华为麒麟 9050 Pro 芯片的裸片显微照近日首次曝光，展现了这款芯片的核心创新架构。1该芯片由两颗尺寸相同的裸片组成，每颗尺寸为 11.13×10.84 毫米，面积约 120.65 平方毫米，通过高密度垂直互连技术垂直堆叠实现。1这一设计使芯片总面积小于前代麒麟 9030S 的 122 平方毫米，却在如此紧凑的布局下实现了显著的性能跃升。1
晶体管密度的提升是麒麟 9050 Pro 的关键进步。1相比麒麟 9030 Pro 每平方毫米约 1.55 亿个晶体管，新芯片达到约 2.38 亿个，增幅达 55%。1华为芯片专家何庭波表示，这一增幅相当于过去三年依靠几何尺寸缩小所取得的成果总和。1在工艺方面，逻辑裸片采用中芯国际 N+3 工艺，SRAM 裸片采用 N+2 工艺。1
功耗控制方面表现突出。1在性能对齐条件下，该芯片的 NPU 功耗降低 66%、GPU 功耗降低 58%、CPU 性能核功耗降低 41%。1麒麟 9050 Pro 首发于 9 月 7 日，随华为 Mate XT 2 三折叠手机亮相，随后搭载于 Mate 90 Pro Max 典藏版与 Mate 90 RS 非凡大师。1该芯片将移动芯片与苹果的技术差距缩小至约三年。1
Huawei's latest flagship processor, the Kirin 9050 Pro, has achieved a significant engineering milestone through its implementation of logic folding technology, marking the first commercial application of this advanced chip architecture.1 The processor features two identically-sized dies, each measuring approximately 120.65 square millimeters and stacked vertically through high-density interconnect technology.1 Despite the chiplet configuration, the overall die area remains smaller than its predecessor, the Kirin 9030S at 122 square millimeters.1
The vertical stacking approach delivers substantial performance gains in power efficiency and transistor density. Transistor density has increased by approximately 55 percent to 238 million transistors per square millimeter, compared to 155 million in the Kirin 9030 Pro.1 The processor achieves considerable power reductions across multiple components: NPU power consumption dropped by 66 percent, GPU by 58 percent, and CPU performance core power by 41 percent, all while maintaining performance parity with previous generations.1 The logic die utilizes SMIC's N+3 process technology, while the SRAM die employs the N+2 process.1 According to published research, this density improvement equates to the cumulative gains achieved over the preceding three years through geometric scaling alone.1
The Kirin 9050 Pro made its debut on September 7 alongside the Mate XT 2 tri-fold smartphone, subsequently appearing in the Mate 90 Pro Max Collector's Edition and Mate 90 RS Master Crafted variant.1 The chip narrows the technological gap between Huawei's mobile processors and Apple's offerings to approximately three years, compared to a four-year gap with the previous generation.1
