CPU Mining the Coin Magi (XMG) What Can You Expect

7, Mar 2015

We are closely watching the Coin Magi (XMG) development as for the moment it is still pretty much the most actively developed alternative crypto currency that continues to be mineable with CPU only and there is no GPU miner for it available. The developers just recently announced the release of MagiPay, a Standalone Payment Gateway for Coin Magi. The ongoing development as well as the wide accessibility due to CPU mining is important as it allows pretty much anyone to be able to mine XMG on his own computer, though based on the processor used the results in terms of performance can vary. Still the ability to mine the coin on every computer and the fact that you can still mine it even though the current reward per block is lower (variable between 0.0001 mining fee and 50 XMG) that it was initially is what makes the coin attractive to a wider audience. Also the fact that the Coin Magi is traded on some big altcoin exchanges such as Bittrex and it has a pretty stable exchange rate does help to keep the users interest in the coin. There are currently five pools where you can mine XMG directly and a multipool where you can get paid in XMG.

To test what hashrate we are going to be getting on a modern high-end CPU we have tested the highest performing CPU miner available for mining XMG from Wolf0 on an Intel Core i7 5820K processor running with 12 threads on this 6-core CPU with Hyper Threading support. We have tested all the various optimized binaries of the miner on that processor to see what results we are going to get with each one and which one hash the highest performance, you can see the results below and you can also download the miner to try out on your processor from the link below.

Hashrate on Intel Core i7 5820K:
minerd-x64-athlonfx.exe – 115.68 KHS
minerd-x64-avx.exe – 116.98 KHS
minerd-x64-avx2.exe – 116.10 KHS
minerd-x64-avx-i.exe – 117.48 KHS
minerd-x64-bdver2.exe – crash
minerd-x64-btver2.exe – 117.72 KHS
minerd-x64-core2.exe – 116.92 KHS
minerd-x64-corei7.exe – 117.65 KHS
minerd-x64-generic.exe – 117.79 KHS
minerd-x64-haswell.exe – 116.26 KHS
minerd-x64-ivybridge.exe – 117.68 KHS
minerd-x64-nocona.exe – 116.31 KHS
minerd-x64-sandybridge.exe – 117.63 KHS
minerd-x64-SSE2.exe – 117.53 KHS
minerd-x64-westmere.exe – 117.70 KHS

Interestingly enough the difference in terms of performance between the lowest performing and the highest hashrate version is in the range of just about 2 KHS which is not that much. Another interesting find is that apparently the generic version of the miner does manage to get the best results on the 5820K CPU (Haswell-E) processor.

What Hashrate to Expect From an Up to Date CPU

Using the CPU or the central processing unit of your computer to mine crypto currency is pretty much considered outdated nowadays with the only exception being mining new altcoins that are CPU only. If you are interested to find out what hashrate you can expect to get from a powerful multi-core CPU at the moment with come of the more popular crypto algorithms in order to compare to your AMD Radeon 280X GPU or Nvidia GeForce GTX 750 Ti for example, you might want to look at the results we got below. They are achieved using the cpuminer-multi fork on an Intel Core i7 5820K processor (6 core with HT or 12 logical cores) running at default operating frequency (non-overclocked).

Algorithm – Hashrate:
Scrypt – 129 KHS
Scrypt:N – 26.2 KHS
Sha256d – 10.7 MHS
Blake – 18024 KHS
Cryptonight – 192.7 HS
Fresh – 487.2 KHS
Lyra2 – 744.8 KHS
Neoscrypt – 22.2 KHS
Qubit – 488 KHS
Quark – 664.8 KHS
X11 – 308.1 KHS
X13 – 211.4 KHS
X14 – 202.6 KHS
X15 – 194.4 KHS

The cpuminer-multi fork that we used for the test does support more algorithms than those that we tested with, we’ve skipped some because it is hard to find operational pools or even alive crypto coins to use some of them. So we did not test all of the algorithms such as S3, NIST5, Pentablake and a few others that are supported by the software miner. Use these numbers as a reference only for comparing to GPU mining hardware as you probably will not want to use your CPU to mine with on these algorithms anyway. The only exception being Lyra2RE, because this algorithm does provide a very decent hashrate on the CPU as compared to what you can get with a GPU miner.

GPU Mining Heavycoin (HVC) Booming, Price is Still High

18, Mar 2014

Now, more than a day since the release of a GPU miner for AMD graphics for mining the previously announced as CPU only crypto Heavycoin (HVC) is available, surprisingly the price of the crypto is still at high levels. The release of GPU miner already made the mining of the coin with CPU pointless, and the coin is already not so easily mineable with GPUs with the network hashrate already pretty high. Mining HVC with AMD GPUs however may be worthwhile for some more time if you have some AMD Radeon cards to spare if the exchange rate does not start to drop. We still haven’t gotten a release of a HVC miner for Nvidia that uses CUDA, but the author of CudaMiner is working on such software. The interest in Heavycoin is still quite high and you should not be dismissing it so easily.
