[Ars]AMD's Barcelona to hit server racks in April

After months of setbacks and delays, AMD's K10 Barcelona architecture is finally ready for server-level deployment. The new Opteron processors will be based on the B3 silicon revision, and will correct the TLB erratum that effectively wrecked Barcelona's earlier September launch. The Sunnyvale-based manufacturer has announced that it expects servers based on its B3 silicon revision to ship in April. HP, Dell, and IBM are all expected to launch servers over the next few months, but HP in particular has something big in the pipeline.

On Monday, HP announced the ProLiant DL785, its largest x86 server to date. The DL785 will be available in both four-processor and eight-processor configurations, and will use AMD's new B3 quad-core Opterons for a maximum of 32 processor cores in a single server. Those 32 cores won't lack for memory; the DL785 will launch with support for up to 256GB of RAM, with a 512GB maximum density once 8GB DIMMs become available this fall.
Design wins like this are particularly important for AMD as the company effectively relaunches a product line that should have been available six months ago. Substantially higher clockspeeds than the 2GHz AMD debuted at Barcelona's September launch could improve B3's overall marketability, but neither HP nor AMD has given any guidance on what frequencies to expect.

AMD's VP of commercial business, Kevin Knox, was, however, willing to discuss the aftermath of the TLB erratum with Computerworld, as well as share his thoughts on Intel's upcoming six-core Dunnington processor (currently due in the second half of this year). According to Knox, the work the company did in repairing the B2 TLB erratum will aid AMD in future processor design.

Knox isn't so sure, however, that Dunnington will be a compelling product. "Six cores is interesting. Again, I'm not convinced there's a gigantic market of applications that want to exploit that number," Knox told Computerworld. "We still believe we're going to be extremely competitive. When you look at the architecture things we've done, like hyper transport, that will make us extremely competitive, added to the fact that we'll have quad-core to compete against quad-core."

While it's true that the number of applications optimized for n number of cores drops as n increases, businesses and institutions with workloads that do benefit from processors with more than four cores will probably tend to prefer Dunnington (or Dunnington-compatible) hardware. The theoretical results of a Dunnington match-up, however, are the least of AMD's concerns. Intel's 45nm Harpertown Xeons have already ridden into town, and they're the competition AMD's revised Barcelona core will have to face as best it can.

Some good news for AMD.

AMD needs this, and i think they will make a lot of money off of it.

Thats why AMD uses Hypertransport, and why Intel has developed something similar. The ability to have a large amount of processors working together without being bandwidth starved is always good. However AMD's success will be based on their price, and what people will use it for (beleive it or not, the K10 IS faster than the Core 2 in some server applications ).
