Compare any two graphics cards:
GeForce 9800 GX2 vs GeForce GTX 750
IntroThe GeForce 9800 GX2 comes with a GPU core clock speed of 600 MHz, and the 512 MB of GDDR3 memory runs at 1000 MHz through a 256-bit bus. It also is made up of 128 SPUs, 64 TAUs, and 16 ROPs.Compare that to the GeForce GTX 750, which has a core clock frequency of 1020 MHz and a GDDR5 memory frequency of 1250 MHz. It also features a 128-bit bus, and makes use of a 28 nm design. It is made up of 512 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce 9800 GX2 will be 60% faster than the GeForce GTX 750 in general, due to its greater data rate. (explain)
Texel RateThe GeForce 9800 GX2 is a lot (more or less 135%) more effective at AF than the GeForce GTX 750. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce 9800 GX2 is a better choice, though not 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 max amount of data (measured in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
