AMD Ryzen 9 5980HS: Zen 3 Enters Mobile Arena

The Core Architecture: From Zen 2 to Zen 3

A major leap from the previous generation, the Ryzen Mobile 5000 series transitions from Zen 2 to the more advanced Zen 3 architecture. This shift brings enhanced IPC (Instructions Per Clock) and a redesigned core layout, moving from a dual 4-core CCX to a single 8-core CCX. The result is improved performance and reduced latency, maintaining an eight-core design but in a more efficient configuration.

Upgraded Cache and Sustained Frequencies

AMD has also doubled the L3 cache in the Ryzen 9 5980HS, now boasting 16MB of unified cache, addressing a critical need for more cache memory. The processor also sees a frequency bump, with a base clock of 3.0 GHz and a boost clock reaching 4.8 GHz, promising better performance in various workloads.

GPU and Other Component Updates

While the Zen 3 cores take center stage, other components see less dramatic changes. The GPU remains based on the Vega architecture, albeit with a higher clock speed. The memory controller and other features like PCIe and display engines remain similar to the previous generation, all built on TSMC's 7nm process.

Ryzen 5000 H-Series Lineup

AMD offers a diverse range of chips in the Ryzen 5000 H-series, including standard "H" and overclockable "HX" models at a 45W default TDP, and the power-optimized "HS" variants at a lower 35W TDP. The Ryzen 9 5980HS leads the HS series with its 8-core, 16-thread configuration and elevated Vega compute unit clock speeds.

Asus ROG Flow X13: A Compact Powerhouse

The Asus ROG Flow X13 serves as the testbed for the Ryzen 9 5980HS. Astonishingly compact, this laptop houses the powerful Ryzen chip, a GeForce GTX 1650 Max-Q GPU, and 32GB of LPDDR4X memory, all in a chassis no larger than a typical 13-inch ultraportable. Its 13.4-inch 4K display emphasizes the laptop's small footprint, and at just 2.8 pounds and 15.8mm thick, it's a marvel of engineering.

Testing the Ryzen 9 5980HS

In our benchmarks, the Ryzen 9 5980HS was tested in two power configurations: the standard 35W and an overclocked 45W mode. This was to assess the processor's performance in different scenarios and compare it with competitors' CPUs under similar conditions. The Asus ROG Flow X13, despite its compact size, doesn't compromise on performance, especially with its H-series CPU.

Benchmarking and Performance Expectations

The Ryzen 9 5980HS's performance was evaluated against various laptops to provide a comprehensive picture of its capabilities. The benchmarks focused on different aspects of computing, from general productivity to more demanding tasks, to gauge the processor's strengths and limitations.

Conclusion: Ryzen 9 5980HS in the Mobile Market

AMD's Ryzen 9 5980HS is a testament to the company's progress in the mobile CPU market. With its advanced Zen 3 cores, increased cache, and efficient design, it sets a new standard for high-performance mobile processors. The Asus ROG Flow X13 exemplifies how this power can be harnessed in an ultra-portable form factor, making it a compelling choice for users seeking top-tier performance in a compact package.
