Is Ubuntu 19.04 able to support Intel Core i9-9980XE Extreme Edition or AMD Ryzen 9 3950X?

[Kevin O'Gorman]

I've got a desktop from System76 that's running dual Xeon E5-2620 cpus, 16
cores and 32 threads.  No problem.  I could have ordered more cores and
faster everything.  No problem.  They have even better stuff now.
