My immediate thought is that Sun beat both of these guys to market with the T1 20 years ago. Not exactly the same thing, but I wonder how close to the same idea they are; the line seems to have stopped with the M8, which is a 32c/256t part from 2017.

Epyc Naples was also 32c and also 2017. 4- and 8-way SMT wasn't something AMD or Intel ever bothered with, no, but IBM also did with the POWER line. It seems to help in some workloads, but probably isn't generally useful enough for volume solutions.
There is an absolutely huge difference between a 32c/256t part and a 128c/256t part. And Tera's MTA predated the T1 by quite a bit with a similar (and evidently doomed) architecture...
