An investor analyzes Micron (MU) versus SanDisk (SNDK) as memory chip plays in the AI boom. MU offers broader exposure across HBM, DRAM, and NAND with $414.6B quarterly revenue and strong data center margins, while SNDK focuses on NAND/SSD with $89.65B revenue and 372% YoY growth. The choice depends on whether HBM or NAND will drive the next phase of memory profits.
A discussion on X about potential shifts in HBM (High Bandwidth Memory) demand for AI systems. The analysis suggests that rather than continuously increasing HBM capacity per GPU, future designs may use smaller HBM stacks combined with interconnect technologies like NVLink to distribute memory across larger clusters. This could pressure HBM wafer consumption by 2028 as new production capacity from SK Hynix, Micron, and Samsung comes online, though long-term contracts and pricing may protect memory manufacturers' margins.
A ByteDance group discussion analyzing AI industry trends covers programmer career prospects amid AI displacement, showing value comes from building abstraction layers rather than executing code. It also discusses Nvidia's shift toward direct optical engine procurement, disrupting traditional module suppliers, and how DeepSeek's reduced HBM requirements paradoxically increase storage value while expanding overall AI capex.
