Multiple reports from Chinese media have indicated that AMD is all set to introduce its next-gen Ryzen 4000 'Zen 3' Desktop CPUs and Radeon RX 'RDNA 2' GPUs in early Q4 2020. This will mean that we are likely to get both CPU/GPU families by October 2020, something that our sources had also pointed out back in March.

AMD Ryzen 4000 ‘Zen 3 Vermeer’ Desktop CPU And Radeon RX Big Navi ‘RDNA 2’ Graphics Cards Coming in October 2020

The latest on AMD's next-gen Ryzen 4000 'Vermeer' CPU & Radeon RX Navi 2X 'RDNA 2' GPUs in terms of launch info comes from ChinaTimes. The tech outlet reports that AMD plans to introduce its latest CPU/GPU products in the first quarter of Q4 2020. This would suggest an early October launch but once again, we aren't 100% sure if this is a hard launch or an announcement for AMD's next-generation portfolio.

What I believe could happen is that AMD will have a keynote during Computex which is scheduled for the end of September between 28th and 30th. AMD could use Computex 2020 as a platform to introduce its new Ryzen CPU and Radeon RX GPU families while announcing that the products will hit the retail market in the coming month of October.

As for the competition, both Intel and NVIDIA also have products positioned to go against AMD in the second half of 2020. AMD's Ryzen 4000 CPUs will be competing against Intel's Rocket Lake 11th Gen CPUs. That's Zen 3 on 7nm going against Intel's next-gen Cove architecture on 14nm. With new architectures onboard both CPU families, we are expected to see a good battle in the mainstream CPU segment.

AMD's Radeon RX graphics cards based on the RDNA 2 architecture are expected to tackle NVIDIA's Ampere based GeForce RTX 30 series graphics cards. These graphics cards are designed from the ground up with new GPU architectures and focus on the high-performance segment first. NVIDIA may have a first go with its Ampere based GeForce RTX 30 lineup with the first leaks suggesting a big announcement in the coming months. It seems like NVIDIA could use Gamescom 2020 as the platform to introduce its next-gen graphics card family considering Turing based GeForce RTX 20 series was also unveiled back at Gamescom 2018.

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.
