Compare any two graphics cards:
GeForce 9800 GX2 vs GeForce GTX 965M
IntroThe GeForce 9800 GX2 makes use of a 65 nm design. nVidia has clocked the core frequency at 600 MHz. The GDDR3 memory runs at a frequency of 1000 MHz on this particular model. It features 128 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.Compare those specifications to the GeForce GTX 965M, which uses a 28 nm design. nVidia has set the core frequency at 944 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this particular model. It features 1024 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 9800 GX2 should be 100% faster than the GeForce GTX 965M in general, due to its greater bandwidth. (explain)
Texel RateThe GeForce 9800 GX2 will be a lot (more or less 27%) better at texture filtering than the GeForce GTX 965M. (explain)
Pixel RateThe GeForce GTX 965M will be quite a bit (more or less 57%) better at AA than the GeForce 9800 GX2, and should be capable of handling 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

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
