Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs GeForce GTX 980M
IntroThe GeForce 8600 GT 512MB DDR2 has core speeds of 540 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 RAM. It features 32 SPUs as well as 16 TAUs and 8 ROPs.Compare those specs to the GeForce GTX 980M, which features a core clock frequency of 1038 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 256-bit memory bus, and makes use of a 28 nm design. It is comprised of 1536 SPUs, 96 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 980M should in theory be much better than the GeForce 8600 GT 512MB DDR2 in general. (explain)
Texel RateThe GeForce GTX 980M is a lot (about 1053%) more effective at AF than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateThe GeForce GTX 980M is a lot (more or less 1438%) more effective at FSAA than the GeForce 8600 GT 512MB DDR2, and capable of handling higher screen resolutions while still performing well. (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 transported over the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
