RAPL provides a way to set short term and longer term averaging windows for power limits. Because multiple bursts of heavy workloads will eventually cause the ambient temperature to rise, reducing the rate of heat transfer, one uniform power limit canвЂ™t be enforced. By dynamically monitoring the feedback of power consumption, power limits can be reassigned based on use and workloads. In addition, power limits in a rack enable power budgeting across the rack distribution. This will allow a monitoring and control program to dynamically limit max average power, to match its expected power and cooling budget. RAPL provides a way to set power limits on processor packages and DRAM. Based on our measurements, they match actual power measurements.

This software power model estimates energy usage by using hardware performance counters and I/O models. RAPL is not an analog power meter, but rather uses a software power model. RAPL provides a set of counters providing energy and power consumption information. RAPL Use Cases RAPL Power meter capability This interface is called the RAPL interface.

In addition, it exported these power meters and power limits used in its calculations through a set of MSRs (Machine Specific Registers) and PCIe config space. Sandy Bridge added onboard power meter capability, which can be used to make better decisions, rather than decisions based purely on models. Before Sandy Bridge microarchitecture, turbo decisions are driven by models, which by nature tend to be conservative, to avoid issues in some isolated cases.

The PCU uses some internal models and counters to predict the actual and estimated power consumption. Once the GPU is added to the package, its power must also be considered in making this turbo boost decision. A Power Control Unit (PCU) firmware decides based on the: IntelВ® Turbo boost technology allows processor cores to run faster than their base frequency, if the operating condition permits. This is achieved by introduction of turbo mode. So, out of two, if one core is more active than the other, it can use the remaining thermal budget and run at a higher frequency. To avoid this, the CPU will use different maximum frequencies, depending on the number of active cores. If the CPU is using maximum frequency on both cores, this will consume more power than TDP.

If one more core is added, a multi-threaded workload can demand full performance on both cores. With a single core CPU, an application demanding performance will get full performance, as long as it is under TDP. LetвЂ™s analyze how a TDP can influence performance. Using basic physics, heat will take some time to propagate, so a short burst may not necessarily violate TDP. It is possible for the processor to consume more than the TDP power for a short period of time without it being вЂњthermally significantвЂќ. But this is not the same as the maximum power the processor can consume. This is the power budget under which the system needs to operate. For example, for a processor with TDP of 35W, Intel guarantees the OEM that if it implements a chassis and cooling system capable of dissipating that much heat, the chip will operate as intended. The thermal design power (TDP) represents the maximum amount of power the cooling system in a computer is required to dissipate.
