Intel Core 2 Duo E7400 2-core LGA775
The provided specs are contradictory, listing modern features like DDR5 memory and a 4.3GHz boost clock that this legacy 45nm Core 2 Duo chip cannot support, making the listed PassMark score of 20507 impossible for its actual 2.8GHz base frequency. Its real-world strength lies in its unlocked multiplier on the LGA 775 socket, offering a low-cost entry point for overclocking experimentation on vintage systems. This processor is best for hobbyists maintaining legacy Windows XP or retro gaming rigs who need a direct, period-correct replacement part.
