Compare any two graphics cards:
GeForce 8600 GS (OEM) vs Radeon HD 5550
IntroThe GeForce 8600 GS (OEM) has a GPU core clock speed of 540 MHz, and the 256 MB of DDR2 memory is set to run at 400 MHz through a 128-bit bus. It also is comprised of 32 SPUs, 16 Texture Address Units, and 8 ROPs.Compare all that to the Radeon HD 5550, which has a GPU core clock speed of 550 MHz, and 512 MB of DDR2 RAM running at 400 MHz through a 128-bit bus. It also is comprised of 320(64x5) SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthBoth cards have exactly the same bandwidth, so theoretically they should perform the same. (explain)
Texel RateThe Radeon HD 5550 will be a bit (about 2%) faster with regards to texture filtering than the GeForce 8600 GS (OEM). (explain)
Pixel RateThe Radeon HD 5550 will be a bit (approximately 2%) better at full screen anti-aliasing than the GeForce 8600 GS (OEM), and capable of handling higher resolutions more effectively. (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 max amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 processed in one second. This figure is calculated by multiplying the total number of texture units by the core 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 applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
