They are seriously hurting Intel in the datacenter space, but Intel is not dead yet and their accelerator have so far seen very small adoption. They are fabless meaning that their margins are capped, x86 mobile CPUs are under attack from ARM and all hyperscalers are working on their own accelerator with some degree of success. They won't move to AMD GPUs.
They are a good company putting out great hardware, but at the current price I just don't get it.
