Compare any two graphics cards:
GeForce 8800 GTS (G80) 640MB vs GeForce 9800 GT 1GB
IntroThe GeForce 8800 GTS (G80) 640MB comes with a GPU core speed of 513 MHz, and the 640 MB of GDDR3 RAM is set to run at 792 MHz through a 320-bit bus. It also is made up of 96 Stream Processors, 48 Texture Address Units, and 20 ROPs.Compare those specs to the GeForce 9800 GT 1GB, which has core speeds of 600 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 RAM. It features 112 SPUs along with 56 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 8800 GTS (G80) 640MB should in theory be just a bit faster than the GeForce 9800 GT 1GB in general. (explain)
Texel RateThe GeForce 9800 GT 1GB is a lot (approximately 36%) faster with regards to AF than the GeForce 8800 GTS (G80) 640MB. (explain)
Pixel RateThe GeForce 8800 GTS (G80) 640MB will be just a bit (approximately 7%) better at anti-aliasing than the GeForce 9800 GT 1GB, and should be able to handle higher screen 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 maximum amount of data (in units of MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the 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 amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the 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 the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. 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 output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
