Golden Reviewer is not infallible and not everything he says squares with what other reviewers are saying. The Mandarin speaking reviewers - Geekerwan and Xiaobai's Tech Reviews - give accounts that are mainly in line with what Golden Reviewer has to say on performance but paint a very different picture of energy efficiency of CPU cores and GPU. Anandtech, too, has presented a preliminary report on the Snapdragon 8 Gen 1. That report, like the reports by the already mentioned reviewers, again presents a picture that is at odds (in some ways) to Golden Reviewer's particular take on that SoC.
Personally, I will be eagerly awaiting the more extended report from Anandtech on the premium Android SoCs coming in 2022. I don't doubt that these SoCs will run hot, though. SoCs based on ARM licensed IP have been at the power consumption limit since early 2019 and SoC manufacturers just keep pushing power requirements up (with new 'non-core' processing unit logic) without any corresponding power savings on the CPU or GPU. Samsung's silicon process nodes have also underperformed. Problematic thermals and power consumption was always going to be the likely result.
Apple, for its part, even as it pushes forward on performance seems to get notable gains in energy efficiency from generation to generation. Apple's A series processors, so far, have kept thermals under control but these mobile SoCs, once again, push power consumption to the limit for a small form factor device.
