AMD promises Zen 4 again with a significant increase in performance per beat

January 13, 2021

AMD has previously confirmed that the Zen 4 processor architecture will be based on the 5nm manufacturing process, and although there are some doubts as to whether there will be a 7nm refresh of this architecture after Zen 3, the information provided by AMD on the virtual CES 2021 does not suggest this. .

AMD speaks of Zen 4 as the next next generation of generators, and we can expect this at the beginning of next year, according to the usual delays between old and new processors. At that time, TSMC will have a significantly increased capacity of 5nm lines according to the plan, which at that time should have at least the same capacity as the 7nm process in the first half of 2020. And then AMD had long ago had 7nm products on the market of its first generation , so there should be no major problem with the production process and its capacity.
Rick Bergman got a question regarding what we can expect from the Zen 4 microarchitecture in terms of performance per clock cycle (IPC), ie regardless of a possible increase in the number of cores or clock cycles. In response, Bergman recalled that the Zen 3 offers about a 19% increase in performance per clock compared to the Zen 2, which is the result of a “long list of improvements.”

According to Bergman, Zen 4 will have a similarly long list of improvements, which will concern, for example, the configuration of cache memories, branch prediction or execution pipelines. In short, there will also be a lot of changes aimed at increasing performance, while the production process will be primarily a way to achieve higher power per watt, which AMD will definitely also use.

This actually confirms to us that Zen 4 will not just be about moving to a new manufacturing process and that AMD will not really take advantage of Intel’s original Tick-Tock strategy, which alternates between new processes and significant changes in architecture. After all, AMD has stated before that it wants to regularly increase the performance of its processors.

We can look forward to once again more powerful Zen 4 processors, which will also use a brand new platform with a new socket and support for DDR5 memory and perhaps also the PCIe 5.0 bus.
