Configuration notes:
I had about two weeks over the Christmas break 2021 to receive all of the hardware, assemble the systems, and get the systems set up and up and running. And that was quite the endeavour because with the latest and greatest hardware, the older versions of CentOS (7.7.1908) and the older kernel didn't work with all of the features and functions with this level of hardware.
As a result, I had to "jumpstart" both systems by first installing the OS using my Intel Core i7-3930K system (Asus X79 Sabertooth motherboard, 4x Crucial 8 GB DDR3-1600 unbuffered, non-ECC RAM, Mellanox MCX456A-ECAT, GTX 660) first, and then update the systems (at least in part) before I can transplant the hard drive with the OS install into their respective systems and finish setting the systems up. (I will write more about that "journey"/clusterf in another blog post here shortly because it was quite the journey to jumpstart both of these systems simultaneously, which took pretty much the full two weeks that I had.)
You will find out how and why I ended up with the respective hardware choices in that blog post.
I am using cpuminer-gr-1.2.4.1-x86_64_linux from here (https://github.com/WyvernTKC/cpuminer-gr-avx2/releases/tag/1.2.4.1).
For the Intel system, because of the existence of the combination of (P)erformance Cores and (E)fficiency Cores and HyperThreading, this resulted in more combinations that I had to test in order to find the setting that had the highest Raptoreum hash rate as reported from their benchmarking tool. Each time the CPU configuration changed, I ran a full tune again, which you might well imagine, took quite some time to do. In the cases where the efficient cores were disabled, I also tested and re-ran the full tune for both AVX2 and AVX512.
The AVX512 runs (both times I ran it, i.e. with and without HyperThreading), resulted in thermal throttling with about a 23-24 C ambient at the time.
For the AMD system, testing it was a lot simpler because it was either only SMT on or off.
Results:
The results speak for themselves.
The AMD Ryzen 9 5950X with SMT enabled produces the highest hash rate (3953.64 hashes/second). Compare that with the run where SMT was disabled, enabling SMT results in about a 10.3% increase in the hash rate performance result.
The Intel Core i9-12900K results are an interesting case. Despite the plethora of benchmarks talking about how great and how fast the latest and greatest from Intel is (and there ARE some things that said latest and greatest from Intel are great at), unfortunately, for Raptoreum mining, this is not one of them.
At best, the 5950X with SMT enabled compared to the 12900K with all 16 cores AND HyperThreading enabled puts the 5950X at about 80.9% faster in Raptoreum hash rate performance vs. the 12900K.
Comparing like-for-like thread count, whether it is 8P+8E without HyperThreading, the 16 core/16 thread of the 5950X is still approximately 64.2% faster than the 12900K. Without the efficiency cores, but turning HyperThreading back on (i.e. 8P+0E with HyperThreading), the 12900K again is bested by the 5950X by a 71.8% margin.
Unfortunately, running this in Linux meant that I didn't have or didn't know of a tool like Hardware Info 64 to be able to report power consumption figures/values. Maybe I might get around to re-running this test again in Windows, but for now, this might be helpful to those who might be interested in looking for guidance if mining Raptoreum is on your mind.
