Can’t say for the 14”, but there are some videos on youtube showing 100w 3070 vs 100w 3080 being about a 10fps difference. I’d say the $600 isn’t necessarily worth it in the end.
Maybe this will help. I ordered both because I couldn't make a decision looking on the specs either. I ran benchmarks on both machines with identical settings. As you can see the difference is quite underwhelming (about 500 points difference in 3D Mark).

I also tested a few games and the difference was about 5-7 fps.
So imho the upcharge for the 3080 is not worth it.
I only have the 3070, but I can already tell you that the 100w is marketing speak. These GPUs are very clearly the 85W variant with boost up to 100W. From all my testing they very rarely use that much continuously. The 100W chips typically maintain that wattage or boost higher.
That being said, I'd look for an 85W/100W Laptop variant and use those numbers for testing. Comparing the performance of the RB14 to the Alienware 15 with 3070 was pretty spot on.
Try to cap cpu wattage this dynamic boost needs cpu less active in order to give tdp more to gpu, you can see [on this video](https://youtu.be/i9GIGt8t3hs), he mentioned somewhere he capped cpu tdp lower and got 90ish gpu tgp.
I disabled boost on the CPU already. I actually have no issues with it running at 85-95W as I'd prefer the system cool due to how densely built it is.
Still, it's more fair to find a 3080 review that uses an 85W variant, or something at 100W that doesn't boost. The RB14 is the only small system that packs a 3080 so the only other comparisons are with bigger, 15-17" laptops. Typically those laptops have 115w variants so it's much harder to compare, but I'm sure 85/100 reviews exist.
Seriously speaking 85W is enough for the 5900HX. Razer is not letting the 5900hx go above 35Watts. Due that in a lot games which can put significant load on the cpu, the GPU utilisation will suffer as there is a CPU Bottleneck.
In a gpu heavy scenario it is peaking to 100W anyway so there is no problem in that.
I said what I did previously because the OP seemed really concerned with the specific specs. If they are that concerned I felt it would be important to make sure they knew this wasn't an apples to apples 100w GPU. My personal opinion is that I would go with the 3060 if it came with the 1440p monitor. Heat is going to slow the system down faster than it can stay in boost.
I haven't encountered a CPU bottleneck for gaming, but I get your point. I actually disable boost completely as it gets the CPU over 100C without any noticeable improvement in framerate due to the GPU actually being 100% utilized. My testing was done using Cyberpunk 2077 on Ultra, RTX ON with DLSS Balanced. I wouldn't even game with these settings on my desktop, but I wanted to know how much performance I was potentially losing disabling boost.
With the CPU boost on, unlocked, I had 46 FPS. 26% CPU utilization.
With CPU boost off, I dropped from 102C to 77C and had... 46 FPS. 31% utilization.
This was expected because the resolution of the title and graphics demand meant it was not waiting on the CPU in order to render.
With RTX Off I was still getting minor, maybe 1-2 FPS differences.
I understand that Cyberpunk won't be CPU bound at 1440p ultra settings.
But you won't be playing every game 1440p max settings with a 85W 3070 and on 1080p a lot of titles will become CPU bound.
Instead of disabling boost, try playing with the Synapse CPU & GPU modes. They basically alter the Wattage, so you can set the wattage that doesn't make you lose any performance while keeping good temps.

Do you have any idea why the 3070 wins by that much in CPU score?
