Up until now, HBM has been confined to the upper end of the PC market. In theory, it could come farther down the stack with 7nm, but I don't think we're going to see HBM in mainstream consumer cards in the 7nm generation. HBM-based cards are trickier to manufacture because routing thousands of wires through multiple layers of DRAM is a non-trivial process. Even AMD always acknowledged that HBM only gave them an economic and power consumption boost at a specific point in their own board stack. Below a certain RAM loadout and TDP, GDDR5 made more sense, even for Team Red. With GDDR6 having repla
Samsung Flashbolt HBM2 Is 33 Percent Faster, Doubles Capacity… HBM-equipped GPUs could offer significantly more memory bandwidth at lower power consumption. But unlike typical RAM cycles, in which a new technology debuts on a limited number of cards and then waterfalls into the larger market, HBM and HBM2 have both remained at the very top of the stack. …
… We haven't seen HBM deployed for CPUs much, Hades Canyon notwithstanding, but multiple high-end GPUs from Nvidia and AMD have tapped HBM/HBM2 as primary memory. …
… Samsung is generally offering more tools, ecosystem options, and capabilities like 2.5D interposers for HBM and reference design flows. …
