Ever wondered what happens when cutting-edge technology meets whimsical design? Enter the Cybertruck Mini-PC, a fusion of the iconic Tesla Cybertruck and a powerful desktop RTX 4090 GPU. David from “David Does Tech Stuff” has taken this eccentric idea from blueprint to reality, and the results are both fascinating and complex.
Imagine packing a heavy-duty GeForce RTX 4090 into a cyber-themed miniature PC. Off the bat, this may sound quirky but feasible. Challenges quickly arise, however. The biggest hurdle revolves around a vital secondary M.2 slot, inconveniently located beneath the model’s “car” frame, making it impossible to attach any storage without significant modifications. Even after drilling, the position of a wheel obstructs this slot, and taking this Cybertruck-apart is no walk in the park.
Determined, David tries a workaround by testing a PCIe adapter for the M.2 WiFi slot. However, here’s the catch: PCIe adapters for M.2 slots usually offer only a two-lane limit (32 Gbps), much slower than alternatives like Thunderbolt 3/4 or OCuLink. This bottleneck keeps the RTX 4090 from operating at its full power potential. Instead of unleashing the beastly 450W TDP, the GPU barely sips energy, drawing only 60W and performing worse than integrated graphics like the Radeon 780M.
But innovation doesn’t dim that easily. David stripped the Cybertruck chassis and employed a naked board with an M.2 to OCuLink connector. Although this setup sacrifices aesthetic appeal, it significantly boosts GPU performance, pushing the power consumption rate up to 400W, nearly unleashing the RTX 4090’s full prowess.
This video by David offers a captivating look at options available to those dealing with systems not primarily designed for external GPUs. Adapters like M.2 and OCulink PCIe open up possibilities, although they come with spatial limitations, especially for laptops or compact Mini-PCs. The Cybertruck Mini-PC is essentially a repurposed laptop motherboard in a niche design package—neither budget-friendly nor particularly practical.
Will there be updates to make external OCuLink integration simpler? Maybe. However, given the mobile Zen4 APU’s constraints, coupling it with an RTX 4090 eGPU might seem excessive, especially with limited PCIe bandwidth as a primary concern. For now, it remains an interesting concept, blending the future of gaming PCs with a twist of automotive innovation.
As the tech world evolves, it’s experiments like these that push the boundaries, showcasing what’s possible and what’s still a dream in progress. Whether or not the Cybertruck PC becomes a mainstream success, it undeniably adds a unique chapter to the saga of unconventional computing.
