How to Mine Cryptocurrency with GPU — Wattcoin Guide

May 31, 2026  —  6 min read

Before Proof-of-Energy, GPU mining was a battle of memory bandwidth and shading units. Ethereum required ~4 GB of VRAM. Ravencoin needed KawPow. Every algorithm locked out certain hardware. Wattcoin changes the game entirely — any GPU works, and every GPU pays the same energy cost per coin.

How GPU Mining Works on Wattcoin

Proof-of-Energy exercises the GPU through a native DirectX compute shader workload. The miner dispatches DirectX compute shaders (D3D11/D3D12) that run a verifiable floating-point vector math loop across the GPU's compute units at a configurable load level. GPU proof hashes are generated via a deterministic integer XOR-shift compute shader. The protocol estimates your energy contribution from your GPU's thermal design power (TDP) and the configured duty cycle:

Energy (Wh) = GPU TDP (W) × Load (%) × Time (h)
// Same formula as CPU — hardware only affects speed, not cost

A 300W RTX 4090 and a 150W desktop GPU pay the same 20 kWh per WTC in Tier 1. The RTX 4090 simply finishes the work faster. Speed scales with shader count and clock speed; cost scales only with watt-hours consumed.

GPU vs CPU on Wattcoin

CPU Miner GPU Miner
Typical power draw 15–150 W 75–450 W
Workload type Integer hashing Compute shaders
Energy per WTC (Tier 1) 20 kWh 20 kWh
Mining speed Baseline 2–5x faster
Best for Always-on, low-power Dedicated mining, faster rewards

Step-by-Step Guide

  1. Download the Wattcoin Miner
    Get the Windows installer from wattcoin.ee. The miner detects all compatible GPUs automatically — no driver hacks, no CUDA toolkits, no configuration files.
  2. GPUs Detected Automatically
    Every GPU in your system — NVIDIA, AMD, or Intel Arc — is detected automatically. Multiple GPUs are supported and their energy contributions are summed.
  3. Set Load and Start
    Choose a GPU load percentage. 50–70% is recommended if you also use your display. The app caps load at ~85% maximum. Start lower (~20%) and increase gradually so the algorithm calibrates properly. Click Start Mining.
  4. Earn Every Block
    Your reward is proportional to your verified energy — paid every block, every time. No pools, no luck, no winners and losers.
  5. Combine with CPU or RAM
    The miner can run CPU integer hashing + GPU compute shaders + memory stride walks simultaneously. All energy contributions are summed for a larger share of the block reward.

What GPUs Work?

Any dedicated GPU with shading units. That includes every modern graphics card from NVIDIA (GTX 900 series through RTX 50 series), AMD (RX 400 through RX 9000 series), and Intel Arc.

Tips for GPU Mining

  • Watch your thermals. GPU shading loads generate heat. Keep junction temperatures below 95°C. The miner throttles automatically if limits are exceeded.
  • Multi-GPU scaling. Every additional GPU adds its energy contribution. A 4x RTX 4090 rig at ~85% load contributes ~1530W — the highest possible energy share outside of server deployments.
  • Ramp up gradually. Start at ~20% load for the first hour so the algorithm calibrates to your specific GPU, then increase in 10% steps every 30 minutes up to your target load.
  • Hybrid mining. Run GPU compute shaders alongside CPU hashing and memory walks for maximum verified energy per machine.
