I'm considering buying the Razer Core X but nowhere can I find out if it is compatible with my laptop. Can someone help me?

And as far as I know it only needs a Thunderbolt3 connection as compatibility
For it to work you only need Thunderbolt 3 and you have it.
But what do you want with it? Your laptop has an RTX2070. You won't achieve much more performance with an eGPU. Or do you want to get another PCIe device to run?
Nope, mine has a GTX 1650
