Applications
The Pentium 4 Socket 478 platform was Intel's mainstream desktop processor socket from 2001 through roughly 2004, supporting a wide range of Willamette and Northwood-core Pentium 4 chips as well as early Celeron 4 derivatives. Socket 478 boards were paired with chipsets such as the Intel 845, 848, 850, 865, and 875 series. This processor is relevant to builders and collectors restoring period-correct early-2000s desktop PCs, system integrators maintaining legacy industrial or embedded Socket 478 hardware, and hobbyists sourcing spare processors for workstation or thin-client boards that require this socket. The Willamette core (SL5YR) was the first-generation Pentium 4 architecture, later succeeded by the Northwood core at higher clock speeds on the same Socket 478 platform.
This Intel SL5YR Pentium 4 2.0GHz Socket 478 CPU is being sold as-is, for parts or repair. It is not guaranteed to be functional and has not been tested at our facility. The processor shows light handling wear consistent with prior use; the IHS (integrated heat spreader) and pin array appear intact and undamaged in photos.
