In theory yes but that would be H, not S. The H also has a quad core die as well.
Which is rather nuts if you think about it, because it will beat pretty much all Intel desktop chips in terms of performance and power consumption.
Regarding RKL, I wasn’t able to find much on RKL, just a geekbench score, though I thought there was a 3DMark one, I couldn’t find it. The GB score looked pretty underwhelming.
EDIT: I don’t include AMD chips here, because anything Intel manages to push out will be against Zen 3.
