Best CPU for RandomX

By now, you must have heard a lot about cryptocurrency. In fact, maybe that is what brought you here. Anyway, for those who have no idea, cryptocurrency is a form of digital money that allows its users to make payments without the process having to go through banks. It uses cryptography, which, in a nutshell, is something that involves mathematical theory and computer science. 

5 Best-Selling CPU for RandomX

Now let us head to the concept of cryptocurrency mining (also known as crypto mining). Basically, it is a process wherein transactions involving cryptocurrency are verified and added to the blockchain digital ledger. It is quite an alien concept if the idea is new to you, but simply put, it is a process wherein a computer is used to process cryptocurrency transactions and then, a reward is received based on that work. 

Monero is a cryptocurrency that promotes extreme privacy in transactions. It hides the addresses of the sender and the receiver. It used to work on the CryptoNight algorithm, but now, it works on RandomX. RandomX has been optimized to be used with general-purpose CPUs. It can operate in two modes. The first one is the fast mode (the mode best suited for mining) which requires 2,181 MB, and the second one is the light mode, which needs only 268 MB but is slower. You can use either of them and still have the same results in the end. RandomX uses random code execution and memory-hard techniques. 

Factors to Consider When Buying a CPU

1. Tasks 

If you are lucky enough to buy just about any CPU you want without caring about the price, pause for a minute. It might be better if you take a moment and think about what you are going to use the CPU for and use that to determine which one you are going to purchase. If you are only going to basic tasks such as browse the web or fill in spreadsheets most of the time, the most expensive one you can get is probably about a hundred dollars. On the other hand, if you’re going to do heavier tasks such as editing or gaming, you might want to widen your range to up to $350.

2. Price 

As previously mentioned, you shouldn’t buy a certain “high quality” CPU just because you think it is the best. There are many good ones in the market that are cheaper, and that is more suitable for you particularly if you are not going to do heavy work on your computer anyway. In addition to that, note that a higher price does not always mean a better quality when it comes to purchasing a CPU. AMD processors are relatively cheaper than its competitors, but it has been proven to be just as good as more highly-priced CPUs--if not better. 

3. Motherboard Support

Prior to purchasing a CPU, know what motherboard you are considering to use to build out your rig. Take note of socket size and the CPU gen version chipset that is best for the motherboard. 

4. Ideal Specifications

Not all CPUs work best for RandomX. Ideally, the features of the CPU you should get must be 64-bit, at least 2.5 GV of free RAM for each NUMA node, multiple channels, support for massive memory pages, IEEE 754 compliant floating-point unit (FPU), and hardware AES support.

Reviews of Top Rated CPU for RandomX

1. AMD Ryzen 5 2600 Processor with Wraith Stealth Cooler

AMD Ryzen 5 2600 Cooler - YD2600BBAFBOX
Product Highlights:
  • system ram type: ddr4_sdram

This processor functions just as excellently as other high-quality processors from other brands, but the best thing about this is that even though this one does a great job, it’s much cheaper in comparison to its competitors. One of the features of this incredible midrange CPU is the Wraith Stealth Cooler, which you’ll barely realize is actually working because it makes barely any noise. This one also has AMD StoreMI Technology which speeds up loading and boot times and enhances overall responsiveness.

  • incredible 12 cores and 24 threads of processing power
  • 4.0 ghz precision boost (up to 4.2 ghz with xfr)
  • 38mb of cache memory
  • 64 pcie gen3 lanes
  • quad channel ddr4 with support for ecc for reliable throughput

This one is a monster of a CPU. It’s probably one of the fastest ones you can get. It is great for just about anything, such as editing 4k videos, heavy design work, playing games, and streaming. This processor is so good that even if you leave it to do some hard work, it is not going to stutter, unlike most other low-quality ones in the market. Despite its speed and its ability to run very smoothly, it is super quiet. 

3. AMD Ryzen 5 1600 6-Core Unlocked 65W Desktop Processor

AMD Ryzen 5 1600 Cooler YD1600BBAFBOX
Product Highlights:
  • frequency: 3.6ghz precision boost
  • 6 cores/12 threads unlocked
  • cache: 3mb/16mb (l2/l3)
  • socket type: am4; max temps : 95°c; pci express version : pcie 3.0 x16
  • thermal solution: wraith stealth cooler; base clock:3.2ghz

If you are looking for a processor that wouldn’t be too heavy for your budget and yet works perfectly well for RandomX, then this one is probably the right choice for you. This processor is a 6 core 12 thread processor has the ability to mine Moneros at around 3285 hashes per second. Don’t let the price of this processor fool you, because it’s a really speedy one that you don’t want to miss out on if you’re looking for a good CPU for RandomX. 

4. AMD Ryzen 5 3600X 6-Core Unlocked Desktop Processor

AMD Ryzen 5 3600X Processor With Wraith Spire Cooler
Product Highlights:
  • the world's most advanced processor in the desktop pc gaming segment
  • can deliver ultra-fast 100+ fps performance in the world's most popular games system memory specification 3200 mhz
  • 6 cores and 12 processing threads bundled with the powerful amd wraith spire cooler
  • 4 4 ghz max boost unlocked for overclocking 35 mb of game cache ddr 3200 support
  • for the advanced socket am4 platform can support pcie 4 0 on x570 motherboards

This processor, which is marketed as the “world’s most advanced process in the desktop PC gaming segment” does not disappoint. This beast of a processor is one of the fastest ones you can get, and it is even bundled with the impressive high-performance AMD Wraith Spire cooler that works very quietly. Despite its efficiency, it’s also relatively cheaper in comparison to other good CPUs in the market. 


Listed here are a few of the best CPUs that you can use for RandomX. All of the CPUs listed here are processors made by AMD. Yes, AMD processors are cheaper than their competitors but do not think that it is a low-quality processor just because it costs less. Actually, AMD processors are actually just as great as the most expensive ones out there--not just for cryptocurrency mining but all other computing tasks in general--if not better. If you are on a tight budget, AMD processors are definitely a great choice. Aside from the brand, other factors you must consider when buying a CPU for RandomX is the price, the tasks you will do, and motherboard support. If you want to look for other CPUs aside from the ones listed here, look for something that meets the ideal CPU specification for CPUs to be used for RandomX. As long as it fits the criteria, you’re good to go.
