The AMD EPYC 7R12 was a server/workstation processor with **48 cores**, launched in the second quarter of 2020. It is part of the EPYC lineup, using the **Zen 2** architecture with **Socket SP3**. Thanks to **Simultaneous Multithreading (SMT)**, the core-count is effectively doubled, to **96 threads**. To further increase overall system performance, up to **two EPYC 7R12 CPUs** can work together in a multi-processor (SMP) configuration.

EPYC 7R12 has a **192 MB of L3 cache** and operates at a **base frequency of 2.2 GHz**, with a **maximum boost frequency of 3.3 GHz** depending on workload conditions. AMD is manufacturing the EPYC 7R12 on a **7 nm production process**, offering improved efficiency and performance. The multiplier is locked, which limits overclocking potential.

With a **TDP of 200 W**, the EPYC 7R12 requires robust cooling solutions to maintain optimal performance. The processor supports **DDR4 memory** with an **8-channel interface**, significantly enhancing memory bandwidth. **ECC memory is supported**, ensuring data integrity in mission-critical applications.

For communication with other system components, the EPYC 7R12 utilizes **PCIe 4.0**, providing high-speed connectivity for storage and expansion devices. This processor **lacks integrated graphics**, so a dedicated GPU may be necessary for graphical workloads.

**Hardware virtualization (AMD-V & AMD-Vi)** is fully supported, improving virtual machine performance. Additionally, the processor includes **advanced security features** such as **Secure Memory Encryption (SME) and Secure Encrypted Virtualization (SEV)**, making it ideal for enterprise and cloud environments.

The EPYC 7R12 is optimized for **high-performance computing (HPC), cloud workloads, and data center applications**, delivering exceptional scalability and efficiency.
