Looks like they do have some AMD systems, which appear to give more bang for
the buck than Intel; but it's still overkill for me, with their liquid-
cooled setup.
I think AMD provides/requires their own liquid cooled system.
If you plan to run a high-end i9 cooling will be an issue. At my former work there
are lots of Dell Xeon workstations. My group snagged one with dual 12-core CPU's
for remote sensing applications, but when I turned it on my 1500kV UPS was
overloaded. On investigation I discovered it had been configured to run tasks
in a distributed numerical model at startup. After configuring for a softer start the
UPS was OK, but in normal operation it would pull over 800 watts. I think those
CPU's were 250 TDP and core i9's are 165, so you might get down to 300 watts
with one i9 at full throttle. If you are in Alaska or on top of a mountain and don't
have high-end GPU's you might get away without room A/C and liquid cooling, but
vendors have to plan for a range of environments.
Have you considered renting cloud capacity for your compiles? I see many
people using cloud systems who work with large existing C++ codes, fixing
bugs or adding features, but developing a big system from scratch might
be a stretch. Many people use laptops as their main system, which allows
them to move around and has built-in UPS (in Europe many people work on
trains, using mosh to get a bash shell in the cloud).
Google has a free introductory offer of $300 worth of cloud services.
