Architecture
Nothing is currently known about the architectural improvements that are being done for Zen 3.
Key changes from Zen 2
- Unified 8-core CCX with 32 MiB L3$ available to all 8 cores equally
- Wider and more flexible issue in floating-point and integer engines
- Increased number of loads and stores, improved prefetching
- Increased branch prediction bandwidth, "zero-bubble" branch prediction
- Improved µop cache
- [Unconfirmed] 7 nm+ process (from 7 nm), 20% more density and 10% power reduction compared to Zen 2. EUV (Extreme Ultraviolet) lithography 7nm+.
