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.

RE: AMD's new Sempron

Don't get me wrong, guys. I love AMD and have been a loyal customers of theirs since the K6-2 days. However this Barcelona bug is a serious misstep. Since Intel has started this "tick-tock" practice, AMD is going to have to make some big improvements in the theoretical K11 to even come close to the offerings Intel will have.
Think about this: Nehalem is going to be the Conroe redesign with 4 cores on die that's coming out the end of next year. I'm sure they'll use the same trick they're using now to put 4 + 4 cores communicating through the FSB on one cpu. Plus I hear that they're going to be bringing back hyperthreading technology back on the high end Nehalem chips. So that roughly means 16 listed cores for the Intel powered system to use.
Then what happens if Skulltrail starts selling and they make a version of that chipset for Nehalem. That's a "possible" 32 listed cores on your machine. (This will be 2009's newest Apple Macintosh High End Workstation... you heard it here first. Mac fans will be proud.)
... but AMD can't even get 4 cores working properly. And who's going to bother with 3 cores? And they just killed their enthusiast package.
I know that there isn't a large portion of software that can successfully use more than 4 cores for now. But as more processing cores become available, software developers will find a way to scale to it. Once that happens, Intel's going to be getting all the kudos and AMD is going to have to build up again to try to be competative. Or they finish the bulldozer all-in-one platform they've been talking about and show how great and simple those can be. But no matter how you slice it, AMD is going to have an uphill battle to fight with Intel to win back the performance crown.
2nd thing about Via, I don't believe their angle is EVER going to be performance. They're way outclassed for that. From what I understand the C7 line has all the power of a PIII of equal or lesser clock speed. They make for great e-appliances, web surfers, and eco-friendly open home file servers (assuming you're not worried about raw transfer speed). But I'm going to go out on a limb to say they're never going to be a #1 performer ever as long as Intel and AMD are in the market. I like their philosophy though and would be inclined to buy their product if they could keep the power consumption low while offering more expandability to their boards (more PCIe, 4 or more SATA 3GB connections, and so on). If they could make the next "conroe" sized leap in performance while keeping consumption down (maybe the C8 line will do this), these would be the bomb for laptops.
But that's my opinion.
