What Does TDP Stand For In Computers?


What Does TDP Stands For?

TDP(Thermal Design Power) refers to current thermal effect and other heat generated by CPU when it is working. TDP is to set a requirement for the heat dissipation system, which requires the heat dissipation system to disperse the heat emitted by the CPU.

In other words, TDP is the total heat that the cooling system must be able to dissipate. It is mainly provided to computer system manufacturers, heatsink/fan manufacturers, and case manufacturers for system design purposes. The cooling system must ensure that the processor temperature remains within the design range when the TDP is at its maximum.

Therefore, the actual power consumption of the CPU will generally be less than the TDP, especially for CPUs that support overclocking. The TDP only represents the heat released at full load frequency.

How To Check TDP

TDP power consumption is usually officially announced and is also indicated on the CPU box. 

If you want to check out it yourself, you can use CPU-Z, a CPU detection tool. It supports CPU detection on 64-bit systems. Aside from using Intel or AMD's own detection software, it's the one we use the most. Cpu-z supports a wide range of CPU types, software startup speed and detection speed are very fast. 

How To Change TDP In Bios

It is advised to access the BIOS to check whether similar options exist. There is not much BIOS content in the branded machine, and without similar functionality, TDP limits cannot be changed in general.

The TDP power consumption of the processor is limited by the BIOS and processor power supply. So if you want to unlock, first of all, you need to modify the version of the BIOS, and then the machine also affects the performance of the processor. For example, the processor power supply of the machine can not meet the power supply of 15W TDP. If it is unlocked and used for a long time, the hardware life will be reduced. If there is no modification of BIOS, it can not be unlocked.

Is Lower TDP Better

A lower TDP power consumption is better. Low TDP power consumption means a lower CPU heat and easier heat dissipation. Different manufacturers may have different definitions of TDP, and Intel and AMD do not mean exactly the same for TDP power consumption. Because the CURRENT CPU has energy saving technology, the actual heat is obviously affected by the energy saving technology, the more effective the energy saving technology, the actual heat is smaller. At present, the TDP of the CPU of the general desktop computer is about 60~100W, and the CPU of the notebook computer is ranging from 5W to dozens of Watts.
