AMD unveils new x86 microarchitectures

"Advanced Micro Devices is unveiling the technical details of two new microprocessors, "Bobcat" and "Bulldozer," during the Hot Chips conference at Stanford University. The designs, addressing low-power netbooks and desktops on the one hand and high-performance PCs/servers on the other, are expected to begin sampling later this year.

"Bobcat and Bulldozer mark the first time in nearly seven years that AMD has updated the microarchitecture of processing cores. While AMD engineers are detailing technical components of these two chips at the Hot Chips conference, the company is not expected to reveal any information about clock speed, pricing or specific release dates.

"However, Bobcat and Bulldozer should begin sampling to AMD's OEM partners by later this year, with sales beginning in early 2011. "
