Results —  aggregate hashing speed

The M3 Max CPU is a winner, offering a consistent 10% higher performance than M2 Ultra out to 15 CPU cores (dropping to 7% at 16 CPU cores).

CPU core parity: strikingly, the M1 Max matches the 24-core M23 Ultra right out to 16 cores! That’s impressive ! An M3 Ultra would be dual M3 Max chips (32 CPU cores). That will leave the M2 Ultra far behind (32 vs 24 cores).

For everyday workloads, nothing beats real tests, but this single test strongly suggests:

  • The 16-core M3 Max laptop match or slightly outperform the 24-core M2 Ultra Mac Pro with many (most for most users) workloads.
  • For relatively-rare fully scalable CPU-core-intensive workloads, M2 Ultra will take the lead.
  • M3 Ultra will leave the M2 Ultra far behind (dual M3 Max chips 32 CPU cores).

For most users, a 14" or 16" M3 Max laptop will outperform the 2023 Mac Pro M2 Ultra on many workloads. Not until we see a Mac Pro M3 Ultra will that equation change. The one advantage the Mac Pro has is up to 384GB memory But 128GB in the laptops serves virtually all users exceedingly well.

I put $9K into a Mac Pro only 6 months ago... it was the right decision given the situation, and a neat-and-clean transition over my laggard 2019 Mac Pro 28-core Intel. Still, a 32-core Mac Pro M3 Ultra would be a boon for my focus stacking and other CPU intensive jobs.

Results identical on 14-inch and 16-inch 2023 MacBook Pro M3 Max.
