Only if Intel is also _perceived_ as the inferior product. Remember that the value to the customer goes beyond raw benchmarking specs; it also includes brand reputation and marketing.
At the level of truly huge purposes, "value" also encompasses a real bilateral relationship between the company and vendor. A cloud provider might be tempted to stay with Intel now over AMD if by doing so they preserve guaranteed access/preferential pricing over the next set of server chips. To crack that hypothetical relationship, AMD would have to both dominate now and be perceived to dominate for the medium-term future.
It's only the retail market that can be so fickle as to consider a CPU a one-off purchase.
