p4 socket 423 vs 478

[Blackened]

Can someone explain the differences between these aside from the layout?
Which one is preferable, and why? thanks

Currently, there's no difference in the die... Just the packaging. S478 is the future, and the future P4's will be S478 (including the upcoming Northwood .13um). So, if you are planning on buying a P4, S478 would be the way to go for better future compatibility

What Wingz said 🙂

Yep, current S478 CPU's are the same .18um Williamette core but this socket will support like Wingz said, future .13um Northwood's. Northwood will have internal improvements over Williamette, possibly use a Quad Pumped 133fsb, and will have 512k L2 Cache over 256k's on Williamette. It's gonna be good.

Ack, do all socket 478 boards support only sdram? That sucks 🙁

 

[Athlon4all]

Nope. Abit TH7II-RAID (850) is S478, Shuttle AV40R (P4X266), Acorp's and Azza's P4X266 solutions are S478 also. Asus is making the P4T-E (850) to use S478 also.

Intel 478 850 chipset boards are also available.
