TurboCube Mac OS

Apple has been bundling its Mac computers with Intel processors for a while now, which means the chip-maker’s Turbo Boost technology can be found in supported Mac models. However, Apple gives you no real control over it, which essentially means you cannot turn it on or off at will. OS X does it all automatically.

I have a 2017 Macbook Pro with touch bar and i7-7920HQ @ 3.10 Ghz. I've noticed several issues in Windows 10 (build 1709) that relate to the CPU.

  1. Task manager shows base speed of 3.00 GHz instead of 3.10
  2. No matter the load, the CPU speed never goes above 3.0 GHz


I noticed in 2012 users were reporting a similar issue with turbo boost:

Using information from that thread, I checked and it appears the MSR multiplier is locked at 31. If I use Throttlestop I can set the MSR to 41 and the CPU then enters turbo boost with higher speeds.


This seems like bug that needs an EFI firmware fix. Does anyone have any other ideas?

Sparked by rumors of a performance-enhancing Pro Mode for the Mac, developer and podcaster Marco Arment is calling on Apple to introduce a Low Power Mode for Mac laptops. Such a feature has already been available for iOS since iOS 9, and Arment has found a way to implement something similar with the $9.95 Turbo Boost Switcher Pro, which prevents Intel’s Turbo Boost feature from automatically overclocking the processor for intensive tasks. (There’s also a free Turbo Boost Switcher that requires more manual interaction but would likely be sufficient for testing.)

What benefits does turning off Turbo Boost offer for MacBooks? Arment reports a 62% drop in power consumption and a significant decrease in temperatures on his 16-inch MacBook Pro. Anecdotally, he says that the fans do not spin up, and the MacBook Pro runs cool enough to keep on his lap. While he hasn’t performed battery life tests on the 16-inch MacBook Pro, he estimates 30–50% longer battery life on older models. Of course, those benefits come with performance trade-offs like lower Geekbench scores—46% lower in single-threaded tests and 29% lower in multi-threaded—and 59% longer Xcode builds.

But most laptop users would happily make those trade-offs while on the go. Unfortunately, Turbo Boost Switcher Pro depends on a kernel extension that won’t be supported in future versions of macOS. Hopefully, Apple will introduce a Low Power Mode in the next version of macOS that solves the problem without additional software.
