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.

Using it since it was lunched 2017. it was good CPU then, still good, never felt the need to upgrade even with the new super fast 13980hx. Using it with 64GB in MSI gt83 and no complains. I even sometimes underclock to save power.
