Zen 4 CPU and RDNA2 GPU: These are the architectures to which AMD is working
AMD’s new CPU and GPU roadmaps confirm that the Zen 3 CPU design is complete while the next-generation Zen 4 architecture is at work. Great expectations also for RDNA2, the new architecture for Radeon GPU.
New roadmaps for the CPU and AMD GPU that appeared online yesterday, published by the Guru3D website, bring out confirmations of the direction the US company is working towards for the development of its future products.
Let’s start with the CPU world, which currently has the Ryzen and EPYC products based on Zen 2 architecture built with 7-nanometer production technology. These proposals will be followed by models based on Zen 3 architecture, built with 7nm+ production technology that is the evolution of the 7 nanometer one now in use. For these solutions, architecture-level design has been completed, so it is not difficult to think of seeing its commercial debut in 2020.
Below we will find the proposals based on Zen architecture 4, for which the design phase in which they are currently located is indicated. AMD has certainly already chosen which production technology will be used for products based on this architecture but for the moment, this information is not reported in the roadmap.
It is possible that it is the 5 nanometer one but a lot will depend on its availability in the period of time in which these products will debut on the market. It will take no less than 2 years to get the first CPU with Zen 4 architecture, but it is possible as indicated in the roadmap that these arrive in 2022 precisely because of the availability of 5 nanometer production in adequate volumes.
Moving on to the world of GPU, we find a similar dynamic, with the RDNA architecture being used for the Navi family GPU now on the market, always built with 7-nanometer production technology.
Next we will find the RDNA 2, based on a 7nm+ production process with a debut planned for the year 2020: few details except that it is an architecture at the moment in the design phase for which some of the architectural choices must still to be completed.
No striking news from these two updated roadmaps, if not the confirmation that AMD is working to continue the development of its products on an annual basis, making available new developments proposals of what is now on the market.
