AMD’s first 192GB laptop reaches reviewers with Ryzen AI Max+ PRO 495

The HP ZBook Ultra G3a mobile workstation has reached reviewers, featuring 192GB of unified memory and an AMD Ryzen AI Max+ PRO 495 processor. This hardware targets the top of the local AI laptop market by providing massive memory capacity for on-device processing. Additionally, Perplexity has launched Portable Computer for Windows, a local AI agent designed for multistep tasks. This software requires RTX GPUs with at least 24GB of VRAM to run entirely on the local GPU.
