An enormous graphics card pictured online carries four Polaris GPU packages on a single red PCB, with a reported 32GB of GDDR5 memory. The unusual board has been linked to the Radeon RX 470, but its exact chips, intended use and manufacturer remain unconfirmed. Its layout points to an experimental or mining-focused design—not a typical gaming card.
Key takeaways
The card is an intriguing piece of hardware history, but there is no indication it was a retail product.
- Four GPUs are believed to be Polaris chips in the RX 470 class.
- The memory layout suggests 8GB per GPU, or 32GB total, though that capacity has not been verified.
- Four 8-pin power connectors, one HDMI output and an x8 PCIe connection are visible or reported.
- Crypto mining is one theory; an engineering test board is another.
Four GPUs share one oversized PCB
Photos shared online show the bare board with four GPU packages arranged in a 2×2 grid. GDDR5 chips surround each package, alongside extensive power-delivery components. The card is large enough to dwarf a motherboard placed behind it, and has four 8-pin power connectors and a single HDMI output.
Each RX 470-class GPU has 2,048 stream processors and a 256-bit memory bus. If that identification is correct, the board would have 8,192 stream processors in total. The apparent memory-chip configuration suggests 8GB for each GPU, but the capacity has not been independently confirmed.
Its purpose and maker remain unclear
The limited display output and PCIe x8 connection are unusual for a gaming card, making cryptocurrency mining a plausible explanation. Polaris GPUs were popular with miners, and a multi-GPU board could reduce the need for separate cards and risers. However, no documentation confirms that this was a mining product; it could instead be a development or validation board.
An AMD logo appears on the PCB, but that alone does not establish that AMD manufactured it. The board’s markings reportedly do not match AMD’s usual part-number format, and the card has not been tested. One report also identifies a PCIe switch chip, but details about how the GPUs communicate, their clocks and the board’s power draw remain unknown.
Not a practical upgrade for PC builders
A reference RX 470 was rated around 120W, suggesting four such GPUs could approach 480W before accounting for memory and conversion losses. The four 8-pin connectors provide substantial power capacity, but cooling four closely packed GPUs would be a major challenge. No cooler is shown, and there is no confirmed information about a working driver setup or system compatibility.
For ThinkComputers readers, the board is more notable as an unusual design experiment than as hardware to seek out. Unlike conventional multi-GPU gaming setups, this prototype offers no verified performance results—and its single HDMI output, unusual size and uncertain software support make it impractical to assess as a consumer graphics card.
