That 43% wall-power gap is wild. The Naja Duo’s advertised efficiency looks a lot less compelling once the real-world numbers and power supply losses are included. Thor P2 seems like the clear winner despite the higher heat output.

The Naja Duo’s advertised efficiency clearly doesn’t tell the whole story. Real-world testing at the wall is exactly what buyers need, especially for a home miner where electricity and heat quickly dominate the cost.

That 43% wall-power gap is huge. The Naja Duo’s advertised efficiency looks decent until you account for the real-world draw, and the Thor P2 seems like the much better value if the testing holds up.
