In overall energy efficiency and thermal throttling, Exynos 2200 is still better compared to SD888. (I got the SD888 in OnePlus 9 Pro), and I also have the SD8 Gen 1 in the S8 Ultra TAB.In overall energy efficency, thermalthrottling exynos is weak especially compare to SD 865.
Next optimalization this SOC is low so is visivility often.
In daily use for a lot users clean performance isn't most important.
I have compare fold 2 and s22u with exynos.
Thurst me battery and smooth isn't even similar to fold 2 with "old" sd865
Keep in mind that the SD865 is still one of the most efficient SOCs among Qualcomm.
Not saying Exynos 2200 is the "best" but rather that it's still sitting between SD888 and SD8 Gen 1, and that's coming now from my own comparissons and tests done with Scene 5, measuring the power consumption, temperature under XY loads and overall heat dissipation among them (though TAB doesn't really count since the battery is not affected by high SOC temps on TABs like the phones are).
OnePlus 9 Pro - S22 Ultra - S8 Ultra TAB. (I got the S7 Plus TAB too with the SD865 Plus). (And many other devices).
