Compare any two graphics cards:
GeForce 8800 GS vs GeForce GTX 850M
IntroThe GeForce 8800 GS features a clock frequency of 550 MHz and a GDDR3 memory speed of 800 MHz. It also features a 192-bit memory bus, and uses a 65 nm design. It is made up of 96 SPUs, 48 TAUs, and 12 ROPs.Compare all that to the GeForce GTX 850M, which comes with a core clock speed of 876 MHz and a DDR3 memory frequency of 1000 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 8800 GS, in theory, should be just a bit faster than the GeForce GTX 850M overall. (explain)
Texel RateThe GeForce GTX 850M is quite a bit (about 33%) better at AF than the GeForce 8800 GS. (explain)
Pixel RateThe GeForce GTX 850M will be much (about 112%) more effective at FSAA than the GeForce 8800 GS, and also should be able to handle higher screen resolutions better. (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 (counted in MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 are processed per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
