AMD has updated its Opteron rollout roadmap with an announcement of a quad-core processor for one-socket servers and workstations, and giving us a release date on the follow-up to its initial quad-core release, as well as its new mobile processor core. "That initial quad-core release will be followed in the first half of 2008 by the launch of Shanghai, its quad-core successor, according to Seyer. Shanghai is a code name for a processor that will feature HyperTransport 3.0, which provides high-speed chip-to-chip and board-to-board communications. Right now, the company's processors are using HyperTransport 1.0. Shanghai, according to an AMD spokesman, also will have shared L3 cache, a third bank of memory on the processor for storing instructions. He said it also will have DDR2 (double data rate) options, which is a memory industry standard. Budapest will be a quad-core Opteron offering for one-socket servers and workstations. It also will offer HyperTransport 3.0. It's scheduled for release in mid-2007, as is Barcelona."
