AMD's Zen 3, Navi 2 APUs With DDR5 Support May Arrive Next Year

A Twitter user has shared an alleged AMD roadmap that details the chipmaker's plans for its next-generation mobile APUs. Respected hardware leaker kopite7kimi got word that the roadmap looks accurate. Nevertheless,  approach the information with caution since roadmaps are known to change as time progresses.

The roadmap reveals AMD's upcoming mobile APUs for four categories: HP (High Power), LP (Low Power), ULP (Ultra-Low Power) and ELP (Extreme Low Power). Starting from the top, Ryzen 6000 (Rembrandt) will reportedly land next year to replace the existing Ryzen 5000 (Cezanne) lineup. If the the data is accurate, Ryzen 6000 should be based on TSMC's 6nm manufacturing process.

On a microarchitectural level, Ryzen 6000 will utilize an optimized version of Zen 3. The Zen 3+ parts will likely arrive with optimizations in the form of a small frequency bump. According to the leaked roadmap, Ryzen 6000 will support DDR5 and LPDDR5 memory. In terms of graphics, Ryzen 6000 will finally leverage AMD's Navi 2 (RDNA 2) graphics engine, and it'll be the first APU to do so. As usual, Ryzen 6000 will compete in the 45W and 15W power brackets with Rembrandt-H and Rembrandt-U, respectively.

In the LP class, AMD currently utilizes the Ryzen 5000 branding for both its Zen 3 (Cezanne) and Zen 2 (Lucienne) chips. Lucienne-U can be considered a refresh of Renoir, though AMD isn't fond of people calling it that. Lucienne-U uses the Zen 2 cores like its predecessor. It would appear that AMD will replace Lucienne-U in 2022 with Barcelo-U. Barcelo-U will represent a huge upgrade since AMD will endow it with Zen 3 cores. Sadly, the graphics engine is still Vega.

AMD's Van Gogh APUs, which compete in the ULP (Ultra-Low Power) segment, will debut sometime this year. Linux patches have revealed that the Zen 2 chips will sport Navi 2 graphics and support LPDDR5 memory. Dragon Crest is the rumored successor to Van Gogh. Since Dragon Crest seems to utilize the same recipe as Van Gogh, it's rational to assume that Dragon Crest could be a simple refresh.

Apparently, AMD doesn't have anything planned for the ELP category. Pollock, which is based on the Zen and Vega microarchitectures, will continue push forward through 2022.

    I'm really curious to what we will see on the desktop. I have a feeling we won't see anymore cpu's on AM4. And Zen 3+ will be for the AM5+DDR5 platform to get the quirks out of that before Zen 4 launch. This refresh we may see in Q4 2021, then we may not see Zen 4 until Q1 or Q2 2022. And this date my change depending on what Alderlake brings to the table.

    This roadmap seems just dumb enough to be real.
    Like Van Gogh, nobody would expect AMD to add LPDDR5 compatibility to Zen2. I don't think generally anybody would expect AMD to use Zen2 in any new design, especially since everybody thought the point of skipping the 4000 series branding on desktop was to eliminate the mixed-core generation.
    So, sure, 2 more years of Zen2. Great use of your limited 7nm production, AMD.

    Roadmap matches and seems similar to this one, though the information shared is still a bit confusing.

    I think we are being messed with.... I'll let my current desktop rigs ride out the rest of 2021 (I5Clarkdale2010 and I7IvyBridge2012 respectively) ... and see what's available. Previously, stayed with AMD through many K6 Super7 & Athlon SocketA varients until Core 2 Duo became impossible to ignore.

    Looks like it will be a motherboard, cpu, ram, video card and NVMe upgrade for me this time around... and it will be AMD centric again . Perhaps a 570S/670 chipset (assumed name of 570/570S replacement), Zen3+ chip (hopefully a 5950+/6950 16core model will be available), 64GB of DDR4 or DDR5 (depending on what the chipset/motherboard supports), Navi2 video card (haven't bought a discreet card in a while, so this is really up in the air, but i better go with some form of RayTrace support... 6900XT might still be the AMD top end at that point.), and then of course 2 x NVMe M.2 drives...

    One thing is for sure.... I'm positive the PC I build at the end of 2021, start of 2022 will be the last of my professional IT/OT career..... Selling hotdogs once my next build is rendered obsolete...

    no love for desktop APU, and supply will be nonexistent

    if intel doesnt fukk up alder lake, they could recapture significant market share
