AMD LAUNCHES AMD OPTERON(tm) 100 SERIES PROCESSORS WITH ECC UNBUFFERED MEMORY SUPPORT

SUNNYVALE, Calif., - Aug. 2, 2005 - AMD (NYSE:AMD) today announced
general availability of the AMD Opteron(tm) 100 Series processors that
now feature error-correcting code (ECC) unbuffered memory support. Based
on overwhelming customer demand in an increasing number of critical
markets for one-way servers and workstations, AMD is expanding the types
of memory supported by the AMD Opteron 100 Series processors. This new
type of memory support is now the standard for the 100 Series.

AMD will continue to deliver AMD Opteron 100 Series processors using
registered memory to existing customers that require them; including
customers who are designing high-end products based on the AMD64
embedded processor roadmap.

"Based on feedback from our customers, we have enhanced the AMD Opteron
processor roadmap by providing our customers more choices for the
technology they demand within an infrastructure that best suits their
needs," said Marty Seyer, corporate vice president, Commercial and
Performance Computing, Microprocessor Solutions Sector, AMD. "Adding ECC
unbuffered memory support to AMD's award-winning AMD Opteron 100 Series
processors with Direct Connect Architecture, is going to enable our
customers to offer even more compelling 1P server and workstation
solutions, while helping to reduce their overall solution costs. This is
another example of the innovative and responsive approach to customers
that has resulted in more than 75 of the top 100 of the Forbes Global
2000 enterprises using AMD64 technology."

Sun Microsystems, Inc., the first to use the new AMD Opteron 100 Series
with ECC unbuffered memory support, recently, announced the Sun Ultra 20
Workstation, based on the new processors. The Sun Ultra 20 Workstation
entered the marketplace with a new world record result on OCUS
benchmark, a performance measurement of graphics oriented MCAD
application - Pro/ENGINEER-based on results published at
http://www.proesite.com, as of June 27, 2005. The new 64-bit workstation
also established a world record on EnSight 8.0 benchmark that is used to
gauge the performance of identically named engineering visualization
application-based on results published at
http://www.ensight.com/products/performance.html as of July 27, 2005.
Sun's Ultra 20 Workstation has easily surpassed the competing
Intel-based systems from other hardware vendors.

"Adding the AMD Opteron 100 Series processors with ECC unbuffered memory
support to our x64 (x86, 64-bit) workstation product line gives our
customers even more break-through performance at lower costs than other
competitive x64 workstations currently on the market," said Lisa Sieker,
vice president of marketing, Network Systems Group at Sun. "Recent
record-breaking benchmark results for the Ultra 20 Workstation are a
testament to the power and performance we continually see on our x64
systems that are powered with AMD processors."

ECC unbuffered memory support will also extend to the Dual-Core AMD
Opteron 100 Series processors, expected to be available within the next
30 days. Additionally, AMD plans to support ECC unbuffered memory on
future AMD Opteron 100 Series processors designed for DDR2 and other
emerging memory technologies.
With a simple BIOS update, AMD Opteron 100 Series supporting
g ECC unbuffered memory will use the existing AMD 939-pin package.
Infrastructure partners including Supermicro Computer, Inc. and Tyan
Computer Corporation already support this package and are the first to
offer motherboards enabling true server solutions based on the new AMD
Opteron 100 Series processors. Processors in the AMD Opteron 200 and 800
Series will continue to utilize Socket 940 which is validated for the
registered memory configuration required by these processors.

"The AMD Opteron 100 Series processors with ECC unbuffered memory
support, coupled with our Tomcat K8E (S2865) motherboard, enables Tyan
to uniquely address the needs of our 1P server and workstation customers
who are looking for high-performance at an improved price point," said
Danny Hsu, vice-president of Sales and Marketing at Tyan Computer
Corporation. "The power and performance inherent in this exciting new
addition to the AMD64 family will provide our customers with the
capability to realize higher gains without higher cost overhead."

"In April, we expanded our product offerings with AMD64 technology-based
solutions," said Tau Leng, director of marketing, Supermicro Computer,
Inc. "With the new AMD Opteron 100 Series, we are able to offer our
customers even more compelling 1P server and workstation solutions
within an infrastructure that best suits their needs."

Pricing and Availability
The new AMD Opteron 100 Series processors with ECC unbuffered memory
support offer a compelling price/performance ratio, beginning with Model
144, priced at $125 in 1,000-unit quantities, and scaling to Model 152,
priced at $799 in 1,000-unit quantities. Dual-Core AMD Opteron 100
Series processors with ECC unbuffered memory
support, ranging from Model 165 at $417 to Model 175 at $530 for
1,000-unit quantities, are expected to be available within 30 days.

About the AMD Opteron(tm) Processor
More than 75 percent of the top 100 of the Forbes Global 2000 companies,
representing the world's most competitive industries, now use AMD
Opteron(tm) processor-based systems to run applications at new levels of
performance. The AMD Opteron processor, based on AMD64 technology with
Direct Connect Architecture, made history as the industry's first x86
multi-core processor for servers and workstations that is both 32- and
64-bit capable. Dual-Core AMD Opteron processors can deliver higher
performance within the same power envelope as single-core processors
because they were designed from the ground up for multi-core computing.
With a broad portfolio of dual-core and single-core solutions and a
robust 64-bit ecosystem, AMD and its customers are leading the way to
the next evolution of enterprise computing.
