What is the difference betwen Intel Socket 479 & 478?

[BillyBatson]

I was about to purchase one of those Aopen MiniPc things for my sister but they all seem to use socket 479? Newegg only has 1 479 listed and it is a celeron BAH. I want to purchase this and a pentium M 479 but i want ot know the difference, is Socket 479 for the older pentium (pre core solo/duo?) ??

478 was earlier Pentium 4. Willamette and Northwood, even some Prescotts I think.

478 is for desktops and Pentium 4M. 479 (of which there are two mutually incompatible variants, watch out) is for laptops using Pentium M or Core.

IIRC, Newegg lists most Socket 479 chips under Socket 478.

From some reading, it appears that you need a Pentium M (or Celeron M).

Socket 478 is for the Northwood and early Prescott Pentium 4 chips, while Socket 479 is the Pentium M chips as well as the Core Duo chips I believe. Yes, I believe Aluvus is right, Newegg does list the mobile chips under socket 478, but they are 479. Asus makes an adaptor for socket 479 that works on some ASUS motherboards, letting you run a mobile chip in a desktop board.

Here is a link. I believe AOpen and others also make specific S479 boards.

You'd be surprised at the processing power of a Celeron-M.

Well, a Celeron M is just a 400MHz FSB Pentium M with half the cache and no speedstep...what is there to be surprised about? Its performance will be similar...

BGA Pentium/Celeron M are socket 479. PGA are 478
