@brandon I don't /think/ I misreckoned, for what it's worth.
While it's a lot in proportion, 38g/kwh works out to an extra 2.2g/h for the ryzen.
According to this https://data.worldbank.org/indicator/en.atm.co2e.pc and some math, the average co2 output for a person is 569g/h, so a ryzen is ~0.03% of that.
Which I'm hesitant to draw any conclusion based on until I were to measure what % of the daily average other differences in choice could make.
