Reviews for the Dynabook Portégé X40-M

90% I commuted with this laptop for a week, and its power, robustness, and connectivity didn't fail to impress
Source: Techradar English

At the end of the test, I was once again impressed with the processing and, to be honest, the GPU power afforded to the Dynabook Portégé X40-M by the Intel Core Ultra 5. It's able to handle Windows 11 Pro as well as any machine that I've tried, and when it came to Microsoft Office apps from Word to PowerPoint and Excel, this machine was highly optimised, producing one of the best benchmark results that I have seen for the Windows Experience, coming in at 8.3. Most media editing was also extremely well handled, and Photoshop and Lightroom ran surprisingly well, with both opening quickly and enabling quite advanced image edits as well as batched commands without too much of an issue. Having a dedicated GPU might have sped up the process, but if this is all you have to use, then you'll still be impressed by the performance.

Intel Graphics 4-Core: Integrated graphics card based on the Xe LPG architecture (similar to the dedicated Arc GPUs, but with a focus on efficiency). Provides 4 Xe cores (64 Xe vector engines) and 4 ray tracing units.

Modern games should be playable with these graphics cards at low settings and resolutions. Casual gamers may be happy with these cards.

Ultra 5 225U: High-end mobile processor based on the Meteor Lake architecture. Offers 2 performance cores with up to 4.8 GHz (incl. SMT) and 8+2 efficiency cores with up to 3.8 GHz and can therefore process 14 threads simultaneously. Similar to the Core Ultra 5 135U, however, the Compute-Tile is manufactured in the new Intel 3 process and offers higher clocked CPU cores.» Further information can be found in our Comparison of Mobile Processsors.
