I think embedded systems account for the vast majority of chip production, so any dynamics involving Intel/AMD would be very minor.

In units, perhaps, but not in $$, far from it.

Embedded chips are generally cheap. CPU’s sell for ~1,000x the price of most embedded chips. X00$ CPU vs X0c 32 bit microprocessors / microcontroller etc.

10c 32-bit microcontroller from Intel/AMD? Have I been buying the wrong chips? Care to share some links?

EDIT: commenter above edited their post, mentioned $.10 MCUs from Intel/AMD

I edited the comment for clarity, but never mentioned Intel or AMD.

All right, X0 c 32-bit microcontrollers from whom?

Cypress, Microchip, STM... Really, take your pick.

Inter generational gains leveled off 5-6 years ago.

I have an intel chip from 6 years ago and I still feel there is hardly any reason to upgrade. It still does everything I need it to do very well. I upgraded my gpu that was about 5 years old and I saw about 3x the performance.

The last few years have been mostly about performance per watt. I changed my notebook a couple of years ago, jumped from an i3 3200 to an i5 7200U. I got 80% better performance (on numerical code) at 15W, instead of 35W for the i3. Unfortunately manufacturers cheaped out on the battery, so I went from 6 cell to 3 cell, for about-ish the same battery life I had on my previous notebook.
