The next-gen CPUs from AMD have been confirmed to [launch on October 8](https://technosports.co.in/2020/09/09/amds-new-era-coming-zen-3-and-rdna-2-launching-in-october/) and now much expectedly the specs of it have been leaked to give us some insights about the performance these CPUs. Based on TSMC’s 7nm+ EUV process, the Zen 3 architecture is said to be a much-improved one than Zen 2, which was already a revolutionary step from AMD.

The information that has been received by [Wccftech](https://wccftech.com/amd-zen-3-ryzen-4000-vermeer-cpus-detailed-up-to-16-cores-32-threads/) is part of confidential AMD documents shared by [CyberCatPunk](https://twitter.com/CyberCatPunk). As we all know the AMD Vermeer Desktop CPUs or Ryzen 4000 based on Zen 3 microarchitecture will be known as the AMD Family 19h Model 21h B0. So, as per the document, these Vermeer CPUs will be designed to use in high-performance desktop platforms.

It will be featuring up to two CCD’s (Core/Cache Complex Dies) along with a single IOD (I/O Die). Until last-gen, a single CCD comprised of two CCX’s (Core Complexes), however, in the case of Zen 3 CCD, it will consist a single CCX that will feature up to 8 cores running either in a single-thread mode (1T) or a two-thread model (2T) for up to 16 threads per CCX.

A chip will have a maximum of two CCDs, so the core and thread count will be maxed out to 16 cores and 32 threads only, same as the existing flagship Ryzen 9 3950X desktop CPU. Each of these Zen 3 cores will feature 512 KB of L2 cache to make a total of 4 MB of L2 cache per CCD and apart from it, each of the CCD will also comprise up to 32 MB of shared L3 cache. All of these Zen 3 cores can share a larger amount of L3 cache.

AMD will be introducing a slightly improved scalable data fabric with Zen 3 cores with support up to 512 GB per DRAM channel or up to 1 TB of ECC DRAM. For the memory interface, these Ryzen 4000 Vermeer desktop CPUs will still have DDR4-3200 speeds. However, there will be 2 unified memory controllers on the CPU, and each of them will be supporting one DRAM channel for a total of 2 DIMMs per channel. You can check all of the leaked specs from [Wccftech](https://wccftech.com/amd-zen-3-ryzen-4000-vermeer-cpus-detailed-up-to-16-cores-32-threads/).

Also, as per rumors, the Zen 3 architecture will bring almost 15-17% IPC uplift than last-gen which is incredible considering the fact that Zen 2 was already a fast one. So, this time you can expect AMD CPUs going as high as 5GHz officially to give Intel a stiff competition on the single-core frequency along with a 50% increase in Zen 3’s floating-point operations & a major cache redesign.

Ok, you won’t have to wait much longer for that as AMD will formally announce these[on October 8](https://technosports.co.in/2020/09/09/amds-new-era-coming-zen-3-and-rdna-2-launching-in-october/), and with any info about these Ryzen 4000 Vermeer CPUs, we will keep you informed.
