Lenovo ThinkPad P1 G4 Laptop Review: BIOS update provides more CPU performance

[Redaktion]

In our first review of the ThinkPad P1 G4, there were problems with the performance of the Tiger Lake CPU. However, we now observe a significant performance improvement with the latest BIOS version, and the CPU performance is now on par with that of the vapor chamber models.

Are you sure that the BIOS update is what solved the problem?  It sounds like you were using different hardware, and there are *many* reports of bad heatsink thermal pasting, so I would guess that you are seeing better performance because you have a build that happened to be done better.  Can you try downgrading the BIOS and doing the tests again to confirm whether it is the BIOS?  I tried 1.09 and 1.13, and didn't notice any difference.  With 1.14, the temperatures went *up* and the performance went *down* slightly, so I don't recommend 1.14.  On the other hand, I did tests before and after repasting the heat sink, and the performance was *much* better after repasting.
