Graphics comparison

ExpertBook and Zenbook come with a choice out of 3 popular graphic cards. Here’s a brief outline of their technical details.

Iris XeMX350MX450
Shared MemoryDedicatedDedicated
400 – 1350 MHz1395 – 1575 MHz1531 – 1594 MHz
10 nm14 nm12 nm

Iris Xe is faster as it’s on-board but the Nvidia cards have more memory and operate on separate power. With far less power consumption, Iris Xe graphics is the best choice for battery life.

Having said that, in real life experience Iris graphics would perform any task that requires decent graphics. Many games would run perfectly well on Iris Xe graphics at a low to mid frame rate although the Nvidia card would perform better.

Keyboard: The spill resistant keyboard is a good addition for office and business use, especially for those who travel extensively. Zenbook doesn’t offer the feature but you have two options of key travel to suit your typing habit. This is a plus for those who regularly use the laptop for creating documents.

Ports: Both laptops have similar ports with the only difference being the zenbook’s use of previous version USB which won’t make a huge difference in office use. Zenbook’s old school SD card reader would be a great option for DSLR camera users.
