You can add few more points regarding the review which was published by Golden Pig Upgrade. Some performance comparison metrics and stuff like that.

First up, for all reviews AMD laptops were configured with 55W while the Intel laptops were configured at 65W. The Intel laptops were using LPDDR5-5200 memory while the AMD laptops were using LPDDR5x-6400 memory.

He also posted some synthetic and gaming benchmarks. In Cinebench R23 and 7-zip Intel had a lead in single-core benchmark but AMD ends up faster in multi-threaded benchmark.

In H.265, VCN 4.0 leads both VCN 3.0 and NVENC by 30% and 42%, respectively. In H.265, VCN 4.0 leads both VCN 3.0 and NVENC by 30% and 42%, respectively.

For gaming the reviewer took the NVIDIA GeForce RTX 4060 at the same TGP across all 4 laptops. The AMD Ryzen 7 7840HS delivered performance on par with Intel Core i7-13700H with LPDDR5-5600 memory, and the use of LPDDR5x-7500 ram could increase the performance substantially as noted in the video.

LPDDR5x-7500 actually delivered a 3.5% boost over LPDDR5x-6400 and a 16.57% boost over LPDDR5x-5500 memory, although I think there is still some room for improvement here, since these might be early Laptop samples. I couldn't actually understand the review properly.

Although the latest Ryzen CPU boasts superior GPU performance, the upgrade from the previous-gen RDNA2 iGPU is not substantial. Ultimately, the iGPU outperforms the GeForce MX550 discrete GPU and approaches the performance of the GeForce GTX 1650 Max-Q designs.

That's because the AMD's RDNA 3 core architecture used in Phoenix APUs is internally referred to as "RDNA 2.5" in AMD's documents, which means it is somewhat in between the RDNA 2 and RDNA 3 arch designs. Hence the performance uplift is less.
