Not from what I've understood; it seems as if they have multiple functional units on their chip. Nice idea, of course: Seymour Cray had it in the CDC Cybers, decades ago (ob. Seymour plug 8-)), and so do MIPS chips, I believe (although I'm not sure how many the MIPS chips have). And, of course, the 8088 and 8087 could operate in parallel.
