From Guru3D it seems that AMD could present its new Vega 20 silicon during its conference at Computex 2018, which will take place on Wednesday 6th June. However, Vega 20 would not be presented for gamers, but as a solution for professionals as a refresh of Vega 10 and manufactured under the new 7nm node.
A lot has been said about Vega 20 in the past and we have even seen a benchmark in 3DMark that talked about a GPU with 32GB of HBM2 memory. In principle, the source says it would be a simple Vega 10 refresh, but other rumours from the past point to Vega 20 as an MCM design with two Vega 10 die glued together that would be the precursor of this technique before the arrival of NAVI-based GPUs.
This implies that the new silicon would have a total of 8192 Stream Processors and a memory bus probably of 4096 Bit that would double the bandwidth of the Vega 64 or its professional variants to limits close to 1TB/s, a figure that could be exceeded if the HBM2 memories arrive with increased speeds as we are seeing in the new APUs such as Fenghuang.
However the gamers maybe, we won’t see Vega 20 until 2019 and that’s if AMD doesn’t decide to jump straight to Navi for its new generation of desktop graphics cards. For now, it seems that a 12nm refresh of the RX 500 “Polaris” could be on the table, but nothing has yet been confirmed.
