Not in 2010 when Paul Gentle recommended QorIQ over PA6T, yes, but they were in 2012/2013 when the Cyrus specs were conceived. I won't back away from my opinion that even without Paul's recommendation, A-Eon would have decided for the P5 in 2012/2013, simply because there was no feasible alternative for high-performance (in PPC terms, that is) desktop PPC.
