Compare any two graphics cards:
GeForce 8600 GT 256MB DDR2 vs GeForce GTX 980M
IntroThe GeForce 8600 GT 256MB DDR2 makes use of a 80 nm design. nVidia has clocked the core frequency at 540 MHz. The DDR2 RAM works at a speed of 400 MHz on this particular model. It features 32 SPUs as well as 16 TAUs and 8 ROPs.Compare those specs to the GeForce GTX 980M, which makes use of a 28 nm design. nVidia has clocked the core frequency at 1038 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this model. It features 1536 SPUs along with 96 TAUs and 64 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 980M should in theory perform quite a bit faster than the GeForce 8600 GT 256MB DDR2 in general. (explain)
Texel RateThe GeForce GTX 980M is quite a bit (about 1053%) more effective at AF than the GeForce 8600 GT 256MB DDR2. (explain)
Pixel RateThe GeForce GTX 980M is much (about 1438%) better at AA than the GeForce 8600 GT 256MB DDR2, and will 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output 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 ability to reach the maximum fill rate.
