Cray XT5 Series of Supercomputers Now Available With Six-Core AMD Opteron(TM) Processors

SEATTLE, WA, Jun 01 (MARKET WIRE) --
Global supercomputer leader Cray Inc. (NASDAQ: CRAY) today announced that
the Cray XT5(TM) and Cray XT5m(TM) supercomputers are now available with
the new Six-Core AMD Opteron(TM) processors, formerly code-named
"Istanbul." With this latest release of AMD's next generation of
processors, the Cray XT5 and Cray XT5m are the first Cray systems to
feature 12 cores per computational node. This collaboration with AMD
reaffirms Cray's industry-leading position in creating petascale-class
systems.

"We expect the Six-Core AMD Opteron processor will dramatically improve
performance and efficiency for Cray customers upgrading their current Cray
XT systems, as well as provide industry-leading scalability and
performance density for customers that purchase new Istanbul-based
systems," said Barry Bolding, Cray's vice president of scalable systems.
"We have been preparing for the arrival of AMD's new processors for some
time, so that current Cray customers can easily upgrade from their
existing dual- or quad-core processors and experience the benefits of
dramatically increased performance, versatility and energy optimization."

The Six-Core AMD Opteron processor will provide more than a 30 percent
performance per watt improvement over previous generations of AMD Opteron
processors.

"This next generation of AMD processors will allow researchers and
scientists to continue maximizing the computational power of their Cray
supercomputers to address some of the world's most complex and
sophisticated problems," said Patrick Patla, vice president and general
manager, Server and Workstation Division, AMD (NYSE: AMD). "Combining the
upgradeability of the Cray XT line of supercomputers with our new Six-Core
AMD Opteron processors creates a perfect fit for high performance
computing systems that are tasked with ever-increasingly complex computing
challenges."

About the Cray XT(TM) Supercomputer Series

As the world's most scalable Linux supercomputer, the Cray XT product line
combines unprecedented sustained application performance with exceptional
manageability and reliability, and lower cost of ownership for customers.
Using powerful AMD Opteron(TM) processors, the Cray XT line is optimized
for memory-intensive and/or compute-biased workloads. The successful Cray
XT product line features ECOphlex(TM) technology -- packaging and design
features that promote energy savings along two dimensions: by enabling
greater system density and by reducing the need for expensive air cooling
and air conditioners. Additionally, the Cray Linux Environment(TM) enables
optimized performance across a broader range of applications.
