The first ARM chips were blazingly fast and made their competitors performance look anaemic - they have been around since the mid-1980s. The real difference is they went the low-power route while retaining as much performance as possible, rather than depending on desktop power supplies and industrial cooling.

One of the reasons this new chip is so performant is the "headroom" that this approach has given them.

I wish I understood better why Acorn Archimedes did not do better in the market. It looked like they had many great computer models.

Easy, IBM PC clones happened.

Apple are the survivors of the vertical integrated home computers, and they only managed to survive by reverse acquisition of NeXT, and diversifying outside of the desktop market.
