Netflix can now serve 100Gbit/s of video (so something like 12,500 individual 4K streams) with an appliance using 100 watts of power. That’s 8 milliwatts for each 4K stream.
Remember that number the next time someone tells you that watching a Netflix show is as bad as driving an SUV or some shit.
@karppinen
That's a statement that requires expansion. The hundred Watts is the power requirement of the server? or just the network interface? And the huge number of gigabytes of video data themselves... the storage of that is in a zero Watt data centre somewhere? I applaud every attempt to reduce our colossal energy demands, but I have to filter everything through my uh-huh server... ;-)
@incredibish the whole server, as far as I can tell, including the local storage on it. The content of course must come from somewhere, but I would expect them to reach pretty good cache rates with these appliances.
So if the hit rate is 99%, for example, the upstream servers could be 100x more energy intensive and still only add another 8 milliwatts to the cost of the stream.
