SteamOS 3.9 Transforms GMKtec EVO X3 Into a 1440P Rig

The GMKtec EVO X3, powered by SteamOS 3.9, showcases how compact devices can deliver a robust gaming experience. Highlighted by ETA Prime, this mini PC combines the AMD Ryzen AI Max Plus 395 CPU with a Radeon 860S iGPU, using a unified memory architecture to eliminate traditional CPU-GPU bottlenecks. With up to 96 GB of memory allocated to the iGPU, the EVO X3 handles demanding games like Cyberpunk 2077 and Elden Ring at 1440p with impressive stability. Its built-in BIOS power modes, Quiet, Balanced and Performance, offer users the flexibility to optimize performance for gaming or other workloads, making it a versatile option for enthusiasts.

In this guide, you’ll explore how SteamOS 3.9 enhances gaming performance through features like FidelityFX Super Resolution (FSR), which boosts frame rates and visual quality at higher resolutions. Gain insight into the EVO X3’s dual-fan cooling system and vertical design, which ensure efficient thermal management during extended sessions. Additionally, discover how its dual-boot capability broadens its functionality, allowing users to switch between SteamOS and other operating systems. This breakdown provides a detailed look at the EVO X3’s strengths and limitations, helping you assess its potential as a compact gaming solution.

Hardware Highlights: Compact Yet Powerful

The GMKtec EVO X3 is built to impress with its innovative hardware. At its core is the AMD Ryzen AI Max Plus 395 CPU, a 16-core, 32-thread processor capable of reaching clock speeds of up to 5.19 GHz. This is complemented by 128 GB of unified memory running at an impressive 8,000 MT/s, with up to 96 GB allocated to the Radeon 860S iGPU. The unified memory architecture eliminates traditional bottlenecks, allowing faster and more efficient data sharing between the CPU and GPU, which is critical for gaming performance.

Thermal management is another area where the EVO X3 excels. A dual-fan cooling system ensures stable performance even during extended gaming sessions, while its vertical design not only saves desk space but also enhances airflow. The BIOS offers three distinct performance modes, Quiet, Balanced and Performance, allowing users to tailor the system’s behavior to their specific needs. This flexibility ensures that the EVO X3 can adapt to a variety of use cases, from casual gaming to demanding workloads.

SteamOS 3.9: A Gaming-Optimized Operating System

The EVO X3 runs on SteamOS 3.9, a Linux-based operating system specifically designed for gaming. Recent updates to SteamOS and Mesa drivers have significantly improved performance, particularly for AMD hardware, making the EVO X3 a strong contender in the mini PC gaming market. Unlike many gaming PCs that rely on third-party tools for power management, the EVO X3 integrates these controls directly into its BIOS, offering a streamlined and user-friendly experience.

One of the standout features of SteamOS is its support for FidelityFX Super Resolution (FSR), an advanced upscaling technology that enhances both performance and visual quality. FSR is particularly effective at higher resolutions like 1440p and 4K, making the EVO X3 an excellent choice for gamers who value smooth gameplay and sharp visuals. This integration of hardware and software ensures that the EVO X3 delivers a gaming experience that is both powerful and efficient.

Gaming Performance: Impressive Results at 1440p

The GMKtec EVO X3 delivers remarkable gaming performance, particularly at 1440p resolution. Its Radeon 860S iGPU, combined with FSR, allows it to handle demanding titles with ease. Below is a breakdown of its performance across popular games:

• Cyberpunk 2077: Runs on high preset with FSR quality mode, achieving frame rates in the high 70s FPS range.
• Horizon Zero Dawn Remastered: Smooth visuals on very high preset with FSR quality mode.
• Mortal Kombat 1: Maintains a steady 60 FPS on very high preset without requiring FSR.
• Spider-Man 2: Delivers high 80s FPS on very high preset with FSR quality mode enabled.
• Doom Eternal: Handles VRAM-heavy tasks effectively on high preset with FSR balanced mode.
• Elden Ring: Achieves a consistent 60 FPS on maxed-out settings without upscaling.
• Forza Horizon 6: Averages 78 FPS at 1440p ultra settings and 68 FPS at 4K ultra settings with FSR quality mode.

While the Radeon 860S iGPU performs admirably for a mini PC, it cannot match the raw power of dedicated GPUs equipped with faster memory like GDDR6. However, the inclusion of FSR allows the EVO X3 to punch above its weight, delivering a gaming experience that is impressive for its size and form factor.

Challenges and Considerations

Despite its many strengths, the GMKtec EVO X3 is not without its limitations. Its integrated GPU, while powerful for its category, falls short when compared to high-end discrete GPUs. This makes it less suitable for gamers who demand the absolute best in graphical performance. Additionally, its premium price point may deter casual gamers, positioning the EVO X3 as a product primarily for enthusiasts or professionals who value its unique blend of features.

The EVO X3’s origins as an AI workstation are evident in its design and cost. While this versatility is a strength, it may not appeal to those seeking a device solely for gaming. However, the inclusion of dual-boot capability adds a layer of flexibility, allowing users to install alternative operating systems alongside SteamOS. This feature broadens its appeal, making it a viable option for users who require a multi-purpose device.

Setting a New Benchmark for Mini PCs

The GMKtec EVO X3 stands out as a compelling option in the mini PC market, blending the capabilities of an AI workstation with impressive gaming performance. Its AMD Ryzen AI Max Plus 395 CPU, Radeon 860S iGPU and unified memory architecture work in harmony to deliver exceptional results, particularly at 1440p resolution. The integration of SteamOS 3.9 and updated Mesa drivers further enhances its gaming potential, providing a streamlined and optimized experience.

While its high price and niche appeal may limit its audience, the EVO X3 is an intriguing choice for enthusiasts seeking a compact, high-performance gaming machine with the added benefit of dual-boot flexibility. It may not replace high-end gaming rigs, but it sets a new standard for what mini PCs can achieve, offering a glimpse into the future of compact computing.
