The latest SRBMiner-MULTI CPU and AMD GPU Miner version 0.1.6 brings some improvement in CPU mining performance thanks to better utilization of processor threads, though it seems that further optimizations might be needed. In a quick test with RandomX-based algorithms we are seeing an improvement in hashrate compared to the previous SRBMiner-MULTI 0.1.5 that has introduced RandomX support, but full thread utilization may still not at 100% for all processors and performance is a bit lower when compared with XMRig on the same mining hardware, still it is good to see that efforts are being made for further improvements.

SRBMiner-MULTI CPU & AMD GPU Miner 0.1.6 beta changelog:
– Fixed threads binding on systems with more than 1 numa node
– Better auto configuration for cpu mining
– Previous two fixes should bring higher hashrates
– Added pool controlled algorithm switching capability (Monero Ocean)
– Added pool config parameter “algo_min_time” and --algo-min-time to cli (Monero Ocean)
– Added pool config parameter “keepalive” and --keepalive to cli

Update: There has been an update that fixes issues for SRBMiner-MULTI 0.1.6 that corrects the less than 100% load on all cores/threads of the processor, so now the performance is even better and should be pretty much the same as what XMRig currently offers on the same mining hardware as far as RandomX and its variants are concerned, so just redownload version 0.1.6 if you downloaded the initial release.

We have already mentioned the plans of ArQmA (ARQ) to fork to a new RandomX-based algorithm called RandomARQ and that has happened a few days ago and we have tried CPU mining the new algorithm. Since it is based on RandomX we expected to see significant advantage for the latest AMD’s Ryzen CPUs like we’ve seen with RandomX and some other variants of the algorithm used by other projects. To our surprise however Intel’s multi-core processors are actually not that far behind in terms of performance (a few times slower like on RandomX). Of course Intel is still slower, but the actual difference is not as much as we’ve seen so far and that is definitely good news for miners that have some spare Intel CPUs that might be interested in mining something based on RandomX.

We have tested performance using the latest XMRig miner and SRBMiner-MULTI miner with the seond one still performing slower as we have seen with other RandomX algorithms compared to XMRig. With an AMD Ryzen 3600 using XMRig we are getting around 22.8 KH/s while on Intel Core i7 6850K CPU we get about 17 KH/s, both being 6 core – 12 thread processors though the AMD one is much newer product. With SRBMiner-Multi the results were 13.4 KH/s with the AMD and 7.8 KH/s for the Intel CPU, so you better stick to XMRig for mining ARQ for now and you might want to also test your Intel processor(s) as well for the RandomARQ algo. The not so good news however is that profit for a single CPU mining ArQmA (ARQ) is well nonexistent, unless you do not pay for electricity… 20 USD cents per day for the Intel and 30 for the AMD processors. These dayly earnings could probably just cover your electricity costs if you have cheap electricity at 10 USD cents per kilowatt.

The latest SRBMiner-MULTI 0.1.5 miner has introduced support for the RandomX and its few variants for CPU mining, something that we were eagerly anticipating to see and to compare the performance to the already available XMRig RandomX CPU miner. SRBMiner-MULTI 0.1.5 supports CPU mining of RandomX for the upcoming Monero (XMR) fork, the variants RandomXL for LOKI and RandomWow or Wownero that are already using their new algorithms for mining as well as the RandomArq for the upcoming ArQmA (ARQ) fork. There are some new features, improvements and fixes as well that might be helpful and useful with the new release, so you might want to check out the full changelog.

The most important question is what performance to expect from the atest SRBMiner-MULTI and the RandomX algorithm compared to what XMRig is already delivering to CPU miners? Well, unfortunately it seems that so far SRBMiner-MULTI will need to do better in order to catch up to the performance level tat latest XMRig is delivering, at least on AMD’s Ryzen 3xxx series of CPUs that do seem to be delivering one of the best RandomX hashrates out there for the moment. We have tested and compared both miners on an AMD Ryzen 5 3600 CPU (6 cores, 12 threads) and the results are significantly in favor of XMRig. While SRBMiner-MULTI CPU manages to deliver around 3000 H/s in our tests, the same system manages 5500+ H/s, so you might want to stick to XMRig for now until SRBMiner-MULTI gets further improved performance. With an Intel Core i7 6850K processor (6 cores, 12 threads) the XMRig does 2500 H/s while SRBMiner-MULTI CPU manages to deliver just around 1500 H/s and it seems that the slower hashrate is a direct result of the miner not being able to fully utilize 100% of the available processor resources. The overall CPU load for SRBMiner-MULTI mining RandomX is just around 50% and not full 100% percent that it should be with the miner fully using all 12 threads of the processor.
