AMD's latest official statements regarding versions of processors based on 45nm process technology is that shipments should kick off in the second half of this year. The company has yet to disclose a more precise time frame, and recent rumors have suggested that we may not actually see 45nm Phenoms hit stores until the fourth quarter—roughly a year after the launch of Intel's first 45nm desktop CPU.
However, the folks at Fudzilla have published a new report that casts doubt on those rumors. According to Fudzilla, AMD has informed its staff that 45nm Stars processors will launch in both the third and fourth quarters of 2008. If true, that statement means we could see 45nm Phenoms start rolling out anytime between July and September. Fudzilla says the 45nm Phenom lineup will include Deneb FX and Deneb quad-core models with both L2 and L3 cache as well as Propus quad-core models with only L2 cache. Triple- and dual-core 45nm Phenoms aren't due until early 2009.
Judging by a presentation recently leaked by Sun, Intel anticipates that AMD's 45nm quad-core Opterons will run at up to 2.8GHz, so similar speeds on the Phenom side should be possibile. In that case, Phenom could put up a decent fight against Intel's 45nm Core 2 Quads.
