DAAMIT, the Necromancer
AMD plans to keep "Brisbane" around, releases new chips based on it
Things at AMD may have gone from bad to worse with the lackluster Phenom launch in late November. Not only did Phenom fail to appeal to professional reviewers, but the company ended up removing one third of its CPU lineup just after the big day.
Last week AMD CEO Hector Ruiz vowed that the company would stop hemorrhaging cash and return to profitability soon. "That is our number one goal right now," Ruiz said in a conference in Bangalore.
Making a profit at AMD apparently means refocusing on its older K8 architecture. The company will introduce eleven 65nm K8 processors over the next two quarters. By comparison: AMD launched two quad-core K10 Phenom processors in November with three more scheduled over the next two quarters. Two tri-core Phenom processors will follow in March 2008.
Essentially, AMD will move any remaining Athlon 64 processors from the 90nm node to the 65nm node, with a few new frequency and TDP variations.
The AMD Athlon 64 X2 5600+ will be the first to jump on the new 65nm K8 bandwagon with a 65W TDP. The previous Windsor-based chip of the same featured an 89-Watt TDP. AMD will also add 100 MHz to the core frequency of the Athlon 64 X2 5600+, now rated at 2.9 GHz. Total L2 cache will be halved in the move to the Brisbane core, and the updated Athlon 64 X2 5600+ chips will feature only 1MB of L2 cache. Availability of these processors is scheduled for Q1 2008.
AMD's higher-end Athlon 64 X2 6400+ and Athlon 64 X2 6000+ will both be discontinued.
AMD will also update its "Energy Efficient" series and will release three new chips, the AMD Athlon 4850e, Athlon 4450e, and Athlon 4050e in Q2 2008. All of the new offerings will be based on AMD's Brisbane core and will feature a 45-Watt thermal envelope. AMD's current energy efficient "BE-2xxx" series will be phased out at that time. Respectively, the new chips will run at 2.5GHz, 2.3GHz and 2.1GHz.
All new Brisbane chips will be based on the Socket AM2 interface. These processors are compatible with AMD's AM2+ socket designated for Phenom processors

EDIT.: ARS remembers a few things:
One other thing to keep in mind is that while Phenom's current problems undoubtedly have something to do with the firm's renewed interest in K8, a transition from 90nm to full 65nm production was virtually guaranteed at some point. Starting in the first quarter of 2008, AMD's Fab 30 will undergo a complete facility upgrade, including a shift to 300mm Savewafers and 45nm process technology. All of AMD's 90nm CPUs are currently produced in Fab 30, and although the facility will continue to produce processors while under construction, its 90nm production lines obviously aren't going to stay open forever.
It's in AMD's best interests to move production of the K8 series over to 65nm, regardless of Phenom's competitive status, but it's unfortunate that K10's current situation paints the act with an air of desperation. Ultimately, there's not much AMD can do to improve K8's performance vs. Conroe or Penryn—and focusing on power efficiency can only take the company so far.
