Valve Steam Machine Review: GPU & CPU Benchmarks, SteamOS Test, Thermals, Noise, and Price

The Valve Steam Machine delivers RX 6600 or RTX 3060 level performance in GPU-bound games due to hard 110W GPU and 30W CPU power limits, stays quiet with solid thermals, but carries a price premium over DIY builds and includes SteamOS quirks.
