New AMD Processors Cut Server Energy Costs

Here the good news for those which want to make green their centers of data processing: The new generation of the processors of quadruple-core of AMD Changha� include the single devices of energy saving which can reduce the energy costs, while increasing power of waiter.

AMD presented its processor of Opteron of the Quadruple-Core 45nm (which was �Changha��) called last November. Since then, that functioned to cut the consumption of energy, and announced yesterday two new processors of Changha�, the AMD Opteron IT, conceived mainly for energy efficiency, and it of AMD Opteron, conceived for the centers of data processing which require as much computing power like possible.

With the core of energy saving is a new device called the AMD PowerCap. In its blog, the director of John Fruehe of the development of the businesses for products of waiter/work station with AMD, known as PowerCap:

he will make it possible directors of datacenter to fix preset limits maximum for the frequency and the tension of the clock of the processor, allowing a flexible solution at the energy costs of maintenance. Since many workloads tend to being out of ear in kind, the need for running at the frequency of the highest clock is often only for one cycle or two. The assistances of capsuling power to smooth the peaks outside and can help to maintain a better power average total. In fact, the director of AMD PowerCap can reduce the power of processor of waiter of up to 63%. And our technology of AMD CoolCore, which lets to you stop the unutilised parts of the processor, is now prolonged to include the L3 hiding-place.

It is potentially a certain very significant saving of power. Posterior complaints of Fruehe in its blog that Changha� which IT delivers until an improvement of 44% of execution to the power compared with the former generation of Changha� processors.

The HP, Dell, and Sun already announced waiters based on the new processors.
