AMD unveiled the Ryzen AI Max 400 series, a refresh of the Strix Halo platform. The new chips blend up to 16 Zen 5 cores with a single SoC die that houses a 40‑CU RDNA 3.5 iGPU, a 50‑TOPS NPU, and a 256‑bit LPDDR5X interface. All models carry AMD PRO features that match Intel’s vPro.

Memory sits at the heart of the upgrade. AMD lifted the controller to support up to 192 GB of LPDDR5X, a jump from the 128 GB ceiling on the previous generation. Users can split memory between system and iGPU, giving the GPU a 160 GB pool. The iGPU now tops out at 3.00 GHz, up from 2.90 GHz, while Zen 5 cores peak at 5.20 GHz.

Three variants drive the line: the 495 sports a 16‑core/32‑thread CPU, full 40‑CU iGPU, and a 55‑TOPS NPU; the 490 offers 12 cores and 32 CU; the 485 trims to 8 cores but keeps the same 32‑CU GPU and 50‑TOPS NPU. With 192 GB of memory, the platform can now host 300 B+ parameter LLMs, positioning AMD firmly against NVIDIA in large‑model inference. This refresh underscores AMD’s push into AI workloads traditionally dominated by GPU‑centric solutions, offering a balanced CPU‑GPU NPU stack that appeals to data‑center operators.
