It’s a little amusing how many respondents thought mobile GPUs meant laptop GPUs despite it being clear in your post.
There are several factors at play from mobile GPUs being ARM based, having unified memory and some laws of physics meaning more size and power has diminishing returns.
Phone GPUs based are generally comparable to budget desktop GPUs on a per generation comparison.
Despite this mobile games tend to look amazing compared to what you would expect out of a PC game on low end hardware.
Part of this is optimisation, part of it is more efficient graphics libraries targeting a much lower range of hardware. Similar to how lower spec consoles often have great looking games, targeting only one hardware layout can allow for crazy optimisations.
See the PS3 era games for examples of really pushing hardware to its absolute limits for graphics.
Sadly my answer isn’t as technically detailed as Id like but it’s a complex topic when you really delve into it.
I appreciate the well thought out response!
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.
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.
