Compare any two graphics cards:
GeForce 9800 GX2 vs Radeon HD 4730
IntroThe GeForce 9800 GX2 has a clock frequency of 600 MHz and a GDDR3 memory speed of 1000 MHz. It also makes use of a 256-bit bus, and uses a 65 nm design. It features 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.Compare those specs to the Radeon HD 4730, which features GPU core speed of 700 MHz, and 512 MB of GDDR5 memory running at 900 MHz through a 128-bit bus. It also is comprised of 640(128x5) Stream Processors, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce 9800 GX2 should theoretically be much superior to the Radeon HD 4730 in general. (explain)
Texel RateThe GeForce 9800 GX2 is a lot (approximately 243%) more effective at texture filtering than the Radeon HD 4730. (explain)
Pixel RateThe GeForce 9800 GX2 should be much (about 243%) faster with regards to FSAA than the Radeon HD 4730, and also able to handle higher screen resolutions while still performing well. (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 MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 processed in one 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 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 in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
