RandomX Mining Performance on AMD Ryzen Threadripper 3990X Processor (64C/128T)

25, Feb 2020

AMD’s Ryzen Threadripper 3990X Processor is the latest and highest-end workstation CPU from AMD offering staggering 64 cores and 128 logical threads to the user or with other words really massive performance if you can manage to take advantage. The Ryzen Threadripper 3990X CPU does not come cheap at a retail price of about $3990 USD it is really expensive, so most definitely not for everyone and unfortunately not the best choice for mining if you want to pay back for it mining crypto at the moment. Nevertheless we managed to get our hands on one of these monsters of CPU power and the first thing we did was to run some RandomX CPU benchmarks in order to see what level of performance we are going to get. You can read our first impressions and results below…

We have started our RandomX testing on the AMD Ryzen Threadripper 3990X CPU with the latest XMRig 5.7.0 that was just recently released and we managed to get all 128 threads at 100% and a hashrate of almost 40 KH/s. Performance wise great result, but still earning you just about 3 and something US dollars per day mining Monero (XMR) that uses the RandomX algorithm, making it pretty pointless to use that particular processor for mining. Mining ARQma (RandomARQ) got us 198 KH/s hashrate, for LOKI (RandomXL) the hashrate was 46.6 KH/s and for WOWnero (RandomWOW) the result was 49.1 KH/s when using the latest XMRig miner. Trying out the latest XMR-Stak-RX got us a bit higher hashrate at 41.3 KH/s for RandomX and the latest SRBMiner-Multi miner did perform even slightly better with 41.8 KH/s as hashrate mining Monero (XMR).

All of the miners for RandomX did manage to properly load all of the available 128 logical cores on the 3990X processor, but be aware that not all CPU miners out there and all algorithms may be able to take full advantage of so many CPU threads for mining. An example of a miner that had trouble automatically using all 128 threads is the PEGNet (PEG) miner at the Orax Pool that did put a load on only half the logical threads available or with other words only 64 threads instead of the full 128. Trying to manually fix the issue by increasing the number of sub miners to 128 from the automatically detected 64 unfortunately does not help to take full advantage of all 128 logical cores that the processor offers.

New miniZ v1.5t Nvidia CUDA Miner with Better Performance and Stability

29, Jan 2020

A new version of the miniZ 1.5t Nvidia CUDA GPU miner for Equihash-based algorithms is available and it brings extra performance, improvements and better stability. The major performance improvements are for the Equihash 150,5 and 210,9 algorithms with up to 4% depending on algo and GPU used. Nvidia RTX 2070 gets up to 8% on Equihash 192,7 as well as 1660 Ti. There are also minor performance improvements in all other algorithms with up to 2% boost, depending on algo and GPU used. The new version also has better support for GTX 1660 Ti and GTX 1070, as well as some fixes such as lower CPU load when mining Beam on Windows and cleaner program exit/termination. The miniZ miner is still our preferred choice for ZEL mining, though here we are not seeing much of a performance gain over the previous version MiniZ 1.5s.

The MiniZ miner supports Equihash 144,5, Equihash 150,5, Equihash 150,5,3, as well as Equihash 192,7, Equihash 125,4, Equihash 210,9 and Equihash 96,5 and the various crypto currencies that use these algorithms on compatible Nvidia GPUs. There are CUDA 8.0 and CUDA 10.0 binaries available including support for Nvidia RTX GPUS with the CUDA 10 release (check which version works better on older GPUs, CUDA 10 is required fo RTX). Have in mind that since miniZ is a closed source miner there is also a built-in developer fee of 2% percent included.

New SRBMiner-MULTI Miner 0.2.0 Beta With Support for New Algorithms

26, Dec 2019

The latest SRBMiner-MULTI CPU and AMD GPU Miner version 0.2.0 has added support for another RandomX variant, namely the RandomV algorithm (MoneroV) as well as some additional tweaks, you can find the full changelog below. The previous release has also added support for the RandomSFX algorithm (SafexCash), so you can say that there is revival for CPU mining lately centered around RandomX, unfortunately that also has some negative side effects such as botnets mining. We’ll see how things go and for how long RandomX will remain in the CPU mining domain only with the growing interest around it and with many different variations becoming available as well.

SRBMiner-MULTI CPU & AMD GPU Miner 0.2.0 beta changelog:
– Added RandomV algorithm (MoneroV)
– Added –randomx-use-tweaks, to select the MSR tweak/s to apply
– Added RandomX tweak support for Intel Core2 processors
