The HP OmniBook Ultra 16 is priced from $3,199.99 and the OmniBook X 14 from $2,999.99, with both RTX Spark laptops due at HP.com on October 16. HP describes the Nvidia platform as one built to run larger AI models locally, without a cloud dependency, inside a slim Windows laptop.
HP says the HP OmniBook Ultra 16 will also be sold at Best Buy stores and BestBuy.com, while the X 14 is headed to Costco.com, Micro Center, Walmart and other US retailers. Pricing and availability are subject to change without notice, the company adds.
The $200 gap separates a 16-inch machine from a 14-inch one. According to HP, the HP OmniBook Ultra 16 pairs a 16-inch 3K OLED display, certified to VESA DisplayHDR True Black 1000, with a 99 Wh battery rated for up to 17 hours. HP also lists configurations with up to 128 GB of unified memory and up to 1 petaflop of FP4 AI performance. It has not said which configuration the $3,199.99 starting price covers, so the 128 GB tier is best read as a ceiling rather than the entry model.
The X 14 trades some endurance for size. HP rates its battery at up to 15 hours, against 17 for the larger model, and has published no memory or AI-performance figures for it. It also uses an OLED panel, and HP gives it the same display certification.
Two other items from the same HP update shape who these machines are for. HP is bringing Perplexity Computer to its consumer PCs, with a one-month Perplexity Pro trial on eligible new and existing devices starting in November 2026. At Microsoft's event on October 7, Satya Nadella and Jensen Huang showed Windows running on the HP ZGX Fury, a workstation built on Nvidia's GB300 Grace Blackwell Ultra Desktop Superchip. HP gave no price for the ZGX Fury and points interested buyers to its sales representatives.
Because the Perplexity trial starts a month after the laptops go on sale, early buyers of the HP OmniBook Ultra 16 get the hardware first and the bundled assistant later.
