The difference is dual screens don't work on the M1 MBA because it physically only has two display controllers in the silicon, one of them wired to the internal panel, and the other muxed to the two TB ports. The M1 Pro has two external display controllers, and the M1 Max four. I can show you where they are on the die shots, and that it's not artificial crippling.
But what Intel is doing here is disabling existing silicon that exists and works.
- gambiting 5y agoSure, but as a customer that's irrelevant, right? You had a MacBook Air, used it with two displays, then you buy a new MacBook Air and bam, it doesn't work with two displays. The technical nitty gritty is not really relevant - at least the comment I was replying to sounded this way. That what the customer expects is more important than what is on the spec sheet? The fact that previous Intel CPU supported AVX-512, and the new one doesn't - so whether this fact is or isn't mentioned in the spec sheet is not important, because what the customer expects should be ultimately what decides what is "ok".
