Thanks for moving the topic.
It’s not only about the core design, the SoC’s reached a limit where power management, and smart cpu throttle algorithms to handle the temperature are a must!
I think only Apple is honest about their SoC’s speed, they are able to keep the Ghz up to 20Minutes straight.
When it comes to power management and thermal management, Qualcomm is far far behind, MTK at least. (I don’t know about Samsung)
I found it only in German, so I wont share it here, the short summary is. This is how MTK does it.
The MTK Helio X10 gives the user straight only 6 out of 8 cores to start with, because it doesn’t know the room temperature and to swap cores if they get too hot. This goes on for some minutes, if the temperature is save the MTK Helio X10 will give the user all 8 cores, the thing will actually get better in Antutu the more often you start it, but never worse.
While the Qualcomm way is… full full speed, first A57 core down, full speed 2nd A57. full speed 3rd A57 down and so on until all 4 A57 are dead and only the four A53@1.7Ghz are running, this happends long before 20 minutes are over.
It’s pretty obvious that how Qualcomm does/ did it is very stupid. That’s what I meant with they have a lot to learn.
In daily use it is hard to push either of these 2 SoC’s to it’s limits, so the SD810 wont go down too badly, but the heat and rapid battery train is noticeable.
Funny remark: I have read that in the X20 and X30 MTK will add two or four cores that just work in the benchmark mode, and are useless or mostly useless in daily use. At least MTK is willing to learn from Qualcomm :D
