AMD Unveils Ryzen AI 400 Series for Business Desktops, Featuring Enhanced NPUs

AMD has announced the introduction of its first Ryzen AI desktop processors, marking a significant step in its product lineup. These new processors, known as the Ryzen AI 400-series, are designed for use with the AM5 CPU socket and are intended to replace the previous Ryzen 8000G series. The new chips integrate Zen 5-based CPU cores, RDNA 3.5 GPU cores, and neural processing units (NPUs) capable of performing 50 trillion operations per second (TOPS). This makes them the first AMD desktop chips to meet the requirements for Microsoft's Copilot+ PC label, which supports unique Windows 11 features such as Recall and Click to Do.

The initial release includes six models: the 65 W Ryzen AI 7 Pro 450G, Ryzen AI 5 Pro 440G, and Ryzen AI 5 Pro 435G, along with their low-power 35 W "GE" variants. These processors carry the "Ryzen Pro" branding, indicating their suitability for business environments where device management capabilities are crucial. However, AMD is not offering these chips in boxed versions for the general consumer market. Instead, they are targeted at business PCs that require enhanced graphics capabilities without the need for a dedicated graphics card.

These processors are essentially repurposed laptop silicon, sharing many specifications with the Ryzen AI 300 laptop processors despite their new branding. The Ryzen AI 400-series desktop CPUs feature slightly faster NPUs than their laptop counterparts, with a performance increase from 55 TOPS. However, AMD has not yet provided its top-tier laptop silicon for desktop use, as none of the announced models include the full 12 CPU cores available in the Ryzen AI 9 HX 375 or 370, nor do they feature the Radeon 880M or 890M integrated GPUs. The current models are limited to 8 CPU cores and a Radeon 860M integrated GPU with 8 RDNA 3.5 graphics cores.

AMD's decision to focus on business desktops rather than gaming PCs is influenced by the current economic climate. The cost of fast DDR5 memory has risen significantly, making it financially challenging to build gaming PCs around socket AM5 processors. As a result, the performance-to-cost ratio of desktop integrated GPUs is less appealing, prompting AMD to prioritize business applications for these new chips.

This announcement aligns with AMD's earlier presentations at CES, which highlighted incremental advancements in existing technologies rather than groundbreaking innovations. This conservative approach is partly due to ongoing RAM and storage shortages, as well as intense competition among chipmakers for manufacturing capacity at TSMC.
