According to the details of HBM disclosed, HBM is a weakened version of 3DS.
Like 3DS, HBM is a three-dimensional memory, which is the biggest difference between motherboard and traditional memory. The traditional memory is flat, and the memory particles are tiled. Moreover, due to the limitation of technology, it is difficult to increase the frequency of planar DDR5, so its life is limited in the case of large tasks.
