Socket type question

[theBLACKout]

on intel website: http://ark.intel.com/product.aspx?id=32427&code=t5550
for t5550, the product name is call "Intel® Core™2 Duo Processor T5550 (2M Cache, 1.83 GHz, 667 MHz FSB) TJ, uFCPGA Pb-Free SLI, Socket P, Tray", but its socket is PPGA478. i am really confused. On http://www.eworldsale.com/intel-core-2-duo-mobile-processor-t5550-183ghz-2mb-cpu-oem_5783_21966.html, it said t5550 socket type is Micro-FCPGA. So what is t5550 socket's type, socket 478 or socket p or Micro-FCPGA?

It's a mobile CPU. It's a C2D, but it's different from a desktop C2D. For all intents and purposes, it's a 478.

so it is socket 478, but then how come it has socket p in its name

Its not socket 478, its a 478pin socket known as socket P.

Desktop computers use lga 775(a 775 pin land grid array) for pentium 4 prescotts up to the latest core 2 duos, and then lga 1366 for the new i7 processors.
