REFERENCE COMPARISON
Compare the 234 TH/s Pro and 270 TH/s XP. Check the gain in hashrate against wall power and your own purchase quotes; efficiency alone does not determine payback.

234 TH/s reference from the multi-bin guide. The 220 and 245 TH/s variants have different power ratings.
The reference uses 3,510.0 W. The table and mathematical differences above use your selected tariff, so all displayed comparison costs update together.
270 TH/s nominal specification at 25°C. Real wall power varies with temperature and firmware.
The reference uses 3,645.0 W. The table and mathematical differences above use your selected tariff, so all displayed comparison costs update together.
Lower J/TH means less electrical energy per unit of hashing work. It does not account for purchase price, installation, noise, cooling infrastructure or resale value. Enter comparable hardware quotes and inspect the exact bin before using an estimate in a budget.
Turn wall power and your electricity tariff into daily, monthly and yearly running costs.
