AMD’s Navi GPUs rumoured to lack a high-end offering

Rumours have started circulating that AMD’s upcoming Navi GPU architecture will lack a high-end offering, creating GPUs that will act as replacements for their existing Polaris-based RX 580 series. 

Navi will be based on a 7nm manufacturing process, taking advantage of the process node shrink to deliver a GPU with offers performance which is similar to an RX Vega 64 at a more mainstream price point. In short, Navi is expected to do to Vega what the RX 480 did to the R9 390X. 

Fudzilla has reported that AMD’s 7nm Vega chips will never hit the gaming market, instead focusing on a new Radeon Instinct series GPUs. Don’t expect a Radeon Vega 7nm refresh before Navi.   

If these rumours are true, AMD’s next generation of GPUs will be remarkably similar to Polaris in execution, focusing on the high-volume mainstream market and not the ultra-high-end. The consequence of this is that Nvidia will remain dominant in this space, giving the company no reason to offer decreased pricing with their next-generation of GPU hardware. 
 

AMD's Navi GPUs are rumoured to lack a high-end offering  

It is possible that AMD’s Radeon Navi GPU will deliver some form of Ray Tracing Acceleration, something which is also expected in AMD’s next-generation Geforce GPUs (RTX technology is exclusive to Volta at this time). 

Fudzilla has also reported that AMD’s Navi successor is not expected until at or around 2020, though there is some speculation that AMD’s “Next Gen” Radeon GPU architecture will be a total redesign, rather than another iteration of GCN. 

There is a possibility that AMD plans to release high-end Navi GPUs as part of a multi-die-module (MCM), potentially combining several smaller Navi GPU cores to create a larger whole, much like AMD’s EPYC and Threadripper series processors. This hypothesis is supported by AMD’s use of the term scalability when showcasing Navi on their early GPU roadmaps, though right now this is just a theory. 

If AMD plans to create multi-die GPUs, it makes sense for the company to focus on building smaller GPU modules, even so, it is unknown what problems these designs will introduce in practice, especially when it comes to inter-module latency.
