It's the heavily threaded workloads that will suffer the most. In a single threaded workload that single core can get as much power as it wants in both K and non-K. In a multi-threaded workload the cores are power limited, and K has a lot more power than non-K so the effect of power throttling is felt more on non-K.

Heavily threaded will suffer the most between the K & non-K, but not necessarily enough to drop below the "only" 16-core competition which was the comparison point here, not the K version. Especially since it's primarily the 8 P-cores that are really going to be impacted in such a scenario.

Hence why I specified "lightly threaded" not "single threaded" workloads. There's a whole huge market of workloads that sit at around 4-8 threads. They're called "video games" and it's what Intel has been bragging about being the best at for a while. The new crop of non-K's look prime to suffer the most in this workload relative to AMD's non-X competition.

On the contrary, the other article at the top of Anandtech right now shows that the K-series CPUs don't benefit from higher power levels in games. As far as games are concerned they might as well be 95W CPUs.

Anandtech sadly only tested 2 games in a fairly narrow set of parameters. If you look at 13900K reviews, such as this one by techpowerup: https://www.techpowerup.com/review/intel-core-i9-13900k/22.h... you'll see gaming loads where the 13900K uses well past 120w. Civ 6, for example, sits at nearly 190w.

But also again remember the 13600 non-K has much less L2 than the 13600k. It's not just a power/turbo restriction.

But we'll see for sure when the 13th gen non-K reviews happen. That Intel didn't sample these to reviewers isn't a great sign, though.
