I'm hopeful that AMD will be able to press this new design into better performance than Intel can manage with their current technology at this price point.
Your optimism is cute, but unwarranted. AMD won't really be a threat until they can easily beat Intel at every performance level, price be damned.
Intel has no problem dropping prices to match the price/performance of anything AMD does. Inel is able to demand the prices they currently do because of AMD's decade-long streak of incompetence. Intel knows they can charge more because AMD isn't a threat.
If you want to know what Intel does consider a threat, you have to look at the ARM architecture (and ecosystem). Granted, ARM isn't a single company, but that's part of Intel's problem: Competing with ARM is fighting a Hydra - one company's failure doesn't really affect the ecosystem much, and the combined might of all of the ARM licensees ensures its viability.
ARM has almost perfect dominance for everything mobile and embedded - a market Intel has been trying desperately to enter, with zero success.
