Future Processor Generations
Future Intel Itanium processors already in development are being
designed to provide binary-compatibility and socket-compatibility with
the Intel Itanium processor 9300 series.
• Next-Generation Intel Itanium processor (code-name Poulson):
This processor will be based on a new ultra parallel microarchitecture
and will be manufactured on Intel’s 32 nm process technology. It will
include more cores, support more software threads and run at a
higher clock frequency. It will also include new RAS features and
support a number of instruction-level advancements.
• Future Intel Itanium processor (code-name Kittson): This future
Intel Itanium processor is in definition today and can be expected to
provide additional capabilities.
Conclusion
The Intel Itanium processor 9300 series delivers a major leap forward
in performance and scalability for Itanium-based servers, along with
more and better RAS features and improved support for virtualization
and dynamic partitioning. Systems based on this processor provide an
exceptional combination of scalable performance and high availability,
along with the flexibility to support diverse operating systems, appli-
cations and data center environments.
This new processor provides twice as many cores as its predecessor,
more on-die cache (30 MB versus 27 MB), up to nine times the inter-
connect bandwidth and up to six times the memory bandwidth. With
these enhancements, it can be expected to deliver more than double
the performance (or more) for many applications. It also scales more
effectively in large multiprocessor systems. Interconnect and memory
bandwidth increase automatically as more processors are added,
and memory capacity is up to eight times greater than systems built
with the previous-generation processor. System design is also simpli-
fied. Glueless designs are supported up to eight sockets and much
larger systems can be built by aggregating these four- or eight-socket
“nodes” using vendor-supplied chipsets.
New Intel Turbo Boost Technology and an enhanced version of
Demand Based Switching (DBS) provide better control of performance
versus energy efficiency. DBS can now be used to throttle frequency
as well as voltage to further reduce energy conservation during light
workloads. Intel Turbo Boost can be used to dynamically increase clock
frequency for certain workloads, to maximize performance while stay-
ing within the processor’s thermal design limit.
The Intel Itanium processor 9300 series also extends the mainframe-
class RAS features of its predecessor. Error detection, correction and
avoidance are extended and/or improved across all key components
and advanced support for partitioning, virtualization and resource
management have been integrated directly into the processor to
provide simpler and more consistent vendor implementations.
With these advancements, systems based on the Intel Itanium proces-
sor 9300 series will provide even more powerful, exible and robust
support for today’s most demanding and mission-critical applications.
Organizations will also be able to scale the performance and capacity
of these systems for many years to come through component upgrades,
using future Intel Itanium processors that are in development today
and are being designed to provide both binary compatibility and socket
compatibility.
