Product Features
The Intel
®
Itanium
®
2 processor is designed to address the needs of high-performance servers and workstations.
The Itanium architecture goes beyond RISC and CISC approaches by employing Explicitly Parallel Instruction
Computing (EPIC), which pairs extensive processing resources with intelligent compilers that enable parallel
execution explicit to the processor. The processor’s large internal resources combine with predication and
speculation to enable optimization for high performance applications running on multiple operating systems,
including versions of Microsoft Windows*, HP-UX* and Linux*. The Itanium 2 processor is designed to support
very large scale systems, including those employing thousands of processors, to provide the processing power and
performance head room for the most demanding enterprise and technical computing applications. SMBus
compatibility and comprehensive reliability, availability and serviceability (RAS) features make the Itanium 2
processor ideal for applications requiring high up-time. For high performance servers and workstations, the
Itanium 2 processor offers outstanding performance and reliability for today’s applications and the scalability to
address the growing e-business needs of tomorrow.
