Compare any two graphics cards:
GeForce 8800 GTS (G80) 640MB vs GeForce 9800 GTX
IntroThe GeForce 8800 GTS (G80) 640MB uses a 90 nm design. nVidia has set the core speed at 513 MHz. The GDDR3 memory runs at a frequency of 792 MHz on this specific model. It features 96 SPUs along with 48 TAUs and 20 Rasterization Operator Units.Compare all of that to the GeForce 9800 GTX, which has core speeds of 675 MHz on the GPU, and 1100 MHz on the 512 MB of GDDR3 RAM. It features 128 SPUs as well as 64 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 9800 GTX should theoretically be a small bit faster than the GeForce 8800 GTS (G80) 640MB overall. (explain)
Texel RateThe GeForce 9800 GTX will be a lot (more or less 75%) more effective at AF than the GeForce 8800 GTS (G80) 640MB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce 9800 GTX is a better choice, 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: Bandwidth is the largest amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount 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 in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. 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 - the lower the bandwidth is, the lower the potential to reach the max fill rate.
