Compare any two graphics cards:
GeForce 8600 GS (OEM) vs Radeon HD 4550 256MB
IntroThe GeForce 8600 GS (OEM) makes use of a 80 nm design. nVidia has set the core frequency at 540 MHz. The DDR2 RAM runs at a speed of 400 MHz on this particular model. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.Compare those specifications to the Radeon HD 4550 256MB, which makes use of a 55 nm design. AMD has set the core frequency at 600 MHz. The DDR3 RAM is set to run at a frequency of 800 MHz on this particular card. It features 80(16x5) SPUs along with 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have exactly the same memory bandwidth, so in theory they should have the same performance. (explain)
Texel RateThe GeForce 8600 GS (OEM) is much (about 80%) more effective at texture filtering than the Radeon HD 4550 256MB. (explain)
Pixel RateThe GeForce 8600 GS (OEM) will be a lot (approximately 80%) better at anti-aliasing than the Radeon HD 4550 256MB, and able to handle higher screen resolutions without slowing down too much. (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 data (counted in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock 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 fill rate is also dependant on lots of 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.
