Why do the world's best Supercomputers use Intel Xeon E5 chips or something, instead of AMD's Epyc Rome 7742 or Threadripper 3990x as those things offer higher clocks and more cores

(I'm not really familiar with server gear)

But as far as I'm aware AMD only recently got competative on the server side, so it could be that those sc are "too old" for amd? Or it has to do with those being specially built for these supercomputers?

(only some thoughts)

Servers are all about longevity and don't upgrade as frequently. So, AMD will need to wait a few years in order for everyone to transition.

its not about higher clocks and frquenzy.

 

its about:

power usage

heat

IPC

use Intel Xeon

Momentum, inertia. 

"We've always used Xeons, so we will always continue to use Xeons."

 

And I say this as someone who is a big fan of using Xeons in home systems.

It's going to take a few years for AMD to get their foot in the door on the server world.

 

Plus don't forget the Opteron servers weren't such a great value, businesses have a long memory...

I know some supercomputers that are using EPYC and are planning to scale up to 2 ExaFLOPS while saving prices due to its low price
