My guess is:

You didn't read enough.

There are a lot of articles, tutorials and build guides in this site. It's best to read them first, especially those with a system similar to yours.

This is by far too little information.

Why don't you write a build guide yourself? Put there as much information as possible and your benchmarks. Then it's much easier to help you and I am guite sure your questions will be answered.

Great! And please describe more of your system, every detail of hardware and software used. The more information available, the quicker somebody can help with your problem.

Comparisons show that the RX 590 should have much better performance than the 5500M.

Thunderbolt bandwidth is less than bandwidth of direct PCIe connection. More importantly, Thunderbolt adds some latency compared to direct PCIe connection. The latency means that the difference in performance between direct PCIe connection and Thunderbolt connection can be lessened by using higher resolution and quality settings (which will reduce fps).
