Multitasking slowed the reviewed base model
Albert Unbox reported slowdown while playing YouTube, recording the screen and downloading software together. He also demonstrated lag in Photoshop. His unit had 8GB RAM and 256GB storage, so this is not a measured result for the 16GB/512GB configuration.
