Zen 6 CCD size reportedly stays close to Zen 5 while adding cores and L3
A new CCD sizing claim is making the rounds, and yes, the numbers have already been shared publicly. The figures shared by HXL. If the numbers hold, Zen 6 would move from 8 to 12 cores per CCD and from 32MB to 48MB of shared L3. That is a 50% jump in both core count and L3 capacity. The reported die area change is about 5 mm², or roughly 7% versus the Zen 5 figure in the same list.
For context, Zen 5 desktop Ryzen 9000 chips already show how AMD kept CCD area tight on a newer node. AMD’s Ryzen 9000 uses a TSMC N4 process for CPU cores, and mainstream parts like Ryzen 7 9700X carry 32MB of L3. Coverage of the Zen 5 CCD has also put the compute die at about 70.6 mm², staying close to Zen 4’s CCD size.
- Zen4 CCD: 8 Core 32MB L3 TSMC N5 ~72 mm2
- Zen 5 CCD: 8 cores, 32MB L3, TSMC N4, ~71 mm²
- Zen 6 CCD: 12 cores, 48MB L3, TSMC N2, ~76 mm² 🆕
A similar size target for Zen 6 is good news for cost and yield for chiplet desktop and server parts. A larger per-CCD core count could also shift how AMD bins products across one-CCD and two-CCD SKUs, depending on clocks, power, and cache behavior.
At this point, everyone knows this, but this also confirms AMD will have no issue adding the new Zen6 CCDs to the upgraded AM5 package, there’s enough room for that already.
The Zen 6 architecture will power several AMD products, but the focus is on Next-Gen Ryzen, which we tend to refer to as Ryzen 10000. The (still) unofficial codename for the series is Olympic Ridge, while Zen6 will also make its way to Medisa Point mobile series. For now, this is just a rumor, though, as AMD has not confirmed Zen 6 CCD specs, cache size, or die area.
