AMD will ship its 65nm dual-core Athlon 64 X2 processors a week on Tuesday, it has been claimed. If correct, the 5 December debut apparently marks an acceleration of AMD's anticipated 65nm roll-out schedule.

AMD has been expected for some time to be preparing to ship the 65nm X2s, codenamed 'Brisbane', next month, with reports claiming such a move stretching back to May this year. Later reports had the chips' debut down as Q1 2007, but later in the year, the launch moved forward, to December.

Today, however, the Chinese-language Commercial Times put a specific date on the chips' debut and claimed the early December release comes sooner than anticipated. It suggested the acceleration was driven by Dell's processor demands.

Four Brisbanes are expected at launch: the Athlon 64 X2 4000+, 4400+, 4800+ and 5000+, clocked at 2.1GHz, 2.3Ghz, 2.5GHz and 2.6GHz, respectively. They're all TDP-rated at 65W and contain 1MB of L2 cache.

Q2 2007 is expected to see the arrival of further Brisbanes: the 65W, 2.7GHz 5200+ and the 76W, 2.8GHz 5400+, both with 512KB of L2 per core. Joining them will be three "energy efficient" Brisbanes: the 2GHz 3800+, the 2.1GHz 4000+ and the 2.2GHz 4200+. All three dual-core CPUs have two 512KB L2 caches and a 35W TDP. They'll be joined in Q3 2007 by the 2.3GHz 4400+. ®
