Not a lot of Apples:Apples benchmarks to compare

i9-13900K Passmark/CPU-Single 4,833 (about 9% increase)
i9-12900k Passmark/CPU-Single 4,412

Ryzen 9 7950 Geekbench-Single 2,217 (about 23% increase over 5950, 11% of 12900 )
Ryzen 9 5950 Geekbench-Single 1,759
i9-12900kf Geekbench-Single 1,990

It looks like we are going to have a horse race

In all fairness to Intel, a single core (or let's call it "low threaded") workload will never use the whole 240W. It'll hover around 70W, maybe 80W. Apple can't break the laws of physics, no matter how badly they want you to believe they use pixie dust for their stuff.

Raptor shows its teeth: Core i9-13900K tops PassMark's single-thread CPU performance rankings.

Intel's Core i9-13900K Leads Single-Thread Performance Rankings : Read more
The CPU scores 4,883 points in PassMark's single-thread performance benchmark, which is 471 points higher than Intel's Core i9-12900KS.
That should be 421 points, 4,883-4412.

It always depends on what you run, some things use more power than other, I also doubt that a single core could reach that high but I don't think it's impossible either.
 
What modern games or s/w benefits heavily on single core performance?
All the games and s/w I am running uses multiple cores, as I can clearly see on my secondary monitor, were I have Core Temp gadget and FPS Monitor (FPS counter on game screen) widgets to keep an eye on my CPU and my GPU (Asus AMD RX 6900 XT).
My primary monitor is a 27" 2560x1440 @165 Hz. I have limit it to 120 Hz so that I can try to maximize quality and as quiet as possible (low temp) gaming.

I would love to have an even heftier 16 core CPU, such as Ryzen 9 7950X, but the price tag for a new mobo, CPU, DDR 5 memory etc would make it hard on this side of the new year...

For example Assassins Creed Odyssey can use up to 12 cores and same goes for many other games, some can use all avaible cores.
This shows right now how Ghost Recon Breakpoint uses 8 CPU cores as well GPU load, GPU memory load and temp etc. on ultra settings - and very quiet gaming experience.

That's just going from memory. I know 10K series, for 1 heavy loaded core and the rest hovering at 2-5%, was ~60W for about 4.9Ghz, so I'm just extrapolating from the increase in clocks, voltage+amps and process being an extra 10W to 20W, depending on how aggressive the boost behavior is. Happy to be wrong though, but I'm sure I'm not far off.

Regards.

"A rising tide lifts all boats " Everything benefits from single core performance uplift. Even though your threads are all loaded up, what you are missing is they are still dependent on a single core path and only doing work to prepare for that dependency. A computer with 10%+ uplift single core is very noticeable improvement. I just went from 11700k (8core 16 thread) to 12600k(6P4e cores also 16 threads) and it is extremely noticeable. even though my multi-thread performance is about the same, my single thread speed is up by 18% and its much more snappier as well as running a lot cooler.
Software that is still mostly single threaded(Sometimes exclusively so) would be your office applications and scripting.

That's not how that works...
25-30% of 8 cores are not 8 cores.

Also core temp shows you the usage of a cpu over time so if a core is being used 0% for 70% of the time and 100% for 30% of the time it will show up as 30% usage and if it is being used 30% for 100% of the time it would again show up as 30% usage.

What you need is a program like process hacker that can actually show you how much each thread of the game is using in real-time and not over time.
