Intel just internally released some documentation about
Conroe-L BIOS specifics. Conroe-L, as we have previously
disclosed on DailyTech, is a single-core version of Conroe for value
Intel documentation claims that Conroe-L is not part of the immediate
Core 2 family processors, but part of an "extended family"
instead. Conroe and Woodcrest are single-die CPUs with two
cores per CPU. Kentsfield, Clovertown and Tigerton have
two dice per package, but are still considered part of the same family as Conroe
and Woodcrest: the processors use the same signatures. Conroe-L
apparently has a different processor signature and different model number, but
uses the same processor family identification.
The main difference between Conroe-L and the rest of the Conroe family,
according to older Intel roadmaps, is the fact that Conroe-L will only
be a single core processor. Whether or not this means one core has been
disabled is not specified yet, though it is important to note that the Core 2
architecture has a shared cache -- meaning if one core is disabled it does not
mean half of the processor cache is disabled.
Intel's latest roadmap still has Conroe-L slated for a Q2'07
launch. The Core 2 Duo version of Conroe is expected to start
shipping on the 23rd of
July, with the embargo lift shortly after.
