Today marks the end of support for Itanium's IA-64 architecture in the Linux kernel's 6.7 update—a significant milestone in the winding-down saga of Intel Itanium. Itanium, initially Intel's ambitious venture into 64-bit computing, faced challenges and struggled throughout its existence. It was jointly developed by Intel and HP but encountered delays and lacked compatibility with x86 software, a significant obstacle to its adoption. When AMD introduced x86-64 (AMD64) for its Opteron CPUs, which could run x86 software natively, Intel was compelled to update Xeon, based on x86-64 technology, leaving Itanium to fade into the background.

Despite ongoing efforts to sustain Itanium, it no longer received annual CPU product updates, and the last update came in 2017. The removal of IA-64 support in the Linux kernel will have a substantial impact since Linux is an essential operating system for Itanium CPUs. Without ongoing updates, the usability of Itanium servers will inevitably decline, pushing the (few) remaining Itanium users to migrate to alternative solutions, which are most likely looking to modernize their product stack.

Intel has unceremoniously, through a product change notification (PCN), discontinued the Itanium family of microprocessors. The Itanium 9700 "Kittson," which was released in 2017, is the final generation of Itanium, and its sales to new customers have stopped according to the PCN. The series has been marked "end of life" (EOL). Existing customers of Itanium who already have their IT infrastructure built around Itanium 9700 series, have an opportunity to determine their remaining demand of these processors, and place their "Last Product Discontinuance" order with Intel. The final LPD shipments would go out mid-2021.

With this move, Intel has cast uncertainty over the future of the IA-64 microarchitecture. IA-64 was originally conceived by Intel to replace 32-bit x86 at the turn of the century, as an industry-standard 64-bit processor architecture. AMD laid the foundation for its rival standard AMD64, which could go on to become x86-64. AMD64 won the battle for popularity over IA-64, as it maintained complete backwards-compatibility with x86, and could seamlessly run 32-bit software, saving enterprises and clients billions in transition costs. Intel cross-licensed it as EM64T (extended memory 64-bit technology), before standardizing the name x86-64. Itanium dragged on for close to two decades serving certain enterprise and HPC customers.

According to the International Data Corporation (IDC) Worldwide Quarterly Server Tracker, factory revenue in the worldwide server market decreased 4.0% year over year to $12.2 billion in the third quarter of 2012 (3Q12). This is the fourth consecutive quarter of year-over-year revenue decline, as server market demand continued to soften following a strong refresh cycle that characterized the market in most of 2010 and 2011. After declining in 2Q12, server unit shipments increased 0.6% year over year in 3Q12 to 2.1 million units. This was the 11th time in the past 12 quarters that server units have grown on a year-over-year basis.

On a year-over-year basis, volume systems experienced a 0.5% revenue decline. At the same time, demand for midrange and high-end systems experienced year-over-year revenue declines of 14.0% and 8.9% respectively in 3Q12. All three segments were impacted by difficult year-over-year compares combined with transitions in the technology refresh cycles.

In what could be the very first time two different machine architectures share a platform, future versions of Intel's Xeon and Itanium processors could be socket-compatible. Intel Itanium is based on the Itanium64 (IA64) machine architecture, while Xeon is x86-64 based. Intel plans to implement its common platform strategy with the next generation models of the two, that's "Kittson" Itanium, and "Haswell" Xeon.

This level of convergence could make it easier for companies to deploy select amounts of Itanium and Xeon processors in their data-centers, to suit specific tasks, and save money on buying common platforms for both. Itanium processors are typically preferred for in mission-critical environments, where there's close to zero margin for error (think military, medical, and space-exploration); while Xeon is good at handling heavy serial processing loads (think servers, database management, cloud). Introduction of the converged platform is expected in the 2013-2015 time range, using Xeon "Haswell" launch as a point of reference.

