How the Dell Alienware m18 R1 and the Dell G15 5520 compare to other laptops
"Dell's Alienware m18 delivers on its promises: This is a large, powerful gaming laptop with the premium flair and feel you expect from an expensive purchase. The drawbacks are really the price and battery life, which in context are reasonable. (We'd also like to see more ports on the laptop's sides.) This price tier exists for deep-pocketed enthusiasts, and if you’re considering anything in this range, the m18 isn’t an outlier. For the majority of shoppers, of course, all of these mighty 18-inch systems are likely too expensive."
Olivier Martin, Ryan Lim, and John Peroramas | April 2023
"The Dell G15 (2022) is a 15.6-inch budget gaming laptop, and is great for gaming. You can configure the laptop with powerful Intel 12th Gen. CPUs and various NVIDIA dedicated GPUs, all of which deliver a smooth gaming experience at 1080p. There's also a QHD 240Hz display option if you want better visuals, though you'll have to pair it with the top-end NVIDIA GeForce RTX 3070 Ti to get good frame rates. It doesn't get overly hot or loud under load, and there's no noticeable throttling on the CPU or GPU. Unfortunately, the 120Hz panel has a slow response time, causing noticeable ghosting, and it doesn't support variable refresh rate."
