Rumor claims AMD Zen 6 will feature 48MB of L3 cache — keeping L3 cache-to-core ratio the same as Zen 5 with Zen 6's 12-core CCD

Increasing Zen 6 to 48MB of L3 cache per CCD will keep the core to L3 cache ratio the same as Zen 5.

Resident leaker HXL on X claims that Zen 6 will feature 48MB of L3 cache, keeping the L3 cache-to-core ratio the same as in previous generations.

HXL also claims that Zen 6 will feature a larger footprint for the die itself, likely due to the extra cores being added to each CCD. Zen 6 will allegedly sport a 76mm² die, which is 7% larger than Zen 5's 71mm² die. In fact, if this info is true, Zen 6 will be the first architecture to have a larger footprint than its predecessors since Zen 3.

One of the biggest changes we are seeing from Zen 6 leaks is the architecture's introduction of a 12-core CCD for the standard Zen 6 core dies (excluding Zen 6c). This is a massive change for Ryzen as a whole, and will enable 12-cores to share data with each other across a unified L3 cache. AMD hasn't confirmed the 12-core CCD, but it's been a consistent touchstone of rumors for nearly a year.
