Compare any two graphics cards:
GeForce 8600 GT 1GB GDDR3 vs GeForce 8800 GT 512MB
IntroThe GeForce 8600 GT 1GB GDDR3 comes with a clock speed of 540 MHz and a GDDR3 memory frequency of 700 MHz. It also uses a 128-bit bus, and uses a 80 nm design. It is comprised of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare those specs to the GeForce 8800 GT 512MB, which has a clock frequency of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 256-bit bus, and makes use of a 65 nm design. It is made up of 112 SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce 8800 GT 512MB should be a lot faster than the GeForce 8600 GT 1GB GDDR3 overall. (explain)
Texel RateThe GeForce 8800 GT 512MB is a lot (approximately 289%) more effective at anisotropic filtering than the GeForce 8600 GT 1GB GDDR3. (explain)
Pixel RateThe GeForce 8800 GT 512MB should be quite a bit (more or less 122%) more effective at AA than the GeForce 8600 GT 1GB GDDR3, and should be capable of handling higher screen resolutions while still performing well. (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 max amount of data (measured in megabytes per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units 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 most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
