The RTX 5050 8 GB is 10-20% faster and the Intel 225F is significantly more powerful (a bit harder to get percentage ranges there since there aren't many 225 benchmarks).
The Steam Machine has been known to be roughly a Ryzen 5 3600 + RX 7600 M performance wise for a while and the release benchmarks have confirmed it; given Valve's statements that it would likely cost more than consoles before prices went haywire, I don't think the Steam Machine would ever have been priced competitively.
