Massive Four-GPU RX 470 Card Surfaces, Probably Built for Crypto Miners

X user GOK has shared photos of a huge red graphics card that carries four Polaris GPUs on a single PCB, jokingly asking whether it might be the biggest PCIe graphics card in the world. The four GPUs sit in a 2x2 layout, and each one appears to be surrounded by eight GDDR5 memory chips, which would mean 8 GB per GPU and a gigantic 32 GB across the board. According to GOK, a sticker on the card identifies it as a quad RX 470, which would work out to 8,192 stream processors in total. Feeding all of that are four 8-pin power connectors, while the only display output is a single HDMI port. A second photo shows the card lying next to a motherboard, and it's noticeably bigger than the board itself.
The PCB does carry an AMD logo next to a "DYII-XQ570 V1.0" marking, but it looks like AMD may not have built this one. GOK pointed out that the card has no board OPN (part number) and that the marking doesn't follow AMD's official format, adding that small factories in China sometimes put the AMD logo on their own designs. He also identified the PCIe switch as a PI7C9X2G, a PCIe 2.0 part, and thinks the card was likely made by one of those factories for crypto miners. He hasn't tested it yet, since he doesn't have a heatsink for it. Multi-GPU Polaris mining boards aren't new either, as Sapphire had a dual RX 570 mining card with 16 GB and a single HDMI port back in 2021.
