SK hynix Starts Mass-Production of HBM2E High-Speed DRAM

SK hynix announced that it has started the full-scale mass-production of high-speed DRAM, 'HBM2E', only ten months after the Company announced the development of the new product in August last year. SK hynix's HBM2E supports over 460 GB (Gigabyte) per second with 1,024 I/Os (Inputs/Outputs) based on the 3.6 Gbps (gigabits-per-second) speed performance per pin. It is the fastest DRAM solution in the industry, being able to transmit 124 FHD (full-HD) movies (3.7 GB each) per second. The density is 16 GB by vertically stacking eight 16 Gb chips through TSV (Through Silicon Via) technology, and it is more than doubled from the previous generation (HBM2).

HBM2E boasts high-speed, high-capacity, and low-power characteristics; it is an optimal memory solution for the next-generation AI (Artificial Intelligence) systems including Deep Learning Accelerator and High-Performance Computing, which all require high-level computing performance. Furthermore, it is expected to be applied to the Exascale supercomputer - a high-performance computing system which can perform calculations a quintillion times per second - that will lead the research of next-generation basic and applied science, such as climate changes, bio-medics, and space exploration.
"SK hynix has been in the forefront of technology innovation that contributes to human civilization with achievements including the world's first development of HBM products," said Jonghoon Oh, Executive Vice President and Chief Marketing Officer (CMO) at SK hynix. "With the full-scale mass-production of HBM2E, we will continue to strengthen our presence in the premium memory market and lead the fourth industrial revolution."

■ HBM (High Bandwidth Memory)
  • High performance, high bandwidth memory products that adopt TSV technology to dramatically accelerate data processing speed over traditional DRAMs.
■ TSV (Through Silicon Via)
  • An interconnecting technology that connects the upper and lower chips through thousands of fine holes on DRAM chip.
  • Delivers data, commands, and currents through column-shaped paths that penetrate the entire silicon wafer thickness after stacking multiple DRAM chips on the buffer chip.
  • Up to 30% decrease in size and up to 50% decrease in power consumption over existing packaging methods.
■ Standards for data process speed conversion
  • 1 GB = 8Gb
  • 3.6 Gbps per pin with 1024 data I/Os (Inputs/Outputs) = 3686.4 Gbps
  • 3686.4 Gbps / 8 = 460.8 GB/s (Gb -> GB conversion)

Can't we have like products like the NUC with HBM integrated memory say 16gb, or is the latency too high.

If you want HBM2E in consumer tech it is up to AMD to deliver NOT Intel, AMD is the only company between the two that see advantages in pushing main stream consumer tech to the limit and are willing to sacrifice a part of their profit to do it.

Intel has the policy to milk old tech to the absolute limit. If they do not have any competition in a certain tech segment they DO NOT innovate, ONLY make as small incremental upgrades for as long as possible to milk the tech to infinity. This way they make as much money as possible of of the same old tech over and over again.

So no, you won't see HBM2E in NUC from Intel before AMD makes a competing NUC alike product with HBM2E, THEN Intel will do it after maybe two years BUT only IF it cuts in to their NUC sales.
