...Now that Diesel based system would make a beast of a workstation 128 CPU cores, 128 GB Octo Channel DDR4.
Here's a 64-core/256-thread Xeon Phi x200 (Knights Landing) running Cinebench R15 w/ 6-channel DDR4 and 16 GB of HMC (probably setup to act as L3 cache).

As he says, it's not using any KNL optimizations (such as AVX512), so the score is only slightly better than Ryzen's: 1648. Remember, it's just 64 Silvermont Atoms that've been extended to support 4x hyperthreading + AVX512, running at 1.3 GHz.
Interestingly, you can configure that CPU to act like a quad-CPU cluster. If he did that & setup a render farm, the result would certainly be better. If he then enabled AVX512, I wonder if he could even double the score.
BTW, according to this, the top Cinebench R15 score is 4918 - achieved by a dual E5-2699 v4 Xeon (44 Broadwell cores @ 2.2 GHz):
