Description

Intel Pentium 4 SL5UJ 1.6GHz Socket 478 CPU 256KB Cache 400MHz FSB Willamette

A single-core desktop processor from Intel's Pentium 4 lineup, built on the Willamette core architecture. This CPU was used in consumer and business desktop systems from the early 2000s.

Specifications & What's Included

  • Clock Speed: 1.6 GHz
  • Socket Type: Socket 478 (mPGA478B)
  • L2 Cache: 256 KB
  • FSB: 400 MHz
  • Core Voltage: 1.75V
  • Manufacturing Process: 0.18 micron
  • Single core processor
  • CPU only — no heatsink, fan, or retention bracket included

Applications

Socket 478 Pentium 4 processors were compatible with Intel 845, 865, and i915 chipset motherboards. These CPUs were standard in desktop systems throughout the early-to-mid 2000s for general computing, office applications, and consumer-level tasks. This processor is now used primarily in retro computing builds, legacy system restoration, or compatibility testing for older platforms.

Condition: Used
This Intel Pentium 4 SL5UJ 1.6GHz Socket 478 processor has been inspected and is in good condition.
