HP Envy x360 is great. It has a 6 (real) core AMD Ryzen 5 4500U, nice screen and absurd battery life (12 hours or something ridiculously long like that). https://rwmj.wordpress.com/2020/07/18/amd-zen-2-laptop/ The single thing I don't like about it is they've overloaded the backslash/pipe key on to another key.

I don't want to buy an expensive laptop with only 16G RAM.

Why not? The only thing that really eats ram is chrome tabs

I function in a data analysis role and the only place I typically get to crunch number is my own laptop.

Running a Docker container for SQL Server and doing some work with pandas will eat up my 16gb pretty easily.

I know that was trolling :) But let me answer you:

32GB+ RAM on laptop lets me run complete micro-services production-like environment (Java, VM, Docker) locally with efficient development/debug capabilities.

And that is at any place where I can get electricity and LTE/4G/3G which is enough to git pull/push or check on-line docs few times a day.

Unintentional trolling I guess. I'm just ignorant of what people use the RAM for, and reluctant to accept that our apps need this much.

HP Elitebook 845/855 AMD support 32GB RAM officially, but they have 2 SODIMM slots so theoretically should support 64GB. One thing to watch out with Linux on HP laptops with AMD currently are problems with standby mode. They lack S3 deep sleep power state - only provide S2Idle so called Modern Standby. Although there are ways to mod ACPI tables there is still some black screen issue when the return from suspend happens - search stories on Reddit. I hope constantly improved Linux kernel will bring some workarounds and HP will do more Linux testing too on their quite decent HW specs.

I finally decided to go with proven option and ordered Lenovo T14 with 48GB RAM. It works flawlessly with Linux 5.8 because Lenovo added "legacy" S3 power state mode toggle in BIOS setup specially for non-Windows OSes.

48G means single channel RAM, which slows down the GPU a lot.

With Ryzen 4000, it means the first 32GB are running in dual channel and the remaining 16 are single channel.
