Compare any two graphics cards:
GeForce 8600 GS (OEM) vs GeForce GTX 870M
IntroThe GeForce 8600 GS (OEM) comes with core speeds of 540 MHz on the GPU, and 400 MHz on the 256 MB of DDR2 RAM. It features 32 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.Compare those specs to the GeForce GTX 870M, which has a clock frequency of 941 MHz and a GDDR5 memory frequency of 1000 MHz. It also features a 192-bit memory bus, and makes use of a 28 nm design. It features 1344 SPUs, 112 TAUs, and 24 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 870M should theoretically be much better than the GeForce 8600 GS (OEM) overall. (explain)
Texel RateThe GeForce GTX 870M will be a lot (approximately 1120%) more effective at anisotropic filtering than the GeForce 8600 GS (OEM). (explain)
Pixel RateThe GeForce GTX 870M is much (about 423%) better at FSAA than the GeForce 8600 GS (OEM), and will be capable of handling higher 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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
