然而，本轮涨价与以往周期最大的不同在于一个关键变量——HBM（高带宽内存）的爆发式增长。AI芯片（如英伟达H200/B200）对HBM的需求是传统DRAM的数倍甚至数十倍。三大原厂将大量先进制程产能转向HBM，挤占了原本用于生产手机LPDDR（低功耗内存）的产能。这种“结构性短缺”成为本轮涨价的核心推手。
SSIM (Structural Similarity Index Measure) compares two images by evaluating luminance, contrast, and structural patterns across local windows. It returns a score from -1 to 1: 1.0 means the images are pixel-identical, 0 means no structural correlation, and negative values mean the images are anti-correlated (less alike than random noise). For glyph comparison, it answers the question: do these two rendered characters share the same visual structure?，这一点在雷电模拟器官方版本下载中也有详细论述
