. It features 120(24x5) SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 3650 512MB will be 100% quicker than the GeForce 8600 GT 512MB DDR2 in general, because of its higher bandwidth. (explain)
Texel RateThe GeForce 8600 GT 512MB DDR2 will be much (more or less 49%) better at anisotropic filtering than the Radeon HD 3650 512MB. (explain)
Pixel RateThe GeForce 8600 GT 512MB DDR2 should be a lot (more or less 49%) more effective at FSAA than the Radeon HD 3650 512MB, and also 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: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
