AMD EPYC Embedded 3255 Review
AMD EPYC Embedded 3255 embedded processor, 8C/16T 2.5 GHz base clock, boosting up to 3.1 GHz, 25-55W TDP, SP4r2 platform.
The AMD EPYC Embedded 3255 is an AMD embedded processor in the EPYC Embedded 3000 Series lineup, built on the SP4r2 platform. It offers 8C/16T at 2.5 GHz base clock, boosting up to 3.1 GHz within a 25-55W power envelope. Designed for long-lifecycle embedded and industrial designs rather than consumer desktops, it targets systems needing extended availability and predictable performance.
Performance and Architecture
With 8C/16T, the AMD EPYC Embedded 3255 runs 2.5 GHz base clock, boosting up to 3.1 GHz. Cache totals 4 MB L2 and 16 MB L3. As an embedded part, it targets industrial, networking, and edge-compute designs that need long-term supply stability.
Platform and Connectivity
The AMD EPYC Embedded 3255 is built for the SP4r2 infrastructure. It supports DDR4-2667 memory via a Dual Channel w/ECC controller. I/O includes 32L Gen3 PCIe lanes. Networking support includes 4x 10GbE.
Comparison to Alternatives
Within this catalog's embedded listings, the AMD EPYC Embedded 3255 sits alongside other EPYC Embedded parts, differentiated mainly by core count, clock speed, and TDP. Buyers should weigh this against consumer desktop or server parts only when long-lifecycle embedded availability matters more than raw price or upgrade cadence.
