Compare any two graphics cards:
GeForce 8600 GT 1GB GDDR3 vs GeForce 8800 GT 512MB
IntroThe GeForce 8600 GT 1GB GDDR3 features a GPU clock speed of 540 MHz, and the 1024 MB of GDDR3 memory is set to run at 700 MHz through a 128-bit bus. It also features 32 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.Compare those specs to the GeForce 8800 GT 512MB, which makes use of a 65 nm design. nVidia has set the core frequency at 600 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this particular model. It features 112 SPUs along with 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 8800 GT 512MB should theoretically be a lot faster than the GeForce 8600 GT 1GB GDDR3 overall. (explain)
Texel RateThe GeForce 8800 GT 512MB is quite a bit (approximately 289%) better at anisotropic filtering than the GeForce 8600 GT 1GB GDDR3. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce 8800 GT 512MB is superior to the GeForce 8600 GT 1GB 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 across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 max fill rate.
