They haven't suffered at least in the UAE. Judging by many of the posts on overclock.net, people are still hugging their 14900K PCs because "it offers the lowest possible RAM latency" and "fewest stutters" in a broad range of games (their justifications) and they bemoan that reviewers select "AMD leaning" game titles for benchmarking. They admit that there are degradation problems but they have taken steps in their BIOS to prevent that (the electrical settings etc. and what not).
I just haven't heard in normal conversations or seen anything in the local news media to suggest that Intel's reputation has been damaged. They seem to be doing OK, in the minds of people who don't really care about CPUs and tend to be more "laptop brand" loyal than CPU manufacturer loyal.
I think Intel suffered badly, but the there is some delay / inefficiency in "word of month" to spread.
Because, Intel has had the "media" in its pocket, through various forms of advertisement, "consulting", sponsorships, the news does not get out through those channels.
But if you want to look at leading edge toward mainstream (Mind Factory, Amazon, Newegg, Micro Center), Intel went from dominating to 50:50 to 1:10 or worse.
BTW, Micro Center customers have been slow to shift from Intel to AMD, but that is happening now too. When you start from overall processors -> all CPUs, there is an option to sort by "Most Popular". And currently, 8 out of top 10 are AMD CPUs.

The prospects for the future don't look too bright, as the the best of the new gen of processors is at #12
