半导体行业观察·2025-11-11 01:06Core Viewpoint - The article discusses the evolution of CPU architectures, emphasizing the coexistence of multiple architectures within single systems to handle diverse workloads, particularly in the context of the transformative impact of artificial intelligence (AI) on the industry [2][3]. Group 1: Evolution of CPU Architectures - Historically, x86 architecture, developed by Intel and AMD, has been the dominant choice for PCs and general servers, but it now coexists with RISC architectures, often within the same system or SoC [5][7]. - Arm architecture has become the leading processor architecture across various fields, including mobile devices and IoT, due to its efficiency and extensive hardware and software ecosystem [5][6]. - RISC-V, an open-source ISA, is gaining traction but still lags in software support compared to Arm and x86, with an expected shipment of around 1 billion cores in 2024, primarily for deep embedded applications [8]. Group 2: Market Dynamics and Trends - The demand for performance efficiency driven by AI is prompting companies to develop diverse CPU architectures and configurations, with AMD and Intel creating different performance levels of x86 CPUs for servers [11]. - Arm is expanding its ecosystem by introducing a complete pre-validated compute subsystem and fostering innovation among industry leaders to develop custom Arm-compatible CPU designs [11]. - The semiconductor industry is transitioning towards heterogeneous computing solutions, where multiple CPU architectures will increasingly work together within the same chip design, reflecting a shift in focus from which architecture will prevail to how they can collaborate effectively [11].
