AMD Launches First AI Desktop Chips
AMD just announced its Ryzen AI 400 series, the first desktop CPUs for its AM5 platform with integrated neural processing units (NPUs). The chips are aimed at business PCs, not gaming rigs, signaling a strategic shift to capture the enterprise market for on-device AI acceleration.
The integrated XDNA 2 neural processing unit (NPU) is rated for up to 50 trillion operations per second (TOPS), specifically to meet Microsoft's requirements for "Copilot+ PC" experiences. This allows tasks like running AI assistants and large language models to happen locally, which improves privacy and reduces the need for cloud-based processing. The initial Ryzen AI 400 desktop lineup includes six models, with options for either 65-watt or lower-power 35-watt designs. The top-tier Ryzen AI 7 450G features 8 cores, 16 threads, and can boost up to 5.1 GHz, while the Ryzen AI 5 models come with 6 cores and 12 threads. These processors combine AMD's latest Zen 5 CPU architecture with RDNA 3.5 graphics. The Ryzen AI 7 450G includes Radeon 860M graphics with 8 compute units, while the Ryzen AI 5 models feature Radeon 840M graphics with 4 compute units. Interestingly, the desktop versions are not AMD's most powerful "Strix Point" offerings. The mobile Ryzen AI 400 series goes up to a Ryzen AI 9 HX 475, which boasts 12 CPU cores, a 60 TOPS NPU, and more powerful Radeon 890M graphics with 16 compute units. For now, the Ryzen AI 400 desktop chips will only be available in pre-built systems from major manufacturers like HP, Lenovo, Dell, and Asus. A wider release for DIY PC builders is expected to follow a few months after the initial commercial launch in the second quarter of 2026. The introduction of NPUs by both AMD and Intel marks a significant shift in personal computing. These specialized processors are designed to efficiently handle the unique mathematical operations required for AI workloads, freeing up the CPU and GPU for other tasks.
