AMD was almost bankrupt 10 years ago. Basically AMD had to bet the whole company on their next CPU or GPU and their choice was the CPUs and put all their efforts into that and it payed off (Zen architecture).

It has only been the last 4 or 5 years that AMD has had any real money to put into their GPU/AI accelerator sector and that seems to be developing quite well now (though they seem to be mostly interested in super computer/massive data center deployments for now)
