Itanium
®
processor and high-speed
inter/intra Cell cache-to-cache data transfer
At the heart of the Express5800/1000 series server is the
64-bit Dual-Core Intel
®
Itanium
®
processor, redesigned for
even faster processing of larger data sets.
The system has been equipped with the NEC designed chipset,
“A
3
”, in order to improve performance by utilizing, to its full
extent, the massive 24MB of cache memory that has been built
into the Dual-Core Intel
®
Itanium
®
processor
Technologies to increase cache-to-cache data transfer, such
as the VLC architecture and CCI, have been implemented
to maximize the performance for enterprise mission critical
computing.

EPIC architecture
In the EPIC architecture, parallelization is run at compile time,
allowing for maximum parallelization with minimal scheduling.

processor
Dual-Core, massive L3 cache and EPIC (Explicitly Parallel Instruction Computing) architecture
The Dual-Core Intel
®
Itanium
®
processor is Intel’s first production
in the Itanium
®
processor family with two complete 64-bit cores
on one processor and also the first member of the Intel
®
Itanium
®
processor family to include Hyper-Threading Technology, which
provides four times the number of application threads provided by
earlier single-core implementations.
With a maximum of 24MB of On-Die L3 cache, the Dual-Core Intel
®
Itanium
®
processor excels at high volume data transactions.
EPIC architecture provides a variety of advanced implementations
of parallelism, predication, and speculation, resulting in superior
Instruction-Level Parallelism (ILP) to help address the current
and future requirements of high-end enterprise and technical
workloads.
