Upload speed 3 times faster on iPad

I have AT&T Fiber 1 Gbps and for some odd reason my Windows 10 PC, which is less than 2 or 3 years old, gets about 50 to 100 Mbps upload speed with google drive. When I upload the same exact file from my iPad to google drive I get around 200 to 300 Mbps. No I can not see the speed on my iPad but it says uploading complete in 2 to 3 minutes compared to 10 to 12 minutes on my Windows 10 PC.

My question is why is this ? The other weird part is my Windows 10 PC is connected to a Ethernet cable.

Of course the iPad is connected wireless.

This is the weirdest issue I ever had and still not sure what is up with it.
