Now the details that are mentioned are broken into two parts, one is for the initial AMD Navi cards that utilize the Navi 10 GPU architecture and the second is for the high-end, enthusiast grade parts that would feature the Navi 20 GPU. According to RedGamingTech, the details were acquired from sources who have been very accurate in the past as per their claim.
The details say that before
Raja Koduri, AMD’s ex-head of Radeon Technologies Group, left the company, one of his major tasks was to fix many of the weaknesses in the GCN architecture. The reason to do this was to let AMD RTG focus on both, producing a next-gen architecture while working on GCN iterations to remain competitive against NVIDIA GeForce and Quadro lineups. Now we have seen that this strategy worked well for AMD in the mainstream market but their flagship products weren’t necessarily the best or to make it simple, king of the hill products that AMD wanted them to be but rather side options to NVIDIA’s enthusiast offerings.
The reason why Vega didn’t live up to the hype was that when Raja joined RTG, the
design of the Vega GPU was very much completed and there was little he could do. The actual goal for Raja was to work on Navi GPUs which would still be based on the existing GCN architecture but further refined through fixes to let’s say, the geometry engine, as reported by RedGamingTech. Now it is possible and very likely that AMD had finished the design for Navi much before Raja left RTG. But what happens to Navi when it goes into the development phase, that’s something we are really close to finding out now as rumors are alleging a launch of the first Navi based Radeon RX cards in mid of 2019.
