Hi everyone, would it be possible to overclock the SD855 inside the Pixel 4 XL to reach SD855+ levels of performance? If anyone has done it how well did this go for you?
Overclock to get SD855+ Performance?

You won't get very far by overclocking a phone CPU. There simply isn't enough cooling capacity; you'd damage the processor before you got any appreciable increase in performance.
No problem. If this was an experimental bench top type thing where you had the board in a specially made jig with an actively cooled heat sink applied to the CPU...then sure, you could try. There's two problems with overclocking: frequency and power, both of which generate heat. Overclocking means you're running everything at a higher frequency than it was designed for. While this can theoretically perform operations faster, it also generates more heat, and to keep everything stable, you have to increase the voltage as well. So, you could potentially overclock a mobile CPU to the point where you actually saw some appreciable performance gain, but because a phone/tablet does not have sufficient ability to reject heat, the system would quickly overheat.
That's why overclockers generally have heavy duty liquid cooling systems, even to the point of using liquid nitrogen for extreme overclocking.
