RandomX Mining Hardware

What a RandomX Machine Actually Does for You

Monero never wanted specialised hardware. RandomX, live since 2019, runs best on ordinary processors, and the network had already forked several times to break earlier machines. That is the first thing to understand before you buy, and we would rather say it here than let you find it out later. What exists today is a small class of RandomX machines that beat a rack of servers on space and on power per hash: the Antminer X9 at 1 MH/s and 2,472 W, and the older X5 at 212 kH/s. If you are choosing between the two, the numbers below make the decision for you.

Best Efficiency

2.47

J/kH on the X9 — 2.6× better than the model it replaces

Algorithm

RandomX — CPU-optimised by design, which is why so few machines exist

What You Should Know

Monero has forked to break mining hardware before. Plan a shorter payback than you would on Bitcoin

Top Hashrate

1 MH/s

Roughly what a rack of high-core-count processors delivers, in one box

Model Comparison

Two Machines, and the Gap Between Them Is Not Close

Only two RandomX machines have reached the market. They differ sharply on efficiency and on price, so the comparison is short.

Antminer X9

The current machine and the only one we recommend buying new. 1 MH/s at 2,472 W works out to 2.47 J/kH, and it lists well below the older model. If you want a RandomX machine today, this is it.

Hashrate

1 MH/s

Power

2,472 W

Efficiency

2.47 J/kH

Algorithm

RandomX

Antminer X5

The first RandomX machine, from 2023. At 6.37 J/kH it needs 2.6 times the power per hash while costing roughly twice as much — it is here for operators extending a fleet that already runs these units. Currently sold out; ask us and we will tell you honestly whether waiting makes sense for you.

212 kH/s

Power

1,350 W

RandomX, ASIC Resistance and What It Means for Your Purchase

RandomX was designed to make specialised hardware pointless

RandomX went live in November 2019. It runs a randomly generated program inside a virtual machine and leans on large memory and general-purpose instructions — the things a normal processor already does well and a fixed-function chip does not. The goal was to keep mining reachable for people with ordinary hardware, and it largely held: most Monero hashrate still comes from processors.

The network has broken mining hardware before

In 2018 Monero hard-forked its proof-of-work several times in a row, each time specifically to invalidate machines that had appeared on the previous algorithm. Hardware bought for those forks stopped being competitive within months. This is documented history, not speculation, and it is why we tell buyers to model a shorter payback than they would on SHA-256 hardware.

So why do these machines exist at all?

Because the resistance is economic, not absolute. A purpose-built device still wins on density and on power per hash against a rack of servers. You are not buying a hundredfold advantage the way you would on Bitcoin; you are buying fewer machines, less rack space and a lower power bill for the same hashrate. Whether that trade works depends on what you pay for electricity and floor space.

What we would tell a friend

Buy on today's numbers, not on a five-year projection, and assume your advantage is not permanent. If the machine pays for itself inside a horizon you are comfortable with at your own power price, it is a sound purchase. Everything ships duties paid with full warranty, so at least the landed cost holds no surprises.

Power Decides This

At 2,472 Watts, Your Electricity Price Is the Whole Result

An Antminer X9 draws roughly 59 kWh a day. At $0.30/kWh that is about $530 a month before the machine has earned anything; at $0.06/kWh it is around $106. Nothing else in the calculation moves that far. If your domestic tariff sits at the upper end, hosting is not an upsell — it is the difference between a working position and a losing one.

FAQ

Buying a Monero Miner: Straight Answers

Twenty questions on the hardware, the running cost, the pool and the delivery. If you want the step-by-step side of mining, that lives in our guides.

The Antminer X9. It delivers 1 MH/s at 2,472 W — 2.47 J/kH — while the older model needs 6.37 J/kH and lists at roughly double the price. There is no case in which the older one is the better new purchase. Run your own numbers in the Monero mining calculator before you commit.

Less predictable than Bitcoin hardware, and we will not pretend otherwise. Monero designed RandomX to favour processors, and the network hard-forked several times in 2018 to break earlier machines. Buy on a payback horizon you can live with rather than on a long projection — the reasoning is set out in full in our Monero mining guide.

You can, and most of the network does exactly that — RandomX was built for it. A dedicated machine buys you density and power efficiency, not a categorical advantage: fewer boxes and less rack space for the same hashrate. If you have spare capacity and cheap power, that route is perfectly sensible, and we explain it step by step in our how-to guide.

That depends on the XMR price, network difficulty and above all your power tariff, so any fixed number here would be wrong within a week. Our calculator uses live difficulty and lets you enter your own electricity price, which is the only figure that makes the result meaningful.

Like any 2.5 kW air-cooled machine: around 75 dB, too loud for a room you work in, and hot enough to need real airflow. Plan for a garage, a ventilated basement, or hosting. Our hosting exists largely because most buyers discover this after delivery rather than before.

Possibly, and we would ask you to think it through first. It is the 2023 generation, less than half as efficient and priced above the current one. It makes sense mainly for operators extending a fleet that already runs it. Talk to us and we will tell you plainly whether waiting is worth it in your case.

The machine, its power supply and full manufacturer warranty. Shipping is duties paid worldwide, so the price you see is the landed cost and no bill arrives after delivery. Details are on our shipping page.

BTC, USDT and USDC, or wire and ACH to our US bank account in New York. If you would rather pay in XMR, ask us and we will arrange it for your order.

Any pool that accepts RandomX hashrate from dedicated hardware — and that is worth checking first, because some Monero pools take processor hashrate only. We earn nothing on pools, so we have no reason to push one. The options are compared in our mining guide.

For some operators, yes — Monero has persistent demand as a privacy coin and a mining base that never consolidated into a handful of industrial farms. Whether it works for you is a power-price question first and everything else second. We took the question apart, including the uncomfortable parts, in a separate article.

Yes, on the same terms as our other hardware: our own sites, with power, cooling and uptime in one rate. You can buy and host in a single step, or ship us machines you already own. Hosting details are here.

RandomX leans on large memory and general-purpose instructions, so a general processor keeps most of the advantage and fixed-function silicon gains far less than it does on Bitcoin. That is deliberate, and it is why only two dedicated machines have ever shipped. The background is here: what Monero mining is and how RandomX works.

Most will, but not all: a few Monero pools take processor hashrate only, on principle. The decentralised P2Pool pays straight to your own wallet and is popular for that reason. Check the pool rules before you order, or tell us which pool you have in mind and we will check them with you.

You need an XMR wallet address, because that is where the pool pays. The machine brings its own control interface, so the XMRig software that processor miners run is not needed here — you enter pool address and wallet once, and it works from there.

About 59 kWh a day for the X9, so your tariff decides everything: roughly $18 a day at $0.30/kWh against $3.50 at $0.06/kWh. Put your own price into the calculator and you will see the result that applies to you.

Units in stock leave us within 1–3 business days, and delivery is duties paid worldwide, so customs are settled before it reaches you. Transit time and the countries we serve are listed on our shipping page.

You get the full manufacturer warranty on every new machine. If a unit fails inside that period, write to us with the serial number and we handle the claim for you rather than sending you to the manufacturer. We also keep spare power supplies and control boards for the current model.

A 220–240 V supply able to carry 2,472 W continuously, a stable internet connection, and somewhere that tolerates 75 dB and a steady stream of hot air. Full specifications, including dimensions and weight, are on the Antminer X9 product page.

Yes, and we recommend it. Pick a time for a free call by Zoom or phone, or call us on +1 754 212 3521, and we will go through your power price, your site and your pool before anything is ordered. All the ways to reach us are on our contact page.
