It's a PR hit but certainly not a disaster. Everybody and their grandmother knew that a chip demoed to run at 5GHz is an overclocked hand picked engineering sample, Intel has been pulling the supercooled CPU stunt for decades.
At 250W thermal, the 4 die, 7nm Threadripper AMD announced will have similar cooling issues, a dead give away was that Lisa Su completely omitted Cinebench results - despite those being prominently featured before.
Bottom line is that AMD and Intel have roughly similar products and can easily cover for any performance differences using the large financial margins high end CPUs enjoy. The game then becomes a marketing one, who can keep more of that margin by convincing it's fan base they have decisively won the match.
