The estimated total cost for the data center is around $350 billion to $500 billion, with GPU servers accounting for approximately 57.4% of the costs, translating to about $120 billion [2][3]. - As part of the agreement, Meta will acquire 160 million shares of AMD's certified stock, valued at approximately $33 billion based on current stock prices [4]. - Meta has faced supply chain issues with Nvidia, prompting a diversification strategy that includes exploring Google's TPU and reallocating its own CoWoS capacity to mitigate risks and optimize total cost of ownership (TCO) [5]. Group 2 - Hynix's HBM4 is experiencing issues, with a necessary modification to the photomask for the 12nm base die, potentially delaying supply by over a quarter [7]. - Citron has announced a short position on SanDisk, citing two main reasons: the memory industry is cyclical and will eventually peak, and Samsung is beginning to compete with SanDisk in the SSD market, suggesting that current supply tightness is a temporary issue related to Samsung's yield problems in another product line [9][10]. - The memory sector is becoming a bottleneck for AI, with increasing demands for bandwidth and capacity. By 2030, the architecture for AI memory will evolve beyond the current HBM+DRAM+SSD setup, necessitating technological upgrades to meet the needs of AI applications [11].
