About this tag
The npu computing tag examines how neural processing units relate to Windows AI features and Copilot+ PCs. Current coverage focuses on an important distinction: an NPU can support compatible, developer-accessible models designed for on-device execution, but its presence does not automatically make every AI feature run locally or respond faster. In particular, Outlook Copilot is described as a Microsoft 365 service that relies on large language models and Microsoft Graph data. This tag is useful for understanding the practical limits of NPU hardware claims, separating on-device Windows capabilities from cloud-based Microsoft services, and evaluating what Copilot+ PC hardware actually changes for users.

    Copilot+ PCs Don’t Make Outlook Copilot Faster

    HP’s July 31 Outlook explainer gets the core value proposition right—Outlook combines mail, calendar, contacts, tasks, and Teams scheduling—but its most consequential hardware claim does not hold up: an HP Copilot+ PC does not make Copilot in Outlook run locally or inherently deliver faster...
