There are a bunch of credible leaks all pointing towards Valve releasing a Nintendo switch style portable gaming PC for playing your Steam games on the go. In this video I discuss everything we know so far. It seems like it is codenamed "SteamPal" and the controllers might be called "Neptune". It might be targeted for Q4 2021 with an AMD APU called "Aerith" or "Van Goh" said to be powered by Zen2 core architecture and Navi2 (RDNA2) integrated graphics at 9W. Quadcore with SMT. Possibly $399 target price and 8/9 inch screen.
It would be interesting to see an Handheld PC made by Valve
