The Dell G15 5520 is more budget-friendly and offers a good balance for general use and gaming, with reasonable portability and battery life. It's particularly suitable if you prefer a device with longer battery life and don't require the highest end performance. On the other hand, the Razer Blade 18 is more expensive but provides top-notch performance suitable for the most intensive tasks, including 3D rendering and machine learning, with a larger and high-quality display. While it excels in performance and display, it is less portable and has shorter battery life compared to the Dell. Consider the Dell if price and battery are priorities, and the Razer if performance and screen quality are your main concerns. Give Feedback

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."

"Razer made a powerful laptop in the Blade 18, showing off a beautiful and fast display and the same high-quality build we’ve come to expect from this product line. It’s also quite expensive, which is hardly a surprise, but bears repeating even in this price range. It’s pricier than the Scar 18 despite an inferior GPU and half the storage, so you really have to want the Blade 18’s design to justify the cost."
