SAMA X 380 ASIC Miner Overview

Minsama has just revealed the SAMA X 380 ASIC miner, packing a powerful 377 TH/s, top-notch air cooling, and great efficiency at just 7 J/TH. If you're interested, check out the video release that showcases the cool features and tech behind this new machine. - Hashrate: 377 TH - Energy efficiency: 7 J/TH - Power usage: 2750 W - Cost: $12,800 - Noise level: 37 dBA Just a heads up, this might turn out to be a scam, so hold off on any purchases until there's more solid info available.

At 7J/T I highly doubt  - like 99.999% against- it exists. That level of efficiency is simply not possible even if they use 3nm node chips (which no one is) and they say they are 4nm chips. Throw in it being air cooled - fans pull power - and its SPL of 37db, well, not gonna happen. The diamond heat spreader is nothing new. Diamond heat spreaders have been used for decades where their cost justifies it. The idea is to take heat from a small surface area - in this case the top of a chip - and spread it out over a larger area (the heat sink) to be dissipated. The advantage comes from it being spread out and feeding the entire surface area of the heat sink vs being concentrated in the center of a heat sink and the sink itself carrying the heat to its edges.

It would be more believable if they actually showed the device's UI mining to any known pool for actual power and hashrate validation.  Without that meh..
