Doubt.
Neither of the companies is particularly competitive on either processor or GPU architecture nor fabrication.
A merger of those entities looks like nothing but a recipe for further x86 stagnation and an even quicker death for the entities involved imho.
In particular I cannot see what's good in it for AMD. The fabs have no use/clear path forward. Their processors/gpu either match our outmatch the Intel offering.
A Broadcom/Apple takeover of Intel sounds much more reasonable.
