No, it's this:

00:02.0 VGA compatible controller: Intel Corporation Raptor Lake-P [Iris Xe 
Graphics]

The box is a 16-thread i5 with 32GB.

I notice though that the core temp is steady at 60C, so it looks as though 
it's running back-to-back NOPs, because any real load would have it near 90C 
and the fan running hard.

Oh, and a reboot makes no difference. Perhaps I should start recompiling 
things...
