If you prize a high-quality display and powerful performance for tasks like 3D rendering, the ASUS ZenBook Pro Duo 15 stands out with its OLED screen and superior processing power. Its dual-screen feature could be especially useful for multitasking and productivity but expect a higher price and lower battery life. Alternatively, the Dell G15 5520 presents a more budget-friendly option with a respectable performance suited for gaming and general engineering use, plus a higher refresh rate for smoother visuals. However, its IPS display won't match the color accuracy and contrast of the ASUS's OLED. Both laptops are similar in weight and not particularly light, but the ASUS, with its premium features, tends to be less portable due to its shorter battery life. Give Feedback

"Benchmarks aside, the Asus ZenBook Pro Duo is hard to compare with other PCs. Its closest competition may be a multi-monitor desktop, or a laptop with an attached travel monitor. The Pro Duo is more portable and versatile than either of those options, especially with the software tools Asus has thrown on top. For a certain niche of artists, media creators, and gamers, all that might add up to something special, even if it’s unattainable for the rest of us."

"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."
