x86 Quad-Core Processor for Datacenters
Mon, 10/29/2007 - 6:00am
AMD introduced the Quad-Core AMD Opteron. Designed from inception for datacenters, Quad-core processors with the company’s Direct Connect Architecture introduce innovations that go beyond four x86 processing cores on a single die of silicon. Believed to be the first native x86 quad-core microprocessor, they offer desirable energy efficiency with a 50 percent increase in integer and floating-point performance, enhanced virtualization 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. The processors are bolstered by a variety of new power-saving technologies such as the company’s CoolCore Technology which turns off off unused parts of the processor; Independent Dynamic Core Technology, an enhancement to AMD PowerNow technology that allows each core to vary its clock frequency depending on the specific performance requirement of the applications it is supporting; and Dual Dynamic Power Management (DDPM), which provides an independent power supply to the cores and to the memory controller, allowing the cores and memory controllers to operate on different voltages, determined by usage. DDPM is available in most Quad-Core AMD Opteron processor-based platforms in this recent introduction.
