Sebastian Bade | February 2021
"The Asus ROG Flow X13 is not an off-the-shelf convertible. This quickly becomes clear when you take a closer look at the technical specs. The AMD Ryzen 9 5980HS is a state-of-the-art SoC with 8 cores and 16 threads, which also makes the 2-in-1 interesting as a work device. With 32 GB of RAM and a 1 TB SSD, gamers are also well taken care of. The dedicated Nvidia GeForce GTX 1650 Max-Q fits well into the overall concept and ensures a solid 3D performance. With the eGPU dock, which is equipped with a GeForce RTX 3080, the small convertible transforms into a full-fledged desktop replacement in terms of performance."

"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."
