In January 2002, Intel akasunungura Pentium 4s ane itsva musimboti bumbiro zita "Northwood" panguva aimhanya 1.6 GHz, 1.8 GHz, 2 GHz uye 2.2 GHz. Northwood (chigadzirwa bumbiro 80532) akatanga kubatanidza kuwedzera L2 cache kukura kubva 256 KB kusvika 512 KB (kuwedzera transistor kuverenga kubva mamiriyoni 42 kusvika mamiriyoni 55) pamwe nokuchinja itsva 130 nm kugadzira muitiro. Kuita processor kubva duku transistors zvinoreva kuti anogona kumhanya panguva yakakwirira wachi nokukurumidza uye kubereka zvishoma kupisa.
