Telstra has revealed the addition of almost one million new mobile services in the six months to December 2011, but Sensis revenues plummeted 24 percent in 12 months.
Chipmaker AMD has released its new quad-core Opteron server processor, claiming a significant performance edge over Intel. According to AMD, Under the newest SPECcpu2006 benchmarks, AMD dual-core Opteron processors beat Intel Xeon equivalent by up to 15%. However, the jury is still out as to how the new quad-core Opteron stacks up against Intel's quad-core server offerings.
According to AMD, its benchmark testing of the
new quad-core platform shows a 50% increase in integer and
floating-point performance compared to its dual-core Opteron
counterpart. There is plenty of education going on at the AMD site
attempting to demonstrate the importance of correct benchmarking and
the difference in scalability between the quad-core Opteron with its
direct connect level 2 cache and the Intel Xeon with its shared level 2
cache.
Notably, however, there is no definitive statement or set of benchmarks
comparing the respective quad-core offerings of the two companies,
which is rather surprising given that AMD goes to great pains to
explain that meaningful benchmarking involves comparing "apples to
apples".
The new quad-core server platform will begin shipping this month, while
the desktop AMD Phenom quad-core chips are expected to be on the market
by December.
AMD has enlisted the support of OEM heavyweights including IBM, HP, Sun
and Dell, among others to help rally the troops to its cause, which is
to claw back the hard won market share it has lost to Intel in the past
year, while waiting to bring its quad-core range to market.
“Sun is thrilled about the introduction of Quad-Core AMD Opteron
processors. Incorporating Sun’s innovative design principles that
enable stunning scalability and industry-leading performance-per-watt,
our upcoming Quad-Core AMD Opteron processor-based servers and
workstations will only accelerate the momentum Sun is experiencing in
its x64 business,” said John Fowler, executive vice president of Sun
Microsystems’ Systems Group. “With so much pent-up demand for the
scalability of native quad-core processing, Sun believes there will be
rapid, widespread adoption of Quad-Core AMD Opteron processor-based
systems. We applaud AMD for yet another technological breakthrough, and
are excited to continue to grow our alliance.”
Aside from performance issues, hardware OEMs are no doubt pleased that
there is now competition in the quad-core space as it will put downward
pressure on prices. Pricing info can be found here .
