Socket 478 vs 423

[mis3]

I am shopping for a new P4 CPU and I'm a bit confused. Is there any performance difference between the socket-478 and 423 P4? Based of the current pricing, I'm thinking of a 1.8 GHz and is there a Northwood 1.8 GHz?

The Northwood 1.8 is just starting to trickle out (along with the 1.6), so if you see one from a reputable dealer, grab it.

Make sure you get socket 478. Socket 423 is the older version that is now outdated.

I understand that the Northwood CPU has larger 512 KB L2 cache and 0.13 micron technology. How about the Williamette core CPU, is there a performance difference between the 423 and 478 socketed CPUs?

I don't believe there is any performance difference, but the 423 is dead.

There is no difference between the Willamette 423 and the Willamette 478, except for the packaging (socket they fit in, basically).

Socket 423 can take willimete CPU
Socket 478 can take willimete and Northwood also smaller.Also it seem that socket 478 goes faster by 1% reason unfound is like why a celeron tuatulin 133 FSB is slower that a P3 tuatulin 133 FSB.

juin, learn something, there is no celeron with 133MHz FSB, the Tualatin Celerons (1.2 and 1.3GHz) use a 100MHz FSB, that's why they're slower.

What's the frequency, Kenneth?

Basically, if you want to support a Northwood, you need Socket 478.
