Frequently Asked Questions
Is CPU mining still worth it in 2026?
At $0.07/kWh electricity, most consumer CPUs barely break even or lose a few cents per day. Server CPUs (EPYC, Xeon) with large L3 cache can earn $2–$5/day but take 2–3 years to pay back the hardware. Profitability depends mostly on electricity rate and used-market hardware price.
Which CPU is the most profitable for mining?
Without considering electricity, flagship multi-core CPUs with large L3 cache lead (Ryzen 9 7950X, EPYC, Threadripper). Once electricity is included, used-market server CPUs from previous generations often have the best $/W efficiency. The current ranking is in the table on the home page.
How much can you actually earn from CPU mining?
Realistically, $0.10–$1/day on a consumer CPU at $0.07/kWh. Server EPYC builds — up to $5/day. These figures already include pool fee (1%) and stale share losses (0.5%), but not hardware wear or downtime.
What algorithm should you mine on a CPU?
RandomX is the dominant CPU algorithm — designed to be ASIC- and GPU-resistant. It powers Monero, Zephyr, Salvium and other forks. Wownero uses a smaller variant (RandomWOW). Other CPU algorithms (AstroBWT, GhostRider) are either outdated or have liquidity too low for serious mining.
Does a CPU mining rig pay back?
It depends on electricity rate and used-market hardware price. At $0.07/kWh a used Ryzen 5 build pays back in ~1–2 years; a used EPYC server build in 2–3 years. If net profit is negative — payback never happens. Per-CPU breakdown is in the table.
