Compare any two graphics cards:
GeForce 8500 GT vs GeForce 8600 GT 512MB DDR2
IntroThe GeForce 8500 GT comes with a GPU core speed of 450 MHz, and the 512 MB of DDR2 memory runs at 400 MHz through a 128-bit bus. It also is made up of 16 SPUs, 8 TAUs, and 4 Raster Operation Units.Compare those specifications to the GeForce 8600 GT 512MB DDR2, which has GPU core speed of 540 MHz, and 512 MB of DDR2 RAM running at 400 MHz through a 128-bit bus. It also features 32 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have the exact same memory bandwidth, so in theory they should perform the same. (explain)
Texel RateThe GeForce 8600 GT 512MB DDR2 should be a lot (about 140%) better at AF than the GeForce 8500 GT. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce 8600 GT 512MB DDR2 is superior to the GeForce 8500 GT, 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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated 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 output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
