Reference TimelineLast updated MAY 23
SUMMARY

AMD announced the Ryzen AI Max PRO 400 series processors on May 23, 2026, targeting commercial AI PCs and workstations, an upgrade to the "Strix Halo" codenamed 300 series. As of May 23, 2026: These processors feature Zen 5 CPU cores, RDNA 3.5 graphics, and XDNA 2 NPU architecture, with the flagship PRO 495 boasting 16 cores, up to 5.20 GHz boost, 192GB LPDDR5X memory support, and 55 TOPS of NPU performance. Systems with these new processors are slated for a Q3 2026 launch from partners like ASUS, HP, and Lenovo, building on the Ryzen AI 400 Series and Ryzen AI PRO 400 Series desktop processors launched on March 2, 2026, which offer up to 50 TOPS for on-device AI acceleration and support Microsoft Copilot+ PC experiences. However, the Ryzen AI 400 and Ryzen AI Pro 400 desktop processors for the AM5 platform have a limited 12 usable PCIe 4.0 lanes, potentially forcing discrete GPUs to operate in x8 mode when an M.2 NVMe SSD is installed.
