The performance envelope was already uninspiring. They said it does better than some big percentage of the people on Steam, but it's not an obvious upgrade over my 2023 Legion Go handheld in anything but a bit more RAM (and it's only 8GB discrete VRAM, which may be paltry for 4K).

4k is only expected to be 1080p + DLSS, it's really good enough for that class of HW
