What is Thermal Design Power:
Well, those for are familiar with computer processors and it features, for them the most important feature is Thermal Design Power or TDP in short .
Processor manufacturers use the term “TDP” in their own means.Hence, some concept of it remains unclear. Here, in this blog, I shall try to clear and cover all the related concepts about it.
TDP is an abbreviation of Thermal Design Power or Thermal Design Point or Thermal Design Point. Thankfully, all of these mean the same. In general terms, it means the amount of heat that is produced under severe workload. The amount of heat increases with the increase in processing.
TDP is very much useful when selecting cooler for CPU. Because for coolers, Thermal Design Power is the amount of heat, that must be released from the CPU surface. As TDP refers to heat, hence, its unit is ‘watts’.
TDP with respect to processor:
For an example, TDP of Intel core i7 9750H is 45 watts. Here 45 watts of Thermal Design Power mean the components associated with cooling the CPU, should in-take minimum heat of 45Watts. Generally, it refers to the power consumption under maximum theoretical load. Therefore, different manufacturers define their limits.
Intel tags its TDP requirement by keeping processor at base frequency rather than boost. So, even in low work load Intel processor gets hotter than its tagged in the spec sheet.
Whereas , AMD(Advance Micro Device) uses more realistic cases for measuring Thermal Design Power. AMD runs mid to high load software for tagging TDP for its processor. Hence, stock cooler that comes with AMD package with enough for cooling need.
Other Thermal measures:
Tcase Max Temperature: It’s the temperature recorded by the sensor near integrated heat spreader.
TJunction Max Temperature:
It’s the temperature that the processor will allow working smoothly. In the event when this temperature exceeds, the processor’s internal thermal control mechanism will kick-in. Therefore, reducing the frequency to prevent overheating.
In this blog, we learned about TDP and how it affects processing power of a computer. We hope, this blog will help you in future to select appropriate processor when you buy your next computer.
