Apparently the key to getting performance out of the Ampere Altra is … to just not use Windows? And have a very parallel workload. Yes, a single Altra core is half as fast as a single M1 Ultra core. But it really depends on your use case and other factors (e.g. power efficiency) which one is preferable.
