Intel preps 6-core Xeon ‘Dunnington’ processors

“Late last month in Austria, Intel presented Sun with roadmaps discussing details of its upcoming server platforms, including the fairly secret Xeon Dunnington and Nehalem architectures. Unfortunately for some, this presentation ended up on Sun’s public web server over the weekend,” Kristopher Kubicki reports for Daily Tech.

“Dunnington, Intel’s 45nm six-core Xeon processor from the Penryn family, will succeed the Xeon Tigerton processor. Whereas Tigerton is essentially two 65nm Core 2 Duo processors fused on one package, Dunnington will be Intel’s first Core 2 Duo processor with three dual-core banks,” Kubicki reports. “Dunnington includes 16MB of L3 cache shared by all six processors.”

“Intel’s slide claims this processor will launch in the second half of 2008 — a figure consistent with previous roadmaps from the company,” Kubicki reports.

  1. With core count and memory sizes starting to increase fairly smartly, does anyone know how well 64 bit Vista scales to utilize them? I would expect the UNIX based OS X system to have a distinct edge in scaling performance over the Windows system, but have no information to support this. I’m wondering where the point of diminishing returns is for Vista and OS X, and am thinking that OS X may have a good message here. Of course how well the applications can make use of multiple cores is a whole other topic.
