AMD is on track to release four processor models under its eagerly anticipated Phenom brand during Q4, it has been claimed. That's a quarter later than previous reports had suggested.

Reports by DigiTimes and VR-Zone have released speculative roadmaps that indicate Q4 will see the release of the Phenom FX-80, the dual-core Phenom X2 GS-6550 and two quad-core Phenom X4s, the GP-7100 and the GP-7000, with November touted as the earliest possible shipping date.

It was previously thought that three Phenom-branded processors would see the light of day in Q3, quad-core 65nm parts with four blocks of 512KB L2 cache and 2MB of shared L3 cache, with more chips following in Q4.

AMD has never publicly said when its Phenom processors will ship, so the release date hasn't slipped as such. But it certainly appears users won't be able to get their hands on the new chips as early as they might have hoped.

The FX-90 and 91, together with the X2 GP-6800, GS-6650, GE-6400, GE-6500 and GE-6600, are all now set to be launched in Q1 2008, it's claimed.
