PC Perspective investigated whether Intel's new Speed Shift technology lives up to its name. Speed Shift is a new technology in the Skylake processor that aims to improve "snappiness" in areas where processor frequency needs to increase quickly as a result of user interaction or application need.
Microsoft added support for the feature in the most recent Windows 10 build 10586 update, and once installed you can not disable this feature. The technology is primarily intended for laptops and tablets, and PC Perspective reports it works very well and gives a noticeable increase in snappiness thanks to higher performance and reduced latency.
Without a doubt, Intel Speed Shift technology has improved the ability for the Intel + Windows platform to respond to user interaction dramatically. Though it will be most easily discernable with touch screen configurations, the same technology will apply to mouse based control.
