From the article you linked:
> With the new Panther Lake mobile processors, Intel has managed to successfully combine the two previous generations, Arrow Lake and Lunar Lake, as the performance is even better than with Arrow Lake, while efficiency has been improved at the same time. Even with low power limits, the performance is very competitive, and Intel (in conjunction with the new GPUs) is therefore the better choice for slim laptops.
Notice how it doesn't say it's more efficient than Lunar Lake.
Their benchmarks say LNL is more efficient.
