A new rumour online is purporting that AMD’s upcoming Navi GPU may be based on the GDDR6 format, instead of the current HBM2 format. Additionally, it will also run on a 256-bit memory interface, as well as an 8-phase VRM.
Adding oil to the proverbial fire are images of an AMD printed circuit board (PCB), which have also leaked online. Based on the observation of one source, the eight DRAM chips surrounding the main GPU have a ball grid array (BGA) package size of 180. Which is more or less the same as the GDDR6 memory currently employed by NVIDIA’s GeForce RTX series GPUs.
Unfortunately, the leaked PCB images don’t come with any additional details. It also doesn’t help that AMD has been keeping all information about the GPU very close to its chest. So far, all we know about the GPU is that it will be based on a 7nm die lithography, and that it will also support ray-tracing in some form or another.

Thus, given its unconfirmed nature and AMD’s silence on anything relating to its next generation GPU architecture, it’s best to treat this as hearsay. Hopefully, AMD could just end up talking more about the technology at its Computex keynote this May.
