A bevy of AMD Renoir Ryzen 4000 APUs for desktop leak, 65W Core i3 and Core i5 Comet Lake-S in potential trouble

AMD Renoir Ryzen 4000 for laptops has been pretty impressive so far in both 15W and 35W TDP tiers. We have been expecting Renoir to make its way to the desktop in a 65W TDP variant as well and looks like we might be seeing the first mentions of these processors in the wild. Igor's Lab has managed to get hold of Ordering Part Numbers (OPNs) that offer quite a bit of information about the specs of the yet unannoucned Renoir desktop APUs. 

In all, there are 22 OPN numbers listed. There aren't any marketing names given yet but 12 of these OPNs have detailed specifications available, which we will get to shortly. Overall, we see that the desktop Ryzen 4000 APUs offer either 6, 7, or 8 Compute Units (CUs) on the GPU, which equates to 384, 448, and 512 Stream Processors (SPs), respectively. In all probability, these will be grouped accordingly as Ryzen 3, Ryzen 5, and Ryzen 7 SKUs.

Even the lowest 6 CU APU should be able to afford decent 1080p gameplay at medium settings without the need to purchase a discrete GPU, not to forget the fact that the new Renoir APUs can offer up to 59% higher performance than the previous generation despite still being on Vega. Renoir APUs also support DDR4-3200 RAM as standard spec, which should help with much improved iGPU performance.

12 of these 22 OPNs have detailed specifications available of which six are rated 35W (GE series) and six are 65W (G series) TDP. Of particular interest are the OPN numbers 100-000000145 and 100-000000146. Both these OPNs are feature identical specifications, which may mean that these could land up as processors for different regions or that one of these could be a Pro variant for business. Either ways, these SKUs are 8-core 16-thread parts with a base clock of 3.6 GHz and a boost up to 4.45 GHz. The 8-CU GPU boost clock is indicated as 2,100 MHz, which is impressive. All this is within a 65W TDP envelope. 

Assuming these specs are true, entry-level desktops stand to be more powerful than ever. If priced right, Renoir Ryzen 4000 may give tough competition to the Intel Comet Lake-S Core i3 and Core i5 65W desktop processors as users can now avail great multi-core performance combined with a capable iGPU right out of the box. Renoir desktop APUs are expected to launch in the coming months before AMD unveils the Zen 3 Ryzen 4000 CPUs.
