I’m sure in the labs they already tested great chips. That doesn’t mean we’ll see them right away. They’ll release them as the market moves on.The only way Apple could justify switching to its own silicon is if their chip blows out of the water the best chips from Intel and AMD. Apple should play the best hand they have with this annoucnment and present a true beast. Anthing less than 50-75% performance and battery life increase compared to an equivalent Intel chip would be a dissapointment. If Apple cant beat i9 by a wide margin, the whole switching would make very little sense. Apple already has a more advanced production node at 5nm so how fast and efficient is their own architecture is the true mistery.
So, realistically, I think we’ll see low-end Macs getting slightly more powerful, and a lot more battery life, and high-end Macs to still be slightly better at performance. But I don’t get my hope up for a much more powerful Mac as of 2020 and 2021
