Compare any two graphics cards:
GeForce 8800 GTS (G80) 320MB vs GeForce 9800 GT 512MB
IntroThe GeForce 8800 GTS (G80) 320MB has core clock speeds of 513 MHz on the GPU, and 792 MHz on the 320 MB of GDDR3 memory. It features 96 SPUs as well as 48 TAUs and 20 Rasterization Operator Units.Compare all of that to the GeForce 9800 GT 512MB, which uses a 65/55 nm design. nVidia has set the core frequency at 600 MHz. The GDDR3 RAM is set to run at a speed of 900 MHz on this model. It features 112 SPUs as well as 56 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 8800 GTS (G80) 320MB will be 10% quicker than the GeForce 9800 GT 512MB overall, because of its higher data rate. (explain)
Texel RateThe GeForce 9800 GT 512MB is a lot (about 36%) more effective at AF than the GeForce 8800 GTS (G80) 320MB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce 8800 GTS (G80) 320MB 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 (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is 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 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
