All of these "test" speed connections send small data packets data back and forth at a certain speed. When you get into the real world, you have different packet sizes. You are also at the mercy of the target site speeds and internet busyness. So what you get at a real site might not be close to what these speed testers produce.

For example, I can do Windows update and get great download speeds one day and terrible speeds the next day. It is probably different servers and busyness.

Also direct connect vs WiFi. I have two PCs in the same room - one direct connect and one WiFi. The rates are definitely different.

Bring up Task Manager and go to the Networking tab and watch a download. Do the same on a WiFi connection and you will not only see a different download rate but you will see a different link speed.
