I can hit some of those FPS numbers with a $850 4070 laptop without frame gen. Not every setting needs to be ultra (looking at you shadows). When you're already hitting 144fps what does another 5% matter?

Well yes, both 5090 mobile and 5080 mobile use the same GB203 die.
112 ROPs vs. 96 ROPs respectively, or 16% more ROPs in the 5090 mobile.

But Ultra settings at any resolution is the HIGHEST load a GPU can get in that scenario. They're not testing using optimized settings, they're testing for the heaviest settings.

I don't see why there's so little difference in performance, when there's such a large difference in hardware. Could they have optimized for the hardware that most people have (not the most expensive) to optimize the reviews.

Note: Remaining specs are the same, except for the price.

For starters, the mobile 5080 and 5090 are the same GB203-400 die, and the same VRAM width and speed. If the laptop design then caps the power budget equally for both variants, the main difference is price, prestige and a few more weights for you LLM.

I guess that's the CMOS "knee" curve for you: at the low end of the 90-150 Watt range you may well be below the optimum of the fully enabled chip so it can't really spread its wings. That's also the reason they'd never put a GB202 die into a (real) laptop, because at 90 Watts you may not even be able to light all those transistors up. And if they were to run, it would be well below the kneecap optimum.

There have been lots of cases in the past where a supposedly cut-down chip still effectively delivered the same performance, because thermal budget and VRAM bandwidth were the actual limitations.

At around 50-90 Watts 4060m and 4070m also deliver very near the same performace, even if they are different chips yet share the same VRAM specs, a very different story on the desktop ...at 100% different power budgets.

Every laptop is different. There are so many variations. Just because one gets worse performance than a previous gen doesn't mean it's bad. It's just how the laptop is spec'ed overall.
Just wait for more to come and find the best deal for what fits you, the consumer.
The 5080 at as high wattage as possible will do well. Obviously, if it were limited to 100 watts or something close it won't do as well but the capabilities are still there.
Most people buy laptops for other than just gaming.
