KHeavyHash and RandomX run through dedicated calculators — Kaspa and Monero aren't tracked by the main WhatToMine feed.
The RTX 3090 launched in September 2020 at $1,499 — making it the first 24 GB GDDR6X consumer card and a favorite of Ethash miners pre-Merge. Post-Merge, it pivoted to Etchash and Kaspa where its memory bandwidth and core count still deliver near-flagship hash rates at noticeably lower power draw than the 4090.
At $0.06–$0.10/kWh, the RTX 3090 stays profitable on KHeavyHash and Etchash. The card's strength is efficiency — 285W tuned is roughly 65W lower than the 4090 at most algorithms, which closes the daily-profit gap on cheap power.
Is the RTX 3090 still good for mining in 2026?
Yes, for coins it can mine without ASIC competition: Ethereum Classic (Etchash), Ravencoin (KawPow), Ergo (Autolykos2). At sub-$0.08/kWh electricity it's still profitable; at $0.15+/kWh margins are tight.
RTX 3090 vs RTX 4090 for mining?
The 4090 hashes ~10% higher on most algorithms but draws more power. On Etchash specifically the 3090 is closer in efficiency. Buy the 4090 for raw output, the 3090 for $/MH at low power rates.
How many watts does the RTX 3090 use mining?
Stock TGP is 350W. Most miners power-limit to 270-290W for the best efficiency curve. Calculator uses 285W by default.
What's the best coin for RTX 3090?
Historically Kaspa (KAS) on KHeavyHash leads, with Ethereum Classic (ETC) on Etchash as the steady second. The live table above ranks today's options.
