Compare any two graphics cards:
GeForce 8600 GT 256MB GDDR3 vs Radeon HD 3650
IntroThe GeForce 8600 GT 256MB GDDR3 features a GPU core clock speed of 540 MHz, and the 256 MB of GDDR3 memory runs at 700 MHz through a 128-bit bus. It also is made up of 32 SPUs, 16 TAUs, and 8 ROPs.Compare all that to the Radeon HD 3650, which has a core clock speed of 725 MHz and a GDDR4 memory frequency of 800 MHz. It also features a 128-bit memory bus, and makes use of a 55 nm design. It is comprised of 120(24x5) SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 3650 should theoretically be a little bit faster than the GeForce 8600 GT 256MB GDDR3 in general. (explain)
Texel RateThe GeForce 8600 GT 256MB GDDR3 should be much (more or less 49%) faster with regards to AF than the Radeon HD 3650. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce 8600 GT 256MB GDDR3 is the winner, by a large margin. (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 largest amount of information (measured in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
