Not sure I buy the apple needing low latency, sure SMT helps, but overall I wouldn't expect it to make a big difference.

Generally SPEC results are posted for the best performance configurations. So the 7313P (16 cores with high bandwidth per core) published results using 32 copies, which obviously uses SMT. But the 7763 (64 cores with low bandwidth per core) published only a 64 copies, presumably because SMT didn't help with performance. I also noticed that Epyc 7763 gets a base of 311 and the 7313p gets a base score of 181. So AMD gets less than a 2x performance with 4x the cores.
