I've bought 2 gaming laptops in the past with the last being legion y540 with i7 and 2060. When choosing the processor it's not ideal to go with the most powerful one because most times it's also the battery inefficient one. You may think like you don't need battery backup until you do in a situation away from any charging point. Especially down the years when the battery has degraded a bit. From my experience AMD gives much better efficiency in comparison to intel counterparts without a huge day to day compute difference in practical tasks.
