A test setup of an ASUS ROG Ally X handheld connected to an AMD Radeon RX 9070 XT external GPU reached an average of 151 frames per second in Cyberpunk 2077. The benchmark was conducted at a resolution of 3440x1440.
Why it matters
Connecting handheld devices to external hardware expands the utility of portable systems, allowing users to leverage desktop-class graphical performance for demanding titles. This configuration demonstrates the viability of modular PC gaming setups.
The system paired an ASUS ROG Ally X, featuring a Ryzen AI Z2 Extreme processor and 24GB of LPDDR5X memory, with a 16GB GDDR6 AMD Radeon RX 9070 XT eGPU. Testing utilized Cyberpunk 2077 version 2.31 with FSR 2.1 upscaling and FSR 3.1 frame generation enabled.
The players
ASUS
A multinational computer hardware and electronics company known for its ROG line of gaming peripherals and handheld devices.
AMD
A semiconductor company that designs high-performance computing processors and graphics cards for both consumer and enterprise markets.
The details
The setup uses a USB4-connected eGPU dock to bridge the handheld to the external graphics card. When connected to an external display, the handheld offloads graphics-heavy rendering workloads from its integrated chip to the dedicated eGPU. FSR 3.1 — a spatial and temporal upscaling technology that creates synthetic frames — was employed to reach the reported frame rates at the 3440x1440 resolution.

The Tech Race
This configuration highlights the ongoing effort to close the performance gap between compact mobile gaming chips and dedicated desktop graphics solutions. By utilizing the USB4 standard, these handhelds now compete with entry-level desktop PCs in demanding gaming benchmarks.
Users with compatible USB4 handhelds can offload intensive graphical tasks to an external GPU for desktop-level resolution and frame rates. This workflow requires both an eGPU dock and a capable external display to realize these performance gains.
The takeaway
This setup illustrates that handheld PCs can successfully act as the primary component of a high-performance desktop gaming rig when paired with an external GPU. Readers should monitor future updates regarding eGPU driver compatibility for mobile-grade processors to see if these gains persist.
