Compare any two graphics cards:
GeForce GTX 260 216SP 55 nm vs GeForce GTX 850M
IntroThe GeForce GTX 260 216SP 55 nm makes use of a 55 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 memory runs at a speed of 999 MHz on this specific model. It features 216 SPUs along with 72 TAUs and 28 Rasterization Operator Units.Compare those specs to the GeForce GTX 850M, which features clock speeds of 876 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 260 216SP 55 nm is 250% faster than the GeForce GTX 850M in general, because of its greater data rate. (explain)
Texel RateThe GeForce GTX 260 216SP 55 nm should be just a bit (more or less 18%) more effective at anisotropic filtering than the GeForce GTX 850M. (explain)
Pixel RateThe GeForce GTX 260 216SP 55 nm should be a bit (approximately 15%) more effective at full screen anti-aliasing than the GeForce GTX 850M, and should be able to handle 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 max amount of information (measured in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few 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.
