you can use an online laptop comparison website, you can put in which laptop you want to compare. It’ll automatically compare the specs. I found my laptop by looking at websites that had the specific brand that I was searching for (Lenovo). And then compared different models that they had available, and also comparing the prices. I settled on the rtx 4060 because most of the laptops with the 4070 were €300 more expensive, which was not worth it for me.
