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. This was the last Intel desktop socket to use a pin grid array interface. All later Intel desktop sockets use a land grid array interface. Socket 478 was phased out with the launch of LGA 775 in 2004.

LGA 775 was announced to have better heat dissipation properties than the Socket 478 it was designed to replace, but the Prescott core CPUs (in their early incarnations) ran much hotter than the previous Northwood-core Pentium 4 CPUs, and this initially neutralized the benefits of better heat transfer.
Socket 479 CPUs have exactly 478 pins just like socket 478 CPUs but the pins are in different locations so they won't plug into the wrong sockets--as they would not work. —Preceding unsigned comment added by 142.46.73.78 ( talk • contribs ) 19:10, August 29, 2006
Pentium 4 Willamette 1.5 GHz on Socket 423 Pentium 4 Prescott 2.4 GHz on Socket 478 Pentium 4 HT Prescott 3.0 GHz on Socket 478. At the launch of the Pentium 4, Intel stated that NetBurst-based processors were expected to scale to 10 GHz [15] after several fabrication process generations. However, the clock speed of processors using the ...
By adapting the multiplier the frequency of the CPU can throttle up or down to save power, given that all Socket P CPUs support EIST, except for Celeron that do not support EIST. Socket P has 478 pins, but is not electrically pin-compatible with Socket M or Socket 478. Socket P is also known as a 478-pin Micro FCPGA or μFCPGA-478.
In Intel's Tick-Tock cycle, the 2007/2008 "Tick" was the shrink of the Core microarchitecture to 45 nanometers as CPUID model 23. In Core 2 processors, it is used with the code names Penryn (Socket P), Wolfdale (LGA 775) and Yorkfield (MCM, LGA 775), some of which are also sold as Celeron, Pentium and Xeon processors.
For this reason, some manufacturers like Asus have made drop-in boards (e.g. CT-479) which allow the use of Socket 479 processors in Socket 478 boards. [3] Conversely, it is impossible to use any Socket 478 desktop Celeron and Pentium 4 processors in a Socket 479 board as they are electrically incompatible with Socket 479 despite being ...
