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.
