AMD Zen 6 Could Feature Up to 32 Cores Per CCD
According to new information from Kepler_L2 and InstLatX64, AMD’s Zen 6 core architecture may include up to 32 cores per CCD (Core Complex Die). This information comes as AMD prepares to launch its Zen 5 core architecture, which will debut at Computex 2024, with the first products expected to hit shelves by Q3 2024.
Now, details about Zen 5 and Zen 5C. These new architectures will be smaller than the existing Zen 4 cores, allowing for more CCDs on the CPU package. Zen 5 will have up to 16 CCDs, each with 8 cores, totaling up to 128 cores. In contrast, Zen 5C will include up to 12 CCDs, each with 16 cores, totaling up to 192 cores.
For comparison, the current Zen 4 architecture had a maximum of 12 CCDs, while Zen 4C had up to 8 CCDs. Zen 4C featured two CCXs (Core Complexes) per CCD, each with 8 cores, totaling up to 128 cores. The new Zen 5 and Zen 5C architectures simplify this structure by retaining a single CCX per CCD.
It's noteworthy that the Zen 6 architecture will be available in three configurations: 8 cores per CCD, 16 cores per CCD, and up to 32 cores per CCD. With 16 cores per CCD, one could get up to 32 cores in a dual-CCD part like the Ryzen CPUs, or up to 64 cores using the same CCD layout. However, the highest core count is likely based around the Zen 6C architecture, while the standard non-C cores are used for enthusiast parts.
Having 16 or 32 cores on a single CCD in next-gen AMD Zen-powered CPUs will be excellent for multi-threaded use cases, especially within the Threadripper and EPYC families. For mainstream PC users, AMD is likely to push core counts higher, but many PC games or engines are not currently optimized for such high-core-count chips. In these instances, 3D V-Cache CPU options are more viable and cost-effective. For example, the Ryzen 7 7800X3D, an 8-core part with stacked V-Cache, competes closely with top 16- and 24-core CPUs.
