AMD’s Ryzen 9 5900HX laptop CPU has leaked and will be part of the next-generation Cezanne-H family of processors based on the Zen 3 core architecture. Ryzen 9 5900HX spotted by TUM_APISAK Inside the Geekbench database and features faster performance than 8-core desktop-grade processors.
AMD Ryzen 9 5900HX Flagship Zen 3 Notebook CPU Destroys Intel Core i7-10700K and last generation Ryzen 7 3800X CPUs in single and multi-threaded benchmarks
The AMD Ryzen 9 5900HX CPU will be the main offering within AMD’s Cezanne-H chipset. The processor will have all-new Zen 3 cores which we’ve seen on the Ryzen 5000 desktop lineup and as such, we can expect some huge performance gains in the single-threaded processor.
In terms of specifications, the AMD Ryzen 9 5900HX will offer 8 cores and 16 threads. The chip will have 16MB of L3 cache and 4MB of L2 cache. The chip’s base clock is rated at 3.30GHz and the boost clock is rated at 4.70GHz. Detailed benchmarking log shows that all cores were clocked at 4.70GHz during testing. Other features of the chip include an improved Vega GPU and also overclocking support, which will be a first for AMD in the laptop segment.

The test platform was the ASUS ROG Zephyrus Duo 15 SE (GX551QS) laptop, an advanced design aimed at enthusiasts. ASUS will also offer the same laptop with Intel Tiger Lake-H CPU flavors. The laptop features 32GB of DDR4-3200MHz memory, and while this is a high-end design, it’s likely to power the NVIDIA GeForce RTX 30 series graphics card for the notebook that launches at CES 2021. In fact, all the major tech vendors including AMD, NVIDIA, and Intel will showcase their new high-performance laptops at CES 2021.

In terms of performance, the AMD Ryzen 9 5900HX CPU scored 1534 points in the single-core and 9,015 points in the multi-core tests. The standard AMD Ryzen 7 5800H which is also an 8-core Cezanne-H chip based on the Zen 3 architecture leaked a few days ago and this chip scored 1,475 points in the single-core and 7,630 points in the multi-core tests. This makes the Ryzen 9 5900HX 4% faster in single tests and 18% faster in multi-core tests, which is a huge increase but is expected to power the chip much higher. Compared to its flagship Ryzen 7 4800H predecessor, the Ryzen 9 5900HX is 41% faster in single core and 36% faster in multi-core tests, which is a massive increase in just one generation for the laptop segment.
But that’s not all, we also compared the chip to Intel Core i7-10700K and AMD Ryzen 7 3800X desktop processors. In multi-core tests, the Ryzen 9 5900HX ends up faster, even by a small margin, than desktop parts configured to run at much higher TDPs while the Ryzen 9 5900HX should ship with a 45W TDP. In single-core tests, the Ryzen 9 5900HX only destroyed the Zen 2 based Ryzen 7 3800X with a 19% lead while the Core i7-10700K ends up 14% slower.
We’ve seen Ryzen 9 5900H and Ryzen 9 5900HX processors leak earlier as well, and while Intel has Tiger Lake-H around the same time as the Cezanne-H, it looks like the blue team will have a very hot battle in the high-performance portion of this year’s notebook. It also looks like the major OEMs will be shipping AMD Ryzen 5000 laptops with top-of-the-line NVIDIA RTX GPUs which will take away more of the appeal that Intel has had in the high-end gaming laptop segment for a while now.
