Revisiting PegNet (PEG) CPU Mining At The Orax Mining Pool

16, Mar 2020

It has been a while since we have last talked about PegNet (PEG) CPU mining at the Orax Pool, so we have decided to check if there is any development lately. Well, there is apparently a new miner since the last time we have tried that increases performance significantly and it is well worth updating your mining software if you are using older one. Three or so months ago when we tested performance at the Orax Pool an Intel Core i7 6850K (6C-12T) processor was giving a hashrate of around 65000 H/s LXRHash algorithm (using version 1.0.10 of the miner). Now, the latest version 1.1.0 of the mining software results in almost double the performance of the older version with about 110 KH/s. And if you happen to have an AMD Ryzen 9 3900X (12C-24T) processor you could be getting up to about 140 KH/s with the latest miner.

Unlike with RandomX for instance where the latest AMD Ryzen processors have some advantage over Intel CPUs, here with the LXRHash algorithm used by PegNet (PEG) it seems that Intel does have some performance advantage. Of course the newer and faster Ryzen 3900X with its 12 cores and 24 threads does manage to outperform a 6 core and 12 threads Intel, but not by that much. So if you have a latest generation Ryzen processor you might be better off mining some other CPU coin. Recently we have tried even the fastest AMD Ryzen Threadripper 3990X with the PegNet (PEG) mining on the Orax Pool with the latest miner and it did manage to provide us with around 350 KH/s of hashrate for the LXRHash algorithm. The problem with the Threadripper 3990X is that he miner could not use more than 64 threads and while the processor does have 64 physical cores it has a total of 128 logical cores, so the miner could not fully utilize the available hardware, otherwise the actual performance should be higher.

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.
