AMD confirms Ryzen 9 7900X3D architecture, with 6 cores per CCD

At CES 2023 this year, AMD released three Zen 4 architecture desktop processors that use 3D vertical cache technology: Ryzen 9 7950X3D, Ryzen 9 7900X3D, and Ryzen 7 7800X3D, all with a TDP of 120W. The L3 cache capacity of all three processors has been increased by 64MB. Both Ryzen 9 7950X3D and Ryzen 9 7900X3D, which were released on February 28th, are dual-CCD models, with only one CCD having an additional SRAM.

Although AMD lifted the embargo on the first batch of Ryzen 7000X3D series processors, most of the reviews focused on the Ryzen 9 7950X3D, and Ryzen 9 7900X3D was rarely mentioned. It is not clear how the cores are allocated, but initial tests show that it is faster than Ryzen 9 7900. Twitter user @aschilling has revealed that AMD has officially confirmed that the 12 cores of Ryzen 9 7900X3D are evenly distributed between the two CCDs, meaning that each CCD has 6 cores.

Soon, Ryzen 9 7950X3D and Ryzen 9 7900X3D will be available for purchase, providing gamers who plan to build an AM5 platform with more options. However, some gamers may still have trouble deciding which processor to choose, provided that AMD does not limit the supply of Ryzen 7000X3D series processors.
