The last few weeks have only been about Intel and Nvidia. We heard continuous praises about how good the new RTX 3000 series is and how much performance and value it brings. However, AMD in addition to their newer graphics cards also has plans for the next-generation Zen 3 Ryzen CPUs and they are BIG. CyberCatPunk shared some of these new plans with Wccftech and here is what we know.

A good GPU is only half of the story. While a good GPU can transform your gaming experience a good processor is just as important. Imagine pairing an RTX 3080 with an older CPU you will experience serious bottlenecks. In addition to a relatively newer CPU now users also have to make sure that their CPU supports all the new features required by the GPU. AMD has been at Intel’s throats for a while now, the Ryzen series right from its launch has ruled the budget kingdom and that is not going away.

We now have specifications of the Next-Gen Ryzen 4000 CPUs. The information comes from confidential AMD documents on the new AMD processors using  Zen 3 core architecture. We now know that the new Ryzen processor based on the Zen 3 architecture will launch on October 8th. The new processors use TSMC’s7nm+ EUV process. According to current information, Zen 3 architecture brings considerable improvements to the table as compared to Zen 2.


The leaked documents provide some key points on the upcoming Vermeer CPUs. AMD calls the Vermeer Desktop CPU family as the AMD Family 19h Model 21h B0. This specific lineup is built for high-performance desktop platforms according to AMD.

The Ryzen 4000 CPUs will feature up to two CCD’s (Core/Cache Complex Dies) and a single IOD (I/O Die). The CCD design has changed this time around for Zen 3 and the Zen 3 CCD will contain a single CCX that will feature 8 cores that can run in either a single-thread mode (1T) or a two-thread model (2T) for up to 16 threads per CCX. Previously, Zen 2 had two CCX’s per CCD.

Zen 3 CPU Specs:

In addition, the Zen 3 Ryzen 4000 CPU chips come with support for a maximum of two CCDs. Which results in the core and thread count maxing out at 16 cores and 32 threads. Interestingly, the max core/thread seems to be the same as the last-gen Ryzen 3000 series CPUs.

However, in the newer CPUs, every core will have 512 KB of L2 cache for a total of 4 MB of L2 cache per CCD. This results in 8 MB of L2 cache on a dual CCD CPU. Also, the shared L3 cache will also be up to 32mb per CCD. In conclusion, the size of the cache from Zen 2 remains the same per CCD. But now all cores can share a larger number of L3 cache.

Adding to that, with the Ryzen 4000 desktop CPUs also comes a slightly improved scalable data fabric. This is the essential data path that connects the compute complexes, the I/O interfaces, and the memory interfaces to each other. Consequently, the Ryzen Vermeer CPUs support up to 512 GB per DRAM channel or up to 1 TB of ECC DRAM. However, Ryzen 4000 Desktop CPUs will retain the native DDR4-3200 speeds.

Lastly, we have already heard from AMD that Zen 3 brings a brand-new CPU architecture. This delivers significant IPC gains, faster clocks, and even higher core counts than before. Some rumors hint of up to a17% increase in IPC and a 50% increase in Zen 3’s floating-point operations along with a major cache redesign.

Now, If you plan to get yourself one of these new processors you won’t have to wait that long as the release date is just around the corner. Stay tuned to our website for benchmarks once these new processors drop.
