X user GOK has shared photos of a massive red graphics card featuring four Polaris GPUs on a single PCB, jokingly asking if it is the largest PCIe graphics card in the world. The four GPUs are arranged in a 2x2 layout, each surrounded by eight GDDR5 memory chips, totaling 32 GB of memory across the board. A sticker on the card identifies it as a quad RX 470, which would equate to 8,192 stream processors. The card is powered by four 8-pin connectors and features only a single HDMI output. Photos show the card is significantly larger than a standard motherboard.
While the PCB bears an AMD logo and a 'DYII-XQ570 V1.0' marking, GOK notes the card lacks a board OPN and the marking does not match AMD's official format. He suggests small Chinese factories often use the AMD logo on their own designs. The PCIe switch is identified as a PI7C9X2G, a PCIe 2.0 component, leading GOK to believe the card was manufactured for cryptocurrency mining. He has not tested it yet due to a lack of a heatsink. Multi-GPU Polaris mining boards are not new, as Sapphire released a dual RX 570 mining card with 16 GB in 2021.
