Apple Silicon competitor: Qualcomm's 8cx Gen 4 based on Nuvia design

I had a Lenovo X1 Carbon (Gen 7? The first model with the 4K display option) and it was smaller and lighter than a MBA with a larger screen. Seriously, it weighted NOTHING.
It also got hot enough to fry an egg on, and gave me about 30 minutes of battery life from fully charged.

I have a Lenovo X11E (first gen), and its no where near thin and light. Battery life is very good as is the heat management. I viewed this as the minivan of laptops, not sexy but does what you ask of it.
Thinkpads generally were good, I can't say if that is the case now, but when I bought mine years ago they were.

We'll see when it's out, I do hope it's a solid product and that it kickstarts ARM as an actual option for Windows/Linux users.
FPS/Watt is a new one on me. Even so, would you be willing to accept a GPU that is 40% slower than the GPU on the M2? That is not even comparing it to the M2 Pro or Max.

The M-series processors are already very good. M2 is a significant advancement on M1, and M1 was fast and very efficient at scales above that of a phone processor. To beat that, a Nuvia-created core would need to take the state of the art as it was when those employees left Apple (which was a few years before the M1 was released) and play catch up.
If you look here

you will see the rumoured details of the 8cx gen4 are quite similar to a M2 Pro, with up to 8 performance and up to 4 efficiency cores, and with each block of four cores having 12MB of shared L2 cache and 8MB of L3 cache, plus 12MB of system-level cache and 4MB for graphics.
I would be surprised if they can deliver on the original promises of significantly better than M1 performance-per-watt.

I'd be surprised if they could deliver superior performance, never mind per watt
They were projecting greater than M1 performance in 2020. I believe it.
It should be a good match against M3 in performance per watt.

Yes but then they would say that, its just marketing talk untill we see an actual product. The first few benchmarks will be interesting but I am skeptical.
we also have to see what is the outcome of the ARM lawsuits over the license they granted Nuvia, which was non-transferable in the event of a take-over. I believe ARM wanted Qualcomm to destroy all Nuvia designs from prior to the take-over and start again under the terms of Qualcomm’s ARM license.
