Kantor is very very smart. You would almost think that hes the smartest and most capable person here, at least until Alephnul gets off his butt and starts posting again.
In many respects, the evolution of mainstream x86 microprocessors over the last 10-15 years has been very consistent, steady and gradual, with a few exceptions. Since the advent of their first out-of-order designs, both AMD and Intel have been using very similar microarchitectures throughout successive generations. The notable exception is Intel’s Pentium 4, which proved to be poorly suited for most of the market. That aside, the heritage of AMD’s designs is very clearly descended from the K7 generation, while Intel’s microarchitectures are derived from the Pentium Pro. AMD and Intel both focused on the same initial design goals: maximal single threaded performance given reasonable manufacturing costs. Around 2003, the additional constraint of power efficiency became essential - both to accommodate affordable cooling solutions, electrical delivery and also the rise of notebooks. While this change (amongst other things) doomed the Pentium 4, the challenges of power efficiency were mostly met by continuous improvements rather than radical departures. The x86 ecosystem is largely ruled by two microarchitectures, Intel’s Nehalem and AMD’s Istanbul (for simplicitly we use Istanbul to refer to all of Family 10h). Together these two designs span the entire PC market from 10W notebooks to 130W servers, with a third for the somewhat different ultra-low power market (Intel’s Atom).
