In multi-core loads, the Ryzen 9 5900HX easily steals the crown from last gen's king Ryzen 9 4900HS. However, the more impressive feat is recorded with the single-core tests that are usually dominated by Intel processors. Here, the 5900HX manages to reach the top position by defeating the workstation-grade Intel Xeon W-10885M.

The first test results for AMD’s upcoming high-end Ryzen 9 5900HX mobile APU are here, and the chip puts to shame any other mobile processors previously released by both Intel and AMD. The new HX processors feature the 7 nm  Zen 3 cores, which, for the first time on a mobile Ryzen APU, are unlocked and can be overclocked beyond the default 45 W TDP.

PassMark reports that the new AMD APU was tested on an Asus laptop along with 32 GB of RAM and an RTX 3080 GPU. With its 3.3 GHz base clocks and 4.6 GHz boost frequencies, the Ryzen 9 5900HX managed to score 24,039 points in multi-thread loads, beating the Ryzen 9 4900HS by around 16%. It is important to note that 7 out of the top 10 mobile processors in the multi-thread tests provided by PassMark are from AMD. Now, the single-core charts are clearly dominated by Intel's chips, but the Ryzen 9 5900HX still manages to beat each and every one of them, with a 10% advantage versus the second place Intel Xeon W-10885M workstation-grade processor. Presumably these results were achieved without overclocking the APU, so there would still be room for more performance gains.

We can only imagine the scores that can be achieved with the top-of-the-line Ryzen 9 5980HX with 100 MHz faster boost clocks. There will also be a Ryzen 9 5900HS with locked cores, and rumor has it that AMD could also launch a 5900H model.

I first stepped into the wondrous IT&C world when I was around seven years old. I was instantly fascinated by computerized graphics, whether they were from games or 3D applications like 3D Max. I'm also an avid reader of science fiction, an astrophysics aficionado, and a crypto geek. I started writing PC-related articles for Softpedia and a few blogs back in 2006. I joined the Notebookcheck team in the summer of 2017 and am currently a senior tech writer mostly covering processor, GPU, and laptop news.
