The AMD EPYC 4124P is a server/workstation processor with 4 cores, launched in May 2024, at an MSRP of $149. It is part of the EPYC lineup, using the Zen 4 (Raphael) architecture with Socket AM5. Thanks to AMD Simultaneous Multithreading (SMT) the core-count is effectively doubled, to 8 threads. EPYC 4124P has 32 MB of L3 cache and operates at 3.8 GHz by default, but can boost up to 5.1 GHz, depending on the workload. AMD is making the EPYC 4124P on a 5 nm production node using 6,570 million transistors. The silicon die of the chip is not fabricated at AMD, but at the foundry of TSMC. The multiplier is locked on EPYC 4124P, which limits its overclocking potential.
With a TDP of 65 W, the EPYC 4124P consumes typical power levels for a modern PC. AMD’s processor supports DDR5 memory with a dual-channel interface. The highest officially supported memory speed is 5200 MT/s, but with overclocking (and the right memory modules) you can go even higher. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the system, EPYC 4124P uses a PCI-Express Gen 5 connection. This processor features the Radeon Graphics integrated graphics solution.
Hardware virtualization is available on the EPYC 4124P, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) can run on this processor, boosting performance for calculation-heavy applications. Besides AVX, AMD has added support for the newer AVX2 and AVX-512 instructions, too.
