The Horizon Breaker: A Vision for Ultra-Wide Portable Power
In an era dominated by commercial handhelds like the Steam Deck and ROG Ally, a pioneering Bilibili creator, PureDIY, has shattered expectations by crafting a custom PC gaming handheld with an audacious 32:9 ultra-wide display. This isn’t just another portable console; it’s a testament to enthusiast innovation, packing the raw power of AMD’s Ryzen Z2 Extreme into a form factor previously unimaginable. This article dives deep into the engineering marvel, exploring its design, performance, and the implications for the future of portable PC gaming.
Why ‘Horizon Breaker’?
The term ‘Horizon Breaker’ perfectly encapsulates this DIY project. It’s not just about a wider screen; it’s about breaking conventional form factor limits, pushing the boundaries of what’s possible in portable PC gaming, and expanding the visual horizon for players on the go. This device challenges the status quo, much like the Ryzen Z2 Extreme challenges performance expectations, setting a new benchmark for optimal component synergy in a portable chassis.
The Engineering Marvel: Inside PureDIY’s Custom Creation
PureDIY’s creation is a masterclass in custom hardware integration. At its core, this Windows-based ultrawide handheld is driven by the AMD Ryzen Z2 Extreme APU, a chip synonymous with flagship performance in today’s leading commercial handhelds. The device features a nearly 12-inch touchscreen display with an improbable 32:9 aspect ratio, a monumental feat of display sourcing and integration that even surpasses the length of a car’s rearview mirror. The custom chassis is meticulously designed to house all components, providing essential I/O ports and side ventilation, alongside a clever kickstand for tabletop play. A key design innovation includes detachable controllers, offering versatility akin to hybrid consoles, all while balancing the complex demands of optimal component synergy.
The Powerhouse Within: AMD Ryzen Z2 Extreme
The choice of the Ryzen Z2 Extreme APU is pivotal to this handheld’s high-performance aspirations. This flagship Zen 5-based 8-core/16-thread processor, featuring 16-core Radeon RDNA 3.5 graphics, represents the pinnacle of current handheld silicon, as revealed at CES 2025. Its ability to deliver significant performance gains, particularly at higher TDPs like those seen in devices like the Lenovo Legion Go 2, is what allows this custom device to run demanding PC titles effectively. The Z2 Extreme’s architecture, with its enhanced AI technologies and ray-tracing accelerators, ensures that even a bespoke system can handle modern gaming workloads, establishing a verifiable benchmark for portable power.

The 32:9 Canvas: A New Perspective on Portable Gaming
The nearly 12-inch 32:9 touchscreen is arguably the most distinctive feature of PureDIY’s handheld. This ultra-wide aspect ratio fundamentally changes the gaming experience, offering an expansive field of view particularly well-suited for genres like racing games, where peripheral vision enhances immersion. PureDIY enthusiastically noted the excitement of racing games on this device, and its considerable length, exceeding even a forearm, certainly provides a unique canvas. Beyond gaming, the extended display length proves surprisingly versatile for productivity tasks such as video and audio editing, effectively transforming the handheld into a compact mini PC. However, this unique aspect ratio also introduces challenges, primarily around game compatibility and optimization, as not all titles natively support 32:9 without black bars or UI scaling issues. The lack of widespread ultra-wide support in the handheld space (though emerging, e.g., Silksong) means this DIY project is ahead of its time, pushing boundaries that commercial devices like the ThinkBook Plus Gen 6 with its rollable OLED are only beginning to explore.
Ultra-Wide (32:9) Handheld Gaming: The Trade-offs
Pros
- Unparalleled immersion in racing and simulation games, leveraging expanded peripheral vision.
- Enhanced strategic awareness due to a wider field of view.
- Increased screen real estate for efficient multitasking and demanding productivity applications.
- Unique ‘cinematic’ visual experience for supported titles, offering a distinct aesthetic.
- Future-proof design as ultra-wide support continues to grow in the gaming industry.
Cons
- Limited native game support for 32:9, often resulting in black bars, stretched UI, or complex workarounds.
- Larger device footprint impacts portability and ergonomic comfort for extended use.
- Potential for increased power draw from the larger display area, affecting battery longevity.
- Higher cost and complexity in sourcing and integrating custom ultra-wide panels.
- Less ‘plug-and-play’ experience compared to standard aspect ratio handhelds, requiring more user customization.
Performance Expectations: Benchmarking the Bespoke
While direct benchmarks for PureDIY’s custom handheld are not yet available, we can infer its formidable performance capabilities by examining the Ryzen Z2 Extreme’s output in commercially available devices. The MSI Claw A8, the first to launch with the Z2 Extreme, and the Lenovo Legion Go 2, also featuring this powerful APU, consistently demonstrate the Z2 Extreme’s ability to deliver smooth framerates in demanding AAA titles. For instance, the Claw A8 achieved 16.27 FPS in Cyberpunk 2077 (1080p high, 17W) and 65.12 FPS in GTA V (720p high, 17W), while the Legion Go 2 hit 60 FPS in Marvel’s Midnight Suns at medium settings. The custom nature of PureDIY’s build, however, opens avenues for unique optimizations in cooling and power delivery, potentially unlocking even greater sustained performance beyond these verifiable, tested framerates.
