Well, not exactly plenty, since GDDR based GPUs, if we exclude GDDR6 like i mentioned, according to TPU database, for 32bit we had only cut down Nvidia G72 (GDDR3) which i think is wrong reporting, it's just plain DDR3 , for 96bit only cut down Nvidia GP107 (GDDR5) which for all i know it could be 128bit with mixed memories capacities and Nvidia drivers reporting whatever (although official specs suggest 96bit bus) check the GURU3D review, is it 3 memory chips, or 4 memory chips with the one upside down? i couldn't tell, probably 3)
Nvidia recently released a new entry-level SKU into the market, a GeForce GTX 1050 with 3GB graphics memory. In this review, we'll confirm if this product really is a GeForce GTX 1050 Ti, with less m...

and finally for 160bit only cut down Nvidia GP106 (GDDR5) but again it could just be 192bit with mixed capacities (I couldn't find any 5GB PCB photo) Of course my impression could be wrong since Nvidia chips is like a black box and maybe since pascal generation they had a way to disable one memory 32bit channel somehow, but in any case, we are talking for only 2 Nvidia models for all the GDDR era , so not exactly plenty....
