Question Intel K vs. non-K CPUs

[Turbonium]

As I understand it, if I want the most capable CPU possible from Intel at stock, I'd have to get a K series (with unlocked multiplier), even if I'm not planning on overclocking. Is this correct?

(I suppose what I'm asking is if the base frequency of, for example, a 13900 being much lower than a 13900K really matters when their turbo clock is almost the same.)

As per this article:

AnandTech	Cores P+E/T	P-Core Base	P-Core Turbo	E-Core Base	E-Core Turbo	L3 Cache (MB)	IGP	Base W	Turbo W
i9-13900K	8+16/32	3300	5800	2200	4300	36	770	125	253
i9-13900	8+16/32	2000	5600	1500	4200	36	770	65	219

at stock,

The numbers you show are the intel stock and yes with the non-k only having 65W at base it would be much slower.
BUT as all the reviews already showed almost no mobo maker keeps to intel stock settings, in real life the non-k will get the same unlimited power setting as the k version does and the difference will be with the 1-200Mhz turbo numbers and with power and thermals possibly because the k version is probably a better bin.
Also intel stock would be a TAU (turbo duration) of 56 sec, they do allow an unlimited time for TAU under warranty but stock would be for a very small turbo window
