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.

K8 and Conroe are just evoluntionary Pentium Pro/P2/P3 designs. There's nothing Revolutionary about K8. Netburst was just a weird design to wow the buyer with great megahertz numbers. Intel thought they could design the long pipeline to be very intelligent wrt instruction ordering and achieve great performance but that never happened. The ultra long pipelined Prescott was supposed to be the pinnacle of this effort but it was a total flop, but boy did Intel ever learn a lot about manufacturing processes with it. It catapolted them to where they are today. Their manufacturing processes are the absolute best. Wait till they fine tune their high k metal gate 45nm process (something AMD do not even have in the works). It will be something to behold, I'm sure.

AMD need to get some of the Intel Mojo in their 65nm process. I suspect it's mostly a question of dinero standing in the way of their success right now. And that's too bad, because it doesn't seem as though they'll be earning a whole lot any time soon.

AMD and IBM are working on HKMG's actually, and we MIGHT see them by the end of next year.

That's good news. I've only heard that IBM had high k 45nm but that AMD were not interested (in paying for it, probably). I do know with certainty that AMD's current 45nm effort is of the low k gate variety.

It's very good to hear that IBM and AMD are working on high k together. I hope AMD lessen their focus on a single die quad and concentrate their efforts on dual core and dual die quad core chips. From a manufacturing standpoint, this seems to make sense, and performance does not appear to be a huge issue (Kentsfield > Phenom).

good post. The first round of AMD 45nm will indeed be SOI, and they are supposed to switch over to HK after they release and get the 45nm process working fairly well. It probably will not be until 09 until we see it, but they are working on it.
