Compare any two graphics cards:
GeForce 8600 GT 256MB GDDR3 vs GeForce 8600 GTS
IntroThe GeForce 8600 GT 256MB GDDR3 features a core clock speed of 540 MHz and a GDDR3 memory speed of 700 MHz. It also uses a 128-bit bus, and makes use of a 80 nm design. It is made up of 32 SPUs, 16 Texture Address Units, and 8 ROPs.Compare all of that to the GeForce 8600 GTS, which features a clock frequency of 675 MHz and a GDDR3 memory frequency of 1000 MHz. It also features a 128-bit memory bus, and uses a 80 nm design. It is comprised of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce 8600 GTS will be 43% faster than the GeForce 8600 GT 256MB GDDR3 overall, because of its higher data rate. (explain)
Texel RateThe GeForce 8600 GTS should be much (more or less 25%) faster with regards to anisotropic filtering than the GeForce 8600 GT 256MB GDDR3. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce 8600 GTS is superior to the GeForce 8600 GT 256MB GDDR3, by a large margin. (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 data (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
