5e9 * 220 / 3600 / 24 implies they are using 12 million cpu cores continuously? That seems nearly implausible, but perhaps it's true?

- hijodelsol 4y agoI immediately did the same calculation, the climate impact per user also seems non-negligible. Doing some back of the envelope maths, 20W per core server power consumption equals 240.000kWh per hour. At 500g CO2eq/kWh this gives us roughly a billion kilograms of CO2eqs per year. At approx 300M MAUs this is roughly 3.5kg/user/year. Not completely off the charts but still important, reducing the time to 120 CPU seconds per execution would have the similar impact as 300M people not traveling 10-15km by car. Energy costs per user is also interesting, if at all close, at 0.25c per kWh the power consumption cost per user would be greater than 5$ per year.
