Rumor | More PCI IDs and codenames support the leaks regarding the absence of Navi iGPUs from AMD's upcoming Ryzen 5000 laptop APUs

Even though the 2021 Ryzen 5000 APUs may only integrate the good old Vega GPU cores, the highly-anticipated Navi iGPUs could make an early appearance with the Van Gogh ultra-low power APUs that could launch sooner than expected, possibly later this year.

The problem with current Ryzen 4000 Renoir APUs is that everyone was expecting AMD to inculde the Navi iGPUs, but this was not possible since the designs were already finalized bi early 2019, and Navi first released in mid-2019. Even so, AMD managed to upgrade the Vega iGPUs with 7 nm transistors, and the performance uplift is thankfully noticeable. Now, surely AMD will include the Navi iGPUs with the Ryzen 5000 APUs, right? Some previous leaks pointed out that this might not be the case, and Twitter user Komachi_Ensaka has recently done some more PCI ID digging, unfortunately offering more support for the leaks.

Komachi points out that the PCI Device ID for the upcoming Ryzen 5000  is 1638 (1636 is Renoir) with a CZN_RENOIR codename. This suggests that the Cezanne models will directly replace the current Renoir chips. Furthermore, this codename also implies that the iGPUs will once again be refined 7 nm versions of the Vega cores, with performance increases similar to what Ryzen 4000 brought over Ryzen 3000 iGPUs. The good news is that the Ryzen 5000 APUs will use modified versions of the Zen 3 cores launching with this year’s Ryzen 4000 desktop CPUs. The Cezanne chips are expected to launch in early 2021 on the AM4 socket.

Interestingly enough, Komachi also points out that the APU lineup codenamed Van Gogh is apparently scheduled to launch between Renoir and Cezanne. Van Gogh is expected to use the current 7 nm Zen 2 cores in conjunction with the newer Navi iGPUs, however, these chips are supposed to be ultra-low power versions to compete with Intel's Y-series. The decision to first add the more powerful Navi iGPUs on such low power chips seems a bit strange. There are also rumors regarding a Rembrandt APU lineup that will be based on Zen 3 core and will most likely include the Navi 2 iGPUs, and these will be launching some time in 2022.

I stepped into the wonderous IT&C world when I was around 7. I was instantly fascinated by computerized graphics, be them from games or 3D applications like 3D Max. I like to keep myself up to date with all the new technologies that get released at an ever increasing rate these days. I'm also an avid SciFi reader, an astrophysics aficionado and, as of late, a crypto geek.
