Allendale core

[fzkl]

I remember reading that the E6300 and the E6400 were the allendale core. Then intel launched the E4xxx series which were also called the Allendale. My question is, did intel start calling E6300 and E6400 as conroe's since launching E4xxx? I am having an argument with a colleague that the E6300 and E6400 were never called Conroe's. He claims that intel started calling E6300 and E6400 as Conroe since the launch of E4xxx. Trying to figure out if I am wrong.

Thanks.

Allendale - 2MB Cache
Conroe - 4MB Cache.
E6300 & E6400's were in fact conroe's w/ 1/2 the cache disabled therefore making them Allendales.
E6320 and E6420's are chips w/ their full (Conroe) caches enabled.

At launch, the E6300 and E6400 were Conroe chips with half of their cache disabled. Later, Intel introduced E6300s and E6400s that were Allendales, and physically only had half as much cache present. IOW, these were different (but functionally identical) products that were sold under the same model number. It was not simply a change in codename; Intel doesn't refer to released products by their codename anyway.

You can get the sSpec and steeping numbers here, if you like.

What happened to the virtualization support while going from Conroe to Allendale? Those Intel butchers chopped off more than a pair of L2s. And how did they chop off the virtualization support anyway?

The E6300 and E6400 Allendales still have virtualization support. On the lesser (E4xxx) Allendales, the virtualization extensions are disabled in microcode.
