Intel Currently Has No Plans For A Turbo Boost Max 3.0 Linux Driver

[ssokolow]

The recommended course of action is "learn to multithread", and has been since nearly a decade now.

That assumes your reason for buying newer CPUs isn't "I want to stick my PS2 discs into my PC and emulate because I'm tired of fighting a losing action against 'disc read error'".

For everything else, my PC is plenty fast and has been for years now.

Is there something stopping emulators from going multicore? http://www.unikgamer.com/forums/pcsx...ore-14000.html

Also emulators using Vulkan/dx12 can run better http://wccftech.com/dolphin-emulator...ce-boost-dx12/

Hmmm... Is this really true?

I have this CPU: http://ark.intel.com/products/71458
2.2 GHz base, 3.2 GHz with Turbo boost.

It seems when load is put on the CPU, it keeps all cores at about 2.9 GHz indefinitely and randomly puts other cores on the final bit of turbo boost, even though it's only the 2nd core that's 100% used by stress.

It just feels like Turbo Boost is not behaving very well for me...

Hi, I have a laptop with the 45W model of this same CPU, and it can stress 8 threads with full TB at 3.2GHz on all cores until it reaches it's higher temperature limit of 98C (or forever, when kept cool enough), but ONLY after changing a setting in the BIOS setup, otherwise TB can only do short boosts after a few threads are involved.

The model is Samsung NP880Z5E-X01UB (UB is the US model) from early 2013 and you can find it second hand for a pretty good price nowadays.

With stress -c 8 the CPU is locked to 2.9 GHz:

At least that works.

Temperature seems stable at around 76°C.

but ONLY after changing a setting in the BIOS setup, otherwise TB can only do short boosts after a few threads are involved.

As I said, there are zero settings other than on/off (I think it is there, but maybe even that is missing) in the BIOS.

Is there any way for the operating system to override those settings?

AFAIK no, it's a low-level hack done by BIOS, and not even an official feature (Intel does not want), you cannot do that from OS.

Thank you Tim Chen for the follow up, i appreciate the work and that intel developers follows up on development in threads here on phoronix.
