Compare any two graphics cards:
GeForce 8800 GTS (G80) 640MB vs GeForce 8800 GTS (G92)
IntroThe GeForce 8800 GTS (G80) 640MB features a core clock frequency of 513 MHz and a GDDR3 memory frequency of 792 MHz. It also makes use of a 320-bit memory bus, and makes use of a 90 nm design. It features 96 SPUs, 48 TAUs, and 20 ROPs.Compare those specs to the GeForce 8800 GTS (G92), which has GPU core speed of 650 MHz, and 512 MB of GDDR3 RAM running at 970 MHz through a 256-bit bus. It also features 128 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce 8800 GTS (G80) 640MB should in theory be just a bit better than the GeForce 8800 GTS (G92) overall. (explain)
Texel RateThe GeForce 8800 GTS (G92) will be much (more or less 69%) more effective at AF than the GeForce 8800 GTS (G80) 640MB. (explain)
Pixel RateThe GeForce 8800 GTS (G92) should be a little bit (about 1%) better at anti-aliasing than the GeForce 8800 GTS (G80) 640MB, and also capable of handling higher resolutions without losing too much performance. (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 information (in units of MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated 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 many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
