When first released in 2001, Itanium's performance was disappointing compared to better-established [[RISC]] and [[Complex instruction set computing|CISC]] processors.<ref name="anand"/><ref name="Venturebeat"/> Emulation to run existing x86 applications and operating systems was particularly poor, with one benchmark in 2001 reporting that it was equivalent at best to a 100&nbsp;[[Hertz|MHz]] Pentium in this mode (1.1&nbsp;[[Hertz|GHz]] Pentiums were on the market at that time).<ref>{{cite news

Itanium failed to make significant inroads against [[IA-32]] or RISC, and suffered further following the arrival of [[x86-64]] systems which offered greater compatibility with older x86 applications.

In a 2009 article on the history of the processor — "How the Itanium Killed the Computer Industry" — journalist [[John C. Dvorak]] reported "This continues to be one of the great fiascos of the last 50 years".<ref>{{cite web
