If it was easy to make better processors everyone would be doing that. The exynos 2400 improved much more compared to previous generations. Better heat spread will mean improved performance and thermals. As for efficiency newer nodes should improve on this front.
Rather than make better processors they just make them dispate heat better.
These are also googles ‘own design processors’, so bad Samsung even avoids useing exynos. Next gen pixels will definitely be the hottest phone around.
You can improve heat dissipation, but it’s going to cost battery life to produce that heat. This is not a great solution. It’s a mitigation.
