Compare any two graphics cards:
GeForce 8600 GT 256MB DDR2 vs Radeon HD 5450
IntroThe GeForce 8600 GT 256MB DDR2 has a GPU core speed of 540 MHz, and the 256 MB of DDR2 RAM runs at 400 MHz through a 128-bit bus. It also features 32 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.Compare those specifications to the Radeon HD 5450, which uses a 40 nm design. AMD has clocked the core speed at 650 MHz. The DDR3 RAM runs at a speed of 800 MHz on this particular model. It features 80(16x5) SPUs along with 8 TAUs and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have the exact same bandwidth, so theoretically they should perform exactly the same. (explain)
Texel RateThe GeForce 8600 GT 256MB DDR2 is quite a bit (more or less 66%) more effective at AF than the Radeon HD 5450. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce 8600 GT 256MB DDR2 is the winner, and very much so. (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 over the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units by the core 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 in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
