There are only a handful of AMD options worth mentioning and availability for models is very regional. Those without a dGPU are the Lenovo S540-13ARE (4800U but has dual-fan/dual-heatpipe cooling and runs at a sustained 38W), these TongFang PF4/PF5 models (a variety of OEMs like the Slimbook, Tuxedo), the 2020 Redmibooks, and the just announced Honor Magicbook Pro.
The rest are mostly gaming models. The Asus G14, TongFang's GK5/GK7 (like the Eluktronics RP-15/17), HP Omen 15, and the Lenovo Legion 5 are the best of the bunch. They all have Nvidia 1660Tis/2060s.
The 4800H performs on par with the 10875H at lower temps/power usage but I think competition w/ a Macbook is going to be subjective. None have anywhere close to the fit and finish of a MBP. Most are significantly cheaper. Most will have a better port selection and better upgradability (although some also have soldered RAM). Most will have better battery life. Only a few will be more portable. Only a few support USB-C PD. Only a few have >FHD screens and if you need >100% sRGB color gamut, there's literally only one AMD option (the 4K Schenker VIA 15 Pro), and that won't be available until September at the earliest. There are plenty of 10875H+ laptop options on the Intel side. Some like the new XPS's are specifically designed to compete head-to-head w/ MBPs.
For a while it was only the ROG Zephyrus. I think there have been others in Linus or Dave2Ds videos. A bunch were due to come up earlier this year but it all got pushed back.
e.g. 4xxxH like this laptop
Most laptopts I see use the 15W versions, very rare to find anything competitive with Macbook.
