Compare any two graphics cards:
GeForce 8600 GT 256MB GDDR3 vs Radeon HD 3650 512MB
IntroThe GeForce 8600 GT 256MB GDDR3 uses a 80 nm design. nVidia has clocked the core speed at 540 MHz. The GDDR3 RAM runs at a speed of 700 MHz on this card. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.Compare those specifications to the Radeon HD 3650 512MB, which comes with a GPU core clock speed of 725 MHz, and 512 MB of GDDR3 RAM running at 800 MHz through a 128-bit bus. It also is comprised of 120(24x5) SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 3650 512MB should in theory be a little bit faster than the GeForce 8600 GT 256MB GDDR3 in general. (explain)
Texel RateThe GeForce 8600 GT 256MB GDDR3 is quite a bit (about 49%) more effective at AF than the Radeon HD 3650 512MB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce 8600 GT 256MB GDDR3 is superior to the Radeon HD 3650 512MB, 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 transferred across the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
