A is for Northwood?

I just have a quick question. I'm sorta...naive when it comes to newer intel cpu's so I was wondering, how do you tell the difference between a northwood and a normal p4? Am I right by assuming that the A in 1.6A means it's a northwood?

Thanks in advance guys for the help ^_^
Yep. 1.6 is Willamette, 1.6A is Northwood. Same goes for 1.8 and 2.0. The 2.2 and 2.4 speed chips are available with the Northwood core only, so there will be no "A" after them.
Ok, thanks for the info everyone!

Intel has caught my attention again. It's really nice having two very competitive companies making GOOD products now. The old p4's blew (opinion). :D
Intel traditionally adds an "A" to the newest processor if there happens to be two of the same speed. Like the Celeron 533a or the P-4 Northwood 1.6a. If you want a Northwood, make sure it says 512k cache.
