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.
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
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.
chips will be based on the Socket AM2 interface. These processors are compatible with AMD's AM2+ socket designated for Phenom processors.

The Tualatin was actually very poor at clock speed ramping, it was more of a test of the new process node that would eventually be used for the Pentium 4 Northwood, the Willamatte still used the same fabrication nodes as the Pentium 3 coppermine, the other notable thing is, that the Celeron Tualatin actually performed about the same as the Coppermine clock for clock (Even while it had a 33% advantage in bandwidth).
Besides the Pentim 4 wasn't all that bad, think of it like this.
Intel Used the Pentium 3 Tualatin, Retrofitted it with the Pentium 4's Front side bus, Advanced tree predictor, Doubled/Quadrupled the cache and made it more energy efficient, and extended/improved the pipeline and called it a Pentium M, which is what our new beloved Core 2 Duo's are all based on, which clock for clock slaughtered the Pentium 4.

Yes, while it had one half to one quarter of the L2 cache. If anything, that's a testament to the versatility of the P6 core.
And why couldn't Intel have done all of that whithout the Pentium 4?
