About Intel Core Duo ULV L2500

The Intel Core Duo ULV L2500 was a specialized mobile processor designed for ultra-low power consumption. In practical performance, this dual-core chip delivered adequate responsiveness for its era, handling basic tasks like web browsing and office applications smoothly. However, its relatively low 1.2 GHz clock speed meant it struggled with demanding software and multitasking. The Core Duo ULV L2500's primary strength was its extremely low 9W TDP, enabling its use in exceptionally thin and light laptops. Common characteristics of systems using this CPU included:

  • Adequate for basic productivity software
  • Noticeable lag with multiple applications open
  • Excellent battery life for mid-2000s standards
  • Integrated graphics unsuitable for gaming
Overall, the Core Duo L2500 was a trade-off, prioritizing energy efficiency over raw computing power.

When considering the value proposition of the Intel Core Duo ULV L2500, it was a niche product for users prioritizing portability above all else. Productivity benchmarks of the time would have shown it lagging behind its full-voltage counterparts, but it provided a competent mobile computing experience. Motherboard support was limited to the proprietary Intel Socket 479, found in a select range of compact notebooks from manufacturers like Sony and Lenovo. Key considerations for this platform include:

  • Extremely limited upgrade path due to specialized socket
  • Platform longevity hampered by the 65nm process technology
  • Ideal for business users needing long battery life
  • Quickly surpassed by the subsequent Core 2 Duo architecture
The Intel Core Duo ULV L2500 processor carved out a specific role in the market, serving a need for ultra-portable computing before ultrabooks became mainstream.
