HP has announced its new ZBook Ultra G3a, a 16-inch mobile workstation built around AMD’s Gorgon Halo platform, targeting professionals running intensive local AI tasks with up to 192GB of unified memory and support for large language models.
HP has revealed pricing for its ZBook Ultra G3a, a 16-inch mobile workstation built around AMD’s Gorgon Halo platform. The machine is positioned for professionals running demanding local AI workloads, and HP says the top configuration can support up to 192GB of unified memory, with as much as 160GB assignable as VRAM. The pricing, first highlighted by Notebookcheck and visible through HP’s local AI calculator, suggests the system is aimed squarely at buyers who need workstation-class memory bandwidth rather than mainstream notebook value. According to HP’s product materials, the device is also intended to support advanced on-device AI tasks, including large language models.
The entry configuration pairs an AMD Ryzen AI Max+ PRO 490 with 64GB of RAM, a 512GB SSD and a Full HD display, priced at $3,899. A second model with the Ryzen AI Max+ PRO 495, 128GB of RAM and the same storage and display specification is listed at $5,999. The highest-end version, again using the Ryzen AI Max+ PRO 495 but with 192GB of RAM, rises to $7,449. Notebookcheck notes that HP has also signalled further display options, including 4K IPS and 2.8K OLED panels with a 120Hz refresh rate, which would broaden the line beyond the base Full HD configuration.
HP’s launch announcement frames the ZBook Ultra G3a as a machine for what it calls the era of agentic AI, with support for local execution of very large models and bundled Perplexity software. The company says the system can run 300-billion-parameter language models locally and comes with Perplexity Computer, including integration for Autodesk Revit. That positioning helps explain the aggressive memory ceilings and the emphasis on unified memory, which allows system memory to be allocated more flexibly between conventional computing tasks and graphics-heavy workloads.
Beyond the pricing, StorageReview reports that HP has also reworked the cooling system to raise thermal design power to 100W, compared with 55W in earlier ZBook Ultra models. The outlet says the chassis measures 356 x 240 x 17.9mm, weighs 1.9kg and includes a 96Wh battery that can be charged through Thunderbolt 4 at 180W. Taken together, the specifications suggest HP is trying to balance portability with the higher sustained power draw required for AI development, content creation and other workstation uses.
