MicroBT just dropped their latest WhatsMiner lineup at an Abu Dhabi showcase, and the specs are looking competitive.

They're rolling out a three-tier efficiency structure this time. The flagship tier hits 12.5 J/TH, with mid-range models at 13.5 J/TH and entry-level options at 14.5 J/TH. Each efficiency bracket includes both air-cooled and liquid-cooled variants, giving miners flexibility based on their operational setup and climate conditions.

The strategic tiering approach suggests MicroBT is targeting different segments simultaneously — from large-scale industrial operations prioritizing maximum efficiency to smaller miners watching upfront costs more closely. With hash rate competition intensifying across the Bitcoin mining sector, these efficiency numbers will be crucial for profitability calculations, especially as block rewards continue their programmed decline.
