ZenBook 13 in review: Is it better to go with Ryzen or with Intel Core? There are good arguments for both.

Should you buy the ZenBook 13 with an AMD or an Intel CPU?
Should you buy the ZenBook 13 with an AMD or an Intel CPU?
The new ZenBook 13 is finally available in an AMD Ryzen configuration. We have now completed the review of the Intel version and are able to draw a comparative conclusion. While AMD pulls ahead in terms of pure CPU power, the Intel ZenBook still has a few aces up its sleeve.

We have just finished our review of the Asus ZenBook 13 with the Intel Core i7-1165G7. Since we recently reviewed the same ZenBook 13 with the AMD Ryzen 7 5800U, it's time for a verdict and a clear purchase decision - but unfortunately, there's no entirely clear choice.

Both ZenBook 13 variants are good subnotebooks. If you're expecting the only difference to be found in the processor, you're mistaken. Several other aspects depend on the SoC, such as heat development, noise, the internal graphics unit, and also the connectivity capabilities.

If we look at the pure CPU performance, however, things look bad for Intel. In our Cinebench R15 measurement, the Ryzen was almost twice as fast in the multithread test! The lead is clear, which is no wonder, since Intel only offers 4 cores, while AMD offers 8.

However, the situation is a bit different when it comes to the integrated graphics unit, as the Intel G7 GPU has slight advantages here. Therefore, users who occasionally want to play computer games on the ZenBook might favor Intel here.

Another advantage of Intel, and quite a big one, is the integration of Thunderbolt. The Intel version integrates two Thunderbolt 4 ports, while AMD processors don't support Thunderbolt at all. At the same time, the interface is becoming increasingly more popular and important; certain devices, such as an external graphics card case can't be connected to the AMD ZenBook in this way - a big minus point, despite the still not definitively resolved security concerns regarding the Thunderbolt interface.

On the other hand, the low noise levels speaks for AMD; the Intel ZenBook gets louder under load, but it stays cooler and is more energy-efficient due to the lower performance.

Consequently, it always depends on the user's requirements. And we shouldn't forget: This is a small subnotebook at 13 inches. Whether the raw CPU performance (AMD) is more important than interface compatibility (Intel), low noise levels (AMD), or energy efficiency (Intel) is up to each individual user to decide.

A C64 marked my entry into the world of PCs. I spent my student internship in the repair department of a computer shop and at the end of the day I was allowed to assemble my own 486 PC from “workshop remnants”. As a result of this, I later studied computer science at the Humboldt University in Berlin, with psychology also being added to my studies. After my first job as a research assistant at the university, I went to London for a year and worked for Sega in computer game translation quality assurance. This included working on games such as Sonic & All-Stars Racing Transformed and Company of Heroes. I have been writing for Notebookcheck since 2017.

I've been fascinated with technology ever since I got my very first Android smartphone, which was quite a while ago. The power packed into such a small footprint still amazes me. Learning to program made my understanding of technology deeper, and at the same time, it expanded my interest to the area of desktop computers and laptops. All this led me to enjoy reading and watching reviews of new devices, and that's how I stumbled upon Notebookcheck. I immediately found their reviews to be very comprehensive, and luckily, I've even had the chance of translating them since 2019. When it comes to the huge field of technology, I'm currently also interested in specializing in Java programming.
