AMD Unveils Ryzen AI Max 400 Series with Strix Halo Architecture
AMD has introduced the Ryzen AI Max 400 series, built on the new Strix Halo architecture. The chips support up to 192 GB of unified LPDDR5X memory over a 256-bit bus, with the ability to allocate up to 160 GB as video memory for the integrated GPU — enabling local inference of large language models with up to 300 billion parameters.
The flagship Ryzen AI Max+ PRO 495 features 16 cores clocked at up to 5.20 GHz, an integrated RDNA 3.5 GPU with 40 compute units running at up to 3.00 GHz, and an NPU delivering 55 TOPS of AI performance. The lineup also includes the 12-core PRO 490 and 8-core PRO 485, both with 32 GPU compute units. Consumer versions are expected by the end of the year.
