In January 2002, Intel sii daayay Pentium 4s la code core cusub loo magacaabay "Northwood" xawaare ah 1.6 GHz, 1.8 GHz, 2 GHz iyo 2.2 GHz. Northwood (code wax soo saarka 80532) bilaabay in ay isku daraan kororka L2 size cache ka 256 KB in 512 KB (kor u qaadida tirada transistor ka 42 million in 55 million) la kala guurka ah in habka cusub ee soo saaridda 130 nm. samaynta processor ka transistors yar ka dhigan tahay in ay ku ordi karaan xawaare saacad sare iyo soo saaraan kulayl yar. isla bishii guddiyada isticmaalaya chipset 845 ayaa la sii daayay la taageero karti u leh DDR SAM kaas oo bixiyay laba jeer bandwidth ee PC133 SDRAM, iyo yareeyo kharashka sare ee isticmaalaya RAM Rambus for xawaare ugu badan ee 4.86 GHz. Pentium 4 Pentium 4A ayaa la sii daayay bishii Abriil 2, 2002, Northwood (code wax soo saarka 80532) isku daray korodhka ah ee L2 size cache ka 256 KB in 512 KB (kor
waxay ku socdaan xawaare saacad ka sareeya waxayna soo saaraan kuleyl yar
