SK Hynix Kicks Off HBM3 Mass Production, Ships to Nvidia

SK Hynix was the first memory vendor to start talking about HBM3 and was the first company complete development of memory under that spec. Today the company said that it had begun to mass produce HBM3 memory and these DRAMs will be used by Nvidia for its H100 compute GPUs and DGX H100 systems that will ship in the third quarter.  

SK Hynix's HBM 3 known good stack dies (KGSDs) offer peak memory bandwidth of 819 GB/s, which means that they support data transfer rates of up to 6400 GT/s. As for capacity, each stack packs eight 2GB DRAM devices for a total of 16GB per package. SK Hynix also has 12-Hi 24GB KGSDs, but since Nvidia seems to be the company's primary customer for HBM3, the company kicks off production with 8-Hi stacks.  

"We aim to become a solution provider that deeply understands and addresses our customers’ needs through continuous open collaboration," said Kevin (Jongwon) Noh, president and chief marketing officer at SK Hynix.

    Will we see HBM in consumer GPUs again? Or is it just too expensive? The AMD cards used it that generation.
