SK Hynix has added HBM2 to their product catalog


Earlier this month SK Hynix secretly added HBM2 to their product catalog, with availability for 4GB memory stacks in Q3 2016. This means that mass production has started or that it is imminent. 

First, the company will release two different versions of their HBM2 memory, both of which will come in 4GB stacks and with different data rates and bandwidth specifications. Below are the specifications of these two HBM2 stacks, the fastest of which offers as much bandwidth as the Nvidia GTX 1070 in a single chip.

To put this into perspective, if the fastest of these new memory chips were used in AMD's R9 Fury X instead of HBM1 it would have 16GB of VRAM and over 1TB/s of memory bandwidth. This kind of performance simply outcompetes all competing memory solutions in terms of memory bandwidth per chip and memory capacity per chip.

In the future 2GB and 8GB HBM memory stacks will be released as well as a slower 128GB/s variant. It is expected that no future products will be made using the companies HBM1 technology, instead moving to the faster and more storage dense HBM2 standard.

Wonder if Vega or Volta(it's still volta right?) will use a config of 4 for a total of 16GB or if they will use different variations depending on price bracket, like 2 stacks for 8GB.

What i find most impressive though, is that HBM2 not only can hit 1TB/s but do this at an even lower power consumption than HBM1 while at the same time, provide more capacity. That's a pretty big step up for a second evolution and basically destroys anything G5X can do, but obviously you pay for those benefits.Quote
