"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."
"Passionate gamers who want to play demanding modern titles with maximum details and don't mind spending the moolah will find the Lenovo Legion 7 Pro to be the right choice. The bright, sharp, and color-accurate 16:10 QHD 240 Hz display makes for an immersive viewing experience. The hardware is housed in a stylish chassis that feels premium and scores well in terms of workmanship and stability. Other aspects such as sound quality, input devices, and connectivity also seem to be near-perfect."
