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."

"We like a lot about this laptop. It has many ports, with the inclusion of RJ45-Ethernet as a defining feature. WWAN is upgradable for maximum flexibility and the ThinkPad has many security functions. Working with the ThinkPad input devices is a lot of fun, and Lenovo puts in a serviceable Low Power panel. The AMD Ryzen 7 Pro 7840U delivers a great performance and does not drain the battery fast. Fan noise and temperatures are nothing special, but also far away from bad. With the user replaceable keyboard, the ThinkPad T14 Gen 4 has a special feature rarely present on most modern laptops."
