Compare any two graphics cards:
GeForce 9800 GX2 vs GeForce GTX 980M
IntroThe GeForce 9800 GX2 features a core clock frequency of 600 MHz and a GDDR3 memory speed of 1000 MHz. It also uses a 256-bit bus, and uses a 65 nm design. It features 128 SPUs, 64 TAUs, and 16 Raster Operation Units.Compare those specs to the GeForce GTX 980M, which makes use of a 28 nm design. nVidia has set the core speed at 1038 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this specific card. It features 1536 SPUs as well as 96 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have exactly the same bandwidth, so theoretically they should perform exactly the same. (explain)
Texel RateThe GeForce GTX 980M should be quite a bit (approximately 30%) more effective at texture filtering than the GeForce 9800 GX2. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 980M is superior to the GeForce 9800 GX2, 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

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock 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 applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
