Process technology

Zen 3 will be fabricated on TSMC's 7nm+ process.


Nothing is currently known about the architectural improvements that are being done for Zen 3.

Key changes from Zen 2

  • 7 nm+ process (from 7 nm) , 20% more density and 10% power reduction compared to Zen 2. EUV (Extreme Ultraviolet) lithography 7nm+.
  • Unified 8 core CCX with 32MB+ L3$ available to all cores equally
