A leaked photo of a huge AMD graphics card comes up and it features one single PCB board with four GPU packages. The downside of this prototype is that it doesn't stick to standard constraints in PC building because it's bigger in size than a full sized motherboard. This is an engineering sample and not something that you can buy at retail. Something for enthusiasts/builders to know!
Leaked engineering sample packs 32 GB VRAM on a board larger than a motherboard
The board seems to have four Radeon RX 470 GPUs. It's 2×2 arrangement, but we assume that each GPU package will have 8GB of GDDR5 video memory. So, that's 32GB of VRAM on a single PCB. The card interfaces with your system through a regular PCIe connection.
Specifications
- GPU Configuration: Quad Radeon RX 470 (2×2 layout)
- Total VRAM: 32 GB GDDR5 (8 GB per GPU)
- Interface: PCIe
- Physical Size: Larger than a standard motherboard
When we take a closer look, we see that there's a lot of power circuitry. Moreover, we see that the GPU dies are exposed and don't have heat spreaders. The photos were leaked on X on November 3rd 2026 by a leaker named GOKForFree. According to the leaker, this could be the largest PCIe graphics card in the world.
We don't know the use case of this hardware. It could be for mining or HPC. There's no official retail AMD branding on the board.
So, yes, it's a prototype or engineering sample. Very interesting leak and we get to see the density of multi-GPUs, which is higher than what we have today at consumer level.
