By the time you got some "whizzy" machine, it would
already be obsolete :-) Some people learned that, by
buying a new laptop with a too-weak NPU in it, then Microsoft
announces they want a stronger NPU. That's the kind of
reward you get, for buying new.

I had two machine die (chipset), so that put me in the market
for a new one.

The techpowerup article, lists the 32M SuperPI 1.5 time as 354 second (a little
less than six minutes) for my processor.

On my machine here, I get 358 seconds on Win10 (4 seconds slower)
and 374 seconds on Win11. The run to run variation is a lot higher than
I'm used to, and that's because of the closed loop control on the newer
machines (turns down speed if it's too hot, basically). Even though the
cooler is rated at 250W, there are still signs that more cooling would
be better. On machines in the past, you only worried about cooling
as far as "Tmax" was concerned, but now you have to consider "what
the machine thinks of your setup", which is not the same thing.
If the machine seems "nervous" or "twitchy" in CPUZ, then the
cooling likely isn't good enough.

The RAM in the machine is DDR4-3200 CAS16, so pretty tame stuff.
It's possible the DDR4-3200 JEDEC is CAS22.
