Intel Self Tuning Processor: CPU readjusts itself to cooling and workload
Intel is currently experimenting with an extended version of the Turbo Mode. The integrated control mechanism adjusts the CPU parameters to the given situation. Even temperature and voltage peaks are taken into account
With the current Nehalem architecture Intel has introduced the Turbo Mode. This technology automatically increases the frequency of individual processor cores if an application does not make use all of them. Of course the rise does not exceed the specified TDP limit.
Now the chip maker takes another step and tests a self tuning processor which automatically adjusts itself to given conditions like cooling, ambient temperature and workload. Current CPUs have a certain safety margin for the operational voltage and clock speed in order to compensate voltage drops or extreme workloads. This might become obsolete with the new technology.
On the experimental chips Intel uses several controlling mechanisms to adjust the CPU automatically to the given situation. Thus it is possible to increase the performance, stability and energy efficiency. The controllers for example recognize if the voltage is not sufficient for the applied frequency and automatically adjust the parameter before the system becomes unstable. It is also imaginable that those sensors recognize the temperatures and increase the frequencies if the cooling capabilities are sufficient - more or less a new Turbo Mode.
