A decent CPU, however, stuck inside the smaller chassis of the Alienware 15 R3 (2017) it continually thermal throttles. This makes the main positive aspect of this chip, being unlocked, pretty much useless as the temperatures will rise too much for overclocking to be useful. Even without overclocking this chip runs very hot. Only recommended for 17 inch sized laptops.  [Dec '19 ThreeAreLeft]
