Will your GPU profit?

📊 Model inputs — these are assumptions, not measurements

Every figure below is an input we chose, not a number this pool has observed. We have not yet run a GPU long enough to measure any of them. Treat the output of this calculator as a model, and check each input against your own costs before you rent anything.

• PRL mining yield: assumed ~$0.50 per H100-hour. Not measured. Depends on live difficulty and PRL price, both volatile.
• H100 operating cost: assumed ~$2.00/hr. Sanity-checked against spot rentals on 2026-08-10, where H100 NVL ranged $2.12–$3.33/hr.
• Inference gross: assumed ~$6.00 per H100-hour. Not measured, and not derived. It presumes both a model mix and a level of paid customer traffic that the inference tier does not have today.
• Total surplus: ~$4.50/hr is simply the three figures above combined. It inherits every assumption in them and is not an observed margin.
• Consumer GPUs (3090/4090/5090) mine only — no inference revenue tier. The Pearl inference kernel is compiled for sm90 (H100/H200) only.
• Enterprise GPUs (H100/H200) are the only hardware the inference tier supports.

What we have actually measured, on an H100 NVL on 2026-08-10: the Pearl vLLM miner served 6,958 inference requests at 445 tokens/sec aggregate with the mining kernel active on all 80 layers. We have not yet measured PRL earned per GPU-hour — at current network difficulty a single card solo-mining would wait months for one block, so that number requires the pool share layer we are still building. We will publish it here when it is measured, and not before.
