Wendell From Level1techs and I have just finished testing and discovered that by enabling Message Signaled Interrupts on the Nvidia graphics card, the Combined Score disparity to the Physics score (Physics + Graphics load together - this is synthetic but it is doing similar things to games that put a reasonable load on the CPU) https://level1techs.com/article/fastest-ryzen-1800x-system-world-2017-03-20

I do not know if Radeon cards are using MSI by default or not. I seem to think that they do, however, If not, you may also see some benefit. You can check if you check the IRQ of your graphics card in device manager. If it is a +positive number then MSI is not enabled
We have not had a chance to see if the SMT on/off behaviour has been improved or not, but i suspect that if it does not resolve the problem, it will help alleviate it.
Aah I forgot about this, did it a while ago due to high DPC Latencies for a nVidia card, it was sharing IRQ's with a USB controller and my LAN on WIndows. MSI is enabled by default on Linux for the nVidia driver, get about 20FPS more with Dota 2 on Linux natively. After the Win MSI fix, things improved a bit.
Good job at LevelOneTechs, congrats. Now aim to knock the 6950K off of first place on TimeSpy.
The Radeon cards as far as I know has MSI enabled by default.
Here is a longer slightly older guide to MSI from Guru3D for anyone interested.http://forums.guru3d.com/showthread.php?t=378044
