New leak: AMD Ryzen 6000H Rembrandt laptop APUs with 6 nm Zen 3 + RDNA2 cores to support LPDDR5-6400 RAM and dual USB4 connectors, could launch in late 2021

AMD's leaked roadmap now shows that the Rembrandt APUs would come in desktop as well as laptop versions with 6 nm Zen 3 cores and RDNA2 iGPUs, plus support for DDR5-5200 / LPDDR5-6400 RAM, a mysterious CVML (computer vision & machine learning) component, 20x PCIe 4 lanes and two USB4 connectors.

AMD impressed everyone with the Renoir laptop APUs launched this year, and it looks like Intel is starting to lose market shares on the mobility side, as well, in addition to the difficulties emerging in the desktop market. Yes, Intel’s Tiger Lake laptop CPUs are marginally better than Renoir now, but team red is already planning to release new mobile APUs codenamed Cezanne with Zen 3 cores later this year (possibly together with the Zen 3 desktop CPUs) or early next year at the latest. From the leaked roadmaps we have seen in the past months, it looks like AMD intends to increase the rate at which it releases new versions and we could be seeing the Cezanne successor codenamed Rembrandt launched before the end of 2021.

Cezanne will be considered as a small upgrade over the existing Renoir APUs, since it only replaces the Zen 2 cores with the Zen 3 cores, leaving everything else intact, including the Vega iGPU and the LPDDR4 support. The real upgrade will be coming with the Rembrandt models that will most likely require a totally new platform. Twitter users MebiuW and Patrick Schur recently updated the roadmaps with new info regarding the Rembrandt APUs, and the new specs really paint an enticing picture.

We already knew that Rembrandt would finally combine the Zen 3 cores with the RDNA2 iGPUs, but other specs were quite iffy. The new leaks claim that Rembrandt would launch as the Ryzen 6000G and 6000H series (both laptop and desktop versions, just like all the previous APU families) with TDPs between 45 W and 65 W. The Zen 3 cores will receive a small upgrade due to being fabricated on the intermediary 6 nm nodes from TSMC, and the new platform will receive PCIe 4 support, together with DDR5-5200 / LPDDR5-6400 RAM support and a CVML (computer vision & machine learning) component.

AMD will continue to provide 20x PCIe lanes for the laptop APU versions (PCIe 4.0 this time, as previously mentioned), but the more intriguing Rembrandt upgrade is the addition of two USB4 (40 Gbps) ports, a much needed feature that has been Intel-only for quite some time now. This should allow AMD fans to pair more powerful external dGPUs with their laptops.

The partial roadmap also shows 5 nm Zen 4 Raphael CPUs and Dragon Crest APUs launching by 2022.

I first stepped into the wondrous IT&C world when I was around seven years old. I was instantly fascinated by computerized graphics, whether they were from games or 3D applications like 3D Max. I'm also an avid reader of science fiction, an astrophysics aficionado, and a crypto geek. I started writing PC-related articles for Softpedia and a few blogs back in 2006. I joined the Notebookcheck team in the summer of 2017 and am currently a senior tech writer mostly covering processor, GPU, and laptop news.
