HUGE 4-chip AMD GPU spotted with 32GB of VRAM

Is this the world’s largest PCIe graphics card?

One of the world’s largest PCIe graphics cards has been discovered online: a colossal 4-chip AMD Radeon graphics card with 32GB of total VRAM. This GPU looks like a relic from the GPU cryptocurrency mining boom, a PCIe card that brings together four AMD Radeon RX 470 chips.

A Twitter/X user named GOK discovered this huge graphics card without an attached heatsink. All four GPUs connect over an 8x PCIe interface, with each GPU using two PCIe lanes. Each GPU appears to be powered by an 8-pin PCIe power connector, allowing the GPU to draw up to a total of 600 watts of power (in addition to PCIe power).

While the purpose of this GPU is unknown, it has a single display connector, has limited PCIe connectivity, and has 8GB of memory on each GPU. This configuration appears optimal for cryptocurrency mining. Other workloads would benefit from increased PCIe or display connectivity. Two of these massive GPUs could likely connect to an ATX motherboard with two PCIe x8 lanes. This configuration would deliver strong cryptomining performance in a relatively small space.

Is this an unreleased AMD product?

Given the lack of information about this GPU online, this product was likely never released. Sadly, this GPU is practically useless today. Its lack of a heatsink makes it challenging to use. Furthermore, AMD’s RX 470 is now ten years old, and it wasn’t high-end at launch. If this GPU still functions, it is unlikely to be useful for many modern applications.

The AMD logo on this GPU’s PCB implies that AMD designed this graphics card. In other words, this GPU could be an AMD prototype. This could explain why this GPU lacks a heatsink. No other branding is present on the PCB.
