Dell Alienware X17 R2 vs MSI Prestige 15

"The Alienware x17 R2 recognizes targets a significantly higher TGP of 175 W for a roughly 30 percent performance boost over laptops running on the ~100 W GeForce RTX 3080 Ti like the Razer Blade 15 or Gigabyte Aero YE5. Similar results can be found through the CPU as well. This single aspect of the Alienware is perhaps the biggest differentiating factor between it and other ultrathin gaming laptops. Of course, the "performance at all cost" approach comes with drawbacks. Power consumption in particular is through the roof and battery life suffers because of it even when on the lowest performance settings."

"The MSI Prestige 15 offers a dazzling 4K image quality, and solid performance. The MSI Prestige 15 appears to consistently implement the guiding principle of throttling the solid and efficient hardware to such an extent that content creation succeeds perfectly. Performance-hungry tasks, on the other hand, are slowed down a little by the reduced power consumption. Conversely, this means that the case remains relatively cool and the dual fan subdued. The battery life also benefits somewhat. So the losses aren't really dramatic because full performance is still available for short bursts."
