    Microsoft Scales In-House Maia 300 Accelerators With Marvell for Azure

    Question

    Microsoft Scales In-House Maia 300 Accelerators With Marvell for Azure

    Direct answer

    Microsoft is transitioning its primary Azure cloud inference workloads to proprietary Maia 300 accelerators beginning next year. CEO Satya Nadella confirmed the deployment schedule, which targets reducing capital outlay on merchant GPUs from Nvidia. The architectural transition directly benefits custom ASIC partner Marvell Technology, highlighting hyperscaler determination to optimize inference unit economics by owning the custom hardware layer.
