What is RandomX?
RandomX is a memory-hard proof-of-work algorithm developed specifically for Monero to neutralize the dominance of specialized application-specific integrated circuits (ASICs) and high-end GPU farms.
It achieves this by running randomized code sequences generated on the fly inside a specialized virtual machine. Because modern consumer desktop CPUs feature out-of-order execution, advanced branch predictors, and ultra-fast L3 caches, commodity processors are the most cost-effective hardware for RandomX.
Technical Requirements:
- Minimum 2MB of L3 cache per active mining thread.
- Hardware-accelerated AES instructions (AES-NI).
- Dual-channel or quad-channel DDR4/DDR5 system memory with tight latency timings.
- Operating system support for 1GB Large Pages.
Mining Considerations & Thermal Risks
Key operational factors to keep in mind when running RandomX on your home or office computer.
High CPU package wattage (65W – 200W+) under 100% thread load requires proper thermal paste and heatsink capability. Laptops with limited cooling may experience aggressive thermal throttling.
Standard pool fees average 0.5% – 1.0% PPLNS. Typical payout thresholds range from 0.003 XMR to 0.1 XMR.
High spot liquidity globally. Source baseline verified as of 2026-10-03 via Monero RandomX specification repository.
