First one is a Stock Model
Core Clock
1050 MHz
Boost Clock
1178 MHz

Second is a Superclocked
Core Clock
1140 MHz
Boost Clock
1279 MHz
Due to Uncertainty i suggest buying a Stock model and Overclock it yourself

If the Superclocked Model starts crashing on you the only way to fix it is Underclock it to STOCK...Get my drift
