find Memories HBM in products available to home consumers is not an easy task, and it does not seem to be something that will change in the near future - the next generation of this device is already here, and it sounds exotic and more expensive than ever.
The updated standard for HBM2 now supports maximum speeds of up to 3.2 Gbps per pin interface between memory chips and other system components, without changing the 1,024-bit base interface that came with the second generation of technology - so for a single "tower" chip that will be integrated Together with chip Processing will be possible at speeds above 3TB, or 410GB per second.
This data becomes even more exciting when one begins to examine the possibility of combining several HBM2 enclosures on one interposer unit in parallel with the processing unit it will serve - with theoretical support for 12 layers of chips memory Fast one gigabyte of volume in any such package, the processing products of the future can come with up to 2GB of memory HBM2, At a fast speed, crazy rules of 1,640 gigabytes per second, or 1.64 terabytes per second. Most impressive, especially when you consider that the most advanced theoretical implementations of chips compete with technology GDDR6 Should approach the terabyte bandwidth in a second "only".
So when will we see the use of the updated version of the HBM2 standard? This may be closer than you'd expect, as Samsung seems to be planning to build on the technology in its HBM2E chips under the code name Flashbolt - with up to eight layers of 2GB each in the case chip Single for up to 16GB (and 64GB for four-array arrays) Enclosures Such) in a recent production process of less than 20 nm, which was used for theHBM2 Previous ones from the giant house.
Samsung is already preparing for mass production of HBM Flashbolt during the current quarter, and states that it will be able to offer these memories at an even higher speed than JEDEC defines in the standard - up to 4.2 GB per second per pin in the interface, resulting in a monstrous theoretical speed of almost 540 g 1,024 gigabyte per second for a single package at an interface of 2.15 bits, and XNUMX terabytes per second (!) For four Enclosures in parallel.
HBM2 technology can certainly knock any hardware enthusiast off the chair, but it seems that with the popularity of the cheaper and simpler GDDR6 technology to combine - we will continue to find the Flashbolt and the like mainly in ultra-luxury products designed for the HPC worlds and information centers, as part of branded models The Tesla of NVIDIA And the Radeon Instinct of AMD.
