As the second generation model in the series, we expect the Alienware m15 R2 to be objectively better than the first generation Alienware m15 R1 in every way. This isn't necessarily the case even on paper; both RAM and WLAN are now soldered while battery capacity is smaller this time around. In turn, users gain 2.5 Gbit Ethernet, improved keyboard feedback, optional Wi-Fi 6, per-key RGB lighting, and an arguably more attractive look that doesn't feel any weaker or stronger than the outgoing design it replaces.

Dig deeper into the m15 R2 and its disadvantages begin to show. CPU temperature in particular is too high for comfort at nearly 100 C when gaming even with the fans set to maximum. We would have been okay with the high temperatures had they meant quieter fans or faster performance than the competition, but that is not the case. If alternatives like the Asus Zephyrus S GX531, HP Omen 15, Razer Blade 15, or MSI GS65 can each run 20 C cooler, then there's no reason why the Alienware m15 R2 shouldn't be able to as well. We unfortunately observed these same results on the older Alienware m15 R1 to suggest that the m15 R2 chassis doesn't solve one of our main criticisms about the relatively new Alienware m15 series.

Perhaps as a result of the high CPU temperatures, the Core i7-9750H in the m15 R2 performs slightly slower than the average i7-9750H in our database and even the Core i7-8750H in the Alienware m15 R1. CPU Clock rates can be much more variable than anticipated and frame rates when gaming are consequently a bit lower as well when the CPU is heavily stressed.

If you're in the market for an Alienware laptop, there's no shame in opting for the older Alienware m15 R1 as the m15 R2 is more of a sideways step in terms of overall performance, upgradeability, and features. We recommend investing in a high refresh rate display while avoiding the Core i9 and base 8 GB RAM configurations.
