In a laptop, battery life and heat trump almost everything else. People with 4k screens tend to move from one plug socket to the next, but AMD has years of crappy corner cutting laptops (many still on the shelves of the stores) to overcome.
It's telling that they didn't release Bristol ridge laptops and desktops to review sites; if there was good news to shout about for the a 9000 series you can bet they would have done it. Instead, no launches, no information, nothing.
Its rare to find a review of the model laptop you want, with the chip in it you can afford(they almost always have the most expensive models). The few reviewers I have seen that compare models can at times remark that performance on even the same chips varies greatly due to the differing thermal and power limitations the system has, especially on the netbook style devices. And all of that is expected, because for most use cases the lowest end CPU's work perfectly for what most users want. Very very few people need a 62 watt I7 over a 15 watt core m/y variant or care if a image render is 3 seconds faster on one model over another. They use office applications, web based applications and watch videos/listen to music. And laptops from 8 years ago do that well, laptops with new chips excel at that.
