Obviously, a T is not in the same class as a K !!!

At one time, we had just the concept of TDP to worry about.
Today, some of the processors no longer have the concept
of a "base clock". The datasheet leads you to believe
they "run from 0..MaxTurbo". And then, there is a continuum on
power, just as your 14700K is 125W base, and 253W on turbo.

The T version, if you can find the datasheet for it, it
is not going to have the same "top-clock". If it DID
have the same "top-clock", then all that would mean
is the power limit on turbo is 250W or so. You can't
have a top clock, without some increased VCore voltage
and a hefty thermal output.

The difference between 3.5GHz and 5GHz, is Windows Update
finishes a bit more snappy. That's on an email/web browser
machine. If you're gaming, the battle scene frames
on the screen "turn blurry" when there isn't enough CPU
to paint the frames. Once the 5GHz is available, the
scene should be crystal clear.

It all depends on what you want to do with the machine,
as to whether a T serves a purpose or not. A lot of
the time, you can't even find a T on Newegg to buy. That
used to be the problem with those, is they were in
pre-built machines, but not a lot of them leaked to retail.
They share some characteristics with laptop processors, in
terms of the voltage and frequency selection used.

If your plan is to use a 35W CPU, then you could cool that
with a wet rag. It wouldn't take much of a cooler. My blow-down
cooler could handle that (and if you let it, it could even handle
the idle CPU with the fan off). Whereas a 253W processor, if
you're doing a 7ZIP run and compressing a 3TB backup image,
then your cooler choice has to sustain good operating
temperatures, during the extended compute run. 7ZIP is the
equivalent of a "burn-in software".

Since AMD has been on a price-dropping spree recently,
some of their lower power processors have lost the in-box
cooler, and so buying a cooler is now an extra step for them.
You could get good performance from a 65W CPU, plus with
the right motherboard choice, the AMD also have ECC support
across more of the product line.

DDR5 has two kinds of ECC capability, and the traditional
extra-chip kind is what you want when doing an ECC box. A
USENET poster went through a living hell, getting that to work,
and he never did deliver his "Linux numbers" that prove the
memory controller is in the correct operating mode. That's how
you figure out (partially) that it is working.

With the DDR5, there is also an error-injection capability, so
you can actually shoot in an error, and see an error appear in
the log as a proof of ECC-purchase. It takes a software to run the
error injector.

I would not blame you for selecting your current mobo choice,
if it meant less work getting ECC to work.

Always double-check, that the handful of components you are using,
really are "ECC ReadY" and it is not s sham. I got screwed out of
ECC on my X48, via various press releases (will-she-or-wont-she).
I had ECC DIMMs but the BIOS gives the bad news "it won't work".
Design-error in chipset (X48).

These are purchase patterns for the RAM.

    4x32GB DDR5 ECC  (suited to a highly reduced clock rate of operation)
                     (slower speed, caused by bus loading of two DIMMs per channel)
    or

    2x48GB DDR5 ECC  (the "odd" sized DIMMs can be used and ECC ones are available)
                     (One DIMM-Per-Channel allows the highest operating clock)

    plus

    1x8GB non-ECC DDR5  (this is the single DIMM you put in the motherboard while
                         flashing up the BIOS. You also use this stick, when the
                         motherboard won't start any more, despite resetting the CMOS,
                         and the last ditch effort, is to put the non-ECC single stick
                         back in by itself).

Always have that teaser-DIMM ready, on these high tech builds. I didn't need that
on my builds - I spent the first evening working in the dark, nothing would
run, the BIOS flasher LED was flashing (but it wasn't doing anything). But
I eventually got it running after "trying all permutations and combinations"
as a technique :-/ On one combination, suddenly the LED frequency was different...
