Quick Question on P4. Thanks

[sweetca]

Hi, everyone says buy the Pentium4 1.6 or 1.8A. How do I know which is A? Is it the one with socket 478 or socket 423? Or is it based on something else? Thank You

Its socket 478. The A denotes 512K cache. it should say 1.6A in the description and also 512K cache if it is mentioned.

The 478 pin version is the "A" version and should be a Northwood.

 

[bwass24]

The A processors are based on the .13 micron process, have 400mhz FSB speed and have a 512k on chip cache.

see here as an example.
The older P4 1.6 is listed as 1.6 with 256 K while the 1.6A is listed with 512K.

Ok, I think he has got the point.

While it's true that all Northwoods use S478, not all S478 P4's are Northwoods. Intel also makes Willamette (.18µ/256k L2 cache) S478 chips.

Thank you everyone for the informative replies.

Greatly appreciated

Stay clear of the Pentium 4's with only 256k L2 cache...
