ARM's newest Mali-G78 GPU has been tested alongside the Kirin 9000 on a Huawei Mate 40, and the results look alarming. Although the GPU manages to hit 1 TFLOPS under peak load, the accompanying power consumption can go as high as 14W. Its average power usage seems to be around 9W.

I'll see what AnandTech comes up with. The app itself seems really fishy here, like for example TFLOPS is not a reliable way of measuring a graphics performance of phone chip GPU.
Makes sense, according to the reviews the gpu becomes much faster in performance mode, it has quite a lot of headroom that can be unleashed sacrificing battery life, and maybe scalding your hands, seems quite a lot of heat to dissipate for a phone
Thats why on desktop mobile games run fast.
"...the accompanying power consumption can go as high as 14W. Its average power usage seems to be around 9W."
Where did you get that information? No smartphone SoC can operate on a power budget like that. It would drain the battery in no time and burn your hand.
