What is the purpose of the Intel Turbo Boost Technology Driver?

It doesn't seem to be necessary for Turbo Boost to work properly, so what does it do?

  • Is it called "Intel Turbo Boost Technology Driver" or the "Intel(R) Turbo Boost Technology Monitor 2.0"? – William Hilsum Mar 25 '12 at 21:05
  • @WilliamHilsum: [**Driver**](http://esupport.sony.com/US/perl/swu-download.pl?mdl=VPCCW27FXB&upd_id=5284&os_group_id=6) – user541686 Mar 25 '12 at 21:18
  • Newer I series processors do not need the TB driver, its built into the processor now. – Moab Mar 25 '12 at 23:21
  • @Moab: Huh... which processors does that series include? (By "I series" do you mean the i3/i5/i7 series, or just a subset of them?) – user541686 Mar 26 '12 at 02:37
  • Second Gen I series, i7 for sure. I see lots of complaints on second gen when trying to install the TB driver, it won't install because it does not need one, see post by Joe G...http://communities.intel.com/thread/11604 – Moab Mar 26 '12 at 20:30

    @Moab: Hmmmmm okay... though it *does* install; it's just not needed apparently, that's all. – user541686 Mar 27 '12 at 05:04
  • Having this enabled is causing high fan usage when the PC is idle. When I log in, the fan slows and is quiet again. Weird. Since it doesn't need a driver installed any more I guess it's working as intended but don't really know. I'm just going to disable it in BIOS. – wunth Dec 12 '19 at 21:06

The purpose of the Intel Turbo Boost Technology Driver is described on the FAQ page of the driver:

What is Intel® Turbo Boost Max Technology 3.0 and how does it work?

Intel® Turbo Boost Max Technology 3.0 uses a driver coupled with information stored in the CPU to identify and direct workloads to the fastest core on the die first. The driver also allows for custom configuration via a whitelist that enables end users to set priority to preferred applications. The driver MUST be present on the system and configured correctly, as current operating systems cannot effectively route workloads to ordered cores.
