New SRBMiner-MULTI CPU and AMD GPU Miner 0.1.5 Beta With RandomX Support

7, Nov 2019

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.

CPU Mining on the Kadena (KDA) Public Blockchain

5, Nov 2019

Kadena (KDA) is a few years old startup company with serious financial backing that has just recently launched their public blockchain and it promises some interesting things including support for tens of thousand transactions per second with multiple blockchains. Kadena is supposedly offering a blockchain that is faster, more secure, and more scalable than other crypto projects and on top of that it is being done with Proof of Work, so mining is possible for anyone that might be interested. Kadena also supports smart contracts and comes with its Pact smart contract language described as the first truly human readable smart contract programming language that should be easy to be used by more users and not just advanced programmers.

For the moment Kadena can be mined only using CPU, no GPUs, FPGAs or ASIC miners, so good news for anyone with some CPU resources that can be utilized for mining. The not so good news is that for the moment the chainweb-node and miner used by Kadena is still only available for Linux and Mac OS users only, so no Windows binaries are available. This means that you cannot yet run a full node or mine if your mining rigs are running Windows OS or even if you are running on most of the specific Linux-based OSes for mining, unless you add the required support yourself. Here you can read more on mining for the Kadena Public Blockchain if you are interested. Mining is either done by running a local full node or with a remote node supporting mining and just the miner software that is packaged inside the chainweb-node.

New XMRig 4.5.0 Beta With Unified CPU and AMD and Nvidia GPU Support

3, Nov 2019

The XMRig miner is what you would go for if you are interested in mining the RandomX CPU algorithm or any of its variations. While the miner does support CPU and GPU mining for RandomX and other algorithms up until now you had to download separate versions depending on the type of mining hardware you wanted to use, but this is needed no more. The latest XMRig 4.5.0 beta release comes as a unified 3 in 1 miner that supports CPU mining as well as AMD and Nvidia GPU mining. Of course if you are only interested in RandomX mining then you probably want to use CPU mining as GPUs do not perform nowhere near as good as a more recent higher-end multi-core processor does (especially the latest AMD Ryzen CPUs). Then again XMRig does support a number of other algorithms as well and RandomX is not as usable and interesting as of this moment anyway, though in the near future things may significantly change… who knows.
