The Dell G15 5520 is a more affordable option and offers good performance for general use, gaming, and some engineering tasks. It also has a decent battery life but is a bit heavier and larger than some alternatives. On the other hand, the Razer Blade 17 is more expensive but comes with a more powerful processor, better graphics, and more RAM, ideal for intensive gaming, 3D rendering, and machine learning tasks. It has a larger, higher-resolution display which is great for creative work but results in a slightly lower battery life and less portability due to its size and weight. Choose the Dell if you need a cost-effective, well-rounded machine, or the Razer if top-notch performance and a premium build are priorities despite the higher cost and reduced portability.

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."

"Our test configuration of the Blade 17 targets gamers and creative professionals. A Core i9-12900H processor, GeForce RTX 3080 Ti Laptop GPU (175 watts TGP after the BIOS update, 16 GB of VRAM), and 32 GB of working memory equip the laptop for video processing, rending, and 4k gaming at the highest level. In addition, a fast PCIe-4 SSD (1 TB) ensures short load and storage times. With the Blade 17 (Early 2022), Razer delivers a successful and powerful work device for creative professionals. But this also has its price."
