Compare any two graphics cards:
GeForce 8600 GT 1GB DDR2 vs GeForce 9800 GX2
IntroThe GeForce 8600 GT 1GB DDR2 has clock speeds of 540 MHz on the GPU, and 400 MHz on the 1024 MB of DDR2 RAM. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.Compare all that to the GeForce 9800 GX2, which has a clock speed 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 Texture Address Units, and 16 Raster Operation Units.

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 better than the GeForce 8600 GT 1GB DDR2 in general. (explain)
Texel RateThe GeForce 9800 GX2 will be quite a bit (about 789%) more effective at anisotropic filtering than the GeForce 8600 GT 1GB DDR2. (explain)
Pixel RateThe GeForce 9800 GX2 is much (about 344%) faster with regards to AA than the GeForce 8600 GT 1GB DDR2, and also will be capable of handling higher 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 maximum amount of data (in units of MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher 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 maximum amount of pixels that the graphics chip could possibly record to its local memory in a 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 - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
