I le aso 1 Fepuari 2004, Intel faalauiloa se autu fou code-igoa "Prescott". O le autu faaaogaina le 90 nm faagasologa mo le taimi muamua, lea o se tasi auiliili faamatalaina o "a reworking tele o le microarchitecture Pentium 4". E ui lava i lenei toe faafouina, o le faatinoga o tupe mama sa le ogatasi. faamanuiaina nisi polokalame mai cache faaluaina o Prescott ma SSE3 faatonuga, ao isi na afaina i lona pipeline umi. faatagaina microarchitecture a Prescott saoasaoa uati teisi maualuga, ae e le toeitiiti lava e pei ona maualuga e pei Intel na faamoemoeina. na vave gaosia vaega tele Prescott-faavae Pentium 4s na uati i 3.8 GHz. ao Northwood uati ausia 70% maualuga atu nai lo Willamette, Prescott faalauteleina i tala atu o Northwood. ua uma ona tuuina atu i le tele o galuega faatino a Prescott e ausia e sili atu nai lo le uati o le Pentium 4s.
