As for today, RandomX is the newest and most profitable CPU-minable algorithm. It has been designed to repel ASICs, FPGAs and even GPUs. As the name suggests, the algorithm is based on random code execution and memory-hard techniques.
The main idea behind a CPU-minable coin is to improve decentralization by getting as many different people into mining. You’ve heard it right, different people, not a handful of people with a gazillion mining rigs stacked in a farm.
So far, this coin probably the most profitable to mine on an already existing mid-high tier gaming rig. Any gamer out there can quickly and easily install the miner and use their PC to hoard cryptos at night. The simplest way to start mining Monero RandomX is CudoMiner, with plenty of settings.
Building a rig specifically to mine RandomX is pretty tricky. Building a profitable GPU rig is way easier than a CPU one, main reason being that it’s possible to connect multiple GPU’s to one motherboard whereas each CPU usually needs its own motherboard, memory and hard disk drive. CPU rigs are bulkier, more expensive and yield less than GPU ones.
However, there are ways of making CPU mining profitable. Let me show you three ways you can profit by mining RandomX.
Since the CPU is the one doing the work, let me start by listing the best CPUs to mine RandomX coins. I have done the homework for you on this one:
You will see a lot of AMD processors in this list simply because the algorithm is mined faster on multi-core and multi-thread processors, and AMD Ryzen series are leading in those areas for now.

AMD Ryzen 7 RandomX Hashrate
AMD Ryzen 5 RandomX Hashrate
(*) Hashrate can vary depending on your hardware and ram, also miners updates and optimization (**) Same as the hashrate, those benchmarks are not perofrmed by me YET, planning to do it soon, power draw can have -+ 10w-15w
AMD also has some bigger toys to offer, which are the Threadripper and EPYC processors with 16 – 32 cores. Those are commonly used on servers and AI development, though they are also available for direct purchase to the public.
AMD Ryzen Threadripper RandomX Hashrate
AMD EPYC RandomX Hashrate
- AMD EPYC 7742 64 Core, 128 Threads Hashrate 44,000 H/s* – Power Draw: 225w**
- AMD EPYC 7571 32-Core, 64 Threads Hashrate 16,000 H/s* – Power Draw: 240w**
- AMD EPYC 7551P 32 Core, 64 Thread Hashrate 15,500 H/s* – Power Draw: 240w**
- AMD EPYC 7601 32 Core, 64 Thread Hashrate 14,500 H/s* – Power Draw: 200w**
- AMD EPYC 7401P 24 Core, 48 Thread Hashrate 12,500 H/s* – Power Draw: 200w**
- AMD EPYC 7351P 16 Core, 64 Thread Hashrate 10,500 H/s* – Power Draw: 200w**
When it comes to choosing which RandomX coin to mine, it all depends on the current market. I will list a handful of the most popular ones. Do keep in mind that this list is expanding every month since more projects are getting interested in migrating to RandomX:
Ways of Building a RandomX Mining Rig / PC
I’m going to show you three ways you can jump into the RandomX mining train the most efficiently. Depending on your budget and preferences, you might want to either build a new rig from scratch or overhaul an existing one you already have to mine with the most profit.
Best hardware for CPU mining Rig

This step if for those of you who are looking forward building a rig and would like to get the most for your money.
1 Brand new CPU Mining Rig w/ or w/o GPUs
Here is a list of components you will need:
The pros of building a rig from scratch are:
- Universality. A CPU mining rig is not attached to one single algorithm, coin or project. ASICs are getting a lot of hate lately so it’s very probable that more coins will move to CPU-only in the near future.
- Expandability and modularity. It’s possible to add GPUs and hard disk drives to a CPU rig, hence expanding the amount of profit it brings. Any GPU rig needs a motherboard, a CPU and RAM anyway, so why not combine both?
2 Updating an Existing AMD Rig to Mine RandomX
Not all new CPUs are the best value for the money to mine RandomX. If you already have a rig with an AMD motherboard, you can upgrade the CPU and RAM alone to make the rig more efficient at mining RandomX, depeding on your motherboard’s socket. Once again, this could be a GPU and/or HDD mining rig. By swapping the CPU and RAM, you don’t sacrifice the current GPU/HDD mining speed.
3 Switching Current Rigs from Intel to AMD
If you already have a complete mining rig running on Intel and you want to switch to AMD, here is what you will need:
CPU mining is not that shiny goldmine you might expect, however it comes with its pros. The main being that a CPU mining rig is pretty much a powerful PC you can use for video encoding, gaming, GPU mining, HDD mining and other tasks other than CPU mining.
Building a CPU mining rig is pretty straightforward and easy, and I hope this little review helped you to chose the best CPUs and setup that will get you the most cryptos.
