Yes, IF the wifi card/chip can go faster AND there isn't enough CPU left over after other things that are running to do the data transfer over USB. USB uses more CPU than an internal wifi card.
However, you have plenty of CPU as your passmark score shows for both single core and multi-core scores:

So unless your anti-virus is thrashing the CPU/hard disk then that's not the reason.

Both your internal wifi card and your usb wifi adapter are limited by the wifi chip they use, which is a single stream chip capable of connecting at 433Mbps.

On 802.11ac expect a maximum throughput of around half of the connection or link speed.
So, 433Mbps / 2 = 216Mbps throughput. Which is what you get on the internal card. So nothing limiting that, except the type of wifi chip.
With the USB adapter, it's a nano adapter which means a very small antenna which will reduce the signal and therefore the reliability and throughput further. So you're doing great to get 209Mbps out of it!
If you want higher speeds you need to get a dual-stream wifi card/adapter capable of connecting at 866Mbps.

The Router im using should be more than ample its an Asus AC87u.

Both ends of the connection need to support the same speed in order for you to get it. Having a super fast router that can do 1300Mbps connection rates is no good if you connect a device to it that can only do 433Mbps.
