For anyone who knows.
Basically, it seems to me like the technology in mobile GPUs is crazier than desktop/laptop GPUs. Desktop GPUs obviously can do things better graphically, but not by enough that it seems to need to be 100x bigger than a mobile GPU. And top end mobile GPUs actually perform quite admirably when it comes to graphics and power.
So, considering that, why are desktop GPUs so huge and power hungry in comparison to mobile GPUs?
To the best of my knowledge ARM company is not involved in making GPUs, and ARM CPUs don’t influence performance of GPUs. Board and system architecture might though, such as unified memory, which could be part of the memory controller and physically Co exist with the CPU?
ARM makes GPUs, which are primarily used in phones, and this isn’t hard to lookup.
The ARM instruction set which is an alternative to x86 is also another matter.
