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 stated that it is on track to ship its long awaited quad-core Barcelona processors in August promising "significant performance enhancements" over existing architectures. The AMD chips will be the first processors to implement four processing cores on a single die, unlike Intel's Clovertown Xeon processors which achieve four cores by bridging two dual-core processors together.
The new Barcelona processors, to be made using
65-nanometer manufacturing process, are promised to deliver a
performance increase up to 70% on database applications and up to 40%
on floating point applications at chip frequencies up to 2Ghz with
higher frequencies up to 3Ghz promised in Q407. The chips will also be
available in lower power versions.
According to AMD, there are significant advantages that four processing
cores on a single die will provide over Intel's existing quad-core
solution, which AMD has described as simply two dual-core processors
"stitched together". AMD and Intel have in the past waged a war of
words over whether the shared memory cache of Intel's implementation or
the discrete cache of AMD's quad-core chips is more efficient in terms
of performance and power consumption.
AMD claims that Intel's twin die quad-core solution is inherently
inefficient compared to AMD's single die solution because processing
cores on the new Barcelona chips each have their own discrete cache and
thus will not require additional clock cycles to flush and reload
memory when a request is made on a processing core.
“More than ever before, customers are expecting energy-efficiency and
performance-per-watt leadership as much as absolute performance. With
this new reality of computing, greater performance at the expense of
greater power consumption is no longer an option,” said Randy Allen,
corporate vice president, Server and Workstation Division at AMD. “AMD
has prioritized production of our low power and standard power products
because our customers and ecosystem demand it, and we firmly believe
that the introduction of our native Quad-Core AMD Opteron processor
will deliver on the promise of the highest levels of
performance-per-watt the industry has ever seen.”
AMD, which until last year had threatened to steal 30% marketshare from
Intel, has been hurting badly after Intel leapfrogged AMD's previous
technological superiority with a string of new releases in the past 12
months. Intel's smaller Silicon Valley neighbour is banking on its new
quad-core architecture to regain lost marketshare over the last
year.
