is there an underlying difference to these?

was one for the willamette the other for northwood or where there other reasons?

socket 423 - pentium 3
socket 478 - pentium 4 (willamette and northwood)

That is wrong.
Socket 423 was the early P4 socket, it only goes up to 2gigs and is only for willamettes.
Socket 478 is for newer P4 chips some older willamettes are supported all northwoods are supported. Northwoods start at 1.6Ghz and up.
Socket 370 for the Cu P3s and i think some Katmai.
My opinion is stay away from the 423.

thanks for clearing that up

AFAIK Socket 423 is also physically larger, and Socket 478 is smaller. I could be wrong.

While at it:

Socket 3: 486s I think
Socket 5: Pentium/Pentuim Pro <- not sure
Socket 7/SS7: Pentium, AMD K6-2, Winchip, some Cyrixes
Socket 462 aka Socket A: AMD CPUs: Durons/MPs/Xps/Tbirds
Socket 370: Pentium 3/Celeron/SOme cyrixes (newer ones)
Socket 423: early pentium 4s <- AVOID THESE!
Socket 478: newer pentum4s

Slot A: Older Athlons
Slot 1: Pentium II/III
Slot 2: PII/PIII Xeons

Yeh the 423 is physically larger, the 478 has the pins packed closer together. While on the topic wasn't the Socket7 and socket 5 almost identical?

AFAIK, yes.

Socket 5 was for earlier Pentium CPUs, socket 7 was used for later ones. (90MHz upwards I think).

Socket 5's are all single voltage if I remember right. To run a dual voltage (MMX) CPU you'd need socket 7 but the socket 7 boards were backwards compatible to socket 5 CPU's too.

Pentium Pro's are socket 8. Big honkers.
