Valve’s highly anticipated Steam Machine is still a while away from an official release. But a new AMD-powered cube from Thunderbolt is already leaning hard into the same living-room PC energy. However, the price is anything but console-like. Thunderbolt has just unveiled its AI Mini Workstation in China after first showing it at CES 2026. The compact cube-shaped PC is powered by one of the most powerful AMD mobile chips, if you have a few thousand dollars to spare.
Steam Machine looks for workstation money
The design is the obvious attention-grabber. Thunderbolt’s machine uses a cube form factor that measures 199 x 199 x 199mm, giving it the kind of compact, console-adjacent look people have been expecting from Valve’s upcoming Steam Machine. But where it really sticks out is with the hardware under the hood. This isn’t your typical casual desktop. The launch configuration includes a whopping 128GB of LPDDR5X RAM and 2TB of PCIe 4.0 storage. The Ryzen AI Max+ 395 powers this system, which brings AMD’s Radeon 8060S integrated GPU.
Users can even allocate up to 96GB of VRAM from system memory. All of this makes the system capable enough for heavy AI workloads, and not just gaming.
Thunderobot is also going big on cooling. The AI Mini Workstation uses a custom liquid-cooling system with a “full-coverage cold plate” designed to keep the Ryzen APU and key components under control during heavy workloads. The company pairs that with a 14-phase power supply, allowing the system to deliver up to 176W of power. There’s a solid selection of ports too, with two USB4 ports, HDMI 2.1, DisplayPort 1.4, multiple USB-A ports, USB-C, 10G Ethernet, 2.5G Ethernet, dual 3.5mm audio ports, Wi-Fi 7, and Bluetooth 5.4.
What’s the catch?
The two issues with this cube-shaped workstation are its price and availability. At nearly $4,000, you’re not looking at a Steam Machine or console alternative. Thunderobot doesn’t have a major global footprint, so a launch outside of China looks unlikely for now.
