HP Unveils 2 OmniBook Laptops With RTX Spark and Up to 128GB RAM

Q: With massive local AI power, what hidden price tag awaits consumers craving HP's ultimate OmniBook experience this fall?

The hidden price tag is that consumers still do not know HP’s actual asking price, but all signs point to a very expensive premium tier. HP said the OmniBook Ultra 16 and OmniBook X 14 will go on sale this fall, likely in the broader October 2026 RTX Spark launch window, yet it has not announced pricing. That is the clearest unanswered cost for buyers eyeing the full local-AI configuration. Outside estimates suggest the top RTX Spark N1X class could start around $2,899, with broader reporting placing these systems roughly in the $2,500 to $3,000 range at minimum. That would fit the hardware on offer: up to 128GB of LPDDR5X unified memory, up to 2TB of SSD storage, high-end OLED panels, and as much as 1 petaflop of FP4 AI performance in the Ultra 16. There is also a practical “price” beyond dollars. Buyers are effectively paying an early-adopter premium for one of the first Windows-on-Arm laptops using Nvidia’s new RTX Spark platform. Real-world performance, app compatibility, battery life, and thermal behavior under sustained AI or gaming workloads remain unproven until retail reviews arrive. So the likely answer is a steep flagship-laptop bill—probably several thousand dollars for high-end configurations—combined with the uncertainty that comes with buying into a brand-new PC platform before final pricing and independent testing are available.

HP added two RTX Spark laptops to its OmniBook line — the OmniBook Ultra 16 and OmniBook X 14 — with both supporting up to 128GB LPDDR5X memory and 2TB SSD storage.
Both are among the first laptops announced with Nvidia’s second RTX Spark N1X option, pairing an 18-core CPU with a 5,120-core Blackwell RTX GPU; buyers can also choose a 20-core CPU and 6,144-core GPU version.
The 16-inch Ultra targets performance, with HP claiming up to 1 PFLOP of FP4 AI throughput, a 3K 120Hz OLED touchscreen, a 99Wh battery rated up to 17 hours, and a new airflow-focused hinge design.
The 14-inch X 14 emphasizes portability at 1.71 kg and 13.53 mm, while still offering a 3K 120Hz OLED display, dual-fan cooling, and an 80Wh battery rated up to 15 hours.
Both models are due this fall with Wi-Fi 7, Bluetooth 6.0, dual 40Gbps USB-C ports and USB-A, but HP did not disclose pricing — a pattern seen across several RTX Spark launches at IFA 2026.
