Compare any two graphics cards:
GeForce 9800 GX2 vs GeForce GT 240 GDDR5 1GB
IntroThe GeForce 9800 GX2 has a GPU core clock speed of 600 MHz, and the 512 MB of GDDR3 RAM runs at 1000 MHz through a 256-bit bus. It also features 128 Stream Processors, 64 Texture Address Units, and 16 ROPs.Compare those specifications to the GeForce GT 240 GDDR5 1GB, which makes use of a 40 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR5 RAM is set to run at a frequency of 850 MHz on this specific card. It features 96 SPUs along with 32 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 9800 GX2 should perform much faster than the GeForce GT 240 GDDR5 1GB overall. (explain)
Texel RateThe GeForce 9800 GX2 should be quite a bit (approximately 336%) more effective at texture filtering than the GeForce GT 240 GDDR5 1GB. (explain)
Pixel RateIf using high levels of AA 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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant 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.
