During its Financial Analyst Day, AMD presented it's latest CPU roadmaps and confirmed that the next-generation Zen 3 based Ryzen & EPYC Milan CPUs are arriving later this year. Based on a 7nm process node, the new Zen 3 based CPU families are going to deliver a huge leap in performance per watt and IPC gains.

AMD Reaffirms Zen 3 Based EPYC Milan Server & Ryzen 4000 Desktop CPUs Launch In 2020 - Zen 4 Based EPYC Genoa Expected Next Year

Once again, most of the details are something that we already knew and AMD just reaffirmed those. According to the latest roadmap, AMD will be launching its Zen 3 CPU architecture this year in two key product families, the 4th Generation Ryzen 4000 series desktop processors and the 3rd Generation EPYC Milan server processors.

AMD has listed Zen 3 as 7nm (previously referred to as 7nm+) since it caused confusion as many thought it was AMD referring to TSMC's 7nm EUV node but the company has stated that they've not unveiled the process node officially as of yet and will do so at a later date. Coming to the new roadmap, we see Zen 3 (7nm) listed as a 2020 part with Zen 4 (5nm) replacing in in 2021. Since the Zen 3 parts are shipping in late 2020, it is highly likely that Zen 4 chips would follow suit and could hit the market by end of 2021 or even early 2022.

AMD has so far confirmed themselves that Zen 3 brings a brand new CPU architecture which helps deliver significant IPC gains, faster clocks and even higher core counts than before. Some rumors have even pointed to a 17% increase in IPC and a 50% increase in Zen 3's floating-point operations along with a major cache redesign.

When asked about what kind of performance gain Milan's CPU core microarchitecture, which is known as Zen 3, will deliver relative to the Zen 2 microarchitecture that Rome relies on in terms of instructions processed per CPU clock cycle (IPC), Norrod observed that -- unlike Zen 2, which was more of an evolution of the Zen microarchitecture that powers first-gen Epyc CPUs -- Zen 3 will be based on a completely new architecture.

Norrod did qualify his remarks by pointing out that Zen 2 delivered a bigger IPC gain than what's normal for an evolutionary upgrade -- AMD has said it's about 15% on average -- since it implemented some ideas that AMD originally had for Zen but had to leave on the cutting board. However, he also asserted that Zen 3 will deliver performance gains "right in line with what you would expect from an entirely new architecture."

The AMD Ryzen 3000 CPUs based on the Zen 2 architecture have seen an incredible response by the PC industry with a total of 260+ Million Zen cores being shipped to date and the bar keeps on rising. It looks like the Zen 3 launch is going to bring even more momentum to AMD's CPU segment and the overall market share.
