HBM is fundamentally manufactured using DRAM processes, and producing HBM per unit wafer consumes more wafer area; every additional HBM unit produced reduces the available capacity for standard DDR5 memory.

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.76% similarUnverifiedWhen AI data centers buy large quantities of HBM, fabs shift capacity toward higher-margin HBM, indirectly squeezing consumer-grade memory supply.74% similarVerifiedCompared to conventional GDDR6 memory, HBM can deliver 3–5 times higher memory bandwidth while consuming less power and occupying a smaller package footprint.71% similarUnverifiedThe latest generation of HBM3E can include 8 to 12 DRAM die per stack, providing over 1 TB/s of bandwidth, which is more than 20 times the bandwidth of conventional DDR5 memory (50–60 GB/s).70% similar
