The roadmaps of different companies change for strategic reasons and many times products which were intended to be launched on the market and which had been disclosed to different insiders are withdrawn, other times they are the product of misunderstandings and misunderstandings. confusion that ends up making the ball bigger. One of those cases is Zen 3+ cores, let’s see what happened to them.
The origin of the AMD Zen 3+ kernel rumor
A few years ago, AMD released a variant under the GLOBALFOUNDRIES 12nm node of the first Zen, which appeared under the Ryzen 2000 series and with the name of Zen +. Architecturally, this wasn’t a change from the 14nm version of the chip, but Lisa Su had simply moved her Zen core to a more advanced, but compatible, derivative manufacturing node.
This is the same case as the TSMC 6nm node, a more advanced version of the 7nm node that supports the same designs. This was exploited by AMD for the next generation of its APUs under the code name Rembrandt. This led to speculation on a Zen 3+ core under the 6nm node, which we were supposed to see both as a new CCD chip for a supposed new AMD Ryzen 6000 named Warhol, and to Rembrandt.
For some time now, rumors of a Zen 3+ kernel Se han ido from shinchandoRembrandt’s new features are more in other sections outside of the CPU such as using RDNA 2 as an integrated GPU and support for DDR5 and LPDDR5. We can say that if AMD made the change of CPU in its last generation APUs, in the next generation it will do everything except the CPU. As for Warhol, he just tabled the roadmap a long time ago.
We’ve seen Zen 3+ before and many haven’t noticed
We have no doubt that the Zen 3D kernel that Lisa Su presented a few months ago at a conference is undoubtedly AMD’s bet to improve the performance of its Zen 3 kernels and would therefore occupy the space of the supposed Zen 3+. Zen 3D technology based on the use of V-Cache does not require the construction of a 6nm version of Zen 3, since the 7nm model was already designed to place the V-Cache there. For what there would be no such CCD chip under TSMC 6nm node Rumors have said, but there would be versions of the current Zen 3 with the V-Cache mounted on top.
It is said that the performance improvement thanks to V-Cache is 15% and that may become a good answer to Intel’s Alder Lake. In any case and for marketing reasons it makes a lot more sense Zen 3D name than Zen 3+because it further defines its technology. At the moment, rumors suggest that we will not see a Ryzen 6000 range based on Zen 3D and that the nomenclature of Zen 3 models with V-Cache will be in the Ryzen 5000 series, but with the 3D designation at the end of their name. For example, the Ryzen 7 5800X with V-Cache could be renamed Ryzen 7 5800X-3D, although this is all still a rumor.
In any case it would depend on the launch time of the CPUs based on Zen 4, it does not make sense for AMD to launch these processors on the market to launch those based on Zen 4 in the coming months. It is also possible that the two CPUs share space in the 2022 wallet. Either way, in a few weeks or months we will have doubts.
