AMD Zen 4 Mobile APUs with Up To 16 Cores Are Supposedly Coming in 2023

Finally bringing the mobile core count on par with the desktop.

The recent launch of Alder Lake processors has stirred up the highly-contested CPU market once again, and with the company now set on revealing its mobile lineup at CES 2022, it’s high-time the competition is ready for a prompt response. While AMD is also expected to reveal its Ryzen 6000 “Rembrandt” H-Series of laptop APUs alongside Intel at CES, it’s actually what will come after that excites us the most.

Ryzen 6000 Rembrandt

Ryzen 6000, or Rembrandt-H, the mobile APU lineup that’s about to launch in a couple of months will be based on the new 6nm Zen3+ architecture and will mark the debut of RDNA 2 integrated graphics on a APU. We don’t know the clock speeds for sure yet, but only expect a marginal improvement over Ryzen 5000, at best. Still, a jump from 7nm to 6nm process and substantially improved graphical capability is enough to warrant a new generation.

After Ryzen 6000, AMD will release Zen4, its next-generation CPU architecture that will feature RDNA 2 graphics by default, in turn, effectively making the processors APUs. For the first time since Ryzen’s introduction, mainstream (non-Ryzen G) desktop processors from AMD will have an iGPU onboard as standard, just like Intel. This is an area where Intel has largely always had an advantage but AMD is looking to close the gap.

Zen4 Mobile APUs

Alongside the desktop processors, AMD will also launch mobile APUs for laptops based on the Zen4 microarchitecture, codenamed Phoenix-H and Raphael-H. This is where the real fun begins. There have already been some rumors and reports suggesting that AMD will be doing something to gain an edge over Intel’s newly gained lead in core count thanks to Alder Lake, and it seems like Zen4 mobile APUs are the answer.

According to Greymon55 on Twitter, Zen 4-based Raphel-H laptop APUs from AMD will feature a core count of up to 16 cores and 32 threads, up from the standard maximum of 8 cores and 16 threads we’ve seen in Ryzen mobile APUs since Zen 2. Phoenix-H, on the other hand, will be more of an incremental upgrade over its predecessor as it will maintain the 8-core, 16-thread topology established back with Zen 2.

Zen4 laptop and desktop APUs will most likely be called “Ryzen 7000” because the Rembrandt-H lineup of mobile APUs based on Zen3+, and potentially the Vermeer-X3D lineup of desktop APUs based on Zen3D, will be called “Ryzen 6000”. Hence, it only makes sense that Ryzen 6000 in 2022 will be followed by Ryzen 7000 in 2023.

As of now, Ryzen 7000 desktop is codenamed “Raphael” and Ryzen 7000 mobile is codenamed “Phoenix”. And, Greymon’s tweet confirms that AMD will essentially continue its standard mobile APU release in the form of Phoenix-H but, this time, the desktop segment aka Raphael will be brought down to the mobile platform (Raphael-H) to create a flagship mobile APU to compete with Intel.

Ryzen 7000 Phoenix-H

Phoenix-H is supposed to launch on the FP8 mobile platform, which would be the direct successor to the brand-new FP7 platform we’re about to see with Ryzen 6000 mobile. That tells us that FP7 will essentially last only one generation and will be replaced with FP8 next year. Currently, the Ryzen 5000 Cezanne-H mobile APUs are on the FP6 platform, just to put that into context.

As mentioned before, Phoenix-H is a relatively small but still important update. It will feature a maximum core count of 8-cores and 16-threads along with upgraded RDNA 2 iGPUs and the entire family will have TDPs below 40W. Phoenix-H will likely be aimed at the budget segment of the market and target a mass audience who need a reliable and fast new laptop, but don’t mind not having the top-of-the-line specs.

Ryzen 7000 Raphael-H

Speaking of top-of-the-line, Raphael-H will be AMD’s flagship laptop APU with Zen4. It is set to sport a maximum of 16 cores and 32 threads, along with a boosted max L3 Cache of 32MB. The TDPs will be above 45W and upto 65W for this family and, as you’ve guessed by now, this lineup of flagship APUs will be found in only the highest of high-end laptops and a few mere mortals will be able to get their hands on it.

Okay, I may be exaggerating a bit there but, trust me, it will be a exclusive product and it will carry a sort of prestige with it considering it would be the best mobile APU in town, if Intel doesn’t produce an upset. Even the top-end Ryzen 5000 laptop APUs are hard to come by these days and the flagship APU in that family, the 5980HX, is literally available in only one laptop so far.

Unlike the upcoming Rembrandt-H lineup and 2023’s Phoenix-H family, we don’t know nearly as much about Raphael-H. Heck, we didn’t even know Raphael existed as a mobile platform, up until now, the Raphael codename was closely associated with desktop Ryzen 7000 only. But, we do know that Raphael-H is supposed to be the cream of the crop and that it will most likely feature an upgraded Navi GPU architecture as compared to its sibling Phoenix-H.

Recap

If you still can’t wrap your head around all the codenames and release dates, here’s a simple rundown for you:

2021: Ryzen 5000

Desktop codename: Vermeer

Laptop/Mobile codename: Cezanne

Microarchitecture: Zen3 (based on 7nm fabrication process from TSMC)

2022: Ryzen 6000

Desktop codename: Vermeer-X3D (unconfirmed rumor)

Laptop/Mobile codename: Rembrandt

Microarchitecture: Zen3+ for mobile, Zen3D for desktop [rumor] (based on 6nm fabrication process from TSMC)

2023: Ryzen 7000

Desktop codename: Raphael

Laptop/Mobile codename: Phoenix (standard), Raphael (high-end)

Microarchitecture: Zen4 (based on 5nm fabrication process from TSMC)


Hopefully, that gives you a good idea of what AMD has in store for us for the next 2 years. It will be very interesting seeing this race between the CPU giants fold out now that everyone seems to have big things going on for them. Intel currently has the lead in mobile core count due to its 14-core, 20-thread mobile i9-12900 processor and AMD is likely to trail that for at least 2022. But, come 2023 when AMD purportedly comes out with a 16-core, 32-thread mobile APU, that’s when this battle will get real feisty.
