Efficiency issues with twelfth generation Intel processors?

Alder Lake-based twelfth generation processors, which Intel wanted to re-release in the processor market, were also assertive in terms of efficiency. However, mobile processors are allegedly unable to deliver the desired battery efficiency.

How efficient are the twelfth generation Intel processors?

We have seen that with the Alder Lake processors, Intel went to the separation of performance and efficiency cores. In particular, it contributes to battery savings by taking efficiency cores in low loads and background management.

At least On paper, this is so because the MobileMark 2018 tests of Lenovo laptop models show the opposite. The results of the same models with eleventh-generation and twelfth-generation Intel processors are disappointing.

For example, the Lenovo ThinkPad X13 G2 takes 14.5 hours, while the ThinkPad X13 G3 with Intel Core i5-1240P processor can reach 11.8 hours. The ThinkPad X1 Nano G1 reaches 13.6 hours, while the ThinkPad X1 Nano G2 stays for 11 hours. The ThinkPad X1 Carbon G9 reaches 16.7 hours, while the X1 Carbon G10 reaches 15 hours.

Of course, it can be thought that other components used in the new generation consume more energy, but these components also need to be efficiency-oriented. In short, the 10nm process on the Alder Lake side seems to have not fully achieved efficiency. Previously, it was discussed that Intel could achieve the expected efficiency performance with the 7nm process.
