Pentium 4 3.8ghz

The Intel Pentium 4 670 (3.8 GHz) stands as a historical landmark in computing, representing the maximum clock speed officially achieved by the single-core NetBurst architecture WikipediaHexus. Originally released in 2005 at a premium price of $851, it has transitioned from a high-end workstation component to a niche collector's item Encyclopedia.

Market Trends & Availability

* Collector Market Surge: While common Pentium 4 chips sell for scrap value ($1–$5), the 3.8 GHz model commands a premium among retro-computing enthusiasts building "ultimate" Windows XP gaming rigs Alibaba. Its value is driven by its status as the "Clock Speed King" rather than raw modern performance Hexus.

* Secondary Market Presence: Currently, these CPUs are primarily found in decommissioned enterprise inventory across India, Southeast Asia, and Eastern Europe Alibaba. On platforms like eBay, prices for functional units vary significantly based on condition and engineering sample status Ebay.

* Scrap vs. Value: Low-end P4 models are often processed for gold recovery (yielding 0.3–0.5g per unit), but the 670 model is actively preserved for its historical performance peak Alibaba.

Technical & Historical Insights

* End of the NetBurst Era: The 670 reached the thermal and scaling limits of its design, running so hot (115W TDP) that it earned a reputation as a "room warmer" HexusEncyclopedia. This led Intel to abandon the architecture in favor of the more efficient Core 2 Duo series Reddit.

* Bridge to 64-Bit: Despite its age, this chip was crucial in mainstreaming EMT64 (64-bit) computing, allowing legacy systems to break the 4GB RAM barrier Hexus.

* Modern Utility: In 2026, it is considered obsolete for modern web browsing or Windows 11, but remains vital for maintaining legacy industrial equipment like CNC controllers and medical devices Alibaba.
