Compare any two graphics cards:
GeForce 8600 GT 1GB DDR2 vs GeForce GTX 980M
IntroThe GeForce 8600 GT 1GB DDR2 uses a 80 nm design. nVidia has set the core frequency at 540 MHz. The DDR2 RAM works at a speed of 400 MHz on this particular card. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.Compare all of that to the GeForce GTX 980M, which features a GPU core clock speed of 1038 MHz, and 4096 MB of GDDR5 memory set to run at 1000 MHz through a 256-bit bus. It also is made up of 1536 SPUs, 96 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 980M, in theory, should be much faster than the GeForce 8600 GT 1GB DDR2 in general. (explain)
Texel RateThe GeForce GTX 980M will be much (more or less 1053%) faster with regards to anisotropic filtering than the GeForce 8600 GT 1GB DDR2. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 980M is the winner, by far. (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 data (measured in megabytes per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once 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 higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
