Duba wurin da ke ƙasa sannan ka amsa tambayar daga baya a cikin harshe ɗaya kamar yadda wurin yake:  Passage: A ranar 1 ga Fabrairu, 2004, Intel ta gabatar da sabon mahimmin lamba mai suna "Prescott". Jigon ya yi amfani da tsarin 90 nm a karon farko, wanda wani manazarci ya bayyana a matsayin "babban sake fasalin microarchitecture na Pentium 4". Duk da wannan gyare-gyare, nasarorin da aka samu ba su da daidaito. Wasu shirye-shirye sun amfana daga ɓoyayyen ɓoye na Prescott da umarnin SSE3, yayin da wasu suka cutar da bututun mai da ya fi tsayi. Tsarin microarchitecture na Prescott ya ba da damar saurin agogo kaɗan, amma ba kusa da yadda Intel ya zata ba. Mafi saurin samar da Pentium 4s na Prescott da aka yi amfani da shi ya kasance a 3.8 GHz. Duk da yake Northwood a ƙarshe ya sami saurin agogo 70% mafi girma fiye da Willamette, Prescott ya haɓaka 12% fiye da Northwood. Prescott ta rashin iyawa a cimma mafi girma agogon gudu da aka dangana ga sosai high ikon amfani da zafi fitarwa na processor. Wannan ya haifar da mai sarrafawa ya karɓi laƙabi "PresHot" a cikin majalisai. A zahiri, ikon Prescott da halayen zafi sun kasance kaɗan ne kawai fiye da na Northwood na saurin daidai kuma kusan daidai yake da Extreme Editions na tushen Gallatin, amma tunda waɗancan masu sarrafawa sun riga sun yi aiki kusa da iyakokin abin da aka ɗauka a matsayin abin karɓa na zafin jiki, wannan har yanzu yana haifar da babbar matsala. "Prescott" Pentium 4 ya ƙunshi transistors miliyan 125 kuma yana da yanki na 112 mm2. An ƙera shi a cikin aikin 90 nm tare da matakan jan ƙarfe guda bakwai. Tsarin yana da fasali kamar su silicon transistors da Low-K carbon-doped silicon oxide (CDO) dielectric, wanda kuma aka sani da gilashin organosilicate (OSG). An fara kera Prescott a masana'antar ci gaban D1C kuma daga baya aka koma shi zuwa masana'antar samar da F11X. Asali, Intel ta saki layukan Prescott guda biyu: jerin E, tare da 800 MT / s FSB da Hyper-Threading tallafi, da ƙananan ƙarshen A-jerin, tare da 533 MT / s FSB da Hyper-Threading naƙasasshe. Intel ƙarshe ya ƙara XD Bit (eXecute Disable) da Intel 64 aiki zuwa Prescott.  Tambaya: Nawa nm ne ainihin ya yi amfani?
