My point was that the best use of hackintosh/VM tech is unrelated to "speed advantage". Apple has nothing that can touch a Threadripper for linearly scaled parallel workflows. The gap is so big that it might even overcome the arm/x86-64 emulation cost, though that wasn't what I was suggesting.

I've spent a lot of time on this. With QEMU, the performance gap is huge right now.
I have several ARM/QEMU virtual machines running on my AMD virtualization server, but the emulation overhead makes everything painfully slow, even when assigning 20+ cores to the VM. I picked up an 8GB Raspberry Pi because it's often faster to run a workload on the Raspberry Pi than even the many-core AMD emulated system.
The emulation overhead across architectures is huge with QEMU.
