AMD's flagship Cezanne-H high-end mobility CPU, the Ryzen 9 5900HX, has been spotted within the Geekbench benchmark. A few days ago, the AMD Ryzen 7 5800H leaked out too by TUM_APISAK & now, the same leaker has spotted the fastest chip in the Cezanne-H family which is planned for an official unveiling at CES 2021.
AMD Ryzen 9 5900HX Flagship Cezanne-H 8 Core CPU Spotted, Zen 3 at 4.60 GHz For Mobility Platform & Overclocking Support
The AMD Ryzen 9 5900HX is based on the Zen 3 core architecture and as such, it should be part of the Cezanne-H lineup which is the direct replacement to the Renoir-H Ryzen 4000H CPUs and more specifically, the Ryzen 9 4900HS which utilized the Zen 2 core architecture. The AMD Ryzen 9 5900HX would be directly competing against Intel's Tiger Lake-H family of high-end processors which are launching in the first half of 2021.
Coming to the specifications, the AMD Ryzen 9 5900HX features 8 cores and 16 threads. The chip was running at a base clock of 3.30 GHz and a boost clock of 4.60 GHz. The CPU features 16 MB of L3 cache and 4 MB of L2 cache. The L3 cache is a major upgrade over the Ryzen 4000U and Ryzen 4000H 'Zen 2' processors, offering increase inter-core latency speeds and bandwidth. The CPU will come with AMD's enhanced Vega graphics core based on the 7nm process node.
The CPU should be a 45W design configurable down to 35W. The cores were running at an average clock of around 4.5 GHz which is close to the maximum single-core boost clock. The chip was tested on an ASUS ROG Zephyrus GX551QS laptop which is an upcoming design. We might get to see this variant announced at CES 2021 too.
The laptop features 48 GB of DDR4 memory clocked at 3200 MHz. There's no spec on the GPU but it is likely that Cezanne-H models will come equipped with NVIDIA's GeForce RTX 30 series mobility and AMD's own RDNA 2 based Navi mobility GPUs.
Coming to the performance numbers, in single-core, the AMD Ryzen 9 5900HX scores 1423 points while in multi-core, the CPU scores 6912 points. The AMD Ryzen 9 4900HS on average scores 1092 points in single-core and 7071 points in multi-core results. The single-core result is a massive 30% improvement over the predecessor while the multi-core score is on-par with the previous flagship. Compared to the Intel Core i7-10750H, the Ryzen 9 5900HX is 24% faster in single-core and holds a 25% lead in the multi-core tests.
