What is the deal with mobile GPUs vs PC GPUs? (lemmy.world)

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?

mobile GPUs being ARM based

Could you elaborate?

ARM is an instruction set similar to x86 however it is more power efficient, for a number of reasons.

It doesn’t help the confusion that ARM is a company and produces CPUs and GPUs but you can find the ARM instruction set in use on a wide range of SoC and other hardware.

It is popular for use cases where power efficiency is important.

For example Apple uses the ARM instruction set for their M serious which are a SoC containing CPU, GPU and memory.

SoC = System on a Chip.

I think you might be confusing the ARM instruction set with the ARM company. I don't have any insider knowledge, but I don't think the Mali GPU is based on the ARM instruction set.
