Compare any two graphics cards:
GeForce 8600 GT 1GB DDR2 vs GeForce GTX 850M
IntroThe GeForce 8600 GT 1GB DDR2 uses a 80 nm design. nVidia has set the core speed at 540 MHz. The DDR2 memory works at a frequency of 400 MHz on this specific model. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.Compare those specs to the GeForce GTX 850M, which has clock speeds of 876 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 850M should in theory perform much faster than the GeForce 8600 GT 1GB DDR2 in general. (explain)
Texel RateThe GeForce GTX 850M will be quite a bit (approximately 306%) faster with regards to anisotropic filtering than the GeForce 8600 GT 1GB DDR2. (explain)
Pixel RateThe GeForce GTX 850M will be much (about 224%) faster with regards to full screen anti-aliasing than the GeForce 8600 GT 1GB DDR2, and should be able to handle higher screen resolutions more effectively. (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 maximum amount of information (in units of megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units by the core 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 per second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
