Intel Xeon CPU is used in servers and was popular before AMD destroyed Intel. Use the CRC memory when it must be used.
But for AMD Ryzen or Threadripper, Xeon is not required in the consumer/workstation space. It’s too expensive. It’s hot and slow.
In the server market, AMD Epyc is destroying Xeon.
Only really for programs that require AVX512, because AMD still doesn’t support it. But the newer Epyc/Threadripper may change that.
It doesn’t make sense to use them among consumers because the power consumption is very high.
For example, I have a Dell Server with Xeon 4XXX and Windows Server 2012. When the server was running overnight and idle, my electricity bill more than doubled before I shut it down.
Today the Ryzen 5800 is more powerful.