HP today strengthened its mission-critical Converged Infrastructure portfolio with innovative and enhanced HP Integrity systems, HP-UX software and services to triple performance, boost resiliency and deliver investment protection for critical workloads deployed into the next decade. Based on HP enhancements and the Intel Itanium processor 9500 series, transactions are processed up to three times faster than previous generations, while using 21 percent less energy. As a result, clients can realize a 33 percent savings in total cost of ownership (TCO).

Today's announcement delivers against HP's commitment to industry-leading innovations for the HP Integrity platform. With advancements in availability and reliability, HP's mission-critical Converged Infrastructure will continue to enhance established HP Integrity platforms supporting HP-UX, HP NonStop and OpenVMS operating systems. Over time, these advancements will cascade to mission-critical x86 platforms delivering a single, unified infrastructure for UNIX, Windows Server and Linux environments.

In an era of unprecedented growth in data usage, businesses require powerful computing solutions that can deliver scalable and resilient performance to run IT's most mission-critical applications. The new Intel Itanium processor 9500 series is more than twice as powerful as the previous generation, making it ideal for today's most demanding workloads, including business analytics, database, and large-scale enterprise resource planning (ERP) applications. Systems based on Intel's Itanium processors run in more than three-quarters of the World's Global 100 companies across industries such as aerospace, energy, life sciences and telecommunications. With the Intel Itanium processor 9500 series, these industries will benefit from a leap in performance and an increase in world-class reliability, availability and serviceability (RAS) capabilities.

Microsoft plans to gradually end support for the Intel Itanium IA64 architecture with this generation of Windows, SQL Server, and Visual Studio software. The Windows Server 2008 R2, SQL Server 2008 R2, and Visual Studio 2010, will be the last versions to support IA64. Mainstream support for IA64, for Windows Server 2008 R2 will end end on July 9, 2013, while in accordance with Microsoft Support Lifecycle Policy, extended support will last till another five years past 2013, ending on July 10, 2018. Till that time, Microsoft hopes that the industry will adapt itself extensively to the x86_64 (x64) architecture for enterprise hardware.

This change establishes x86_64 as the de-facto 64-bit computer architecture across all segments of computing, as far as Microsoft's market is concerned. A majority of IA64 users use the HP-UX operating system, with Microsoft Windows Server having a paltry 5 percent usage share. Having a small market share with IA64, Red Hat had last year, announced that it would end support for IA64 since the tiny userbase didn't justify having continued development of RHEL for IA64. For consumer operating systems, Microsoft ended IA64 support with Windows Vista, leaving only Windows Server versions with it.

Intel Corporation today previewed a new Intel Xeon processor codenamed "Nehalem-EX." The processor will be at the heart of the next generation of intelligent and expandable high-end Intel server platforms, which will deliver a number of new technical advancements and boost enterprise computing performance.

In production later this year, the Nehalem-EX processor will feature up to eight cores inside a single chip supporting 16 threads and 24MB of cache. Its performance increase will be dramatic, posting the highest-ever jump from a previous generation processor.

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.

Underscoring strong momentum and industry support, Intel Corporation today unveiled Dual-Core Intel Itanium Processor 9100 series processors. Built for managing high-end applications and armed with advanced features that improve reliability and reduce power consumption, the 9100 series accentuates the ongoing shift from proprietary RISC products to the choice offered by Itanium-based servers. The 9100 series represents the sixth generation of Itanium chips, with three future generations under development.

Intel has revealed its latest Montvale-based processor line. The new Montvale-based processors (which will replace the current Montecito-based processors) retain the Itanium 2 name, but with a different processor number. Montvale-based processors will carry the 9100-series processor number to differentiate from the Montecito-based 9000-series. The new Itanium 2 9100-series has minor upgrades over the 9000-series such as a faster 667 MHz front-side bus and the demand Based Switching with Enhanced Intel Speedstep Technology that allows the higher-end Itanium 2 9100-series models to enter a low-power state when idle.
