Raspberry Pi Hacker Moves Closer to Working External GPU

Posted on



After almost two years work, inveterate Raspberry Pi tinkerer and friend of the Tom’s Hardware Pi Cast Jeff Geerling has succeeded in his goal of getting an external GPU to work on Compute Module 4’s via the carrier board’s PCIe slot. 

Naturally, Geerling is kind of happy about the development, which comes as a result of the combined efforts of dozens of people exploring, as he puts it, “the dark, dusty corners of the BCM2711”. That’s the Broadcom Arm chipset powering the Compute Module 4 and Raspberry Pi 4, which already has a perfectly good GPU on board. Previous experiments have seen an ancient SM750 GPU flicker into life, but what can this breakthrough bring to the Pi?
