Group 2: HBM Demand and Supply - The HBM supply for 2025 is fully sold out, with HBM revenue experiencing a nearly 50% quarter-over-quarter growth [1][3]. - Micron is shipping HBM in bulk to four customers, including AMD's Instinct MI355X, which is currently in mass production [1][7]. - HBM4 samples have been provided to customers, with mass production expected around mid-2026, which is anticipated to boost revenue and profit [9][18]. Group 3: Market Outlook - Management expects significant growth in HBM bit demand, outpacing DRAM demand growth in 2026, which is positive for revenue and profit [4]. - The overall DRAM bit demand growth rate is projected to reach high double-digit percentages in 2025, while NAND bit demand growth is expected to be in the low double-digit percentage range [3]. Group 4: Profit Margins and Pricing - Despite strong revenue growth, profit margins are under pressure due to a decline in average selling prices driven by consumer product mix [2][12]. - The average selling price of DRAM decreased by a low single-digit percentage, while NAND saw a high single-digit percentage decline [12]. - Management anticipates a recovery in profit margins as the product mix shifts towards higher-margin data center products [18].

Core Insights - Advanced Micro Devices (AMD) has announced its next-generation AI chips, the Instinct MI400 series, which are set to ship next year, aiming to enhance its competitive position against Nvidia in the AI chip market [1][2]. Company Developments - The MI400 chips can be assembled into a server rack called Helios, allowing thousands of chips to function as a unified system, which is crucial for AI applications [2][3]. - AMD's CEO Lisa Su highlighted that the Helios rack operates as a single massive compute engine, positioning it against Nvidia's upcoming Vera Rubin racks [4]. - OpenAI's CEO Sam Altman confirmed that OpenAI would utilize AMD's chips, indicating strong industry interest [2][3]. Competitive Landscape - AMD aims to compete with Nvidia's Blackwell chips by offering lower operational costs and aggressive pricing strategies [5][6]. - Currently, Nvidia holds over 90% of the data center GPU market, but AMD is focusing on capturing a share of the projected $500 billion AI chip market by 2028 [10][19]. - AMD's MI355X chip is reported to have seven times the computing power of its predecessor, enhancing its competitiveness against Nvidia's offerings [14][15]. Market Trends - Major cloud companies are expected to invest hundreds of billions in new data center clusters for AI, with $300 billion planned in capital expenditures this year alone [9]. - AMD's AI chip sales reached $5 billion in fiscal 2024, with expectations of 60% growth in the category this year [19]. Technological Advancements - AMD's chips are designed to excel in inference tasks, which are increasingly important for deploying AI applications, and they feature more high-speed memory compared to Nvidia's chips [13][14]. - The company is integrating its GPUs with CPUs and networking chips from its acquisition of Pensando to enhance the performance of its Helios racks [17].

Core Viewpoint - AMD's Instinct MI325X accelerator faces significant commercial challenges due to limited scalability and shipment delays, especially in comparison to Nvidia's offerings [1][2]. Group 1: Scalability and Performance - The maximum scalable configuration for AMD's Instinct MI325X and MI355X is limited to 8 GPUs, while Nvidia's B200 can scale up to 72 GPUs using NVLink interconnect [2]. - To build a cluster with more than 8 GPUs based on AMD, a shift to a different architecture is required, which reduces scalability [2]. - The MI325X has high power consumption (1000W) and does not show significant performance improvements over the MI300, complicating upgrades from existing platforms [2]. Group 2: Market Reception and Future Prospects - Microsoft expressed disappointment with AMD's GPUs as early as 2024, leading to a lack of follow-up orders, although Oracle and other companies have shown renewed interest due to AMD's price reductions [3]. - If the MI355X is competitively priced and supported by robust software, it may gain some traction, but it will still struggle to compete with Nvidia's rack-scale GB200 NVL72 [3]. - SemiAnalysis suggests that the MI355X could succeed in non-rack scale deployments if it has a competitive total cost of ownership (TCO) and improved software [3].
