Compare any two graphics cards:
GeForce 8600 GS (OEM) vs Radeon HD 4650 512MB
IntroThe GeForce 8600 GS (OEM) uses a 80 nm design. nVidia has clocked the core speed at 540 MHz. The DDR2 memory is set to run at a frequency of 400 MHz on this particular card. It features 32 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.Compare that to the Radeon HD 4650 512MB, which comes with GPU core speed of 600 MHz, and 512 MB of DDR2 memory running at 500 MHz through a 128-bit bus. It also is comprised of 320(64x5) SPUs, 32 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 4650 512MB should perform much faster than the GeForce 8600 GS (OEM) in general. (explain)
Texel RateThe Radeon HD 4650 512MB should be much (more or less 122%) better at anisotropic filtering than the GeForce 8600 GS (OEM). (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 4650 512MB is the winner, not by a very large margin though. (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 data (in units of MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per 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. The figure is worked out by multiplying the amount of ROPs by the the core 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 many 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.
