Intel Pentium 4 641 1-core LGA 775
The 65nm Cedar Mill core and 2MB L2 cache deliver notably better thermal efficiency than earlier Pentium 4 chips, with a 3.2GHz clock speed and 800 MHz FSB for basic single-threaded tasks. Its 115W TDP and LGA 775 socket make it a drop-in upgrade for legacy systems needing Hyper-Threading support without a full platform rebuild. This processor is best for retro PC builders restoring Windows XP-era gaming rigs or maintaining industrial equipment tied to specific legacy hardware.
