A new leak has revealed what the next-generation AMD Zen 7 desktop processor might look like, including the chipset/CCD layout, size, and location on the packaging substrate.One of the key changes in Zen 7 is the transition to a 16-core CCD, which is a noticeable upgrade compared to existing 8-core consumer chipsets.

According to the latest revelation from Moore’s Law Is Dead, the flagship AMD Zen 7 desktop processor, codenamed Grimlock Ridge, will be equipped with two 98mm² Silverton CCDs, plus a 155mm² I/O chip.

Each CCD is expected to be equipped with up to 16 Zen 7 cores, which is twice the number of cores in current Zen 5 CCDs. Likewise, each core is said to have 2MB of dedicated L2 cache, twice as many as Zen 5 cores.

However, the average L3 cache per core has not changed, 64MB per 16-core chip, 4MB per core, and an additional 3D cache layer can add 160MB of L3 cache.That is, the total cache of each CCD is 224MB, and the total cache of each 32-core CPU is 448MB.

In addition to this 32-core processor, AMD is reportedly also developing a cost-optimized version based on the 56mm² Silverking CCD, with only 8 cores per CCD.

This design eliminates 3D caching and reduces bandwidth, which, if true, means AMD will have a stronger market segment in the desktop market than ever before.

On mobile devices, AMD reportedly plans to launch two main designs, Grimlock Point and Grimlock Halo.

Among them, Grimlock Point uses a single-chip chipset, which not only contains all I/O functions, but also provides four Zen 7 classic cores and eight Zen 7c cores, for a total of 12 cores.

The tipster pointed out that these cores may also be paired with an unknown number of LP (low power consumption) cores. At the same time, this main chipset can also be connected to an optional Silverking 8-core CCD, with a total core count of 20 (excluding LP cores).

The higher-end Grimlock Halo is equipped with a 20-core single chip (8 Zen 7+12 Zen 7c), and can be expanded with two additional 8-core chips to create a 36-core mobile performance monster.

Overall, Zen 7 will bring a 15-25% IPC improvement over Zen 6, and will use TSMC’s A14 process technology.It has been previously reported that Zen 7 may be compatible with the existing AM5 platform, but it has not yet been officially confirmed. Since Zen 7 is still a long time away from its official release, the specific specifications are still variable.
