The next-generation AMD Opteron server processor, which is based on the Bulldozer architecture, will display the user set the maximum TDP (Thermal Design Power), which will enable clients to manage the power consumption of the CPU in accordance withtheir specific needs.
Opteron currently rely on lethal P-state to obtain a similar result, but this approach limits the maximum operating frequency of the CPUand can have a detrimental effect on chip performance.
"With the Cap Managers Power AMD these days, you can limit theprocessor P-state and cut power consumption even though this limits the ability of processors to get the upper frequency (which is also where the most power-hungry on the curve as you canimagine ...). "
"By essentially" locked "state of P, the processor never enteredinto the country, even under heavy use, help reduce the total powerto the processor," said John Fruehe, Director of Product Marketingfor Server, Embedded and products at AMD FireStream, inposting on the company's official blog.
In order to overcome the performance loss associated withdisabling P-state, next-generation AMD Opteron processorsbased on new Bulldozer architecture will use TDP Cap Power,according to Fruehe.
Unlike previous iterations of technology, this new version will allow customers to determine the boundaries of the TDP in a gradualWatt power means that instead of having to choose betweendifferent power ratings draw for the processor, which can really get a CPU for the TDP is required.
More importantly, when running the workload does not exceed thelimits of new power modulated, the chip can still operate at top speed because there is no CPU P-states are locked.
According Freuhe, this new technology will be included in both theValencia and Interlagos core, which is expected to become officialin the third quarter of 2011.
