If one company is bad at bragging, then it’s AMD. It’s two main competitors are a lot better in that – NVIDIA even bragged about their upcoming GPUs having HBM. So I was surprised that recently I encountered a nice infographic, where AMD was actually bragging. And they deserved to do it!
I wanted to have comparisons with Intel/Micron’s HBC, but I leave that for another post as the good information is often a year old.
It’s using a high-speed bus on the substrate.
And yes, it really matters to be closer to the processor.
So for maintaining 320GB/s you would need 30 Watts. Now you need 9 Watts. As the reduction in power for the Radeon NANO is almost 100W, you understand that this tells only part of the power-reductions made possible.
Yes, 94% less surface area. Only part of the reason is the stacking.
HBM has been engineered and implemented by AMD, made a standard by JEDEC and put into sylicon by Hynix.
And finally some bragging! AMD has made many standards we use daily, but never knew it was AMD technology.
