GPD Win Max 2 is a 10,1" laptop and gaming handheld in ome. The 2023 refresh is powered by either Ryzen 7 7840U (or Ryzen 5 7640U) equipped with Radeon 780M/760M integrated graphics respectively.
The device comes with up to 64GB of LPDDR5x RAM (while Asus, Lenovo, and others tend to cut it at 16GB or offer 32GB with some absurd top spec bundle) working at up to 7500MT/s speeds which is the maximum supported by the SoC. Additionally, two M.2 PCIe 4.0 SSDs are supported - one standard size 2280 and one short 2230.
I have some benchmarks, reviews, and accessories covered on my website: https://rkblog.dev/posts/pc-hardware/gpd-win-max2/
Aside from the laptop itself, I'm also testing eGPU over USB4/Thunderbolt 3 and OCuLink which is present on the device (pure PCIe 4.0 x4 external connector).
