Specifications
The first comparison with that stands out when compared to its bigger brother, the Zotac GeForce GTX 1050 Ti OC, is that the core is clocked at a slower speed, base of 1303 MHz and a boost clock of 1417 MHz.
It may not mean a lot to many PC builders, but the Mini is 3cm shorter than the OC. For my upcoming build in a Cooler Master Elite 110 mini-ITX case, that extra 3cm of room meant whether I could fit in some components or not.
