Compare any two graphics cards:
GeForce 9800 GX2 vs Radeon HD 4730
IntroThe GeForce 9800 GX2 uses a 65 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 RAM works at a speed of 1000 MHz on this specific card. It features 128 SPUs along with 64 TAUs and 16 Rasterization Operator Units.Compare those specs to the Radeon HD 4730, which features GPU core speed of 700 MHz, and 512 MB of GDDR5 RAM running at 900 MHz through a 128-bit bus. It also features 640(128x5) Stream Processors, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 9800 GX2 should be a lot faster than the Radeon HD 4730 overall. (explain)
Texel RateThe GeForce 9800 GX2 is a lot (approximately 243%) faster with regards to texture filtering than the Radeon HD 4730. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce 9800 GX2 is the winner, and very much so. (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 max amount of data (measured in megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total 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 processed in a second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
