No one on the Radiance “build/dev team” has or has immediate plans to purchase an M1 Mac, so we haven’t any experience running Radiance on the new hardware yet. In theory, binaries built for Intel will “just work” under the translation layer called Rosetta, but I’m old and grouchy and skeptical. THis is a rather good summary of the sitch:
“…power users should take note: The ARM-based Apple M1 is supposed to run legacy x86 software using Rosetta, which could cause adverse effects on performance when running x86 applications. Fortunately, due to its speed, the M1 will still outperform older Intel chips in most scenarios, even with legacy x86 apps. Also, some teething problems are to be expected, as exotic tools and applications might not run out of the box, or they may incur a performance penalty.” (https://www.toptal.com/apple/apple-m1-processor-compatibility-overview)
So it’s the same old same old. The new ARM chips will be awesome if you are all in on Apple and the most obvious applications. The rest of us will endure some degree of brain damage. As much as I’d like to get an M1 Mac and start exploring the new performance as well as start sorting out and benchmarking Radiance under the new hardware, I still like (need) to be able to run Windows VMs on my Mac too, and I think that Windows virtualized on top of x86 on top of Rosetta is going to suck for a while. I dunno, though. I’m glad you brought this up and I’m interested to hear what others out there are thinking in terms of this.
