CNET writes Intel is expected to announce details of its eight-core Nehalem-EX processor next week. This chip has 2.3 billion transistors and is capable of executing 16 threads, it will be launched by the end of this year or early 2010.
The 8-core "Nehalem-EX" Xeon processor is designed for servers that can use more than two processors (referred to as "sockets" in server argot). Currently, Intel is shipping Nehalem Xeon processors for servers with two sockets.
Nehalem is the same architecture used in Intel's Core i7 desktop processor line.
The Nehalem-EX is expected to become Intel's top-line Xeon processor. Currently, the six-core "Dunnington" processor, based on Intel's older Penryn architecture, is Intel's highest-performance chip for multi-processor servers.
