The OmniBook X and OmniBook Ultra are two of the most capable tiers in HP's unified OmniBook laptop lineup. Both are AI-powered, both are portable, and both target users who want more than a basic machine. But they're designed for different priorities and different budgets.
The OmniBook X is a premium all-rounder — strong performance, excellent battery life, and a competitive price. The OmniBook Ultra is HP's flagship — the best display, the most processing power, and the most advanced features in the consumer lineup. Understanding where they overlap and where they diverge helps you avoid overspending on capabilities you won't use or underspending on a machine that won't keep up with your work.
Here's how they compare across the factors that matter most.
Where They Sit in the OmniBook Lineup
HP consolidated its consumer laptop brands into a single OmniBook family with numbered tiers. The OmniBook 3 and 5 cover everyday and mainstream computing (replacing the former Pavilion line). The OmniBook X occupies the premium mid-range tier, replacing what was previously Envy. The OmniBook Ultra is the flagship, replacing Spectre.
Both the X and Ultra are available in clamshell (standard laptop) and Flip (360-degree convertible) configurations. Both include dedicated neural processing units (NPUs) for on-device AI and support Microsoft Copilot+ PC features. The differences are in how far each one pushes display quality, processing power, and premium design.
Display
This is one of the clearest distinctions between the two.
The OmniBook X features a 14-inch IPS display at 2.2K resolution (2240 × 1400) with 300–400 nits of brightness depending on configuration. It's a sharp, capable screen that handles everyday productivity, streaming, and web browsing well. Touch options are available on both clamshell and Flip models.
The OmniBook Ultra steps up to a 14-inch OLED display at 3K resolution with up to 500 nits of brightness. The difference is visible — OLED delivers deeper blacks, higher contrast ratios, and richer colour accuracy than IPS. For creative professionals who work with photos, video, design, or any colour-sensitive content, the Ultra's display is a meaningful advantage. The Ultra Flip model adds pen input with HP's rechargeable stylus, making it a practical choice for digital sketching and document annotation.
If your work is primarily text-based (documents, email, web, spreadsheets), the OmniBook X's display is more than sufficient. If visual quality matters for your workflow or you simply want the best screen HP offers in a consumer laptop, the Ultra justifies the premium.
Performance and Processor Options
Both tiers have evolved since their initial 2024 launch and are now available with multiple processor options depending on the configuration.
The OmniBook X is available with Qualcomm Snapdragon X, Intel Core Ultra, and AMD Ryzen AI processors, depending on the model. The Snapdragon X variants are particularly strong on power efficiency and battery life. Intel and AMD options offer broader software compatibility and stronger multi-threaded performance for heavier workloads. All variants include NPUs for on-device AI processing.
The OmniBook Ultra features Intel Core Ultra (including Panther Lake processors in 2026 models with up to 85 TOPS of NPU performance) and AMD Ryzen AI options. The Ultra's processors are positioned at the higher end of each platform's range, delivering more sustained performance under heavy workloads — multiple demanding applications running simultaneously, video editing, large file processing, and content creation.
In practical terms: the OmniBook X handles everyday productivity, web browsing, video calls, and moderate multitasking comfortably. The Ultra has more headroom for sustained, processor-intensive work where the extra performance translates to noticeably faster results.
Battery Life
Battery life favours the OmniBook X, particularly in Snapdragon X configurations. HP rates the OmniBook X at up to 26 hours of video playback on Snapdragon variants — among the longest battery life in any current laptop. Even with Intel or AMD processors, the X delivers strong all-day performance.
The OmniBook Ultra, with its brighter OLED display and more powerful processors, draws more power. HP rates it at up to 20 hours of video playback, which is still excellent — but the difference is noticeable if battery life is your top priority. The Ultra does offer fast charging, reaching 50% in approximately 30–45 minutes depending on configuration.
If you frequently work away from outlets — long flights, full days at conferences, extended café sessions — the OmniBook X's battery advantage is worth considering. If you're typically near a charger or value the Ultra's other features more than the extra battery hours, the trade-off is manageable.
Audio and Webcam
The OmniBook Ultra includes quad speakers (compared to the X's dual speakers), which delivers noticeably fuller sound for media playback, video calls, and presentations. It also features a higher-resolution webcam — 9 MP with IR for Windows Hello facial recognition — compared to the X's 5 MP IR webcam.
For users who rely heavily on video conferencing or consume media without external speakers, the Ultra's audio and camera upgrades are practical improvements. For general use with occasional calls, the OmniBook X's dual speakers and 5 MP webcam are capable and functional.
Build and Design
Both the OmniBook X and Ultra feature aluminium construction, slim profiles, and full-size backlit keyboards. Both incorporate recycled materials in their chassis and carry energy efficiency certifications.
The OmniBook X is available in silver and white colour options and tends to be slightly lighter and thinner. The Ultra is available in silver (clamshell) and dark grey (Flip), with a build that prioritizes premium feel and material quality.
The OmniBook X offers more physical ports than the Ultra in most configurations — a practical advantage if you connect multiple peripherals without a dock. The Ultra's port selection is more streamlined, reflecting its thinner design.
Connectivity and Ports
The OmniBook X typically includes more USB-C and USB-A ports, making it more convenient for users who regularly connect external storage, displays, or accessories without a hub. Both models support Wi-Fi 6E (some configurations support Wi-Fi 7), Bluetooth 5.3 or later, and USB-C charging.
The OmniBook Ultra favours a cleaner port layout with fewer physical connections, which contributes to its thinner profile. If you use a docking station at your desk, this is a non-issue. If you depend on plugging in multiple devices directly, the X's port count gives it an edge.
AI Features
Both the OmniBook X and Ultra include HP AI Companion for task automation and productivity assistance, Poly Camera Pro for AI-enhanced webcam features (background blur, auto framing, lighting correction), Windows Copilot+ capabilities on qualifying models, and AI-powered noise cancellation for calls and meetings.
The Ultra's higher-TOPS NPU provides faster on-device AI processing, which benefits tasks like real-time transcription, local AI model inference, and AI-assisted creative tools. For most current AI features (Copilot, noise cancellation, smart camera), both models perform capably. As on-device AI applications become more demanding over time, the Ultra's more powerful NPU provides more headroom for future capabilities.
Which One Should You Choose?
The OmniBook X is the better choice if you want premium performance at a more accessible price, battery life is a high priority (especially the Snapdragon X configurations), you need a good selection of ports without a dock, your work is productivity-focused — documents, web, email, calls, moderate multitasking — and you want a capable, well-built AI laptop without paying flagship prices.
The OmniBook Ultra is the better choice if display quality matters for your work — design, photography, video editing, or colour-sensitive tasks, you need sustained performance for demanding multi-application workflows, you want the best webcam and audio for video conferencing, you value premium build materials and design, or you want the highest NPU performance for current and future AI capabilities.
Both are excellent machines. The OmniBook X is one of the strongest value propositions in HP's lineup — it delivers a premium experience at a competitive price, with standout battery life. The Ultra is for users who need the best HP offers and are willing to pay for it. Neither is a wrong choice; the right one depends on what you prioritize.
