Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Musi waFebruary 1, 2004, Intel yakaunza chinyorwa chitsva chinonzi "Prescott". Kori yacho yakashandisa muitiro we90 nm kwenguva yokutanga, uyo mumwe muongorori akarondedzera se"kugadziridza kukuru kwepentium 4's microarchitecture". Pasinei nokuvandudzwa uku, kushanda zvakanaka kwacho kwakanga kusingaenderani. Mamwe mapurogiramu akabatsirwa nePrescott's doubled cache uye SSE3 mirayiridzo, nepo vamwe vakakuvadzwa nepayipi yayo yakareba. Prescott's microarchitecture yakabvumira kukurumidza kwewachi yakakwirira, asi kwete yakakwirira seIntel yakanga yakatarisira. MaPentium 4s akakurumidza kugadzirwa muPrescott aive ne3.8 GHz. Apo Northwood pakupedzisira yakawana wachi inomhanya 70% yakakwirira kupfuura Willamette, Prescott akakwira 12% kupfuura Northwood. Kusakwanisa kwaPrescott kuwana kumhanya kwakanyanya kwewachi kwakanzi kwakakonzerwa nekushandisa kwesimba kwakanyanya uye kupisa kupisa kwe processor. Izvi zvakatungamirira processor kugamuchira zita remadunhurirwa rokuti "PresHot" pamusoro forum. Kutaura zvazviri, Prescott simba uye kupisa unhu vakanga chete zvishoma kupfuura avo Northwood zvakafanana nokukurumidza uye anenge akaenzana Gallatin-inobva Extreme Editions, asi sezvo processors avo vakanga vatova kushanda pedyo miganhu chii chainzi thermally zvinogamuchirika, ichi achiri akamisa nyaya huru. The "Prescott" Pentium 4 rine mamiriyoni 125 transistors uye ane die nzvimbo 112 mm2. Yakagadzirwa nenzira ye90 nm ine nhanho nomwe dzokubatana kwemhangura. Maitiro acho ane zvinhu zvakadai seyakagadziriswa silicon transistors uye Low-K kabhoni-doped silicon oxide (CDO) dielectric, iyo inozivikanwawo se organosilicate girazi (OSG). The Prescott yakatanga kugadzirwa panguva D1C kukura fab uye akazoendeswa kuna F11X kugadzirwa fab. Pakutanga, Intel akasunungura mbiri Prescott mitsetse: E-dzakatevedzana, ane 800 MT / s FSB uye Hyper-Threading rutsigiro, uye yakaderera-kuguma A-dzakatevedzana, ane 533 MT / s FSB uye Hyper-Threading akaremara. Intel pakupedzisira akawedzera XD Bit (eXecute Disable) uye Intel 64 functionality kuna Prescott.  Mubvunzo: Intel yakaunza rini zita idzva romutemo rinokosha rokuti 'Prescott'?
