This design was intended to allow cpu cores to process faster despite the memory latency of main memory access. This site may earn affiliate commissions from the links on this page. The “zen 2” core is a significant update to the historic “zen” architecture.

Significant performance uplift with 2x throughput, doubled core density with up to 64 cores, pcie gen 4.0 support, aiming server epyc rome 7nm cpus.

Zen 2 was replaced by zen 3. Zen 2 combined the cpu cores into core complexes of 4 each, while also dividing the pool of 32mb l3 cache into two smaller pools of 16mb cache each. For performance desktop and mobile computing, zen is branded as athlon, ryzen 3, ryzen 5, ryzen 7, ryzen 9, and ryzen threadripper processors. Eight 7nm chiplets and one 14nm i.
