DDR5 is two channels per stick. Two DDR5 channels is four channels total.
Yes, there is bound to be page interleaving and better
performance on a certain stride through memory.

You're a technical user, and should have enough memory for technical user things.
For example, I can run an AI on the machine across from me,
because the machine has 128GB of RAM. For your current arch pursuit,
2x48GB is the best compromise setup (to retain a good memory clock
plus gobs of RAM).

*******

The evidence in the room, makes me a "steam powered" guy.
We just can't seem to get the snappy performance, by using
any old thing. Only my 5GHz box does some things "with authority",
while the other boxes are more of a "you'll have to wait" thing.

I want my computers, to run "as intended", not perpetually be
"below the median".

Your two processor specifications, suggest 92W to 253W makes the diff
between 5.1GHz and 5.3GHz. I don't know enough about the architecture
of these, the die split, to know whether some have the "per-instruction overclock"
while the others do not. The 14900K was one of the ones, being degraded
by the choices made when the microcode was done -- this can be patched
via a BIOS update.

14600K
Intel Speed Shift Technology          Yes     (Uses P-States and clock multiplier)
Intel Turbo Boost Technology          2.0     ("Turbo Boost 2.0 boosts all cores")  Essentially custom SpeedStep
Intel Hyper-Threading Technology      Yes
Enhanced Intel SpeedStep Technology   Yes     (Used to use two specific P-States...)

14600T
Intel Speed Shift Technology          Yes     (same as 14600K - expect the top clocks to differ...)
Intel Turbo Boost Technology          2.0
Intel Hyper-Threading Technology      Yes
Enhanced Intel SpeedStep Technology   Yes

14700K
Intel Speed Shift Technology          Yes
Intel Turbo Boost Max Technology 3.0  Yes     (binned cores, custom "best core" identified, 1 or 2 turbo cores [SuperPI benchie])
Intel Turbo Boost Technology          2.0
Intel Hyper-Threading Technology      Yes
Enhanced Intel SpeedStep Technology   Yes

14900K
Intel Speed Shift Technology          Yes
Intel Adaptive Boost Technology       Yes     (all-core Turbo frequency, like if you locked the cores together)
Intel Thermal Velocity Boost          Yes     (+1 clock multiplier, if CPU temp 70C or less, as if that will happen)
Intel Turbo Boost Max Technology 3.0  Yes
Intel Turbo Boost Technology          2.0
Intel Hyper-Threading Technology      Yes
Enhanced Intel SpeedStep Technology   Yes     (Maybe when running WinXP native :-) )

285K (different socket, just to see the evolution -- same as 14900K)
Intel Speed Shift Technology          Yes
Intel Thermal Velocity Boost          Yes
Intel Turbo Boost Max Technology 3.0  Yes
Intel Turbo Boost Technology          2.0
Intel Hyper-Threading Technology      No      (I added this line, because they would not admit it :-) )
Enhanced Intel SpeedStep Technology   Yes

# Handy table of terminology-explainers

   https://www.intel.com/content/www/us/en/gaming/resources/how-intel-technologies-boost-cpu-performance.html

Summary: If any advantage is to be had, we can get it in 14700K, Windows Update
         finishes 30 seconds sooner.

         My opinion, just go by the clock numbers in each table, and... move on :-)
         The marketing department buys us a small advantage, but not hundreds of dollars worth.

         My 4930K was Turbo Boost 2 behavior, 3.4 to 3.9GHz. Yes, it's faster,
         but a good OS (Win10 is getting slower), can easily smother that and
         make it seem totally irrelevant. Which is why the "steam powered" part of
         me, still wants a good top-clock. It's compensating for the software degradations.

         And just because a processor runs a top clock, does not mean the internal
         counter-rotating rings or mesh interconnect for cores, feeds memory accesses
         quickly enough for the top clock to be useful. I first observed this on my AthlonXP,
         where boosting the clock did absolutely nothing. It was the FSB that sucked donkey balls.
         It was the same thing with the Celeron 300 running at 450, a pointless exercise
         because the memory was running at 300MB per second (slower than an SSD).
