We also note the peak power recorded in any of our tests. These tests are done as comparative models. These include full workflows, real-world image-model construction, and others as appropriate. However, for our tests in this review, we measure the power consumption of the processor in a variety of different scenarios. Obfuscation like this is a frustrating endeavor for press and end-users alike. Intel kind of screwed this up with the Tiger Lake launch in September 2020, by refusing to define a TDP rating for its new processors, instead going for a range. All turbo modes and power modes above that are not covered by warranty. In simple terms, processor manufacturers only ever guarantee two values which are tied together - when all cores are running at base frequency, the processor should be running at or below the TDP rating. Reaching for Turbo: Aligning Perception with AMD’s Frequency Metrics.Talking TDP, Turbo and Overclocking: An Interview with Intel Fellow Guy Therien.Why Intel Processors Draw More Power Than Expected: TDP and Turbo Explained.These topics are 10000-12000 word articles in their own right, and we’ve got a few articles worth reading on the topic. The difference comes to turbo modes, turbo limits, turbo budgets, and how the processors manage that power balance. Turbo can sometimes be very aggressive, allowing power values 2.5x above the rated TDP.ĪMD and Intel have different definitions for TDP, but are broadly speaking applied the same. Exactly how far the processor goes depends on a few factors, such as the Turbo Power Limit (PL2), whether the peak frequency is hard coded, the thermals, and the power delivery. This allows, usually for a limited time, a processor to go beyond its rated frequency. Modern high performance processors implement a feature called Turbo. For the processors we test at AnandTech, either desktop, notebook, or enterprise, this is not always the case. For many markets, such as embedded processors, that value of TDP still signifies the peak power consumption. Historically the peak power consumption of a processor, as purchased, is given by its Thermal Design Power (TDP, or PL1). The nature of reporting processor power consumption has become, in part, a dystopian nightmare.
