Ars Technica has details from the Intel Developer Forum where Intel released details of its next two generations of 45nm processor designs, codenamed Penryn and Nehalem.
Penryn is the 45nm shrink and design refresh of the current Core 2 architecture which will offer a 20 percent performance boost over the current 65nm products within the same thermal envelope. It will be available to the server market in November.
Nehalem is a new architecture that includes up to eight cores each handling two threads, an on-die memory controller, and direct connection among processors, the latter two items replicating what AMD does with its dual core Athlons. Later in 2009 Intel plans to shrink the Nehalem to 32nm.
