Summary
IFA 2026 brought AMD’s first clear look at “Sundae” laptops—early HP ZBook models using Ryzen AI Max 400 chips with up to 190GB of unified memory.
AMD says the systems are built for on-device AI and some gaming, but it offered no meaningful benchmarks beyond a stage demo of Microsoft Flight Simulator.
The top Ryzen AI Max 495 uses Zen 5 with 16 cores and 32 threads, while the lineup’s Radeon 8065S GPU appears related to the prior Strix Halo generation.
Acer and Lenovo also showed limited Ryzen AI Max 400 business PCs, extending AMD’s Halo push after its first IFA reveal of a Ryzen AI Halo mini-PC tied to Microsoft’s Project Zenith.
Nvidia plans to launch ARM-based RTX Spark PCs in October with partners including HP, Dell, Asus, Lenovo, Acer, MSI and Microsoft, giving it a broader device lineup than AMD has shown so far.
