Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs GeForce GTX 280
IntroThe GeForce 8600 GT 512MB DDR2 comes with a core clock speed of 540 MHz and a DDR2 memory frequency of 400 MHz. It also makes use of a 128-bit memory bus, and makes use of a 80 nm design. It is made up of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare those specs to the GeForce GTX 280, which has a core clock frequency of 602 MHz and a GDDR3 memory speed of 1107 MHz. It also features a 512-bit memory bus, and makes use of a 65 nm design. It is made up of 240 SPUs, 80 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 280 should theoretically be much faster than the GeForce 8600 GT 512MB DDR2 overall. (explain)
Texel RateThe GeForce GTX 280 should be quite a bit (more or less 457%) more effective at anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 280 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 maximum amount of data (counted in MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
