Core Viewpoint - Nvidia is pushing its memory suppliers to exceed the JEDEC official HBM4 benchmark, aiming for a stack speed of 10Gb/s to enhance GPU bandwidth beyond AMD's upcoming MI450 Helios system [2][3]. Group 1: Nvidia's Strategy and HBM4 Development - Nvidia has requested a stack speed of 10Gb/s for its 2026 Vera Rubin platform, which would increase the total transmission rate per stack to 2.56 TB/s, allowing a single GPU to achieve 15 TB/s of raw bandwidth [2]. - The Rubin CPX configuration is designed for demanding inference workloads, reportedly achieving a transmission rate of 1.7 PB per second across the NVL144 rack [2]. - However, achieving 10Gb/s HBM4 is not guaranteed, as higher I/O speeds lead to increased power consumption and stricter timing requirements, which could pressure the underlying chip [3]. Group 2: Supplier Landscape and Competition - SK Hynix remains Nvidia's primary HBM supplier and has completed HBM4 development, preparing for mass production, but has not disclosed specific chip specifications [3]. - Samsung is more aggressive in node migration, transitioning its HBM4 base chip to a 4nm FinFET process to support higher clock speeds and lower power consumption [3]. - Micron has confirmed HBM4 samples with a 2,048-bit interface and bandwidth exceeding 2 TB/s, but has not disclosed support for 10Gb/s [3]. Group 3: AMD's Position and Memory Specifications - AMD's MI450 is still in planning, but it is expected to support up to 432GB of HBM4 memory per GPU, potentially allowing AMD to catch up or surpass Nvidia in raw capacity [4]. - With the CDNA 4 architecture upgrade, AMD aims to leverage the inference advantages of Nvidia's Rubin platform [4]. Group 4: Samsung's HBM3E Certification and Future Plans - Samsung has recently received Nvidia's certification for its fifth-generation 12-layer HBM3E product, marking a significant milestone in the high-bandwidth memory sector [5][6]. - This certification comes after Samsung redesigned the HBM3E DRAM core to address thermal performance issues, which had hindered earlier versions [6]. - Samsung plans to supply HBM4 samples to Nvidia soon, with mass production expected to begin in the first half of 2026 [10].

Core Viewpoint - TSMC is accelerating its expansion in the U.S., with its third Arizona fab (F21 P3) having broken ground in Q2, but it currently meets only 7% of U.S. chip demand [1][2]. Group 1: Expansion and Production Capacity - TSMC's Arizona factory is currently only able to satisfy 7% of the U.S. chip demand, indicating a significant gap in supply [1]. - The company is targeting major clients like NVIDIA, AMD, and Tesla, with AMD's next-generation Venice processor planned for 2nm production at the Fab 21 facility [1]. - TSMC's second Arizona fab, utilizing 3nm technology, has been completed, and the company is working to accelerate its mass production schedule to meet customer demand [2]. Group 2: Advanced Packaging and Technology - TSMC is investing in its first advanced packaging factory in the U.S., expected to begin construction in 2026, which will be connected to its P3 fab [3]. - The new AP1 factory will focus on SoIC (System on Integrated Chip) and CoW (Chip on Wafer) processes, with the final substrate steps likely outsourced to Amkor [3]. - AMD's next-generation EPYC Venice processor is expected to utilize TSMC's 2nm process and SoIC packaging technology [4]. Group 3: Competitive Landscape - Elon Musk confirmed that TSMC will produce Tesla's new AI5 chip, but also noted that Samsung is building a new advanced 2nm fab in Texas specifically for Tesla's next-generation AI6 chip, highlighting strong demand and competition in the U.S. market [2]. - NVIDIA plans to release its Rubin chip next year, which will also incorporate TSMC's SoIC technology, integrating two GPUs on N3P and one I/O Die on N5B [4].
