Yes, I'm sure. The only date I specifically mentioned was 2003, which is when the last Alpha was released and the 64 bit x86 architecture became available. In 1998-1999 the Alpha was still probably in the lead on all counts except possibly price/performance. Things move fast in CPUs, and a significant lead one year can turn into a trailing position the very next.

Well... By 2003 the Alpha has been more or less abandoned in terms of R&D expenditures. It's impossible to estimate how much of its perceived lack of relative performance was due to progresses in x86 designs and how much was simply due to a lack of research in progressing the architecture.
