Memory: 32 GB

What reviewers say

Reviewers praise the two excellent OLED screens, the new hinge that brings them closer together, very long battery life and, in the Core Ultra X9 model all three tested, strong integrated graphics. All three found it expensive; KitGuru found it chunky and a little heavy with its ports crowded together, and Digital Trends notes integrated graphics still limit heavy creative work.
