Ivan,
Here is the specfp2006 on the 6126. I can try tracking down the others
The CERN benchmarks for meltdown after the fixes are only showing a 2-4%
slow down, but maybe it gets worse when a set of reliable fixes are available.
Also not sure how dangerous the bug is for a set of machines sitting behind
a firewall and accessible through a server machine. What is Raul's opinion

Hi;
We're evaluating some offers for new machines, but the CPUs being
offered are new enough that I'm having trouble finding any comparisons or
benchmarks, let alone HEPSPECs. Does anyone know of any comparisons between
these compute CPUs?
Xeon 6126, Xeon 6130, Xeon E5-2683v4, EPYC 7501
Also, is there any consensus on the desirability or otherwise of
shunning Intel to avoid the Meltdown slowdown?
Thanks,
ivan
