While we already heard a lot about the second generation High Bandwidth Memory, JEDEC has now announced the official specification of the HBM2.

High Bandwidth Memory (HBM) was first introduced with AMD Fury series graphics cards and brought some improvements but also had limits with 4GB capacity and maximum bandwidth of 512GB/s. JEDEC Solid State Technology Association has now released the official specification on the second generation High Bandwidth Memory (HBM2) which brings memory capacity of 32GB and maximum bandwidth of 1TB/s.

This means that the HBM2 will double the bandwidth offered by HBM and while it will bring improved performance, it also reduces power consumption by 8 percent.

Nvidia already announced that it will be using HBM2 on its upcoming Pascal GPU based graphics cards, with 16GB at 1TB/s and probably even 32GB in near future.

AMD has also confirmed that its next generation Polaris GPU based graphics cards will also use the same memory and it will certainly be interesting to see what is the actual real world performance gain compared to GDDR5 and the first generation HBM.
