Rịba ama amaokwu a dị n'okpuru ma zaa ajụjụ ahụ mgbe e mesịrị n'otu asụsụ ahụ dị ka amaokwu ahụ:  Passage: Na Febụwarị 1, 2004, Intel webatara ihe ọhụrụ a na-akpọ "Prescott". Ọ bụ nke mbụ a na-eji usoro 90 nm eme ihe, nke otu onye nyocha kọwara dị ka "nnukwu mgbanwe nke microarchitecture Pentium 4". N'agbanyeghị mgbanwe a, uru ndị a na-erite n'ọrụ adịghị agbanwe agbanwe. Programsfọdụ mmemme ritere uru site na Prescott okpukpu abụọ na ntuziaka SSE3, ebe ndị ọzọ merụrụ ahụ site na pipeline ya toro ogologo. Prescott's microarchitecture kwere ka obere elekere elekere, ma ọ bụghị ihe dị elu dị ka Intel tụrụ anya ya. Pentium 4s kachasị ngwa ngwa nke Prescott mepụtara na 3.8 GHz. Mgbe Northwood mechara nweta elekere elekere 70% dị elu karịa Willamette, Prescott gbatịrị 12% karịa Northwood. Enweghi ike nke Prescott iji nweta ọsọ ọsọ elekere ka ukwuu bụ n'ihi oke ike ọkụ na ọkụ ọkụ nke onye nhazi ahụ. Nke a mere ka onye nhazi ahụ nweta aha otutu "PresHot" na forums. N'eziokwu, ike na okpomọkụ nke Prescott dị ntakịrị karịa nke Northwood nke otu ọsọ ahụ na ihe fọrọ nke nta ka ọ bụrụ nke dị ka Gallatin dabeere na Extreme Editions, ma ebe ọ bụ na ndị nhazi ahụ na-arụ ọrụ n'akụkụ ókè nke ihe a na-ewere dị ka ihe a na-anabata, nke a ka na-eweta nnukwu nsogbu. "Prescott" Pentium 4 nwere 125 nde transistors ma nwee ebe obibi nke 112 mm2. Ejiri usoro 90 nm mepụta ya na ọkwa asaa nke njikọ ọla kọpa. Usoro a nwere njirimara dịka silicon transistors na Low-K carbon-doped silicon oxide (CDO) dielectric, nke a makwaara dị ka iko organosilicate (OSG). E mepụtara Prescott mbụ na D1C mmepe fab ma emesịa kwaga na F11X mmepụta fab. Na mbido, Intel wepụtara ahịrị Prescott abụọ: usoro E, yana 800 MT / s FSB na nkwado Hyper-Threading, yana usoro A dị ala, yana 533 MT / s FSB na Hyper-Threading nwere nkwarụ. Intel mechara gbakwunye XD Bit (eXecute Disable) na Intel 64 arụ ọrụ na Prescott.  Ajụjụ: olee mgbe Intel webatara aha ọhụrụ 'Prescott'?
