Recent tests by Neal Nelson, an independent computer performance expert, show that while some Quad-Core Intel Xeon based servers delivered up to 14 percent higher throughput, similarly configured Quad-Core AMD Opteron based servers consumed up to 41 percent less power. The test servers used 1 gigabyte memory modules at 4, 8 and 16 gigabyte main memory sizes.
CHICAGO (Business Wire EON) January 14, 2008 --
Recent tests by Neal Nelson, an independent computer performance expert,
show that while some Quad-Core Intel Xeon based servers delivered up to
14 percent higher throughput, similarly configured Quad-Core AMD Opteron
based servers consumed up to 41 percent less power. The test servers
used 1 gigabyte memory modules at 4, 8 and 16 gigabyte main memory sizes.
“By themselves the Intel (NASDAQ: INTC)
processor chips may use less power, but all current Intel Xeon servers
require the use of Fully Buffered memory modules. These FB-memory
modules appear to consume more power than the DDR-II memory modules used
by the AMD (NYSE: AMD) based servers. The result is that in many cases
an Opteron based server actually uses less total power than a Xeon based
server,” observed Neal Nelson, designer of the
test.
These new test results were collected with Neal Nelson’s
Power Efficiency Benchmark which is a client server test where up to 500
world wide web users from 32 separate computers submit individual
transactions to a server running the Apache2 web server software, the
MySQL relational database and Novell’s SUSE
Linux Enterprise Server operating system. The benchmark has a complex
multi-user load with a large memory footprint, a high volume of context
switches, significant network traffic and substantial amounts of
physical disk I/O.
“I am certain that these test results are
correct,” Nelson continued, “I
am so certain that I have begun to offer my customers a money back
guarantee if their real world experiences do not agree with my benchmark
data.”
The Nelson test results should not be confused with power usage test
results from the Standard Performance Evaluation Corporation (SPEC). The
SPECPower test has a single client machine feeding batches of 1,000
transactions to a small number of Java based application programs.. The
SPECPower test has a small memory footprint, a low volume of context
switches, simple network traffic and it performs no physical disk I/O.
The SPEC test was created by a committee of computer vendor employees
and SPEC offers no guarantee that their numbers will correlate to a
customer’s real world experiences.
The Nelson test was designed and executed entirely by the independent
computer consulting firm of Neal Nelson & Associates. The quad core
tests referenced above were not financed or sponsored by any outside
company or group.
Nelson's firm has over 35 years experience providing data processing
consulting services to some of the world's largest computer customers
including the U.S. Army, U.S. Navy, the Internal Revenue Service,
McDonalds, WalMart and Federal Express. Nelson’s
benchmarking laboratory is available to commercial and government users
for independent computer performance tests.
