Socket 478 (also known as mPGA478, mPGA478B) is a 478-contact CPU socket used for Intel's Pentium 4 and Celeron series CPUs. Socket 478 was launched with the Northwood core to compete with AMD's 462-pin Socket A and their Athlon XP processors. Socket 478 was intended to be the replacement for Socket 423, a Willamette-based processor socket which was on the market for only a short time. Socket 478 was phased out with the launch of LGA 775. ==Technical specifications== Socket 478 was used for all Northwood Pentium 4 and Celeron processors. It supported the first Prescott Pentium 4 processors and all Willamette Celerons, along with several of the Willamette-series Pentium 4s. Socket 478 also supported the newer Prescott-based Celeron D processors, and early Pentium 4 Extreme Edition processors with 2 MiB of L3 CPU cache. Celeron D processors were also available for Socket 478 and were the last CPUs made for the socket. While the Intel mobile CPUs are available in 478-pin packages, they in fact only operate in a range of slightly differing sockets, Socket 479, Socket M, and Socket P, each incompatible with the other two. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Socket 478」の詳細全文を読む スポンサード リンク
