If you do not specify a type, Slurm will send your GPU job to a type designated "default" in the table above.
If you do not supply a type specifier, Slurm may send your job to a node equipped with any type of GPU. 
For certain workflows this may be undesirable.
For example, molecular dynamics code requires high double-precision performance, and therefore T4 GPUs are not appropriate.
In such a case, make sure you include a type specifier.
