- Applejinx 6y agoThat's fair. I see that in software encoding to x264, in OBS (though admittedly the M1 is running under Rosetta still). The iMac Pro can reliably stream at 'slow' quality level, but the M1 can barely go above 'ultrafast' without choking. You've nailed it as far as the reason: if you can come up with a task that legitimately needs parallelism that heavy, that's where the Xeon comes into its own. Anything lighter, and the M1 starts to zip ahead.
- 1123581321 6y agoWhat type and size of compile, and what numbers do you see?
- spacedcowboy 6y agoGenerally something like Mail.app or Xcode.app or some internal frameworks that can get pretty huge. Not sure if I’m comfortable disclosing numbers, but the iMac Pro is a lot faster for me in that sort of situation.
