ASUS Expertbook vs Zenbook (Which One is Better?)

Expertbook and Zenbook are two popular models of Asus laptops that cater to consumers who are looking for ultra-portable yet powerful laptops with long battery life.

Both ExpertBook and ZenBook are light weight and feature packed enough to challenge the top players in the market today. Although they look alike, a close scrutiny would reveal that they differ from each other in many ways.

Let us take a closer look at these two contenders for the ultraportable laptop.

Who is ZenBook for?

  • Office workers who need a lightweight laptop with good performance for daily office use.
  • Those who play online games that need decent graphics (but not extreme graphics).
  • Anyone who needs high performance but able to manage with 16GB RAM and 1TB storage.
  • Creative users such as architects and designers.

Who is ExpertBook for?

  • People who are always on the move for office or business purposes will find this super lightweight laptop a great choice.
  • Those who are looking for extended battery life. This will take you a whole day on normal use.
  • Travel bloggers and Youtubers who want to edit and publish things on location.
  • Professionals such as architects and lecturers.

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
IntegratedGDDR5GDDR5,GDDR6

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.

However, MX450 has been developed in the Turing architecture compared to the previous generation Pascal architecture of MX350.

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.
