Significant difference in WiFi speeds in two laptops kept aside

I have two gaming laptops, one is Dell G5587 and other is MSI GF75. Both have the same WiFi cards (Intel(R) Wireless-AC 9560 160MHz) and both have the same WiFi drivers. The WiFi speeds are similar near to the router but at some distance there is a significant difference in their speeds.

Dell G5587 - Around 60 Mbps (pretty much similar closer to router) 

MSI GF75 - Around 5-6 Mbps 

I am using the 2.4Ghz network band. What could be the reason for such difference in speeds although they have the same card and drivers?

It is possible that one is connected to a different channel on the router. Even if both are using the same frequency.

poor antenna design? 

We can't Benchmark like we used to, but we have our ways. One trick is to shove more GPUs in your computer. Like the time I needed to NV-Link, because I needed a higher HeavenBench score, so I did an SLI, which is what they called NV-Link back in the day. So, I decided to put two GPUs in my computer, which was the style at the time. Now, to add another GPU to your computer, costs a new PSU. Now in those days PSUs said OCZ on them, "Gimme 750W OCZs for an SLI" you'd say. Now where were we? Oh yeah, the important thing was that I had two GPUs in my rig, which was the style at the time! They didn't have RGB PSUs at the time, because of the war. The only thing you could get was those big green ones.

No I checked it by myself. Both are using the 2.4 GHz band

2.4GHz is the frequency. There are 11 channels on the 2.4GHz radio band in North America. A router should try to chose channels with the lest amount of interference, one laptop could be on one with more interference.

Your router settings might give that information, depending on the model.

Maybe not very good internal antenna?

The card could be same but antenna design is up to each individual manufacturers
