Remember when some of ya'll said that it was too early to decide whether AMD was "back"?

How about now:

PS: Not an "in your face", it's a serious question

Oh heck, the productivity test poor things! I know where I'm putting my money in my next build.

@brandon not silly response:

Oh wow that seems like a big step toward making not-just-fan-based-cooling more of a default in desktops.

@emsenn the on-mobo cooling seems to be fan-based though, did I miss what you intended to say?

@brandon Oh, no, I misassumed and thought it meant like, it needed a place to hook into liquid cooling from the mobo

@emsenn Oh no, there will literally be fans ON the mobo cooling the mobo chipset

@brandon interesting!

I wonder what the co2 output of using a computer with all this for text editing for an hour is, versus something like an RPi.

(I know this CAN do much more, I'm curious about its footprint when it's doing nominal work.)


Assumed numbers:

RPi 4 Max = 6W
Ryzen 7 Idle = 70W (including other parts of computer)

Calculated per hour co2 output:
Vermont: 0.003g co2/hour
Wyoming: 0.925g co2/hour

In vermont:

RPi4 = 0.018g/h co2 output
Ryzen = 0.21g/h
Delta = 0.192g/h

In Wyoming:

Rpi4 = 5.55g/h
Ryzen = 64.75g/h
Delta = 59.2g/h

You can see why I said "it depends" :P

Source for co2 output numbers used in calculations:

Conclusion: Rpi4 produces 8% of the co2 the ryzen 7 PC might

@brandon I think you're overcomplicating it by considering power plant differences yourself instead of working with a known average. The question is "what is the difference in co2 output between the ryzen and Rpi." The math can be simple, (x-y)*(z) where x is the kw/h of the ryzen, y the kw/h of the RPi, and z our average co2/kw*:

(0.07-0.006)*512 = 32.78g/kwh difference in output.

* there's debate about what "our" average is, I went for the U.S.


@emsenn Did you mean to say 32.78g/kwh or per watt-hour?

@brandon I believe per kwh but I might've misreckoned, arithmetic is not my strong suit.

@emsenn ugh fuck it :P We know the difference is "a lot" :P

@emsenn If you would have said watt-hours (which seems to make more sense to me considering my calculations) I would have said the average of the two deltas results in 29.7g/h which would have been pretty close to your 32.78

@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 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.

@brandon It really is some bullshit how much just... slogging through basic math it takes to be reasonable; the results for these questions should honestly be easily searchable online.
