UnverifiedHBM每单位面积的售价约为GDDR7的3到5倍，导致晶圆厂在产能分配时倾向优先满足HBM订单，造成GDDR7产能紧张76% similarUnverified据行业估算，生产1颗HBM3e所消耗的DRAM晶圆面积相当于生产约5-6条标准DDR5内存条70% similarUnverified此轮涨价核心驱动力是HBM需求暴增，AI加速卡如英伟达H100/H200大量使用HBM，三星和SK海力士将相当比例DRAM产能转向HBM生产69% similarUnverified相比传统GDDR6显存，HBM的内存带宽可高出3-5倍，同时功耗更低、封装面积更小68% similarUnverified每生产1GB的HBM所消耗的晶圆产能是生产1GB DDR或LPDDR的三倍以上66% similar
