The upcoming Rocket Lake desktop CPUs can reach 5.3 GHz boost clocks and Intel hopes to reclaim the single-core crown, but it looks like AMD is ready to announce a countermove that could essentially render the whole Rocket Lake launch pointless.

This might just be binning, my 5900x boosts to at least 5ghz on 8/12 cores. 4 hit 5.1. And 2 hit 5.15.
While this is a positive development, the fact that more of the new generation of Ryzen chips don't come with stock fans means they're already running hotter, and this shorten's a chips lifespan. Ideally, a processor should never go above 50 degrees C in order to last. When they can go over 5 GHz base clock, not boost clock, at that temperature, then I'll be more excited.
Well, got all my CPU's overclocked and running in the 80/90c for years. Never got a sign of degradation.

Coming without a stock HSF likely means they're running *cooler*, because fewer end-users will be running high-end chips with inadequate cooling.
You'd struggle to find a modern CPU that stays under 50 degrees at load on the hottest core even with water-cooling, but it's okay, because you're completely wrong about the temperatures at which chips start to become damaged.
You'll be waiting until we've moved away from silicon to see multi-core chips with 5Ghz base clocks that run cooler than 50 degrees C on air, so please don't hold your breath.
