Compare any two graphics cards:
GeForce 9800 GX2 vs GeForce GTX 275
IntroThe GeForce 9800 GX2 uses a 65 nm design. nVidia has set the core frequency at 600 MHz. The GDDR3 RAM works at a speed of 1000 MHz on this model. It features 128 SPUs as well as 64 Texture Address Units and 16 ROPs.Compare those specifications to the GeForce GTX 275, which features GPU core speed of 633 MHz, and 896 MB of GDDR3 RAM set to run at 1134 MHz through a 448-bit bus. It also is made up of 240 Stream Processors, 80 TAUs, and 28 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 9800 GX2 should theoretically be a bit faster than the GeForce GTX 275 overall. (explain)
Texel RateThe GeForce 9800 GX2 is much (approximately 52%) more effective at texture filtering than the GeForce GTX 275. (explain)
Pixel RateThe GeForce 9800 GX2 should be just a bit (more or less 8%) better at FSAA than the GeForce GTX 275, and also capable of handling higher resolutions better. (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 transported across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high 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 graphics card will be at handling 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 its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
