Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs GeForce 8800 Ultra
IntroThe GeForce 8600 GT 512MB DDR2 makes use of a 80 nm design. nVidia has clocked the core frequency at 540 MHz. The DDR2 RAM runs at a speed of 400 MHz on this specific card. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.Compare those specs to the GeForce 8800 Ultra, which features a core clock frequency of 612 MHz and a GDDR3 memory frequency of 1080 MHz. It also makes use of a 384-bit bus, and makes use of a 90 nm design. It features 128 SPUs, 64 TAUs, and 24 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce 8800 Ultra should in theory be quite a bit better than the GeForce 8600 GT 512MB DDR2 overall. (explain)
Texel RateThe GeForce 8800 Ultra should be much (more or less 353%) faster with regards to anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce 8800 Ultra is a better choice, by far. (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 (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock 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 applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
