Intel® Itanium® 2 Processors Get Faster Bus Architecture
Intel Corporation today introduced two Intel Itanium 2 processors which deliver better performance over the current
generation for database, business intelligence, enterprise resource planning and technical computing applications.
For the first time, Itanium 2 processors have a 667 megahertz (MHz) front side bus (FSB), which connects and transfers
data between the microprocessor, chipset and system’s main memory. Servers designed to utilise the new bus are expected
to deliver more than 65 percent greater system bandwidth over servers designed with current Itanium 2 processors with a
400 MHz FSB. This new capability will help set the stage for the forthcoming dual core Itanium processor, codenamed
‘Montecito,’ which will feature the same bus architecture.
“Intel continues to bring new capabilities to the Itanium architecture, evolving the platform to further improve
performance for data intensive tasks,” said Kirk Skaugen, general manager of Intel’s Server Platforms Group. “Looking
forward, we are coming up to the next major milestone for the Itanium processor family – dual-core server platforms
based on Montecito. We are extremely excited about the customer and industry feedback we are getting, and the
preliminary performance results we are seeing on Montecito-based systems will further expand Itanium’s leadership in its
targeted market segments.”
Itanium-based servers continue to make strides in three target market segments: RISC replacement, mainframe migration
and high-performance computing. Today, more than 40 percent of the Global 100 corporations have deployed Itanium-based
servers and 79 of the TOP500 list of the world’s fastest super computers are powered by Itanium processors. The
ecosystem continues to grow with more than 3,600 applications available, while eight of nine RISC vendors and six of
seven mainframe vendors sell mainframe-class Itanium-based servers.
The improved front side bus bandwidth allows for 10.6 gigabits of data per second to pass from the processor to other
system components. In contrast, the current generation 400MHz FSB transfers 6.4 gigabits of data per second. The ability
to move more data in a very short period of time is critical to compute intensive applications in the scientific, oil
and gas, and government industries.
Hitachi, which will adopt the new Itanium 2 processors with the 667 FSB into new Hitachi BladeSymphony* servers coming
in the next 30 days, has also designed a chipset (the communications controller between the processor and the rest of
the computer system) to take advantage of the new bus architecture.
Platforms using Montecito are expected to deliver up to twice the performance, up to three times the system bandwidth
and more than 2 1/2 times as much on-die cache as the current generation of Itanium processors. While boosting
performance, Montecito is expected to also deliver more than 20 percent lower power than previous generations of Itanium
processors due to new technologies for power management. Montecito will also have Intel Hyper-Threading technology,
enabling four times as many threads as the current generation.
The Intel Itanium 2 processor at 1.66GHz with 9MB of cache with 667 FSB is available for US$4,655 in 1,000-unit
quantities. The Intel Itanium 2 processor at 1.66GHz with 6MB with 667 FSB of cache will be available for US$2194 in
1,000-unit quantities.
Intel, the world’s largest chip maker, is also a leading manufacturer of computer, networking and communications
products. Additional information about Intel is available at www.intel.com/pressroom.
