We are examining the AMD Ryzen 9 5980HS Mobile APU inside the ASUS ROG Flow X13 laptop for use as a compute workstation and mobile gaming system. This system partners the AMD chip with 32GB of LPDDR4X-4266 memory and an Nvidia GTX 1650 Max-Q graphics card in 35W typical operation. As the graphics hardware is clearly underpowered by comparison to the CPU, we also test with ASUS' ROG XG Mobile RTX 3080 Laptop eGPU enclosure.

You may have seen our previous article highlighting some of the questionable operating behaviour of the ASUS system using default power profiles. AMD has since highlighted that the unexpected throttling behaviour is related to an ASUS Laptop MCU firmware update pushed out by Windows Update. We tried to remove this firmware update using AMD's directed process, but it was not possible.

As such, we tested the laptop in ‘Manual' Armoury Crate mode which allowed the CPU to operate at its 35W steady-state power draw figure without the unusual throttling behaviour. We also discovered that flipped the laptop into a different orientation can eliminate the throttling behaviour when the laptop understands that it has been flipped. This implies that the throttling limitations are intended or consequential in the firmware update.

Comparison comes from a variety of systems from MSI, Razer, and Lenovo. We are particularly interested in the comparison with the Intel Core i7-1165G7 ‘Tiger Lake' powered Razer Blade Stealth 13 which is realistically a direct competitor for the Ryzen 9 5980HS powered ASUS Flow X13. Comparing the Ryzen 9 chip against a Core i9-10980HK will also be interesting to see how AMD's Zen 3 part goes up against Intel's current mobile flagship.

The Razer Blade Stealth 13 was tested in its ‘Gaming' mode that allowed the Core i7-1165G7 to use aggressive short duration bursts whilst operating at 28W power for long duration all-core loads.  The Lenovo Yoga Slim 7’s Ryzen 7 4800U was set to the higher performance mode that allowed a long duration power of around 25-35W and typically held at 30W according to our logs.

The MSI’s Core i9-10980HK was tested using the ‘Balanced’ power mode that was 45W long duration CPU with a short duration boost power of a little under 50W. We also tested the MSI in ‘Extreme’ mode which allowed the CPU to boost in the order of 100W initially before stabilising down to around 56W long duration.

We tested the ASUS Ryzen 9 5980HS laptop using the ‘Manual’ power mode set to 35W TDP. This allowed us to maintain aggressive short duration boost power delivery of around 60-65W and a 35W long duration operating power output.
