Alienware m15 2019 review: the importance of the processor cTDP

ByLydia Scott 2019-05-29 267

In our test of the Alienware m15, we realized that its CPU performance outperformed other equivalent configuration machines. The effectiveness of the cooling system is of course a parameter to take into account, but there is more than that: the cTDP (configurable TDP) and the Power Level applied to the processor are not to be neglected.
                   

A configurable TDP story

Specifically, if Intel sets a TDP of 45 W for its Core i7-8750H, the manufacturer of the notebook can apply several levels of maximum power not to exceed, depending on the efficiency of the cooling system. In the case of the Alienware m15, the cTDP is set at 35 W as recommended by Intel, but these are two other values ​​that are interesting to watch: PL1 and PL2.

The PL2 is the maximum achievable for a short time and it varies according to the notebook model: 90 W on the m15, it also reaches this value on the Asus TUF FX505GM, while the Razer Blade is limited to only 80 W Note that peaks beyond this limit are allowed for only a few milliseconds.

The limit PL1 is lower, but the processor can theoretically remain indefinitely at this level of consumption, the limit PL1 being normally defined according to the cooling capacities of the notebook. On the Alienware m15, this limit is set at 60 W, just like on the Razer Blade 15, while the Asus TUF FX505GM is for example limited to 45 W only. In practice, there is a moment on all these models where under a sustained load, the processor falls back to its 35 W cTDP.

It is therefore better understood the differences in behavior and performance of the same processor according to the notebook model: the higher the allowed consumption, the higher the frequency will be, as long as the temperature remains below the throttling limit!
