The latest rumor doing the rounds is that AMD's Athlon X2 may replaced by a dual-core K10 by the end of the first quarter of 2008. This is just a rumor, but we've been expecting AMD to transition their dual-core offerings from the now 'old' K8 designs to the newer K10 for some time.
“AMD will launch a new series of dual-core products based on its next-generation architecture, Athlon 6000, in the later half of second quarter next year. First to launch will be the Athlon 6250 and 6050, the sources revealed. Although the core frequencies of the two CPUs have not been set yet, they will adopt 1MB L2 cache and 2MB shared L3 cache, the sources added.”
By 1 MB L2 cache, we're fairly sure that both cores will have 512 KB for a total of 1 MB.
