I love a good nerdy deep dive, even on subjects far from my specialties. Enjoyed the read, keep them coming!

What happened to the 1977-1993 run with the 6502? It was the real first era and the longest.

Intel 8088 - "8/16-bit microprocessor — 8-bit registers with a 16-bit data bus"

I think you have this backwards. The 8088 had 16 bit registers with an 8 bit data bus.

I think, the production techniques are mostly underestimated.

Intel had and still have problems with the Tick-Tock-Cycle which delayed alot of their products.

AMD with its Ryzen/Epic series had success by using external vendors like TSMC and distribute the different parts over different production processes. With a improved design and more advanced production technique they were able to make a better processor.

AMD delivers more efficient and powerful mobile processors than Intel today but these processors aren't very common because of the lack of production capacities. For AMD it's business decision. They could earn more money with server chips than with consumer hardware. Intel the same: They could use a more advance process but they can't deliver the amount of requested processors for a good price for the consumer market.

With the success of the iPhone Apple was able to align the chip designs with the most advanced production techniques from different vendors like TSMC. Today TSMC is the only company with a 3nm process and Apple simple bought the whole production capacity. With the gigantic M3 chips they require a lot of capacities. But apple has the favour of niche market in the notebook segement so it isn't a big problem for them. They can simple increase the prices to regulate the market or prioritize thier cash cow (iPhone/iPad) to earn more money. On the other site Apple can block other chip vendors from the most advanced production sites.

it seems not mentioning AMD at the end as another factor in Intels decline is maybe oversimplifying; and in the other direction not mentioning SUN Sparc, DEC Alpha, HP PA RISC, MIPS, and IBM power in the transition to PowerPC is also a miss as these had an important part to play as to why Apple did not transition to Intel at that specific moment in time instead of ten years later.

and lastly another important point about the Apple/Acorn relationship is that Apples very survival between 1996 and 1999 was due to the shear volume of ARM stock apple owned and was able to sell to shore up its failing business giving it the necessary breathing room for R&D to redevelop next into rhapsody and into OSx as well as create the G3 iMac, until it got the $500million investment from microsoft which enables the full transition to OS X.

(obviously this is outside the scope of this article, but an interesting footnote nonetheless).

overall a great timeline piece really enjoyed your writing. thank you

Not deep enough dive into cpus and bit too Apple fan scent on it.
