Raphael with Zen 4 with 16 cores and 170W (Update)

While the launch of the next generation at Intel is due this fall, it will still be some time before AMD launches the next generation of Ryzen. Nevertheless, there is now a new surge of possible information about the next processors, which will then be based on the Zen 4 architecture. What we already know from some leaks (or rather probably know, because they are still rumors) is that the codename of the desktop processors is Raphael. The individual Zen 4 cores are called Persephone and a CCD with eight of these cores is called Durango. Since the basic structure of the processors with one IOD and two CCDs should not change, one could also assume that AMD for the desktop again at 16 cores. Rumors also spoke of a variant with 24 cores, which would then require three CCDs (and also a modified IOD). However, two sources are now established: Raphael will be available with a maximum of 16 cores. However, this does not rule out the possibility that AMD will not increase the number of CCDs and thus the number of cores for a second Ryzen generation based on Zen 4.

The presence of an integrated graphics unit is also confirmed once again. This is apparently located in the IOD and is based on the RDNA-2 architecture. Patrick Schur, usually always very well informed with AMD hardware, also confirms the TDP of up to 170W and the production in 5nm. The IOD (CIOD3 - Consumer IOD of the third generation) should switch to production in 7nm. The TDP of up to 170W has already been hotly debated, but here we should wait and see what exactly is meant by it. Currently, AMD calls a maximum TDP of 105W for its Ryzen desktop processors. Via the PPT (Package Power Tracking), however, the actual power limit of the processors is specified and this is currently 142W which in practice also corresponds to the actual maximum consumption.

At the end of the year, AMD wants to have Ryzen processors with 3D V cache manufactured. These should then come on the market in the first quarter of 2022. Whether this is the Zen3+ refresh alias Warhol, or AMD will use the 3D V cache on Zen 3 CCDs here, is not known. Raphael alias Ryzen 7000 series will certainly wait until mid-2022. Patrick Schur goes one more way and names the TDP classes that will be used for Raphael. Accordingly, it starts at 65W and over 95W, 105W, 120W up to 170W. A Ryzen 5 5600X currently starts at 65W, all faster Ryzen models are guided with 105 W. According to AMD's definition, the processors do not consume more than 105 W. However, the PPT (Package Power Tracking) reaches up to 142 W. If the PPT factor of 1.35 remains based on the TDP, the processors with a TDP of 170W achieve a maximum power consumption of 230W.
