Something to chew on...
This is Bergamo, AMD's 128 Zen 4 core EPYC, i couldn't find any information on its clock speeds, the 2.15Ghz reported it just what the firmware in the CPU is reporting, usually base frequency.
I do have some information on Genoa, the 96 Zen 4 core variant of this, it has a maximum boost clock of 3.4Ghz.
So if we assume the maximum boost clock of Bergamo, the chip tested here, is also 3.4Ghz we can come up with some numbers for Zen 4 that are more relevant to us.
The rumour is the 7950X will boost to 5.7Ghz, take that 5.7Ghz and divide it by 3.4Ghz, gives you 1.68 (68%) add that to the 1191 score = 2,001 to proof it add 68% to 3.4 gives you 5.7.
Zen 3 scores around 1,600 at 4.9Ghz, divide 5.7 by 4.9 = 1.16 (16%) add to 4.9 = 5.7 (roughly) < that is interesting, but probably just a coincidence, the rumour is Zen 4 has 8% higher IPC, which would put the score at 5.7Ghz around 2,200, if the tested CPU here is only running at around 3.1Ghz, not 3.4Ghz, that would be about right.
