On RAM: This is their low end chip; there will likely be another chip within a year supporting more ram. Nevertheless, there are reports from programmers and video editors that suggest that the 16 GB on M1 go a lot further than 16 GB on Intel. No hard technical reasons on why that would be.
(Also, anecdotally, I don't understand why HN keeps saying 16GB of RAM isn't a lot. I just upgraded my home desktop to 16 GB, and only because I also upgraded my screen from 1080 to 1440, and videogames were dipping below 60fps. Sure, at work my desktop has much more RAM, but for a laptop? 16 GB seems fine.)
On GPU: There's been some speculation that the eGPU's don't work due to driver support, not hardware issues. Once again, I wouldn't be surprised if the higher end chips in 2021 have a dedicated GPU inside the Pro and Mini.
On real world workloads: See the above about anecdotes about programmers and video editors. I don't know if there's any great sources here besides reading twitter and trying to avoid biased fanboys.
I'm waiting for more of the languages and tools I use to become fully supported on the M1 before I bite the bullet, but I'm finding fewer and fewer reasons to be skeptical of the performance numbers...
- terminalcommand 6y agoI have heard that the difference comes from software. Apple endorses a reference counting garbage collector, whereas many windows programs (.NET programs for example) use a tracing garbage collector. In result, native macos (and ios) programs need less memory. As macOS is also built on the same memory discipline, it is more memory efficient.
