Not sure about that bit...
What is well known however, is that a bunch of Alpha engineers wound up at AMD, and a lot of that DNA went into the OG Athlon
QPI was Intel's answer to the competition AMD's Athlon / HyperTransport had created
The funny part is that arguably both HyperTransport and QPI descend from the interprocessor links designed for Alpha EV7
