Someone is selling a second-hand mining system on eBay. The amazing thing is that it actually uses the AMDAPU processor from the Sony PS5 console, and it has as many as 12 mining cards in parallel. In the past few years, various mining solutions have emerged one after another. Although AMD seems to have done little, it has done a lot secretly, almost all of which have never been made public.
This set uses the BC-250 mining card. It is different from other purely GPU-based solutions such as BC-2330, BC-2235, BC-160, etc. It uses an APU, the same one in Sony PS5.
This card is quite long, with a thick heat sink on the front and a full metal backplate on the back. After taking it off, you can see the familiar PS5 processor, TSMC 6nm process, Zen2 CPU architecture, and integrated 2304 RDNA2 architecture stream processors, with an external 256-bit16GBGDDR6 video memory.
When 12 fast cards are connected in parallel, there are 27648 stream processors and 192GB of video memory.
The power supply is two customized 8-pin interfaces converted to a standard 8-pin interface. The output interfaces are also very complete, including a DP video output, four USBs, and an RJ-45 network port.
It is said that this card was released as early as December 2021, and it should be made of defective leftovers from the PS5 processor production capacity.
The seller also posted a rendering of the operation. Each card is plugged into a USB flash drive and a network cable for remote management. The system power supply is as high as 1200W.
It is said that the hash performance of this kind of card is as high as 610MH/s, and it can mine ETHASH and ETC. In the early days, each card could earn about 2 US dollars per day, but now it is only about 0.2 US dollars.
Just for this, a card costs US$500, which is approximately RMB 3,560.
