Ethereum Classic uses Ethash — the original Ethereum proof-of-work algorithm. After Ethereum switched to proof-of-stake in 2022, ETC became the primary destination for GPU miners with Ethash hardware. Enter your hash rate and electricity cost below.

Ethereum Classic is the continuation of the original Ethereum blockchain following the 2016 DAO hard fork. When Ethereum transitioned to proof-of-stake in September 2022, Ethereum Classic remained proof-of-work — inheriting the entire GPU mining ecosystem that had been built around Ethash hardware.
ETC is also targeted by purpose-built Ethash ASICs. The Jasminer X4-Q (1040 Mh/s at 480W) and Antminer E9 Pro (3680 Mh/s at 2200W) vastly outperform GPUs on raw hash rate, though GPUs remain competitive in markets with low electricity costs.
Is Ethereum Classic the same as Ethereum?
No. Ethereum (ETH) is now proof-of-stake and cannot be mined. Ethereum Classic (ETC) kept the original proof-of-work chain and Ethash algorithm, and is fully mineable.
What's a good GPU hash rate for ETC?
The RTX 3080 achieves ~98 Mh/s, the RTX 4090 ~132 Mh/s. Mid-range cards like the RTX 3060 Ti (~60 Mh/s) and RX 5700 XT (~54 Mh/s) offer solid efficiency per watt.
Can you still mine ETC with old Ethereum GPUs?
Yes — if your GPU has 4 GB+ VRAM and was mining ETH before the Merge, it works on ETC at the same hash rate. The algorithm is identical.
