AMD Ryzen 4000 ‘Vermeer’ Desktop CPUs With Zen 3 Cores Going in Mass Production Soon, Already in B0 Stepping – Wccftech

AMD Ryzen 4000 CPUs are one of the most anticipated launch of this year when it comes to latest processors. Featuring the Zen 3 cores which are expected to deliver incremental IPC gains & brand new architectural changes, the Ryzen 4000 Desktop CPUs will be the 3rd most significant launch in the Ryzen family of CPUs that has been introduced since 2017.

AMD Ryzen 4000 ‘Vermeer’ Desktop CPUs Hitting Mass Production Soon, B0 Stepping With Zen 3 Cores Ready

I say 3rd significant launch in the Ryzen family because we all know that Zen+ which came after the original Zen core was more of a refresh on a slightly enhanced node. The Zen+ architecture did go on to deliver some key efficiency and clock gains over the Zen 1 based Ryzen 1000 CPUs but so far, there have been two major launches for the desktop family, the 14nm Zen 1 and the 7nm Zen 2.

The 3rd major launch will be in the form of the 7nm+ based Zen 3 powered Ryzen 4000 CPUs that are codenamed ‘Vermeer’ for the desktop platform. In a series of leaks, Igor’s Lab has confirmed that Ryzen 4000 Desktop CPUs are already in B0 stepping and will be heading to mass production soon. Since we’re already in Q3, a mass production around the mid of this quarter would suggest a hard launch in Q4 which is something that has been pointed out for a while now.

According to the source, the B0 stepping is close to the final retail version so it should not be long before mass production commences on AMD’s Ryzen 4000 ‘Vermeer’ Desktop CPUs. Only time will tell if AMD can produce enough CPU quantities to carter a hard launch during the holiday season that is Q4. There have been rumors going around for a while that AMD’s initial Ryzen 4000 desktop CPUs would be aiming the high-end segment first following up with mainstream and entry-level chips for the mass volume market in early 2021.

Back in 2019, AMD had to face some trouble with its high-end Ryzen 3000 supply consisting of Ryzen 7 and Ryzen 9 CPUs which were available in very limited quantities around the globe that was mostly due to the fact that TSMC’s entire 7nm capacity was fully booked by other customers but AMD being one of the leading and largest customers of 7nm had a fair bit of supply open up for them to ease up the huge demand of its high-end CPUs.

Here’s Everything We Know About The Zen 3 Based Ryzen 4000 ‘Vermeer’ Desktop CPUs

The AMD Zen 3 architecture is said to be the greatest CPU design since the original Zen. It is a chip that has been completely revamped from the group up and focuses on three key features of which include significant IPC gains, faster clocks, and higher efficiency.

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.”

Other rumors have pointed out to a 50% increase in overall floating-point performance. We also got to see a major change to the cache design in an EPYC presentation, which showed that Zen 3 would be offering a unified cache design which should essentially double the cache that each Zen 3 core could have access compared to Zen 2.

The CPUs are also expected to get up to 200-300 MHz clock boost, which should bring Zen 3 based Ryzen processors close to the 9th Generation Intel Core offerings. That, along with the massive IPC increase and general changes to the architecture, would result in much faster performance than existing Ryzen 3000 processors, which already made a huge jump over Ryzen 2000 and Ryzen 1000 processors while being an evolutionary product rather than revolutionary, as AMD unveiled very recently.

The key thing to consider is that we will get to see the return of the chiplet architecture and AMD will retain support on the existing AM4 socket. The AM4 socket was to last until 2020 so it is likely that the Zen 3 based Ryzen 4000 CPUs would be the last family to utilize the socket before AMD goes to AM5 which would be designed around the future technologies such as DDR5 and USB 4.0. AMD’s X670 chipset was also hinted as to arrive by the end of this year and will feature enhanced PCIe Gen 4.0 support and increased I/O in the form of more M.2, SATA, and USB 3.2 ports.

It was recently confirmed by AMD that Ryzen 4000 Desktop CPUs will only be supported by 400 & 500-series chipsets while 300-series support would be left out.

As for competition, the AMD Ryzen 4000 ‘Zen 3 Vermeer’ lineup would compete against Intel’s soon to be released Comet Lake-S and its upcoming Rocket Lake-S desktop processors. Tackling the Intel Comet Lake-S won’t be so hard since the Ryzen 3000 CPUs are competitively positioned against the entire lineup as evident from the recent performance leaks, but Rocket Lake-S seems to be a major architectural uplift for Intel (although still based on 14nm process) which might just be Intel’s way back in the desktop mainstream market.

With that said, Rocket Lake-S is still something that needs to be evaluated prior to its release before we can call it a Zen 3 challenger but time would make it clear. As for now, the competitive advantage that AMD has with its Zen 2 based Ryzen 3000 is just way too big compared to whatever Intel has in their sleeves for this year and Zen 3 based Ryzen 4000 processors are going to push that envelope even further.
