Compare any two graphics cards:
GeForce 9800 GT 1GB vs GeForce 9800 GX2
IntroThe GeForce 9800 GT 1GB uses a 65/55 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this card. It features 112 SPUs along with 56 TAUs and 16 ROPs.Compare that to the GeForce 9800 GX2, which features GPU clock speed of 600 MHz, and 512 MB of GDDR3 memory running at 1000 MHz through a 256-bit bus. It also is made up of 128 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce 9800 GX2 should be a lot faster than the GeForce 9800 GT 1GB overall. (explain)
Texel RateThe GeForce 9800 GX2 is much (approximately 129%) more effective at AF than the GeForce 9800 GT 1GB. (explain)
Pixel RateThe GeForce 9800 GX2 will be a lot (more or less 100%) faster with regards to full screen anti-aliasing than the GeForce 9800 GT 1GB, and also will be able to handle higher resolutions without losing too much performance. (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 MB per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs 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 lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
