So much snappier is Windows 10 with ‘Speedshift’


Cooperation between the CPU and cheese is not quick enough.

When milliseconds count
By how much load is on the PC, lower clock speed, or the opposite: screwed up to Turbo speed when you need all the power you can get, for example in gaming or video editing.
The problem is that communication between OS and CPU, when the rate will go up or down, going too slow. It takes namely between 20 to 30 milliseconds.

Intel -CPUs takes control
They they have done with Skylake, their latest CPU series, is to implement something they have baptized “Speed Shift.” The technology ensures that the CPU and not the OS, manages its own speed.

This allows you to change the clock frequency within one millisecond. Going from Power Saving mode to performance takes only 35 milliseconds with ‘Speedshift’.

– Now max frequency of 35 milliseconds, said Intel.
So much faster it gets
Sweclockers tested with a Dell XPS 13 with Skylake-CPU Core i7-6600U (2.6GHz – Turbo 3.4 GHz. Min. Clock frequency 400 MHz).
In PCMark Home performance is 2.8 percent better. The best specific results obtained in WebXPRT 2015 (19.3 percent better performance) and WebXPRT 2013 (25.8 per cent better performance).


Test now
Support for the technology is not in place in the latest stable Windows 10 version, but you are running Windows 10-test version 10586 which launched Thursday this week, you can test already now if you have a Skylake-CPU.
