2022 is going to be a deep year in terms of hardware changes, we will not only see new CPU and GPU architectures, which is the usual trend, but also the adoption of new types of memory and I / O interfaces, this forces both AMD and Intel to make profound changes to processor architectures. Either pure CPUs or SoCs in which they share space with an integrated GPU.
Rembrandt, the architecture of the AMD Ryzen 6000 Mobile
AMD Ryzen 6000 Mobile is not expected until the year 2022, with its corresponding official presentation at CES that same year, as has happened in the case of its predecessors. But, for the moment, we already have some data on Rembrandt architecture, which are powerfully striking.
The first one is that AMD Rembrandt will not use TSMC’s 7nm node, but 6nm. An optimized version of this that allows 18% higher logical density. It would be the second AMD SoC that according to rumors would use this node to be manufactured, the other being that of a possible revision of the PlayStation 5 console.
The second change would be in the use of the GPU and that is that AMD would finally abandon the AMD Vega architecture completely in the Ryzen SoCs. Which has been using with gradual improvements since the first Ryzen SoCs with integrated GPU. Rumors speak of RDNA 2 and a configuration of 12 Compute Units. So in 2022 we will see the first GPUs integrated with AMD’s RDNA architecture.
The third change comes from the use of the Zen architecture 3+We know very little about this processor except that it is a version for the Zen 3 TSMC 6nm node with slight performance improvements. There is talk that AMD could include the CVML unit, whose acronym stands for Computer Vision and Machine Learning. An accelerator very similar to the Intel GNA for artificial intelligence algorithms.
Warhol has disappeared from the map
To the rumors of Rembrandt making use of the 6 nm node and adopting the Zen 3+ core must be added those who say that Warhol couldn’t see the light. How do we know? Due to the fact that the latest rumors state that the only design that would make use of the TSMC 6nm node for PC by AMD would be Rembrandt.
Warhol is a huge unknown, it is supposed to be based on Zen 3+ based CCD chiplets built under the 6nm node. But at the same time we do not know what its IOD is. Since no AMD needs to build a new one to support DDR5, LPDDR5 and PCI Express 5.0. But it could also be that it will use the IOD of the current Ryzen 3000 and Ryzen 5000 for the third time and therefore support only DDR4, LPDDR4 and PCI Express 4.0 interface memory.
We’re not going to have AM5 socket motherboards until the arrival of Zen 4 and this is key to AMD’s support for DDR5, LPDDR5 and PCI Express 5.0. So logically Warhol would be a minor update like the Ryzen 2000s were. Which AMD could have removed from the roadmap to focus on Zen 4, also known as its codename: Raphael.
