Hi Robert.
Don't you think, that, for example, SCSI controller plays the same role in
Intel world?
Thank you.

It also doesn't account for the fact that the Intel processor is doing its
own I/O, where that is almost completely off-loaded on the z9 to other
processors. In all, it really is an apples to oranges comparison, and
whatever conclusion you¹re looking for can be achieved.
