memory interface issues

[smmushfiqur256]

A gtx 1060 has a 192bit memory interface
and a Rx 160 has a 128bit memory interface
So my question is that most of the gpus have 128 or 256 bit memory interface.
WIll 192bit cause bottleneck or other certain issueS?

To work this out you will need to know the Memory speed aswell (Mhz).
Referring to your worry, 192bit interface will not cause a bottleneck though no.
