Monero proof of work deploys RandomX, a CPU-optimized algorithm launched October 2019 Monero.org. RandomX generates hashes via random instructions on a 2 GiB dataset, 16,384 reads per hash, and 256 MiB cache [RandomX GitHub README].
XMR trades at $404.24 USD, up 3.0% with $7.5B market cap CoinGecko, October 10, 2024.
RandomX Core Parameters
RandomX dataset totals 2,147,483,648 base bytes plus 33,554,368 extra bytes, exceeding 2 GiB. Miners read 64-byte items 16,384 times per hash [RandomX GitHub README].
A 256 MiB cache seeds computations. Keys update every 2048 blocks (2.8 days), with 64-block delay [RandomX GitHub README]. Design resists ASICs through massive random memory access.
PCs excel as RandomX mimics Argon2d but scales for network consensus. Virtual machines execute random code, favoring cache-efficient CPUs over GPUs [Alcazar Security blog, 2023].
Dataset Demands on PC Mining Hardware
The 2 GiB dataset demands 4-8 GB RAM per thread. Ryzen 9 9950X (16 cores, 170W TDP) manages multiple threads via 64 MB L3 cache and 100 GB/s memory bandwidth AMD datasheet.
RandomX quadruples CryptoNight's memory requirements, from hundreds of MiB to 2 GiB. This shift democratized mining since 2019 [Alcazar Security blog].
Pair with 32 GB DDR5-6000 kits (e.g., Corsair Vengeance, $150 USD). Top CPUs consume under 200W TDP, surpassing GPU mining's 300W+ per card XMRig benchmarks, v6.21.

Why CPUs Beat GPUs and ASICs
RandomX executes random instructions on the dataset, evading GPU parallelism. GPUs dominate fixed tasks like Ethash but struggle with branching XMRig benchmarks.
Ryzen Threadripper 7980X achieves 20-30 KH/s. RTX 5090 GPUs reach only 5-10 KH/s XMRig GitHub, v6.21. CPUs deliver 0.1-0.15 KH/s per watt.
Air coolers like Noctua NH-D15 suffice ($110 USD). No liquid cooling required. This setup yields 2.5x better efficiency than NVIDIA GPUs XMRig benchmarks.
Optimal PC Builds for Monero Proof of Work
Assemble on AM5 platform: Ryzen 9 9950X ($650 USD), 64 GB DDR5-6000 ($250 USD), ASUS ROG Crosshair X870E ($500 USD), plus NVMe SSD. Total rig costs $1,500-2,500 USD for 40-60 KH/s.
72-second blocks reward consistent hash rates. Low-latency DDR5 accelerates 64-byte reads. Bitcoin SHA-256 rigs exceed $5,000 USD for similar output ASIC Miner Value index.
