Recently bought an X1 Carbon with a 1270P CPU and had to return it. In hindsight, the P processor was probably a bad idea, but I assumed if they had it as an option then it would be capable of cooling it. Unfortunately, that was not the case. It was very fast if you only used it for a few minutes from cold, but even just light office use would cause the laptop to warm up until it started to hit thermal throttling, even at only 10%-20% CPU use. Under heavy loads it was even worse, performance dropping to about 20% after 10 mins - equivalent to a desktop CPU from the early 2010s. Sure you don't buy an X1 for building kernels, but you do expect it to be able to handle Zoom screen sharing. Ultimately, I found that it performed worse under normal usage than the 5 year old X1 Carbon it was intended to replace.
