Compare any two graphics cards:
GeForce 9800 GX2 vs GeForce GT 340 1GB
IntroThe GeForce 9800 GX2 has a clock frequency of 600 MHz and a GDDR3 memory speed of 1000 MHz. It also makes use of a 256-bit bus, and makes use of a 65 nm design. It features 128 SPUs, 64 Texture Address Units, and 16 ROPs.Compare all of that to the GeForce GT 340 1GB, which uses a 40 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR5 RAM works at a frequency of 850 MHz on this card. It features 96 SPUs along with 32 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce 9800 GX2 should be much faster than the GeForce GT 340 1GB overall. (explain)
Texel RateThe GeForce 9800 GX2 will be quite a bit (approximately 336%) more effective at anisotropic filtering than the GeForce GT 340 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce 9800 GX2 is a better choice, 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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, 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 card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
