Core Viewpoint - Xiaomi's response to rumors about the玄戒O1 being a custom chip from Arm clarifies that it is not true, emphasizing that the chip was independently developed by Xiaomi's team without using Arm's complete solutions [2][3]. Group 1: Development and Design - The玄戒O1 is a 3nm flagship SoC that took over four years to develop, with the CPU and GPU based on Arm's latest IP standards, but the overall design was completed independently by Xiaomi's team [3]. - The CPU of玄戒O1 features a super-large core with a maximum frequency of 3.9GHz, significantly exceeding industry standards, achieved through numerous innovations and hundreds of layout iterations [3]. - Xiaomi's team redesigned over 480 standard cell libraries for the CPU, which is nearly one-third of the 3nm standard cell library, and implemented edge power supply technology and self-developed high-speed registers to meet the challenging design goal [3]. Group 2: Performance and Future Plans - Testing by various media outlets indicates that the CPU and GPU of玄戒O1 have reached first-tier performance and power efficiency [3]. - Xiaomi acknowledges that this is their first flagship SoC and commits to continuous improvement in chip development over the next five, ten, or even twenty years [3]. - The company also highlights its ongoing efforts in baseband development, stating that the玄戒T1 chip includes a fully integrated independently developed 4G baseband [3].
小米:玄戒O1不是向Arm定制的

目前,也有诸多专业媒体对玄戒O1进行了详尽的测试,可以看到CPU和GPU都真正达到了第一梯队的 性能与功耗。当然,这是小米公司第一次推出旗舰SoC,一定还有不足的地方,小米公司会坚定在芯片 这条路上不遗余力,无论五年、十年还是二十年。 微信公众号"小米公司"5月26日消息,小米就15周年产品答网友问。 网传玄戒O1是向Arm定制的芯片,是真的吗? 先说结论:不是。这完全是谣言,玄戒O1不是向Arm定制的,研发过程中,也没有采用Arm CSS服务。 玄戒O1是小米玄戒团队,历时四年多自主研发设计的3nm旗舰SoC,其中基于Arm最新的CPU、GPU 标 准IP授权,但多核及访存系统级设计、后端物理实现完全由玄戒团队自主设计完成,并非网传采用Arm 提供的完整解决方案,所谓"向Arm定制芯片"更是违背事实的无稽之谈。 小米玄戒O1的CPU超大核心,最高主频达到3.9GHz,这远超业界标准设计。能够取得如此成绩,是玄 戒团队诸多创新和数百次版图迭代优化的结果。举个例子,玄戒O1在CPU部分重新设计了超过480种标 准单元库,这一数字几乎达到了3nm标准单元库近三分之一的数量。同时还创新使用了边缘供电技术以 及自研高 ...
