AMD disclosed updated performance projections for its upcoming native Quad-Core AMD Opteron™ processors, code-named ‘Barcelona.’ The new Barcelona projections are based on the latest SPECcpu2006 benchmarks and show that AMD expects to have up to a 50 percent advantage in floating point performance and 20 percent in integer performance over the competition’s highest-performing quad-core processor at the same frequency.

Marking with the fourth anniversary of the launch of the AMD Opteron™
processor and AMD64 technology, AMD (NYSE:AMD) today announced widespread
availability and pricing for the performance-leading AMD Opteron Model 2222 and
8222 SE x86 dual-core server processors. The new processor, which is available
in several platform configurations today from tier one OEMs, is designed to
deliver performance leadership in the most critical server functions including
Web serving, scalability and floating point calculations.

AMD also disclosed updated performance projections for its upcoming native
Quad-Core AMD Opteron™ processors, code-named ‘Barcelona.’ The new Barcelona
projections are based on the latest SPECcpu2006 benchmarks and show that AMD
expects to have up to a 50 percent advantage in floating point performance and
20 percent in integer performance over the competition’s highest-performing
quad-core processor at the same frequency. These results, as well as the latest
benchmark tests, based on AMD Opteron Model 2222 and 8222 SE processors can be
found at www.amd.com/opteronperformance.

“Today’s announcement further demonstrates AMD’s commitment to delivering
excellence and represents continued innovation along the customer-directed path
we blazed four years ago; we provide the complete x86 processor architectural
standard others in the industry are trying to emulate and we have planned a
seamless upgrade path to native quad-core for delivery to the market in
mid-year,” said Randy Allen, corporate vice president, Server and Workstation
Business, AMD. “With our native quad-core technology, AMD continues to build off
of a consistent architecture and will deliver more than just four processing
cores. We believe our enhanced architecture will deliver increased performance
and performance-per-watt without forcing disruptive platform transitions.
Investment protection continues to be a central focus of our customer-centric
design principles.”

In commemoration of the four-year anniversary of the AMD Opteron processor,
visitors can go to www.amd.com/opteronanniversary for a glimpse of what the
world may have looked like had there been no AMD Opteron processors and no x86
server processor choice.

Performance-Per-Watt Leadership
As performance-per-watt also continues to be a critical issue for IT
decision-makers in addition to raw performance, AMD recently launched the AMD
Platform Power Calculator. By leveraging this tool, customers can compare
estimated power consumption of servers based on AMD Opteron processors that span
all thermal envelopes, 68, 95 and 120 watt, and similar servers based on
dual-core processors from the competition. To learn more about how AMD Opteron
processors help you get more performance using less power, visit http://enterprise.amd.com/Flash/PlatformPower.html.

x86 Virtualization
This balanced approach to system architecture is why the combination of AMD
Virtualization™ technology and Direct Connect Architecture provides enhanced
virtualization performance. Multiple operating systems running on a single
server compete for physical resources, which can exacerbate the performance
bottlenecks inherent in other architectures and slow response time for users.
Therefore, legacy processor architectures based on a traditional front-side bus
are simply not ideal for today’s virtualization needs.

Widespread Hardware Partner Support
Today, the industry’s leading original equipment manufacturers (OEMs) announced
continued support for AMD Opteron processors: “AMD’s focus on stability,
longevity and performance delivers value to customers who rely on AMD Opteron
processor-based HP ProLiant servers and blades to run their business,” said Paul
Miller, vice president, marketing, Industry Standard Servers and BladeSystem
Division, HP. “HP’s leadership in delivering a broad portfolio of x86 servers
and blades based on the AMD Opteron Model 8222 SE and the upcoming ‘Barcelona’
processor positions customers to achieve maximum performance of their
business-critical applications and virtualize their networks.”

“As the first company to embrace AMD Opteron processors in 2003, we are
gratified to see the impact AMD has had in the datacenter over the last four
years. During that time, IBM and AMD have both benefited from our strong
alliance, not only at the system level, but also through our technology
partnership that is helping to drive the manufacturing of the next generation of
AMD processors,” said Alex Yost, director, IBM System x. “AMD Opteron processors
have been integral to some of our most innovative recent product introductions,
including our scalable snap-on blades and Xcelerated Memory Technology. We look
forward to continuing our track record of collaborative innovation later this
year when AMD’s quad-core ‘Barcelona’ processors are introduced.”

“AMD and Sun’s partnership has been instrumental in helping Sun continue to
build tremendous momentum with its x64 business,” said Lisa Sieker, vice
president of marketing, Systems Group, Sun Microsystems. “Through extensive
collaboration, we have been able to optimize systems for the AMD Opteron Model
2222 and 8222 SE processors, in addition to systems based on the upcoming launch
of Barcelona. We’re excited to continue this strategic partnership through our
broad line of x64 systems and the Solaris™ 10 Operating System, delivering the
breakthrough performance and architecture of AMD Opteron processors.”

“We’re committed to helping customers simplify their IT operations and overcome
infrastructure constraints and lifecycle costs so they can focus on what’s
important – growing their business,” said Jay Parker, director of PowerEdge
Servers, Dell Product Group. “Solutions like the AMD-based PowerEdge 2970 and
PowerEdge Energy Smart 2970 servers give customers the performance they need
while helping to reduce energy consumption, complexity and overall lifecycle
costs through a simplified upgrade path to multi-core platforms.”
