Socket 478 was used for all [[Pentium_4#Northwood|Northwood Pentium 4]] and [[Celeron]] processors. It supported the first [[Pentium_4#Prescott|Prescott Pentium 4]] processors and all [[Pentium_4#Willamette|Willamette]] Celerons, along with several of the Willamette-series Pentium 4s. Socket 478 also supported the newer Prescott-based Celeron D processors (which were also one of the last CPUs made for the socket), and early Pentium 4 Extreme Edition processors with 2 MB of L3 [[CPU cache]]. |

While Intel's mobile CPUs are available in 478-pin packages, they in fact only operate in a range of slightly differing sockets such as [[Socket 479]] (both mPGA478A and μFCPGA/μPGA479M), [[Socket M]], and [[Socket P]], all of which are electrically (and sometimes pin) incompatible with each other including Socket 478.{{Cite web|url=https://www.cpu-world.com/Sockets/Socket%20479%20(mPGA479M).html|title=Socket 479 / Socket mPGA479M|website=www.cpu-world.com|access-date=February 3, 2025}} |
