The AMD EPYC Embedded 8434P is a server/workstation processor with 48 cores, launched in October 2024. It is part of the EPYC lineup, using the Zen 4c (Siena) architecture with Socket SP6. Thanks to AMD Simultaneous Multithreading (SMT) the core-count is effectively doubled, to 96 threads. EPYC Embedded 8434P has 128 MB of L3 cache and operates at 2.5 GHz by default, but can boost up to 3.1 GHz, depending on the workload. AMD is making the EPYC Embedded 8434P on a 5 nm production node using 35,500 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 Embedded 8434P, which limits its overclocking potential.
With a TDP of 200 W, the EPYC Embedded 8434P is extremely power hungry, which means you need top-notch cooling. AMD’s processor supports DDR5 memory with a six-channel interface. The highest officially supported memory speed is 4800 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 Embedded 8434P uses a PCI-Express Gen 5 connection. This processor lacks integrated graphics, you might need a graphics card.
Hardware virtualization is available on the EPYC Embedded 8434P, 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.
