We have recently seen several reputable rumors confirming that AMD's Zen 4 Raphael desktop processors will be limited to 16 cores with 2 compute units. There were previous rumors of a 24 core model with 3 compute units however that now seems unlikely. While the core counts won't increase some skews may see a TDP increase up to 170 W which should offer some performance uplift. AMD is expected to debut their 5 nm Zen 4 Raphael desktop processors in 2022 which will come with support for PCIe 5.0 and DDR5. The processors will switch to a new AM5 LGA1718 socket and will compete with Intel's Alder Lake-S successor Raptor Lake which could feature 24 cores.
