A mini PC with the latest AMD RDNA3 SoC at much higher TDP would give you an even better docked performance at an similar to lower cost.

• Unisoc, GCT, Sequans, ASR Micro, Sony Semiconductor.

• Huawei

Higher TDP in docked mode using eGPU.

It will not be a general Steam OS, but a device and partner specific.

eGPU support only.

It will come with SD2, including a new dock with integrated AMD eGPU and a “docked operation” mode for the CPU. There will be a new connector between SD and dock.

For SD1 the CPU limitation and thermal design is not in favour of eGPUs. See ETA prime test on YT e.g.
