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.

Best CPU to Mine 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 RandomX Mining Hashrate

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.

Ryzen Threadripper RandomX Mining

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:

	For Ryzen 5,7,9 CPUs MSI X370 GAMING PRO CARBON or mining edition motherboard that has been upgraded to support thew new Ryzen generations Biostar TB350-BTC AMD For Ryzen Threadripper CPUs GIGABYTE X399 AORUS PRO or ASRock X399 Taichi
	For Ryzen 5, 7, 9 (3rd gen) HyperX Predator DDR4 RGB 16GB kit 3200MHz For Ryzen Threadripper (3rd gen) HyperX Predator DDR4 RGB 16GB kit 3200MHz For Ryzen Threadripper (2rd gen) HyperX Predator DDR4 RGB 16GB kit 2933MHz
	Kingston 120GB A400 SATA 3 SSD
	PSU of 500W-550W if you want to keep it minimalist 600W or more if you want to add a couple HDD drives to mine STORJ It is possible to add 2 GPUs like the the ones below to increase RandomX hashrate with 2,000 H/s or can use CudoMiner for profit mining, however the return on investment isn’t that great for now (on avarage $1-$2/day), the performance boost you will experience will equal that of a low-end GPU. In exchange, you’ll need a more powerful PSU CORSAIR RM1000x, 1000 Watt, 80+ Gold Certified
	Optional 1 or 2 GPUs (or more, depending on what you intend to build) Sapphire Nitro+ RX 5700 XT 8GB GDDR6 MSI GEFORCE GTX1080 TI GAMING X 11G MSI RTX 2080 TI GAMING X TRIO
	Optional for HDD Storj Stoare Nodes or SIA Hosting Seagate IronWolf 3TB NAS Internal Hard Drive HDD – 3.5 Inch Seagate IronWolf 6TB NAS Internal Hard Drive HDD – 3.5 Inch Seagate IronWolf 10TB NAS Internal Hard Drive HDD – 3.5 Inch
	Optional CPU water cooling system Stock fans get the work done, however depending on your ambient temperature and rig condition, you might want to get a water cooling system. In case you need one, here’s what I would recommend you getting: CORSAIR HYDRO SERIES H60 AIO Liquid CPU Cooler, 120mm Fan
	Closed PC Case : Thermaltake V200 ATX Mid-Tower Chassis with 4 120mm Fans Pre-Installed Open Benchmarking Frame: ATX PC Test Bench Open Air Frame Mining Frame: 6 GPU Aluminum Mining Frame Rig Case

The pros of building a rig from scratch are:

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:

In Conclusion

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.
