Can someone explain if the 3D Vcache are stacked on top of each other or side by side.

If they are stacked then why not 9800X3D2?



The 99xx chips have two CPU dies, and one cache die is on each CPU die.


The 3D V-Cache sits underneath only one of the CCDs. See https://en.wikipedia.org/wiki/Ryzen#Ryzen_9000.


That's what's different about this one. "Enter the Ryzen 9 9950X3D2 Dual Edition, a mouthful of a chip that includes 64MB of 3D V-Cache on both processor dies, without the hybrid arrangement that has defined the other chips up until now."


Did you forget which thread we are on?


Oh heh, I thought they were asking about the X3D. My bad ><.
