Intel Hyperthreading… worth it?

Intel Hyperthreading… worth it?

In a recent post, I listed a benchmark using Cinebench R15 on a pair of Xeon Gold 6144 CPU’s.  In that post, I mentioned that hyperthreading was enabled.  How much of a difference did that make?

To recap, here’s the full 16 physical/32 logical benchmark:

And now, hyperthreading disabled:

And there we go.  Hyperthreading adds another 747 points, for an increase of nearly 28%.

Oddly, that goes in line with something I read before where hyperthreading can add up to a 25% increase in performance (on physical hardware).  Sadly I can’t remember where I read that, or when.
