AMD Ryzen 5 Processors and Core CCX Allocation

One of the biggest questions that was buzzing around the HardForum last night after the AMD Ryzen 5 Processor Family Introduction was how the cores and CCX units are going to be present on the 4-Core and 6-Core parts. We reached out to AMD this morning and got a definitive answer. Keep in mind that AMD is currently only building one Ryzen die that has 8-Cores.

The cores are symmetrically disabled (e.g. 3 cores + 3 cores, or 2 cores + 2 cores, etc.) in the CCXes.

  • The 1700, 1700X and 1800X are 4+4 and 16M L3, 4MB L2 (512kb/core)

  • The 1600X and 1600 are 3+3 and 16M L3, 3MB L2 (512kb/core)

  • The 1500X is 2+2 and 16M L3, 2MB L2
