The leaker @Brolly_x1 Shared a road map on Friday detailing AMD’s mobile plans by 2022. The road map confirms several leaks and rumors and adds context, indicating that AMD is working on a Zen 3+ refresh for mobile, to be launched in 2022.
What matters are the two green sections of the road map. Rembrandt is the code name for the temporary Ryzen 6000 mobile chips. We don’t know if the name will end with AMD, but it’s as good a guess as any. The road map shows that these mobile chips will be built on the 6nm Zen 3+ architecture, which is a modification of the currently available 7nm Zen 3 architecture.
Assuming that AMD will continue to partner with semiconductor manufacturer TSMC, these chips will show slight improvements over their Zen 3 counterparts. The 7nm process and the 6nm process are closely related in TSMC, with the latter showing minor improvements. Originally, Rembrandt is not an entirely new generation of processors.
The mobile chips will also have RDNA 2 graphics cores. AMD’s current Ryzen 5000 mobile chips still use the older Vega graphics core, so Rembrandt will give a significant boost to gaming laptops. These cores can also provide hardware-accelerated ray tracing, just like the rDNA 2-based RX 6000 graphics card. They are rumored to offer up to 50% increase in graphics performance.
The Rembrandt “U” chips are targeting thin and light laptops with only 15 watts of power, while the Rembrandt “H” chips will go up to 45 watts for dedicated gaming laptops. Both chips will have support for PCIe 4.0, DDR5 and USB 4. AMD will pair these chips with the RX 6000M laptop graphics card, which is rumored to be launched soon.
The road map also reveals some other, less exciting chips coming down the pike. Van Gogh and Dragon Crest chips are special designs for devices with very high power. Dali and Pollock chips are already on the market, made specifically for manufacturers and targeted at budget laptops. AMD will release the Barcello processor with Rembrandt, possibly using the same branding but targeting low-spec machines. This is what AMD is doing with Ryzen 5000 mobile chips.
Laptop enthusiasts have a lot to look forward to. Despite AMD’s entry into the desktop market, it has struggled to gain a foothold in the mobile space. Strengthening the already powerful Zen3 architecture with rDNA2 graphics and more power-efficient design is a win-win strategy, but we haven’t yet seen what Intel has for 2022.
