This test assess raw hashing power (SHA-512) for 1..N CPU cores, the cryptographic hash that IntegrityChecker Java uses.

Intel-based Macs have dedicated instruction support for fast hashing, and the Java Virtual Machine gives those instructions lots of love with native code support.

But on Apple Silicon there is no special instruction support.

JDK 21 brings a 4X speed improvement to SHA512 hashing so that M1/M2 chips are now roughly double the speed of Intel chips. Prior JDK versions were 1/4 the speed seen here.

Figures assume that the Mac Pro is not running in slow mode.

The 2023 Mac Pro M2 Ultra hashes at an astounding 29 GB/sec, faster than the fastest 8-blade 16-lane PCIe SSD can deliver (20-24 GB/sec).
