AMD · EPYC 7002 · 2019 · SP3
The AMD EPYC 7742 is a server processor with 64 cores, released in 2019 at an MSRP of $6,950. It is part of the EPYC 7002 lineup, using the EPYC 7002 platform, and fits the SP3 socket. Internally, it is built on the "Zen 2" architecture. Thanks to AMD Simultaneous Multi-Threading (SMT), each core can handle two instruction streams simultaneously, yielding a total of 128 threads for improved parallelism. The EPYC 7742 has a base clock of 2.25 GHz and can boost up to 3.4 GHz depending on workload and thermal headroom. AMD manufactures the "Zen 2" silicon on a TSMC 7nm process node. This processor supports DDR4 memory across 8 channels, up to 4TB total, with ECC support standard for data integrity in server workloads. It supports both single-socket (1P) and dual-socket (2P) configurations, with 128 lanes of PCIe 4.0 available for storage, networking and accelerators. With a TDP of 225W, the EPYC 7742 runs hot and requires a capable cooling setup. The cache hierarchy consists of 32KB/core of L1, 512KB/core of L2, and 256MB of L3 cache — a substantial cache pool well suited to memory-bound enterprise and virtualization workloads.
2nd Gen EPYC flagship — the first x86 server CPU built on 7nm and the first with PCIe 4.0 support, giving AMD an early I/O bandwidth advantage over Intel's contemporary Xeon lineup.
