Same socket

New 478-pin micro-PGA package for desktop Pentium 4 microprocessors was introduced in August 2001 together with 1.9 GHz and 2 GHz versions of Pentium 4s. Almost full line of Willamette CPUs, starting from this Pentium 4 1.4 GHz, was also converted to use the brand-new 478-pin package. This package, compatible with socket 478 motherboards, had 35% smaller width and height, and 57% smaller package area than original Pentium 4 CPUs. This reduction in size was achieved by cutting distance between pins in half. The smaller package was the major change in socket 478 Willamette processors. There were also minor differences between socket 423 and 478 versions of Pentium 4 in electrical characteristics, maximum operating temperature and Thermal Design Power. All major CPU features, such as micro-architecture, size of cache memory, support for SIMD instructions, etc, stayed the same on socket 478 Willamette processors.

Socket 478 Willamettes do not have any performance advantage over socket 423 CPUs, but they provide much better upgrade path. In most cases, this 1.4 GHz CPU can be upgraded to 2.6 GHz Pentium 4 with 400 MHz FSB, or, even to faster, but significantly more rare, 2.8 GHz and 3 GHz Pentium 4s with 400 MHz FSB. Socket 423 CPUs can be upgraded to Pentium 4 2 GHz. Although socket 423 motherboards can be used with faster socket 478 processors, you will need to buy a special socket 423-to-478 adapter for that, and the cost of the adapter is usually higher than the cost of the Pentium 4 2.6 GHz, even years after Pentium 4 family became obsolete. Other upgrade options for this socket 478 Pentium 4 CPU depend primarily on the motherboard. If the motherboard supports 533 MHz FSB then you should be able to upgrade to Pentium 4 3.06 GHz with Northwood core. If, by any chance, the motherboard supports 800 MHz FSB, then you may be able to upgrade to Pentium 4 3.4 GHz, or, if the Prescott core is supported by your board, to Pentium 3.8 GHz.
