Rumours have appeared on-line that the next-generation structure after AMD’s upcoming Navi could also be ditching GCN cores altogether. This hypothesis has additionally led to questions relating to Navi’s path, and what to anticipate from the upcoming and not-too-distant graphics card generations from the pink group.

Recent rumours have been speculating that post-Navi will see the tip of AMD’s geriatric Graphics Core Next (GCN) structure – which has been struggling considerably to scale alongside the competitors. AMD’s upcoming Navi structure will likely be constructed on a brand new iteration of the GCN structure, though doubtlessly utilising multiple GPU cores sewn along with some variant of AMD’s Infinity Fabric to counterbalance the ageing GCN design.
Tweaktown tried to achieve out for affirmation on the rumours, and whereas they obtained no clarification on the matter of the GCN structure being booted out the door, they did hear that supposedly the Navi structure growth wasn’t going too effectively, being “just as bad” as Vega, and that AMD’s RTG group have little or no path going ahead. If true, this can be a considerably anticipated symptom of ex-RTG chief Raja Koduri’s untimely departure to Intel.
According to Tweaktown’s unnamed sources, Navi will likely be a refined Vega technology and will doubtlessly be a catastrophe – as additionally they declare the Vega structure was itself. It would not be stunning to see the next-gen structure – following Navi – ditch the ageing and seemingly unscalable GCN structure. With RTG below new management, it looks as if doubtlessly the precise time to make the change, nonetheless, this all nonetheless stays unsubstantiated by AMD to date.
The structure past Navi stays unconfirmed by the pink group – solely indicated by ‘next-gen’ on roadmaps for round 2020, and that it’ll arrive on 7nm+. AMD CEO and president Lisa Su confirmed at a pre-CES occasion that AMD’s leapfrogging design groups are already onerous at work on the next-gen structure, nonetheless.
“We continue to make excellent progress on the Navi architecture, and you’ll hear more about Navi as we take that into 7nm.” Su says “And we have another development team that’s already started work on the next-gen graphics in 7nm+.”
CTO Mark Papermaster additionally reiterated Su’s feedback on the upcoming GPU architectures.
“Our Navi design is very exciting, that microarchitecture is going to bring several key improvements. And as well leap-frogging design teams into next-gen with 7nm+ and further performance per Watt enhancements”
Unfortunately, we nonetheless have little or no indication on the post-Navi technology and these rumours appear solely speculative to date. It certainly is reaching considerably the tip of the street for the GCN design, however when this foundational change will occur remains to be unknown as of but. With new management in place at RTG, present roadmaps are prone to be topic to appreciable modifications earlier than they arrive to go.
