Content Creation
Gaming
- 64-core GPU handles most macOS-native titles comfortably at 1440p
- Limited game library on macOS compared to Windows
- Rosetta 2 translation layer adds minor overhead for x86 games
- No support for external GPUs via Thunderbolt
- AAA titles running through CrossOver or Parallels may have reduced performance
- High single-core turbo (up to 4.6 GHz) helps smooth gameplay
- Lacks E-cores and hybrid optimizations of newer gaming CPUs
- Best suited as a workstation CPU that can also game, not the reverse
