Intel Pentium Dual-Core E2140 2-core LGA 775
The 65nm Allendale core delivers basic dual-threaded processing at 1.6GHz with a modest 65W TDP, making it a low-power option for legacy LGA 775 systems. Its 800 MHz FSB and 1MB L2 cache provide adequate throughput for period-correct Windows XP or lightweight Linux tasks, backed by a reliable boxed cooler. This processor is best for retro PC builders restoring vintage desktops or maintaining aging office machines that require a drop-in dual-core upgrade.
