How the Apple MacBook Air 15 (2023) and the Dell Alienware X17 R2 compare to other laptops
"The Apple MacBook Air 15 is boringly good. The new MacBook Air 15 is a very good, but also boring device, because apart from the larger screen and the higher price, there are no differences compared to the smaller MacBook Air M2 from last year. No new processor, no additional ports, just the usual basic hardware - but the overall package is extremely good and it simply works. Above all, the lack of fans is an aspect that should not be underestimated in everyday use. In our opinion, the Air could be a lot better, but Apple goes easy on itself here."
"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."
