Toms Hardware published AMD vs. Intel and 2 almost identical laptops in direct comparison: Which processor wins? A quote from the article:

Should you rather choose an Intel processor or an AMD CPU for your laptop at the same price and comparable platform? This is THE question of all questions, which has been asked again and again for years and yet has been so difficult to answer until now because direct comparison has almost always been lacking. The still existing cooperation with Tom’s Hardware (FR) and Tom’s Guide now enables us to answer exactly this question in practice. And so my thanks go first of all to the colleagues from France, who kindly provided me with the data. This, by the way, is not a one-way street, but in the end it is a completely different story.
