Efficiency Class Comparison Report
Side-by-side benchmarking of two or more rigs at your target hash rate, with a written class assignment and power-cost projection for Korean electricity tariffs.

Hash Rate Meets Honest Measurement
We review and compare mining rigs at 0.05 PH/s and above, placing each unit into a defined efficiency class so South Korean operators can judge power draw against real output.

What We Measure
Every assessment covers wattage per terahash, thermal behaviour under sustained load, firmware variance, and how the unit ranks within our five-tier efficiency classification.
Fleet Benchmark Session
Our technicians visit your facility in Gyeonggi or neighbouring provinces to run controlled load tests across an existing deployment.

Pre-Acquisition Rig Audit
Before you commit capital to new hardware, we verify manufacturer claims against our reference rigs and flag units that underperform their rated class.

Operators who used our reports before expanding capacity or replacing ageing units.
The comparison report on our two Antminer S19 variants saved us from ordering twelve units that would have landed in Class D. The watt-per-TH figures matched what we saw after a week of operation, though I wish the thermal section had covered our specific rack airflow setup.— Min-jun Park, 1.2 PH/s facility, Hwaseong
We brought Cypresshub in before a second-hand lot purchase. They caught a batch with degraded hash boards that the seller's spec sheet did not mention. Straightforward process, no sales pitch for hardware we did not ask about.— Soo-yeon Han, independent miner, Suwon

Why Joules Per Terahash Matters More Than Sticker Hash Rate
A practical guide to evaluating mining hardware efficiency when Korean electricity tariffs eat into margins faster than hash-rate gains.
Cooling Mistakes We See in Gyeonggi Warehouse Conversions
Repeated airflow and rack-layout errors that push mining rigs into lower efficiency classes than their bench ratings suggest.
