This seems to be missing some of the technical merits of Intel's failure and rebirth: Downturn: The heat- and power-intensive single-core Pentium 4s, and the stillborn & binary-incompatible IA64/Itanium lineups that prevented them from competing on both the multicore and 64-bit AMD marketing bullet points Rebound: Dedicated, efficient "premium" laptop chips in the Centrino lineup, to which AMD had no competitors, and which subsequently reunified with the P4's Hyperthreading, plus multicore, in the "Core" lineup/microarchitecture that debuted in the newly-Intel, no-longer-PowerPC Macbooks. (I seem to remember hearing that Core-era Xeons were good, serverside: Nehalem definitely was, just afterwards)
