So they're trading bandwidth for CPU load at either end. I wonder what the tradeoff is in terms of energy? Would this result in higher CO2 emissions?
- pier25 6y agoOr maybe lower since less data is transmitted?
- Spivak 6y agoMaybe but you're discounting the energy required to send those 99% of pixels over the network. Just because it's not your CPU doesn't mean it's not doing work.
- datameta 6y agoIndeed, in the case of LTE comms and mobile chips the difference in power usage is greater than six orders of magnitude.
