AMD Ryzen Zen 4 Mainstream Processors Will Come With RDNA2 Integrated Graphics

This is different from the Ryzen 6000 APUs coming next year.

Ever since the launch of Ryzen, all Zen–based CPUs from AMD have come without any integrated graphics. Only their Ryzen–G lineup of APUs carry an iGPU onboard, but those are specially designed to be sold separately as the iGPU option acts as a selling point rather than a nifty add–on. That being said, with the upcoming Zen 4 Raphael CPUs from AMD, we could finally a see major shift in this area.

Thanks to Chips and Cheese and via Videocardz, we now know that AMD is finally ready to debut its mainstream CPUs with integrated graphics for the first time since the original Zen. And, also for the first time, Vega will not be coming back (thank God). The news comes courtesy of the recent Gigabyte hack that leaked several documents containing confidential information about Intel and AMD’s upcoming products.

Zen 4 Hybrid GFX

One page out of the documents reveals the compatibly features for the socket AM5 platform that’s reportedly launching alongside Zen 4 CPUs. In the compatibility chart (attached below) there are three different types of AM5 processors listed, all based on Family 19h which represents the mainstream Zen 4 microarchitecture. All of them come with “Hybrid GFX support” as mentioned in “On–chip graphics” row.

Hybrid GFX support alludes to the blend of graphics options that’ll be available on the CPU. You can either use the integrated graphics present inside the processor or dedicated graphics in the form of a discrete GPU. Because the CPU now has an integrated graphics chip inside, it’s compatible with both on–board and dedicated graphics—hence, hybrid GFX.

Display Connections

Moreover, we can see “3 Type–C” mentioned with each of the three processors. We already know that upcoming Zen 4 processors will come with four DisplayPort interfaces, but now with the addition of this Type–C description, it’s confirmed that out of those four DP interfaces, three can be routed to USB–C in DisplayPort Alt Mode. The chart does not mention support for any connectivity standards such as HDMI 2.1 or DisplayPort 2.0, however.

That being said, the AM5 platform will feature 4x more PCIe Gen4 lanes that, in some cases, will be used to power a USB4 hub that can then power two Thunderbolt ports running on DisplayPort 2.0. Along with that, DP 2.0 support was recently added for Linux via patches from AMD. Hence, it’s likely that DisplayPort 2.0 will be supported on Zen 4 CPUs with iGPUs.

Furthermore, Chips and Cheese was also able to find schematics for converting the DP signal to HDMI 2.1, so we can check that off the list too. All in all, there’s a high probability for support for next–gen connectivity options. In addition, there should be enough bandwidth to drive a 4K display running at 60Hz on these new Zen 4 processors. Although, I doubt that any game would actually be able to run at that spec on integrated graphics.

RDNA 2, Not Vega

Now, the real kicker here is that the integrated graphics aren’t based on the outdated Vega architecture. Instead, the upcoming Zen 4 CPUs will feature iGPUs based on RDNA2, an upgrade that will astronomically increase the performance and efficiency. The contemporary Ryzen 5000 series APUs come with Vega graphics which severely holds them back from their true potential. So, it’s easy to understand and get excited about the improvements we’re about to see in Ryzen Zen 4 mainstream CPUs, or should I say APUs.

AMD Ryzen F–Series?

Lastly, the documents also tell us that not all Zen 4 processors will come with iGPUs. So, apart from Zen 4 Ryzen–G APUs and mainstream Zen 4 CPUs, there will also be other Zen 4 chips that will lack integrated graphics. “Some OPNs…may not support GFX“, reads the document. This could be a sign that AMD wants to walk in the same line as Intel. Never thought I’d say that sentence but here we are.

Since, now, AMD will kit its mainstream CPUs with onboard graphics, perhaps they want to follow Intel’s product segmentation. Intel releases its F–series processors that are identical to their normal SKU, but come without iGPUs. So, it’s not unreasonable to see how AMD would also want to do the same with Zen 4. This way, AMD can sell cheaper SKUs to those who don’t care about the iGPU and sell the fully–stacked SKUs to those who need it.

When Can We Expect Zen 4 With RDNA2?

AMD will release RDNA2 mobile APUs based on the Zen 3 architecture next year either for notebooks or as next–gen desktop APUs. We don’t know if they’ll be on the AM4 platform or AM5 if they do launch on desktop, but if we get the mobile version, it’ll be on the FP7 socket. Regardless, the upcoming Zen 4 “Raphael” processors with integrated graphics are different from those.

Zen 4 is set to release next year and will be fabricated on TSMC’s 5nm process. We’re not sure whether it’ll be called Ryzen 6000 or 7000 since the actual 6000–series based on Zen 3+ architecture has been canceled. Therefore, both names are on the table. Also on the table is the 25% IPC uplifts arriving with Zen 4. Pair that with RDNA 2 integrated graphics and you have one hell of a processor.
