Compare any two graphics cards:
GeForce 8600 GT 256MB GDDR3 vs GeForce GT 320
IntroThe GeForce 8600 GT 256MB GDDR3 features a GPU core speed of 540 MHz, and the 256 MB of GDDR3 RAM is set to run at 700 MHz through a 128-bit bus. It also is made up of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare that to the GeForce GT 320, which comes with GPU core speed of 540 MHz, and 1024 MB of GDDR3 memory set to run at 790 MHz through a 128-bit bus. It also is comprised of 72 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GT 320 should theoretically perform a small bit faster than the GeForce 8600 GT 256MB GDDR3 overall. (explain)
Texel RateThe GeForce GT 320 should be quite a bit (about 50%) faster with regards to AF than the GeForce 8600 GT 256MB GDDR3. (explain)
Pixel RateBoth cards have the exact same pixel fill rate, so theoretically they should be equally good at at anti-aliasing, and be capable of handling the same resolutions. (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 max amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's 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 amount of 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
