AI 热潮正在挤压手机和电脑的 RAM 供应，想买便宜电子产品的消费者和关注新兴市场的从业者，建议提前了解价格趋势。
内存制造商（仅剩三家大公司）的晶圆产能固定，需分配给DDR（台式机/服务器）、LPDDR（手机/低功耗设备）和HBM（GPU用）。AI数据中心对HBM的需求激增，其晶圆分配比例从2%预计升至2026年底的20%，且每GB HBM消耗的晶圆容量是DDR或LPDDR的三倍以上。内存公司因历史教训倾向于保守扩产，导致消费设备RAM生产受限。这已影响100美元以下智能手机市场，尤其对非洲和南亚地区冲击明显。未来几年，使用内存的消费电子产品价格将显著上涨。
The memory shortage is causing a repricing of consumer electronics
The memory shortage is causing a repricing of consumer electronics David Oks provides the clearest explanation I've seen yet of why consumer products that use memory are likely to get significantly more expensive over the next few years. The short version is that memory manufacturers - of which there are just three remaining large companies - have a fixed capacity in terms of how many wafers they can process at any one time. This fixed wafer capacity is then split between DDR - used in desktops and servers, LPDDR - used in mobile phones and low-energy devices, and HBM - used with GPUs. Until recently, HBM got just 2% of that wafer allocation. The enormous growth in AI data centers has pushed that up to an expected 20% by the end of 2026, and "a single gigabyte of HBM consumes more than three times the wafer capacity that a gigabyte of DDR or LPDDR does". Memory companies have learned from the extinction of their rivals that you should always under-provision rather than over-provision your fabricator capacity. The profit margins and demand for HBM (high-bandwidth memory) will constrain the production of consumer-device RAM for several years. This is already being felt in the sub-$100 smartphone market, which is particularly important to markets like Africa and South Asia.
