Intel's attempt to activate AMD may have failed. Intel recently suggested in a presentation that it could be very concerned about the performance of AMD CPUs on certain laptops. Notable differences in performance are highlighted in Intel's slides when both AMD and Intel laptops run on batteries and are not attached to the wall. While Intel claims victory, the results and methodology are in doubt.

Despite recent advances like the Iris Xe graphics, the presentation suggests that the AMD CPUs could offer better battery life in laptops when compared to Intel, but at the expense of CPU performance. In particular, Intel claims that AMD's CPUs reduce their performance by around 40% to 50% compared to their own, which means only 8% when powered only by a battery.
The bottom line is that when benchmarking without AC power, the Intel chipsets perform better. Intel also claims that AMD's CPUs take 7 to 10 seconds to switch to turbo mode, which results in poor battery performance. Intel-owned systems are able to do this much faster, depending on how most people use their laptops.
However, as ExtremeTech argues, Intel's methodology in all of these tests is flawed and the conclusions are heavily biased. Averaging the results ignores cases where the AMD CPU is ahead in benchmark results and gives a very broad indication that battery results are the be-all and end-all of laptop performance metrics. Nor is there any mention of the fact that manufacturers set many of the parameters for laptop power consumption and performance, specifically choosing to test Lenovo AMD laptops while looking at a much wider range of Intel systems.
Again, Intel could purposely skew these results to make AMD look bad and restart the debate between AMD and Intel. Its own portfolio is also much larger than AMD's because the chips are contained in more laptops. While Intel holds its own in onboard GPU gaming, AMD leads the way in many key areas of the mobile space. Given that Intel has only dominated Intel on the desktop with its Ryzen 5000 CPUs, it seems Intel is more concerned that it might do the same on laptops.
