Intel Pentium 4 2.4 GHz - RK80532PC056512 (BX80532PC2400D)


Next Pentium 4 core - Northwood - was a die shrink of Willamette core. Based on 0.13 micron technology, Northwood microprocessors had lower voltage, and, as a result, lower power consumption than Willamette CPUs. The size of level 2 (L2) cache in this core was increased to 512 KB, besides that there were no major changes in microprocessor microarchitecture. Bigger L2 cache gave Northwood processors 5% - 20% speed boost over Willamette processors. Front-side bus frequency in first Northwood microprocessors didn't change. Over time the bus frequency was increased to 533 MHz, and finally to 800 MHz.
