Leaker @ Broly_X1 released a roadmap on Friday listing AMD's mobile plans through 2022. The roadmap confirms and adds context to several leaks and rumors. This shows that AMD is working on an update to Zen 3+ for phones, which is expected to be released in 2022.
The two green sections of the road map are important. Rembrandt is the code name for the temporary Ryzen 6000 mobile chips. We don't know if this is the name AMD will end up with, but it's a good guess like any other. The roadmap shows that these mobile chips are based on the 6 nm Zen 3+ architecture, which is a revision of the currently available 7 nm Zen 3 architecture.
Assuming AMD continues to partner with semiconductor maker TSMC, these chips will have modest improvements over their Zen 3 counterparts. The 7nm process and the 6nm process are closely related at TSMC, with the latter showing minor improvements. Basically, Rembrandt is not a completely new generation of processors.
The mobile chips will also contain RDNA 2 graphics cores. The current Ryzen 5000 mobile chips from AMD continue to use the older Vega graphics cores, so Rembrandt gaming laptops will give a significant boost. Like the RDNA 2-based RX 6000 graphics cards, these cores could offer a hardware-accelerated ray tracing function. Rumor has it that they can boost graphics performance by up to 50%.
Rembrandt U chips are aimed at thin and light laptops with only 15 watts of power, while Rembrandt H chips for dedicated gaming laptops can deliver up to 45 watts. Both chips will support PCIe 4.0, DDR5 and USB 4. AMD will likely pair these chips with RX 6000M laptop graphics cards that are said to be coming out soon.
The street map also shows some other, less exciting chips coming down the pike. Van Gogh and Dragon Crest chips are special designs for low-power devices. Dali and Pollock chips are already on the market, specially developed for manufacturers and geared towards inexpensive laptops. AMD will be releasing Barcelo processors alongside Rembrandt, which will likely use the same branding but target machines with lower specs. That's exactly what AMD does with Ryzen 5000 mobile chips.
Laptop enthusiasts can look forward to it. Although AMD is trudging through the desktop market, it has struggled to break into the mobile space. Supporting the already powerful Zen 3 architecture with RDNA 2 graphics and a more energy efficient design is a winning strategy, but we haven't seen what Intel has in store for 2022.
