This NPU is the central engine for running on-device AI features, including Windows Copilot+ and HP AI Companion tools. By offloading resource-intensive tasks — such as real-time video effects, language processing, and advanced security checks — directly to the NPU, the CPU and GPU are freed for other workloads. This distributed processing model ensures AI-enhanced productivity tools run with near-zero latency and minimal impact on system performance or battery life.
Snapdragon X Elite Advantages
The HP OmniBook X’s performance is intrinsically tied to the Qualcomm Snapdragon X Elite — a processor that challenges x86’s long-standing dominance in the laptop segment.
Architecture benefits
ARM-based efficiency
The adoption of the ARM instruction set is the core technology enabling the HP OmniBook X’s breakthrough 28-hour battery life. This architecture features less power leakage and superior idle efficiency compared to x86 counterparts. The custom Oryon cores are engineered for high sustained performance at remarkably low thermal design power (TDP).
Dedicated Neural Processing Unit
The HP OmniBook X’s integrated NPU is an ultra-efficient accelerator optimised for the low-precision integer calculations (INT8/INT4) common in large language models and neural networks. This dedicated hardware handles the heavy lifting of modern AI features locally on the device — conserving main CPU power and preserving data privacy without relying on cloud processing.
Always-connected capabilities
The Snapdragon platform’s lineage includes integrated modem technology. While optional configurations may vary, the architecture is inherently designed for always-connected functionality, including integrated 5G support. This ensures high-speed internet access without relying on a Wi-Fi network — a practical advantage for professionals who frequently move between locations.
Performance metrics
Multi-core performance benchmarks
Early benchmarks demonstrate the Snapdragon X Elite rivalling, and in some cases surpassing, the multi-core performance of contemporary Intel® and AMD chips in the ultraportable class. This is achieved at a significantly lower power draw, giving it a distinct advantage for long-duration tasks such as complex data modelling or software compilation.
AI acceleration capabilities
The 45 TOPS NPU ensures AI-powered applications run with remarkable speed. Real-time video encoding and generative AI tools like Paint Cocreator are executed locally, eliminating cloud latency and providing an instantaneous user experience. This level of on-chip acceleration effectively future-proofs the HP OmniBook X for the rapidly expanding ecosystem of AI-enabled professional software.
Thermal design advantages
Thanks to the Snapdragon X Elite’s superior power-per-watt ratio, the HP OmniBook X achieves formidable performance through a highly efficient thermal design. The fan-assisted cooling system — or even a fanless design in lower-TDP configurations — is less taxed than comparable x86 systems, resulting in quieter operation and less heat transfer to the keyboard deck.
Build Quality And Materials Engineering
Engineering excellence in a business laptop does not stop at the silicon. It must extend to the tactile experience and the chassis’s long-term reliability — qualities that matter greatly for professionals who depend on their devices daily.
Premium construction
Designed with frequent travel in mind, the HP OmniBook X balances impressive strength with extreme lightness. Its precision-crafted chassis is made largely from recycled aluminium, providing excellent structural rigidity, a premium aesthetic, and a reduced environmental footprint.
The thoughtful design — including extensive internal weight-saving techniques — creates an incredibly portable form factor, weighing just 2.97 lbs (1.35 kg) for the 14-inch model. The chassis also endures a suite of MIL-STD-810H durability tests, certifying its ability to withstand extremes in temperature, shock, vibration, and altitude.
Sustainable engineering
HP’s prioritisation of sustainability is evident throughout the HP OmniBook X’s design. Internal components — including speaker enclosures and keycaps — utilise up to 50% post-consumer recycled (PCR) plastics. The OmniBook X also carries EPEAT Gold with Climate+ certification, an independent environmental rating confirming the product meets stringent criteria for energy efficiency and a reduced carbon footprint.
Display Technology
The HP OmniBook X is optimised for visual clarity, productivity, and outdoor visibility through its advanced panel and glass technology.
The standard configuration features a crisp 2,240 × 1,400 (2.2K) resolution panel. This resolution provides a significant pixel density increase over standard Full HD, delivering sharp text and detailed graphics without the power penalty of a 4K display. The screen is protected by Corning Gorilla Glass NBT — a durable, scratch-resistant glass engineered specifically for touch-enabled notebooks.
The panel uses a 16:10 aspect ratio, a deliberate choice that provides more vertical screen real estate than the traditional 16:9 format. This reduces the need for constant scrolling through lengthy documents — a practical benefit for professionals working with reports, spreadsheets, or presentations. The panel also reaches brightness levels of up to 400 nits, providing excellent contrast and readability in bright office environments.
For users who prefer the convenience of a larger screen at their desk, pairing the HP OmniBook X with one of HP’s monitors creates an efficient dual-display setup without sacrificing portability when on the move.
