苹果 AI 服务器内部结构首曝：M5 系列芯片、2U 机架，Mac Studio 负责软件控制_我的网站

一 |     Washington, Oct 11 (UNI) The Chinese economy will post the lowest GDP growth in four decades in the current year, barring performance during the initial COVID-19 crisis in 2020, the International Monetary Fund (IMF) said on Tuesday.

"The revisions reflect the downgrade for growth in China, to 3.2 percent in 2022 (the lowest growth in more than four decades, excluding the initial COVID-19 crisis in 2020). COVID-19 outbreaks and lockdowns in multiple localities, as well as the worsening property market crisis, have held back economic activity in China, " the IMF said in its World Economic Outlook.

However, China’s growth is expected to rise to 4.4 percent in 2023, the report added.

COVID-19-related lockdowns have taken a significant toll on China’s economy, particularly in the second quarter of 2022, according to the reports. Particularly, the property sector, which represents the fifth part of the nation’s economy is rapidly weakening, it added.

"A worsening of China’s property sector crisis could spill over to the domestic banking sector and weigh heavily on the country’s growth, with negative cross-border effects," the IMF said.

UNI/SPUTNIK GNK。     8 月 25 日消息，消息源 @hsuchingpo 昨日（8 月 24 日）在 X 平台发布推文，分享了 4 张图片，展示了苹果自研 Apple Silicon AI 服务器内部布局，采用定制 2U 机架，内部设有 4 列硬件，每列包含 8 个计算单元，整机或搭载 32 颗处理器。消息源在配图说明中称：“苹果 M5 服务器”，在网友询问这是否为苹果 Private Cloud Compute（私有云计算）硬件时，表示“大概率是”。消息源还表示该服务器需要搭配 Mac Studio（起到软件控制的作用）使用。从俯视图看，服务器采用定制的 2U（常见服务器尺寸，高度约为 8.89 厘米）机架式机箱。内部设有 4 列结构相同的硬件，每列包含 8 个较小的计算单元，合计 32 个处理器或处理器单元。

二 | 每块电路板位于对应列的外侧，散热器则位于中部；电路板两侧还配有支架，方便快速拆卸和更换。附上相关推文图片如下：照片中的部分电路板已移除散热器。其中一张照片清除了芯片表面的导热膏，露出了芯片顶部的苹果标志。报道无法确认芯片型号，只推测其可能接近 M5 Ultra（M5 Ultra 芯片）的规格。机箱中央设有连接器，连接各列硬件与贯穿整列的主控板。底板中央伸出的连接线通往机箱一端，但目前无法判断这些线缆用于供电、传输数据，还是同时承担两项任务。服务器内部结构围绕气流效率设计。每列硬件的一端配有 1 个风扇，空气从机箱前端流向后端，直接穿过中部散热器的鳍片。列结构的侧面和底板上方由透明塑料罩连接，形成封闭风道，引导气流通过散热区域。
