If you want something built well, portable, got some guts and has a reasonable warranty/support story - consider the Lenovo Thinkpad X13 AMD. It maxes out to 32Gb DDR4 with a Ryzen 7 4750U. It's got a 13.3" screen and weighs 1.3kg.
Personally speaking, I was in the market for a portable machine with 32gb memory (was not initially considering AMD). I considered the Dell XPS 13" (32gb variant was insanely expensive in Aus at $5.2k just for the unit), the X1 Carbon (maxes out at 16gb of ddr3), and the T14 AMD (a bit too chunky). When none of these were viable I considered the Macbook 13 (a bit more $, but a horrid keyboard despite beautiful screen), and the System76 Lemur (strongly considered it, but the support story in Australia was a bit of a risk for my daily driver).
When Lenovo had a sale on the X13 AMD, let's just say I could buy it + 4yr warranty + a dock for less than half the cost of the Dell/Apple, and have twice the cores.
Compromises were: a fairly pedestrian screen vs other Lenovo models or Apple/Dell, no thunderbolt, and needing to pull the trigger on it when there were literally zero reviews of this device on the internet. Jury is still out on the battery life too.
Great performance, sturdy, sleek design, great air circulation. 144hz refresh rate screen.
I'm using its predecessor Y540, intel based, GTX 1660 Ti. Great for gaming and work. The only downside is the speaker's not that good. Never been this satisfied with a laptop with this price range.
