The idea of using the PS5’s PCIe M.2 slot to connect an external GPU or accelerator is technically intriguing but impractical due to latency issues, user inconvenience, and the advanced capabilities of modern consoles. While nostalgic hardware expansions inspired curiosity, the consensus is that future improvements will focus more on software and game development rather than external hardware upgrades, though hobbyists may still explore such possibilities.
The discussion begins with the intriguing idea of using the PlayStation 5’s PCIe Gen 4 interface, primarily intended for NVMe SSD storage, to connect an external accelerator or even an additional GPU. This concept draws nostalgic parallels to past console upgrades like the Super FX chip or the Sega 32X, which aimed to extend the lifespan and capabilities of their respective systems. The notion also extends to the potential for the Nintendo Switch 2, speculating whether its USB or cartridge port bandwidth could support similar enhancements. However, the initial excitement is tempered by practical considerations.
A key challenge highlighted is the complexity and inconvenience of requiring users to manually upgrade their consoles. The process would likely be too cumbersome for the average consumer, reducing the appeal of such hardware modifications. Additionally, any external accelerator connected off-chip would introduce significant latency, which could negatively impact gaming performance. Despite these drawbacks, the presence of the PCIe interface does leave room for experimental or hack-driven projects, especially within communities exploring the PS5’s Linux capabilities.
The conversation touches on the possibility of adding features like frame generation through such external hardware, although this would further increase latency. The humorous exaggeration of “10 minutes of latency” underscores the impracticality of such an approach. Nonetheless, there’s a sense of curiosity and enthusiasm for seeing community-driven innovations that push the boundaries of what the console hardware can support, even if such projects remain niche and unofficial.
From a broader perspective, the panelists express skepticism about the necessity or usefulness of external hardware upgrades in modern consoles. Unlike earlier gaming eras where hardware expansions could unlock new functionalities, today’s consoles already possess highly capable and versatile hardware. The focus has shifted towards software and game development to enhance user experience rather than relying on hardware add-ons. This evolution reflects the maturity of current gaming technology and market expectations.
In summary, while the technical possibility of using the PS5’s PCIe M.2 slot for an external GPU or accelerator exists, practical limitations and the advanced nature of contemporary consoles make it an unlikely or unnecessary path. The nostalgia for hardware expansions is acknowledged, but the consensus is that improving software and game quality remains the primary avenue for advancing console gaming. Nonetheless, the idea remains an interesting thought experiment and a potential playground for dedicated hobbyists and hackers.
