AMD has officially confirmed that it is currently working on the development of Zen 5, which will be modeled and refined alongside Zen 4, with the Zen 3 design being the successor to the existing Zen 2 architecture that powers Ryzen (and Epyc) processors and Current Navi GPUs. - Already made and sprinkled.
As Wccftech noted, Mark Papermaster, AMD Technical Director and Executive Vice President, made these revelations during a speech at the Epyc Horizon Executive Summit, held there There is a week in Rome.
He said the Zen 3 design was complete, with the Zen 4 and 5 versions currently in the design phase, and that it was all part of AMD's commitment to getting back to performance. leadership and stay in the future.
Apparently, the main designs for Zen 5 and Zen 4 are developed by two separate teams of designers, with Zen 4 expected to arrive in 2022. Therefore, it is possible that Zen 5 will be vaguely considered for 2024.
The fact that the Zen architecture is retained for the fifth time demonstrates the confidence that AMD has in its design.
Zen and the art of processor maintenance
Zen 2 uses a 7nm process and has achieved impressive performance over the original Zen architecture, with a roughly 15% increase in CPI (clock instructions).
Zen 3 will grow at 7nm + (a refined 7nm process) and an increase in CPI of around 8% to 10% is rumored over Zen 2. Zen-based chips 3 (Ryzen 4000) should launch in the second half 2020, and it shouldn't require a new motherboard if you're upgrading from a Ryzen 3000 processor.
Another piece of juicy speculation that has been whispered lately is that the Ryzen 4000 will move forward in terms of simultaneous multithreading, with the possibility of having four threads per heart (instead of two currently). In other words, we could see dual-core processors with 8 threads and quad-core processors with 16 threads.
In short, it is clear that AMD wants to firmly press the gas pedal, which is not surprising if today it wins big against Intel, the rival chip giant. be forced to apply significant price drops to some of its processors (with the possibility that it is potentially the same in the portfolio).
By the way, Mark Papermaster recently blogged for us on how AMD uses chiplets in processor design to solve the inexorable slowdown in Moore's Law.
