近日，知名科技媒体Tech Insights对华为新款搭载麒麟9006C处理器的商用笔记本电脑擎云L540进行了拆解，发现这款5nm芯片实际上是由台积电制造的。此前，华为曾推出搭载该处理器的笔记本电脑，并引发业界关于中芯国际是否已实现5nm芯片量产的猜测。
据了解，麒麟9006C处理器采用5nm制程工艺和8核心架构，最高主频可达3.13GHz。然而，Wccftech的测试结果显示，该处理器的单核和多核性能相较竞争对手仍有较大差距，甚至不如同样采用5nm工艺的高通骁龙8cx Gen 3。
值得注意的是，这款处理器并非华为全新推出的产品。早在2021年，麒麟9006C就在擎云L420笔记本上得到应用。此次拆解结果显示，麒麟9006C与海思麒麟9000处理器采用了相同的BEOL堆栈和工艺节点，属于2020年第35周封装。
尽管目前仍有营销号宣称中芯国际正在研发国产5nm工艺节点，但至今未见实质性成果。此次华为5nm芯片制造之谜的揭晓，无疑为国内芯片产业的发展带来了新的挑战与机遇。

News Title: Huawei’s 5nm Chip Mystery Solved: manufactured by TSMC
Keywords: Huawei, 5nm chip, TSMC
News Content:
Recently, Tech Insights dismantled Huawei’s new commercial laptop, Qingyun L540, which is equipped with the Kirin 9006C processor, and found that the 5nm chip is actually manufactured by TSMC. Previously, Huawei had launched a laptop equipped with the processor, causing speculation in the industry about whether SMIC has achieved mass production of 5nm chips.
It is understood that the Kirin 9006C processor adopts a 5nm process and an 8-core architecture, with a maximum frequency of up to 3.13GHz. However, Wccftech’s test results show that the processor’s single-core and multi-core performance still has a large gap compared to competitors, and even falls behind the similarly 5nm-processed Qualcomm Snapdragon 8cx Gen 3.
It is worth noting that this processor is not a new product launched by Huawei. As early as 2021, the Kirin 9006C was applied in the Qingyun L420 laptop. The dismantling results show that the Kirin 9006C shares the same BEOL stack and process node as the HiSilicon Kirin 9000 processor, belonging to the 35th week of packaging in 2020.
Although there are still marketing accounts claiming that SMIC is developing domestic 5nm process nodes, there has been no substantive progress so far. The revelation of Huawei’s 5nm chip manufacturing mystery undoubtedly brings new challenges and opportunities for the development of domestic chip industry.
