Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs Radeon HD 5550
IntroThe GeForce 8600 GT 512MB DDR2 comes with a GPU core clock speed of 540 MHz, and the 512 MB of DDR2 memory runs at 400 MHz through a 128-bit bus. It also is comprised of 32 Stream Processors, 16 Texture Address Units, and 8 ROPs.Compare those specs to the Radeon HD 5550, which makes use of a 40 nm design. AMD has clocked the core speed at 550 MHz. The DDR2 memory runs at a frequency of 400 MHz on this particular model. It features 320(64x5) SPUs along with 16 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthBoth cards have the exact same memory bandwidth, so theoretically they should have identical performance. (explain)
Texel RateThe Radeon HD 5550 will be a little bit (more or less 2%) more effective at texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 5550 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 information (counted in megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
