AMD Confirms Double Sourcing Athlon II X4s Processors
AMD sent us an e-mail confirming that they are building AMD Athlon II X4 processors that are based on both the new ‘Propus’ 169mm die and the older Deneb 258mm die size. It seems they have totally disabled the L3 cache on any Deneb die that makes it into an Athlon II X4 processor though. It will be interesting to see if consumers will be able unlock the L3 cache on any Deneb based AMD Athlon II X4 processors by simply enabling Advanced Clock Calibration (ACC). Companies like AsRock have been marketing how their boards unlock ‘hidden’ features like this, so time will tell.
Ive recently been made aware that AMD chose to manufacture some Athlon II X4 processors on the Deneb processor die as well. (Deneb is the die Phenom II is manufactured on) In that case, of course, Denebs L3 is disabled so that the defining processor specifications remain unchanged for Athlon II X4 models. Just wanted you to be aware of that fact.
