Since the advent of PC, Moore's Law has proven the progress of the semiconductor process, the CPU chip manufacturing process has gone through 10 microns, 6 microns, 3 microns... until the current 32 nm, 22 nm evolution, and the current mainstream of 14 nm, compared to the level of chip-level CPU evolution, the development of the hardware is not so obvious, PCB board shape is still not too much change, from ATX to Micro ATX, then Mini itx, motherboard size of the geometry did not happen a big change, but this can’t explain that the major motherboard manufacturers do not try to change, perhaps there has been developed to a bottleneck stage. In recent years, the development of PC is facing the problem of market saturation, due to technological progress, the quality of the product has a considerable guarantee, the variance of the change can not attract the user enough. Global equipment shipments in 2017 will drop by 3% ,and down 0.75% from last year's report, as forecasted by Gartn...
