Why do modern low power CPUs offer comparable performance to high-end consumer CPUs of the past while low-power GPUs do not? For example recent mobile SoCs (Snapdragon 888/Apple A14) CPUs offer very comparable performance to consumer CPUs of say the past 5 years. But for GPUs, it's a different story, where current mobile GPUs are still vastly weaker than consumer GPUs from even 2014?

I'm really curious as to why that is the case
