What is scoket 478?

Socket 478, also known as mPGA478, was a CPU socket used by Intel for their Pentium 4 and Celeron processors in the early 2000s. It was launched in 2000 and remained in use until 2004.

Socket 478 supported a front-side bus speed of up to 800 MHz and processors based on the Northwood and Prescott core architectures. These processors typically ranged in speed from 1.3 GHz to 3.4 GHz.

The socket used a 478-pin grid array, hence the name, and required a separate CPU cooler for cooling. The package size for processors using Socket 478 was 31mm x 31mm.

Socket 478 processors were used in desktop computers and early laptops. However, it was eventually replaced by Socket 775 (LGA775) as Intel moved towards more energy-efficient and powerful processors.

Overall, Socket 478 was a popular choice for Intel processors in the early 2000s and helped lay the groundwork for future CPU socket designs.
