AMD today introduced the Quad-Core AMD Opteron processor, which it is touting as the world’s most advanced x86 processor ever designed and manufactured as well as the first native x86 quad-core microprocessor. 

Designed from inception for the most demanding datacenters, Quad-Core AMD Opteron processor-based servers from global OEMs and system builders can deliver breakthrough capabilities to customers in a time of dramatically escalating performance-per-watt emphasis.
Quad-Core AMD Opteron processors with AMD’s Direct Connect Architecture introduce innovations that go beyond four x86 processing cores on a single die of silicon.
Critical considerations for today’s most challenging business requirements inspired Quad-Core AMD Opteron processor innovations: energy efficiency with a 50% increase in integer and floating-point performance, enhanced virtualisation performance, and investment protection via a customer-centric approach enabling non-disruptive transitions from dual- to quad-core within the same power and thermal envelopes to help keep infrastructure costs down.
“Today marks one of the great milestones in microprocessor achievement as AMD again raises expectations for industry-standard computing,” says Hector Ruiz, chairman and CEO of AMD. “We’ve worked closely with our customers and partners to design a new generation of processing solutions embodied by today’s  Quad-Core AMD Opteron processor – a four-way winner in performance, energy efficiency, virtualisation and investment protection. Early customer response has been extremely positive.”
Quad-Core AMD Opteron processor-based systems from global OEM and system-builder partners begin shipping this month and are expected to increase in number through the remainder of the year.
AMD Phenom processor solutions, which will leverage many of the same benefits of this innovative, next-generation architecture, are expected to be available for the desktop market in December.
Due in part to the industry’s most stable x86 server platform, more than 50 socket compatible Quad-Core AMD Opteron processor-ready system choices are on the market today from tier one OEMs, all of whom are publicly supporting today’s introduction.
They include HP, Sun Microsystems, IBM, Dell, Appro, Egenera, Gateway, Rackable Systems, Supermicro and Verari.
Additionally, AMD is providing the channel with an opportunity to offer their customers Quad-Core AMD Opteron processor-based solutions very soon after launch, with the AMD Validated Server Program platforms available today.
AMD has also introduced the Average CPU Power (ACP) metric, which represents processor power usage, including cores, integrated memory controller, and HyperTransport technology links, while running a suite of typical and relevant commercially useful high utilisation workloads to be more indicative of the power consumption that end-users can expect.
ACP is a useful metric for data center operators when estimating power budgets to size their datacenters. AMD will continue to provide thermal design power (TDP) specifications to platform designers in AMD power and thermal datasheets.
As datacentres face the potential of doubling their energy consumption by 2011, new Quad-Core AMD Opteron processors introduce energy-efficient x86 architecture, bolstered by a variety of new power-saving technologies.
These include AMD CoolCore Technology, Independent Dynamic Core Technology, and Dual Dynamic Power Management (DDPM)
In addition, Quad-Core AMD Opteron processors with Direct Connect Architecture excel in virtualised environments because of the integrated memory controller for reduced memory latency, and Rapid Virtualisation Indexing, a new AMD innovation in AMD Virtualisation technology designed to reduce the overhead associated with software virtualisation.
Rapid Virtualisation Indexing takes functionality that was previously performed in software and greatly accelerates it by performing those functions within the CPU to help enable near-real time application performance.
