AMD brings a big upgrade to Ryzen AI Max 400 series processors
AMD has officially introduced the new Ryzen AI Max 400 series processors, bringing an upgraded version of the “Strix Halo” platform focused on AI workloads and high-end performance. The new chips improve memory support, AI power, and graphics speeds while keeping the same powerful hybrid design introduced with the Ryzen AI Max 300 series.
The biggest change in the Ryzen AI Max 400 lineup is memory support. AMD has upgraded the memory controller to handle up to 192GB of LPDDR5X memory, which is a major jump from the previous 128GB limit. This improvement is especially important for AI developers and users working with large language models and heavy AI tasks.
AMD also allows users to manually divide memory between the system and the integrated graphics. The iGPU can now use up to 160GB of video memory, which could help with demanding AI and graphics workloads.
The Ryzen AI Max 400 series combines up to 16 Zen 5 CPU cores with a large integrated GPU based on the RDNA 3.5 graphics architecture. The built-in graphics feature up to 40 compute units, making these processors powerful enough for gaming, creative work, and AI processing without needing a separate graphics card.
The updated chips also receive small but useful speed improvements. GPU boost clocks now reach up to 3.00 GHz compared to 2.90 GHz on the previous generation. CPU boost clocks now go as high as 5.20 GHz, while the upgraded NPU delivers up to 55 TOPS of AI performance, offering around 10% better AI processing power than before.
AMD introduced three models in the new series. The Ryzen AI Max+ PRO 495 sits at the top with 16 cores, 32 threads, boost speeds up to 5.20 GHz, a full 40 CU GPU, and 55 TOPS AI performance.
The Ryzen AI Max PRO 490 comes with 12 cores and 24 threads, boost speeds up to 5.00 GHz, a 32 CU integrated GPU, and up to 50 TOPS AI performance.
Meanwhile, the Ryzen AI Max PRO 485 features 8 cores and 16 threads with the same 32 CU graphics and 50 TOPS AI engine.
AMD says the new processors are designed for advanced AI development platforms and professional systems with AMD PRO features that compete directly with Intel vPro technology. Consumer versions are also expected later this year.
One of the most important benefits of the new 192GB memory support is the ability to run massive 300B+ parameter AI models directly on supported systems. This could make the Ryzen AI Max 400 series attractive for AI developers, researchers, and workstation users looking for strong local AI performance without relying entirely on cloud hardware.
