New AMD Zen 6 leak points towards huge gaming boost
Zen 6 should be a great CPU architecture for gamers
A new leak from @9550pro on X has revealed details about AMD’s upcoming Zen 6 CPU architecture. This leak supports prior reports that AMD is increasing its L3 cache sizes with its Zen 6 CPUs. AMD is reportedly creating Zen 6 CCDs (Core Complex Dies) with 12 CPU cores and 48MB of L3 cache. Today’s Zen 5 CCD features only eight cores and 32MB of L3 cache. These increased L3 cache sizes for AMD Zen 6 will be great for PC gaming workloads.
AMD are also reportedly making a 32-core CCD with 128MB of L3 cache. These CCDs will likely use AMD’s Zen 6c CPU cores, focusing on silicon density rather than maximised per-core performance.
AMD’s 12-core Zen 6 CCDs are known to use TSMC’s 2nm technology. This tech should give AMD’s new CPUs a power efficiency and density boost. With 50% more cores and 50% more L3 cache, AMD’s Zen 6 CCDs will be much more performant than last-generation CCDs. However, they will also be more expensive. 2nm won’t be cheap…

Zen 6’s L3 cache boost will be great for PC gaming
One trend with AMD’s Ryzen series CPUs is that every increase in per-CCX (Core CompleX) L3 cache delivers increased gaming performance. With Zen 2, AMD doubled its L3 cache size over Zen 1. With Zen 3, AMD created larger CCXs with eight cores instead of four. This gave each core direct access to a 32MB pool of L3 cache, doubling the size of each core’s accessible L3 cache. Since then, L3 cache sizes have remained consistent for Ryzen. However, the introduction of AMD’s X3D technology has boosted the L3 cache sizes of certain chips, delivering breakthrough gaming performance.

| Zen 1 | Zen 2 | Zen 3 | Zen 4 | Zen 5 | Zen 6 | |
| Core Count | 4 + 4 | 4 + 4 | 8 | Â 8 | 8 | 12 |
| L3 Cache | 16MB | 32MB | 32MB | 32MB | 32MB | 48MB |
| L3 Cache Per CCX | 8MB | 16MB | 32MB | 32MB | 32MB | 48MB |
| L3 Cache Per Core | 2MB | 4MB | 4MB | 4MB | 4MB | 4MB |
AMD’s largest generational leaps in gaming performance have always coincided with increases in per-CCX cache sizes. The jumps from Zen 1 to Zen 2 and Zen 2 to Zen 3 were transformative for AMD. Furthermore, the introduction of X3D CPUs pushed the company to the top of the PC gaming market.
With 50% more L3 cache per CCX, we expect AMD’s Zen 6 CPUs to deliver excellent gaming performance. Add on its inevitable X3D-enhanced incarnation, and we expect gaming performance to improve further.
