AMD Zen 6 To Feature Three CCD Configurations: 8, 16, & Up To 32 Cores, Zen 5C Packs 16 Cores In Single CCX

AMD's next-gen Zen 5 and Zen 6 core configurations have allegedly been revealed with the latter featuring up to 32 cores per CCD.

AMD Zen 6 CPUs Could Pack Up To 32 Cores Per CCD, Zen 5C Packs 16 Cores In A Single CCX

The newest information on the next-gen AMD Ryzen Zen core configurations comes from Kepler_L2 & InstLatX64. We know that AMD is on the verge of launching its Zen 5 core architecture which will make a formal debut at Computex 2024 with the first products expected to hit shelves by Q3 2024.

So first up, we have the information about the Zen 5 and Zen 5C core configurations. AMD's Zen 5 & Zen 5C cores are expected to be smaller than the existing Zen 4 cores which opens up space to incorporate more CCDs on the CPU package. While Zen 4 deployed up to 12 CCDs and Zen 4C had up to 8 CCDs on the top EPYC chips, the latter had two CCXs, each with 8 cores for up to 128 cores.

But with the coming generation, AMD is going to stack as many as 16 CCDs with Zen 5 and 12 CCDs with Zen 5C architectures. While Zen 5 will retain the same single CCX design within the CCD with a total of 8 cores for up to 128 cores, the Zen 5C chips will incorporate a single CCX with a total of 16 cores for up to 192 cores. Following is the breakdown of how the next-gen Zen 5 and Zen 5C stack up against the Zen 4 and Zen 4C chips:

• Zen 5C: Up To 12 CCDs (EPYC) / 16 Cores Per CCD / 1 CCX per CCD = Up To 192 Cores
• Zen 4C: Up To 8 CCDs (EPYC) / 16 Cores Per CCD / 2 CCX per CCD = Up To 128 Cores
• Zen 5: Up To 16 CCDs (EPYC) / 8 Cores Per CCD / 1 CCX per CCD = Up To 128 Cores
• Zen 4: Up To 12 CCDs (EPYC) / 8 Cores Per CCD / 1 CCX per CCD = Up To 96 Cores

In addition to the Zen 5 and Zen 5C architectures, it is alleged that AMD's Zen 6 core architecture, the follow-up to Zen 5, will be available in three configurations. These configurations would include 8 cores per CCD, 16 cores per CCD, and up to 32
