ASUS ExpertBook P5 G1 Adds a 16-inch Option, but the Real Upgrade Is Serviceability

ASUS announced the ExpertBook P5 G1 on March 31, 2026 with new 14-inch and 16-inch versions, up to Core Ultra 7 255H, and support for up to 96GB RAM plus dual SSDs up to 6TB. The key story is not the AI label. It is that this thin business line still allows meaningful memory and storage upgrades.

What Changed

ASUS introduced the ExpertBook P5 G1 in two sizes (14-inch and 16-inch) for business users. The company lists up to Intel Core Ultra 7 255H, up to 96GB DDR5 memory, and dual PCIe 4.0 SSD support up to 6TB total.

A concrete CPU comparison inside this lineup is clear: Core Ultra 7 255H vs Core Ultra 5 225H. According to official processor specifications, that is 16 cores vs 14 cores, 24MB vs 18MB cache, and up to 5.1GHz vs 4.9GHz boost.

Compared with many thin business laptops that keep RAM and storage more restricted, this model keeps two SO-DIMM slots and a dual-SSD layout, which can matter more in long ownership cycles than a small AI feature list.

Why It Matters

The practical buyer impact is upgrade flexibility. Teams that buy one chassis and scale specs later can start lower and expand RAM/storage instead of replacing the full laptop sooner.

This matters most for IT-managed office fleets, analysts with large local datasets, and users who keep devices for 3 to 5 years. It matters less for buyers who replace laptops every year or always use fixed high-spec configurations.

One limit is still important: ASUS has not published launch pricing or a clear regional ship schedule yet, so the value argument is incomplete until channel pricing appears.

Practical Takeaway

Watch this model if you want a business laptop with modern H-series performance and real upgrade headroom in memory and storage. If final pricing lands close to mainstream premium business notebooks, it could be a smarter long-cycle buy than thinner models with less serviceability.
