Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs Radeon HD 4550 512MB
IntroThe GeForce 8600 GT 512MB DDR2 uses a 80 nm design. nVidia has clocked the core frequency at 540 MHz. The DDR2 memory runs at a speed of 400 MHz on this specific model. It features 32 SPUs as well as 16 TAUs and 8 ROPs.Compare all of that to the Radeon HD 4550 512MB, which makes use of a 55 nm design. AMD has set the core speed at 600 MHz. The GDDR3 RAM works at a speed of 800 MHz on this particular model. It features 80(16x5) SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have the exact same bandwidth, so theoretically they should perform the same. (explain)
Texel RateThe GeForce 8600 GT 512MB DDR2 is a lot (about 80%) faster with regards to AF than the Radeon HD 4550 512MB. (explain)
Pixel RateThe GeForce 8600 GT 512MB DDR2 is quite a bit (more or less 80%) better at anti-aliasing than the Radeon HD 4550 512MB, and will be able to handle higher 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 (in units of megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the 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 - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
