High Bandwidth Memory (HBM) debuted with AMD's Fury series graphics cards and was quite the success, although it had some limitations. The two biggest were that it was limited to 4GB and only had a maximum bandwidth of 512 GB/s. This is going to change with HMB2 which will introduce capacities up to 32 GB and speeds of 1 TB/s. This will be more than powerful enough for next-generation graphics cards coming from both NVIDIA and AMD.
