Still I wasn't sure how to compare the real life speed of POWER9
compared
to something like the AMD EPYC 7601.
It probably depends on the workload.
And then, will everything work smooth
on POWER the same way it does on the AMD?
AFAIK, there were a lot of microcode-updates from AMD to fix bugs in the
first batches of Threadripper and Epyc.
It was not smooth sailing from the very beginning.
POWER seems still not a first
preference arch for CentOS, so how would it impact us? Is it smart to
add
another CPU arch if we still have to run some X86 code, like in our
case
SAP MaxDB (which is also available for AIX on POWER but not Linux on
POWER)?
In the end we decided for AMD EPYC but kept the POWER thing in mind.
Now
that IBM announces the purchase of RedHat it just reminded me that this
could become interesting again in the future. Let's see how it goes.
