Compare any two graphics cards:
GeForce 9800 GX2 vs Radeon HD 3650 256MB
IntroThe GeForce 9800 GX2 has a clock frequency of 600 MHz and a GDDR3 memory frequency of 1000 MHz. It also uses a 256-bit bus, and makes use of a 65 nm design. It is comprised of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.Compare those specifications to the Radeon HD 3650 256MB, which has core speeds of 725 MHz on the GPU, and 800 MHz on the 256 MB of DDR2 memory. It features 120(24x5) SPUs along with 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 9800 GX2, in theory, should perform a lot faster than the Radeon HD 3650 256MB overall. (explain)
Texel RateThe GeForce 9800 GX2 is quite a bit (more or less 1224%) faster with regards to texture filtering than the Radeon HD 3650 256MB. (explain)
Pixel RateThe GeForce 9800 GX2 will be much (more or less 562%) more effective at anti-aliasing than the Radeon HD 3650 256MB, and should be able to handle higher resolutions without slowing down too much. (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 maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
