The HBM2e memory module is specced as a 1024-bit memory, clocked at 3.6 GHz and made by SK Hynix. Per stack carries up to 16GB. This is possible via its 8 layered DRAM stack with 16Gb storage capacity each.
What’s also promising is that SK Hynix is ramping up its production volume of these memory chips. AMD used HBM 1st gen on its Radeon R9 Fury X but the lack of availability due to memory shortage put itself on the backburner. AMD is testing HBM2 on the Radeon Pro 5600M. These can scale up to 8 GB running at 1.54 Gb/s at 394 GB/s.
“SK Hynix has been in the forefront of technology innovation that contributes to human civilization with achievements including the world’s first development of HBM products,” said Jonghoon Oh, Executive VP and Chief Marketing Officer (CMO) at SK Hynix. “With the full-scale mass-production of HBM2E, we will continue to strengthen our presence in the premium memory market and lead the fourth industrial revolution.”
While many would favour the conventional GDDR, eventually everybody will have to move on. Graphics-intensive workloads will increase exponentially, making the need to have faster and larger memory to keep up the pace. We should see these being used mostly for notebooks and even in mini PCs. The other benefit of HBM type memory is the ability to save PCB footprint. This will enable manufacturers to make high-performance GPUs with a smaller footprint.
Soon, these will be used in graphics card lineups. Nvidia Ampere is expected to use either the GDDR6 or the HBM2e.
