AMD just needs to get busy and get a license from ARM holdings and try to catch up with Nvidia and TI.
Intel can always emulate Coke and Pepsi who spun off their bottling operations.
Intel does and doesn’t have a huge anchor with their fabs.
Intel and IBM are the two bleeding edge fabs in the world. Intel can’t outsource the fab issue to IBM - IBM doesn’t have the throughput to deliver the amount of product that Intel needs, and no one else is going to put the cash into creating a bleeding edge fab to serve Intel.
So yea, it is an anchor. It is also a barrier to entry for everyone else.
