The only thing AMD CPUs and GPUs can effectively modulate is the size of your sphincter opening, fanboi.
Dell already has ARM-based servers...using Marvell ARM CPUs. Samsung has been working on its ARM server CPU design for many quarters with early preview technology for ARM64, which AMD is only just receiving.
AMD is a second rate "me too" x86 vendor, a second rate "I wish" GPU vendor and is now trying to become a second rate ARM Server CPU vendor, up against much better competitors. Bankruptcy in 2 quarters.
