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Using the CPU or the central processing unit of your computer to mine crypto currency is pretty much considered outdated nowadays with the only exception being mining new altcoins that are CPU only.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.

Thanks for this, I use your website as a reference and for new releases of miner software and coins all the time. Really appreciate all the work you do, saves us miners a lot of time. Thanks!

Is this per-core or total?

According to MyriadCoin spreadsheet a 4930k would push ~1600 khs/Qubit.

But… if this is per-core then it’s pushing 2940 khs, which is already an excellent improvement, unless we consider it per-thread at which point it would go over 5M…

The hashrates cited above are the total for all the cores/threads of the CPU.

Do note that the cpuminer-multi may not have optimizations for certain aglorithms that are available in dedicated CPU miners and is not specifically compiled for the features of 5820K, it is just a CPU miner that comes with support for many algorithms in one place. So higher hashrates are possible, also overclocking can further increase the performance…
