The designers and architects behind Lunar Lake’s new Lion Cove P-cores made the decision to remove Hyper-Threading logic and focus on optimizing for single-threaded performance. Ori Lempel, Senior Principal Engineer in the P-core architecture team, explains why. For a more detailed overview of Lunar Lake, click or tap the link featured at the bottom of this video.

So Hyperthreading was a bad idea?
They wish. It reduces cost for them to make but increase the cost for buyers. IDK why did Intel from top dawg became miserable liars?
need triplethread & multithread mode support for top cpu only, for desktop and workstation cpu
I have a idea, hyperthread disabled by default, user can enable in bios for some multithread work when needed
Does that mean it'll run slower without hyperthreading?
Lunar Lake will dead on day 1. Your idea like chop off Lion legs then use the cat legs instead to competing with AMD and ARM skus. Lunar Lake fate also like Cannonlake on 10nm Era. And Meteor Lake on 7nm EUV Era.
I don't want to encounter any more scheduling issues. For example, when I am transcoding a video using Handbrake. When I set the power plan to High Performance in Windows settings, all CPUs indeed operate at full capacity, with CPU usage usually above 85%. However, occasionally, at specific times, it drops to below 20%. It's frustrating because I can't find the reason for this. Upon checking, I found that the power settings had defaulted back, even though the Control Panel shows it as High Performance. This uncontrollable situation is annoying. While it can be fixed, the fact that it happens inadvertently is irritating.
I don't care how many threads you have, whether you have hyper-threading, or how many cores—these things are irrelevant to me as a consumer. Even if you only have one core, if your single-core efficiency surpasses that of a competitor like the 9950X, I would consider you a godsend. And if you use 100 cores, as long as there are no scheduling issues, power consumption is acceptable, and the price is competitive compared to the competition, I'd be willing to buy. As a user, I don't care about the package you provide. What matters is its actual performance, the corresponding price, and power consumption. So I don't care if you have hyper-threading or why it was removed. If your supposed flagship with 8+16 cores outperforms the competitor's 24-thread multi-core performance while consuming less power and is reasonably priced compared to the competition, and most importantly, if it doesn't have known defects like scheduling issues or blue screens that used to be AMD's disadvantages but are now Intel's, do you feel regret and shame?
Thanks to Intel for this videos about the technology inside the processor 👏🏻
