Compare any two graphics cards:
GeForce 9800 GX2 vs Radeon HD 6750 1GB
IntroThe GeForce 9800 GX2 has a GPU core clock speed of 600 MHz, and the 512 MB of GDDR3 memory 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 that to the Radeon HD 6750 1GB, which makes use of a 40 nm design. AMD has clocked the core frequency at 725 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this card. It features 720 SPUs along with 36 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce 9800 GX2 should in theory be quite a bit superior to the Radeon HD 6750 1GB in general. (explain)
Texel RateThe GeForce 9800 GX2 should be much (more or less 194%) faster with regards to anisotropic filtering than the Radeon HD 6750 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce 9800 GX2 is superior to the Radeon HD 6750 1GB, by a large margin. (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 largest amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write 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 card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
