MPG tested the Apple 16.2" MacBook Pro with M2 Max Chip Z1740017Z, maxed-out excepting 4TB SSD.

About

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. UPDATE: erroneous assumption; Java 21 quadruples the hashing speed and it is now twice as fast as on Intel.

Results

Intel Macs do great, blowing away Apple Silicon.

UPDATE, June 2023: JDK 21 brings a 4X speed improvement to SHA512 hashing so that M1/M2 chips are now roughly double the speed of Intel chips.

The 2022 Macbook Pro M2 Max is takes 6 CPU cores to beat a wheezing 6-year-old 2015 MacBook Pro 4-core. That’s because Apple Silicon M1/M2 chips lack special CPU instructions for hashing.

The main thing to notice here is that the M2 Max chip delivers a barely noticeable 7% performance improvement over the M1 Max chip through 8 CPU cores (blue line vs black line). Both chips have 8 performance cores, the only difference being 4 vs 2 efficiency cores. We can therefore conclude that the raw computing power of the M2 Max CPU cores is barely noticeable vs the M1 Max. However, for the (rare) job that can use all the cores, hashing throughput is 23% greater on the M2 Max from that 7% along with the two additional efficiency cores.
