Compare any two graphics cards:
GeForce 9800 GX2 vs GeForce GTX 280
IntroThe GeForce 9800 GX2 comes with a GPU core speed of 600 MHz, and the 512 MB of GDDR3 RAM is set to run at 1000 MHz through a 256-bit bus. It also features 128 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.Compare those specs to the GeForce GTX 280, which features core speeds of 602 MHz on the GPU, and 1107 MHz on the 1024 MB of GDDR3 RAM. It features 240 SPUs along with 80 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 280 should in theory be a small bit better than the GeForce 9800 GX2 in general. (explain)
Texel RateThe GeForce 9800 GX2 will be quite a bit (approximately 59%) faster with regards to anisotropic filtering than the GeForce GTX 280. (explain)
Pixel RateThe GeForce GTX 280 is a bit (approximately 0%) more effective at FSAA than the GeForce 9800 GX2, and also should be capable of handling higher screen resolutions more effectively. (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 largest amount of information (in units of megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If 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 higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, 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 the video card could possibly record to the 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 the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
