Heat, and overheating is the enemy. My friend's MacBook Pro 2020 16" i7 gets so freaking hot and I think today the GPU might have given out. As a former tech, it made me wonder if these Apple Silicon Macs are going to show more resilience given the fact that they run so much cooler. Its too early to have too much data but its a seriously interesting question.
Far too early to tell.
In my opinion Intel reliability issues and them running so hot has more to do with shoddy manufacturing processes and poor design. I'm not trying to cast shade, but I can run my Xbox Series X with all the bells and whistles turned on, and you'll never hear the fan.
While on my sold a year or two ago MacBook Pro 16, core i7 sounded like it was trying to take off by just joining Microsoft Teams.
My opinion is Intel got sloppy and arrogant so they made bad choices. It's not the first time it's happened to them either. Remember the Pentium IV? They literally based all chips we have today off of the Pentium III due to the same decisions.
They've also been I think 5 years behind on their nm process to the point where they are just marking out 10nm and just saying "Intel 7" to look like it's the same as 7nm. It's shameful.
In terms of resilience long term, it's important to take note of the fact that while Apple has been making their own Mac chips for 2 years, they've been building chips of all sizes for I think 12 years. The worst constraints on workloads for testing how long something will last isn't the MacBook Air in my opinion. It's the iPhone and iPad. Much more tightly constrained cooling, and toddlers and teens exhausting them wanting to play games.
Again, this is just an opinion. Who knows, maybe my MacBook Pro 16 M1 Max will catch on fire on my lap. But I think I've heard the fan turn on MAYBE once?
