HP ZBook Ultra G3a: 192GB local-AI workstation from 639,100円

The HP ZBook Ultra G3a 16 inch was co-developed by HP and AMD, and it sits at the intersection of two trends the announcement leans on: workstation-grade performance and on-device AI. The machine pairs an AMD Ryzen AI MAX PRO 400-series processor with up to 192GB of unified memory in its maximum configuration, plus the AMD Ryzen AI Max+ PRO 495 for the CPU. That combination is what the company says allows large local AI models, AI agents, and professional applications to run on the machine rather than in the cloud.

HP is also pitching portability alongside that capability. The chassis is 18.4mm thin and weighs roughly 1.9kg, and HP says a new cooling design lifts TDP by up to 81.8%, enabling up to 100W of performance away from a desk. The included USB-C adapter uses gallium nitride (GaN) to deliver up to 180W while staying small and light.

For buyers weighing a purchase, the key question is likely to be how much they value local AI processing versus the price. The headline model starts at 639,100 yen, but HP is also offering a limited-quantity campaign model bundled with the Poly Voyager 4320 UC headset from 575,300 yen, which may shape which configuration professionals actually choose.
