ARM 放弃 Cortex ，警示 RISC-V 风险​

Core Viewpoint - ARM has announced a significant strategic adjustment by abandoning the long-standing Cortex brand and restructuring its product line with a new naming system, reflecting its deep insight into future market competition and concerns about the emerging RISC-V architecture as a potential threat [1][3]. Group 1: Brand and Product Line Changes - ARM's Cortex brand, known for its high recognition in the semiconductor industry, will be replaced by a new, simplified naming system to better meet the needs of different market segments and enhance competitiveness in the global chip market [1][2]. - The new product naming system categorizes Compute Subsystems (CSS) based on application areas, including Arm Neoverse for infrastructure, Arm Niva for PC, Arm Lumex for mobile, Arm Zena for automotive, and Arm Orbis for IoT, while retaining the Mali brand for GPUs [2]. Group 2: Concerns about RISC-V - ARM has issued a clear warning regarding the RISC-V architecture, which has gained attention due to its open-source nature, potentially leading customers to choose it over ARM products if its ecosystem continues to grow [3][4]. - Despite RISC-V's current limitations in advanced design support compared to ARM, its development poses a potential threat, especially as ARM raises licensing prices, making RISC-V a more cost-effective alternative for some manufacturers [4]. Group 3: Market Implications - ARM's decision to abandon the Cortex brand and restructure its product line is a crucial response to market changes and competitive challenges, aiming to enhance market adaptability and service precision [4]. - The evolving competitive landscape in the global chip design market may undergo profound changes as ARM implements its new strategy and RISC-V continues to develop [4].
