I think that's "lots of people" meaning 10K or maybe 100K people. But the installed
base of desktops/laptops is hundreds of millions (the vast majority of whom are doing
either no video transcoding, or video transcoding using the pretty-good very-fast
hardware transcode engine).

Gaming is a subset of the total market; out of that subset, gaming rigs which aren't
limited by a low/midrange GPU are a smaller subset; and out of that smaller subset
you're picking those which happen to be running the few gaming engines which show
a useful speedup on 4C/8T over 4C/4T.

Web browsing seems to stress a single core pretty darn often. Pages don't render
instantly.

I don't think I'm misrepresenting anything. The vast majority of people with a 4C
are getting no benefit at all from SMT.
