Compare any two graphics cards:
GeForce 8800 GTS (G80) 640MB vs GeForce GT 340
IntroThe GeForce 8800 GTS (G80) 640MB uses a 90 nm design. nVidia has clocked the core frequency at 513 MHz. The GDDR3 memory runs at a speed of 792 MHz on this card. It features 96 SPUs as well as 48 TAUs and 20 Rasterization Operator Units.Compare all of that to the GeForce GT 340, which features a clock speed of 550 MHz and a GDDR5 memory speed of 850 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It features 96 SPUs, 32 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce 8800 GTS (G80) 640MB is 16% faster than the GeForce GT 340 in general, because of its greater bandwidth. (explain)
Texel RateThe GeForce 8800 GTS (G80) 640MB is a lot (approximately 40%) better at AF than the GeForce GT 340. (explain)
Pixel RateThe GeForce 8800 GTS (G80) 640MB is much (approximately 133%) faster with regards to anti-aliasing than the GeForce GT 340, and also able to handle higher screen resolutions without slowing down too much. (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 information (in units of megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it 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 anti-aliasing, High Dynamic Range and higher screen 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 by the core clock 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 applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
