JEDEC Outlines HBM-2 Specifications; More GPUs to Utilize High-Bandwidth-Memory
According to a recent report; more GPUs other than AMD’s FIJI are expected to utilize High-Bandwidth-Memory.
Yesterday, JEDEC announced an update to ‘JESD235 High Bandwidth Memory (HBM) DRAM standard’ which is essentially a brief of what users can expect from HBM-2. You can also download the JESD235 for free from JEDEC website.
JEDEC has confirmed that HBM-2 is going to be available in 2, 4, and 8 high stacks. VideoCardz notes that if either of NVIDIA or AMD decide to use even 4 stacks of with the upcoming Polaris or Pascal GPUs, we should expect to see GPUs with as much as 32 GB of video memory. However, it is needless to say that gaming graphics card with as much as 32 GB of memory capacity is clearly an overkill, but for high-end workstations, the idea does seem feasible.
Speaking of this, Barry Wagner, JEDEC HBM Task Group Chairman stated:
GPUs and CPUs continue to drive demand for more memory bandwidth and capacity, amid increasing display resolutions and the growth in computing datasets. HBM provides a compelling solution to reduce the IO power and memory footprint for our most demanding applications.
The report further reads that the cheapest version of HBM-2 is 2-Hi variant which is basically 1GB per stack which as compared to HBM-1’s 256 MB per layer is 512 MB per layer in HBM-2.
