During its presentation at Computex 2018, AMD revealed its first ever 7nm GPU, Radeon Vega Instinct. However, that is not the only thing that company had to reveal or say about its GPU as AMD has noted that upcoming AMD Navi GPUs might not necessarily use the HMB2 memory and these GPUs could work perfectly with GDDR6 due to the architecture being flexible enough to work with both.
Speaking with PCGamesN, David Wang, AMD’s new senior VP of engineering for the Radeon Technologies Group, and Scott Herkelman, VP of Radeon Gaming talked about the flexibility of the Navi GPU architecture.
According to AMD, while they have their eyes set on the HBM technology due it being great for “datacentre/workstation type of application” but they are also planning to introduce the GDDR6 memory to the market.
We’re also working very closely on bringing the next-generation GDDR6 to the market. I wouldn’t say HBM2 is contradicting to performance-per-dollar and performance-per-Watt, it’s just sitting in a different price segment.
When asked if this means that the high-end AMD Navi GPUs will be using the HBM2 memory while the gaming GPUs will shift towards the GDDR6 memory. To this Scott Herkelman replied that its opportunistic and they are committed to both HBM2 ad GDDR6 and wants the best thing for the consumers.
I would say it’s opportunistic. It depends on how we see our roadmap, how we would like to play it out with some of our partners, and the innovations we want to have and what we want to do in the professional space. But we are fully committed to HBM and we’re going to be fully committed to GDDR6, and let the best solution win.
However, if AMD moves towards the GDDR6 memory for its AMD Navi GPUs then it wouldn’t be surprising since the GDDR6 is very comparable to HBM2 in terms of bandwidth.
As teased by Micron, the GDDR6 GPU memory could reach up to 20Gbps of bandwidth and Micron’s GDDR6 memory overclock headroom showcases that upcoming Nvidia and AMD GPU featuring the GDRR6 memory might surpass the HBM2 bandwidth.
What is your take on the situation? Should AMD go with HBM2 or GDDR6 for its Navi GPUs? Let us know in the comments.
