ASIC vs GPU vs CPU: three ways to hash
Hardware families trade flexibility for efficiency. ASICs do one algorithm brutally fast, GPUs cover many algorithms decently, CPUs are everywhere but slow. Which one makes sense depends on which chains you want to serve.

01
The three families
| ASIC | GPU | CPU | |
|---|---|---|---|
| What it is | Single-algorithm chip built for one hash function | General-purpose graphics card (memory-heavy hashing) | Your computer's processor |
| Efficiency | Highest — purpose-built gates | Middle — flexible but carries graphics silicon | Lowest per watt |
| Flexibility | None — algo changes brick it | High — flash a new miner, mine a new coin | High — anything with a CPU miner |
| Typical coins | Bitcoin (SHA-256), Litecoin (scrypt ASICs) | GPU-chain algos (pearlhash, kawpow, progpow family) | RandomX coins, merged/solo lotteries |
| Second-hand risk | Dies with its algorithm | Resells into gaming/AI demand | It was already in your PC |
The trade is efficiency vs optionality. An ASIC wins its one algorithm by orders of magnitude and is worthless the day that algorithm dies. A GPU earns less per watt on any single algo but can rotate between chains when difficulty or price moves — the core strategy for small-network mining.

Where each fits a small miner
- ASIC: you believe in one established algorithm and have cheap power; you accept resale risk.
- GPU: you want to rotate across the smaller PoW chains — this is most of the pow.family universe.
- CPU: mine alongside GPU work (dual mining), chase solo-lottery coins, or use the machine you already own before buying anything.
