Compare any two graphics cards:
GeForce 8800 GTS (G80) 640MB vs GeForce GT 340
IntroThe GeForce 8800 GTS (G80) 640MB has a clock speed of 513 MHz and a GDDR3 memory speed of 792 MHz. It also uses a 320-bit memory bus, and uses a 90 nm design. It features 96 SPUs, 48 TAUs, and 20 Raster Operation Units.Compare all that to the GeForce GT 340, which has GPU core speed of 550 MHz, and 512 MB of GDDR5 RAM running at 850 MHz through a 128-bit bus. It also is comprised of 96 Stream Processors, 32 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 8800 GTS (G80) 640MB should perform a little bit faster than the GeForce GT 340 in general. (explain)
Texel RateThe GeForce 8800 GTS (G80) 640MB should be much (about 40%) better at anisotropic filtering than the GeForce GT 340. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce 8800 GTS (G80) 640MB is the winner, by far. (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 moved across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should 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 AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
