A recent presentation of the AMD and SK Hynix co-developed 3D stacked High Bandwidth Memory standard HBM has made its way to the web. This new leak gives us a very good idea of what to expect from the new technology in terms of performance and market availability.
HBM Memory :
HBM was originally developed in tandem by both SK Hynix and AMD to replace GDDR5 as the new standard for bandwidth hungry processors such as GPUs. GDDR5 performance scaling has slowed down dramatically and grown exponentially more expensive in the last few years. Faster GDDR5 modules and wider memory interfaces were only going to take us so far, a new standard had to replace the aging technology.
