VerifiedHBM achieves high-density interlayer interconnection by vertically stacking multiple layers of DRAM chips using through-silicon via (TSV) technology, delivering memory bandwidth up to 3–5 times higher than conventional GDDR6 memory, while consuming less power and occupying a smaller package footprint.84% similarUnverifiedHBM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73% similar
