During the International Solid State Circuits Conference this week, Intel is set to unveil a range of new technologies, including the
low-power Silverthorne and a new two-billion transistor, quad-core Itanium microprocessor codenamed Tukwila. The first version of Tukwila is expected to arrive in the second half of this year, and will replace Intel's previous dual-core sever chip, the 9100 series codenamed Montvale. The Montvale was based on Intel's 90nm process, while the Tukwila is based on a 45nm process. The Tukwila processor is expected to have 30MB of cache, along with Reliability, Availability, Serviceability (RAS) features including a circuit design that has been hardened to resist soft errors - which reduces the probability of a system crash. Like its predecessor, the new Tukwila Itanium processor will be aimed at the enterprise and server space. Intel's successor from the Tukwila, the "Poulson" is expected sometime between 2010 and 2011.
