Compare any two graphics cards:
GeForce 9800 GX2 vs GeForce GT 240 GDDR5
IntroThe GeForce 9800 GX2 uses a 65 nm design. nVidia has set the core frequency at 600 MHz. The GDDR3 memory is set to run at a frequency of 1000 MHz on this particular card. It features 128 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.Compare those specifications to the GeForce GT 240 GDDR5, which features core clock speeds of 550 MHz on the GPU, and 850 MHz on the 512 MB of GDDR5 RAM. It features 96 SPUs along with 32 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 9800 GX2 should perform quite a bit faster than the GeForce GT 240 GDDR5 overall. (explain)
Texel RateThe GeForce 9800 GX2 is quite a bit (more or less 336%) better at texture filtering than the GeForce GT 240 GDDR5. (explain)
Pixel RateThe GeForce 9800 GX2 should be a lot (about 336%) more effective at AA than the GeForce GT 240 GDDR5, and also should be capable of handling higher resolutions while still performing well. (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

Memory Bandwidth: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. 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 many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
