Company Apple Lossless Audio CODEC (ALAC), is preparing an interesting change for its Macs, it being possible thanks to the processors Intel Skylake who have implemented a technology called Speed shift, being able to increase the performance and autonomy of computers.
Specifically, technology Speed shift implemented in the new processors Intel Skylake allows the dynamic change of working frequencies up to 30 times faster than in the past because these fluctuations can be made by the processor and not by the operating system.
At the moment, the operating system of a computer dynamically changes the working frequency of a computer to reduce energy consumption, but if this task is done directly by the computer, everything is done much faster and energy is saved.
In the case of changing the operating state from an efficient one, which saves energy, to one that offers maximum performance, we are talking about a reduction to a third of the time required to carry out all the changes, Speed shift being able to seriously improve the performance of the calculators.
Specific jumps in frequency are reduced to around 1ms with Speed Shift's CPU control from 20-30 ms on OS control, and going from an efficient power state to maximum performance can be done in around 35 ms, compared to around 100 ms with the legacy implementation . As seen in the images below, neither technology can jump from low to high instantly, because to maintain data coherence through frequency/voltage changes there is an element of gradient as data is realigned.
Implementing support for this new processor technology Intel Skylake was discovered in OS X for one MacBook 9,1 which has not yet been launched, but which will probably reach the market in the summer together with models that have similar support.
Windows 10 currently does not have support for this technology, but it would offer it starting in November, so Apple could have exclusivity for it until then.
