Compare any two graphics cards:
GeForce 8800 GTS (G80) 640MB vs GeForce 8800 GTS (G92)
IntroThe GeForce 8800 GTS (G80) 640MB uses a 90 nm design. nVidia has set the core frequency at 513 MHz. The GDDR3 RAM is set to run at a speed of 792 MHz on this model. It features 96 SPUs as well as 48 Texture Address Units and 20 Rasterization Operator Units.Compare those specs to the GeForce 8800 GTS (G92), which makes use of a 65 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR3 RAM is set to run at a speed of 970 MHz on this specific model. It features 128 SPUs along with 64 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce 8800 GTS (G80) 640MB should in theory be a small bit better than the GeForce 8800 GTS (G92) overall. (explain)
Texel RateThe GeForce 8800 GTS (G92) will be quite a bit (more or less 69%) faster with regards to texture filtering than the GeForce 8800 GTS (G80) 640MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce 8800 GTS (G92) is the winner, but only just. (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 MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its 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 the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
