Some thoughts about the new core ultra processor February 14, 2024 at 12:26 AM
The new ROG G16 2024, equipped with U7-155h, was tested and found to have nearly the same performance as its previous generation and the Flow X16. Additionally, there is almost no improvement in the battery life for the 2024 generation, even though the new processor is made using 7nm tech instead of the old 10nm. Therefore, I would definitely not recommend this CPU.

The i9 definitly has half the battery life. Dont know where that conclusion comes from considering the i9 lacks lpe cores.
