    Those „40 %“ for Macs corresponds to disabled HT, too. ("Hyperthreading improves performance for certain workloads by 30 % to 40 %" see chapter 7)

    Indeed, the newest version of Mojave (10.14.5) reports whether or not Hyper-Threading is enabled.

    Hyper-Threading Technology: Enabled

    The only hyperthreading I have around is in notebooks. Surface Book (6600U), ASUS G750JY (4860HQ) and my ancient ASUS G73JH (920XM). I greatly look forward to seeing what Windows 10 does to them. I imagine the Surface Book will get more firmware updates, though I wonder how much longer MS will keep that up.

    I can't say I've noticed anything sluggish about the old 920XM with up-to-date Win7 or Win10 at this point.

    I've the 7980XE . Maybe no HT would be a slight performance improvement in the majority of cases for me.
