I used the tables in this article to relate performance of the new Intel processors with processors all the way back to X5650. From that I can estimate a hepspec value.
The estimated results I'm using are
Intel silver 4116, QMspec = 514
Intel gold 5118, QMspec = 557
Intel gold 6126, QMspec=628
For AMd I had to look at a range of benchmarks comparing AMD to Intel and then guess a value for HepSpec, these are more guess work then estimates.
AMD 7301, QMspec=616
AMD 7351, QMspec=668
Disclaimer: Note theses are guesstimates so I've called them QMspec rather than HepSPEC ;)

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

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?
