Looks like Bitcoin GPU mining is making a comeback, in a way

So, a buddy of mine just reached out to share this new method for GPU mining Bitcoin that's popping up. Honestly, I'm a bit confused about how it works, since I've always been a fan of using 10 GPUs on one motherboard with risers for better cooling. This setup could be a big deal for those of us who don’t have access to 240V power at home. I’m running on 48V solar power myself, so this seems like a solid option for me. Check out this Magic Miner Bg02. There are installation videos on YouTube, and I’ve heard some folks are already using it. It runs at 150W to achieve 7TH, which sounds pretty good. If you stack ten of these, that’s 1500W for 70TH. What do you all think about this?

It's energy efficiency isn't that good, even when compared with ASIC aimed for solo/hobbyist miner. For example, Bitaxe Gamma 601 (released middle 2024) use 17W for 1.2TH/s.

Few things are wrong here 😬 this GPU shouldn't cost more than @$200 each I like the idea of GPU like mining but the price and efficiency isn't a good idea, this GPU miner cost $405 or a bit more, to get to the 70th that you claimed to be good idea you will spend $4,000+ I can buy a new Avalon Q that has 90TH/s with $1962 right now and it consumes only 1647watt, those 10 GPUs will take 1500watt and you are getting 70th, do the math yourself, it is not that great. If your so called efficiency is why you talk greater about this GPU miner then this Avalon Q got your back, you can go Eco Mode with this miner and get 54TH using just 843watts. You complained about you having 48V solar setup, this device and most home miners supports 110-240V, a household circuit of 20amps or more will handle these miners. I don't see anything that's better than this miner right now in the leagues of all other home miners.

I also remembered this Asic https://www.asicminervalue.com/ru/miners/canaan/avalon-q If you want to do lottery mining now, you need at least 90-100Th/s. I don't understand such a high price for 7Th/s. An original gift.

I have a different issue. no videos of it mining to a pool. Ie would it mine to say viabtc. or must I mine it to a 'special' pool a big red flag. I run this unit    two YouTube videos the video has an error as the psu being used can do 100 to 250 volts https://youtu.be/xMKlp8RenCw mentions proper voltage range for psu.  This unit clocks well to the hashrate of 35th https://youtu.be/7f3ov4JnzXA it does 35th  I can sell you 2 of them for 2000 and you will burn about 1500 watts lok at the video it shows one of them is 757 watts. I can do black or blue.

Those are NOT by any stretch of the imagination "GPU's". They are ASIC-based miners in cases that for whatever reason use a GPU-style of footprint. Stupidest idea ever....

Acknowledged, thanks.

well not sure it is stupid but it is costly. I can easily match it for 2000 bucks not 4000 bucks  plus a case. and I can build more efficient for more money. for 4000 I could do 2 units using 1 s21 pro board each you get 60+ 60th =120th and pull  800 watts a unit 1600 watts total

I dunno from my perspective if they could leverage all 75W of the PCI-e port and deliver a ton more hashrate to match the bitaxe and other asics these could be a brilliant idea.

Looking at mineshop website mentioned by OP, the 6th image shows it has PCI power slot and connected to computer PSU. So the actual cost to run those miner is higher than some people expect.

Great review from Red Panda Mining WHAT THE... A "GPU" BITCOIN MINER?! https://www.youtube.com/watch?v=at9flvmA0xc&ab_channel=RedPandaMining I don't understand why this device has a GPU connector? It doesn't make sense. Why use additional equipment if it is not needed? Manufacturers have outdone themselves.

IMO the GPU/PCIe connector primarily used to attract some hype/attention, which is somewhat successful. Aside from what you said, i doubt there are many new PSU that have lots of PCIe power cable since GPU mining hype passed many years. But at least the video showed you can choose connect to any pool (that use stratum).

Here's another review from Apexto Mining: https://youtu.be/9Q5kmjfHaVE?feature=shared

Is this a review? It's very short and just tells us a simple how-to to run and use the device. No analysis on energy consumption, sound, etc. There's an estimate of earnings per week, but the numbers are just thrown out there with no details at all. I think that's a low bar for a review, more like an ad for the mining pool tbh. CMIIW.

Why do we need a review of a $400, 150W, 7TH hashrate device A good gift for an IT specialist, but nothing more. Red Panda Mining explained everything in detail, I personally have nothing to add. Avalon Q with 90 TH/s in my country already costs 1570 dollars.

you need to mount them you could do that on https://www.amazon.com/BTBcoin-010S-PCI-Express-Capacitors-Ethereum/dp/B09JSBXG58/ref=dp_prsubs_d_sccl_3/144-6746789-5041910? then screw them into a wooded board you do not need to do any power to the riser. cost 40 for 6 of them you need to have eth cables 1 per miner. say 1 dollar a cable cost 23 dollars https://www.amazon.com/Ethernet-Cable-Network-Patch-Internet/dp/B08LTFZNFD/ref=sr_1_4? you need an eth switch cost 20 https://www.amazon.com/TP-Link-Gigabit-Ethernet-Network-Switch/dp/B00A121WN6/ref=sr_1_3? you need a psu https://www.amazon.com/Bitmain-Antminer-Supply-APW7-Connectors/dp/B07FG81F7H/ref=sr_1_1? cost 72 dollars you now can do six units  at about 42th cost for them is 6x400=2,400 23+20+40+72=155 so add 2400+155=2,555  for 42th you need a pc to get into the guy or buy this I can sell it for $1000.   46 th 890 watts at the kwatt meter that is  19.3 watts a th on a k-watt meter you can lower it if you want but 46th is top speed with the bitmain psu it only need 1 eth cable the newer model has a t21 board in it.

Has anyone in the history of Bitcoin considered FPGA to mine Bitcoin? I wanted to know if it would be something viable.

yes it has been done and no it is no longer efficient.

It was the interim step between GPU's and ASICS. They actually pretty much set in stone the logical configuration of the gazillions of gates used in all ASCIC's for hashing SHA256. That *IS* after all, what FPGA's are mainly designed to do - be test beds for logic circuits to later be implemented in ASIC's. And no, even today they cannot compete in speed or efficiency even when compared with even 1st generations of ASIC's.

It seems exaggerated. The manufacturer's idea is to install this machine on an office computer? So it can work and mine?? It's a waste of time
