Now you might remember my
old exclusive in which I revealed that we can't expect a flagship GPU from AMD until 2020. I also talked about how Vega was designed specifically for Apple and Navi has been designed specifically for the Sony PS5 and the question that I immediately thought was whether this is the GPU that we can expect to see featured – the answer – nope. The Navi 12 is not going to be the GPU that gets featured in PS5, its a derivative of the actual Navi die and has been created specifically so AMD can get it to market for the PC audience primarily.
I have also been told that Navi will be a new microarchitecture (in other words the first AMD Radeon uArch to not be based on GCN). This is going to be the same IP that powers the succeeding Navi dies (such as the Navi 10 and Navi 20). Now I do know that the Navi 12 GPU will have 40 CUs, what I do not know is if they are going to have the same number of stream processors as GCN does – in which case the core count is going to be 2560 sps. That does seem likely to be the case because from what I have heard the card slots in somewhere around the Vega 56 depending on the clock rate but much cheaper!
