AMD EPYC Embedded 3255

The AMD EPYC Embedded 3255 is an 8-core, 16-thread server/workstation processor from the EPYC 3005 series, built on the Zen architecture (codename Snowy Owl) at GlobalFoundries' 14 nm process. It integrates 4,800 million transistors on a 213 mm² die, with 96 KB of L1 and 512 KB of L2 per core plus a shared 16 MB L3 cache. Released in February 2018, this embedded part remains in active production, targeting compact server and network infrastructure rather than consumer desktops.

Benchmark Performance

The data set lists no individual benchmark scores for this processor — the average benchmark score field reads 0 and the benchmark array is empty. What the data does provide is a percentile ranking of 50 against all CPUs in the database, meaning the EPYC Embedded 3255 sits exactly at the median of the tracked processor population. In other words, half of all recorded CPUs are expected to be faster and half slower, a neutral position that reflects its embedded-market orientation rather than a performance flagship. Without nearest-rival entries, there are no deltaPct values to cite; the percentile is the only quantitative performance anchor available.

This median placement is consistent with an 8-core Zen design clocked at 2.50 GHz base and 3.10 GHz boost — a configuration that is neither at the top nor the bottom of the spectrum. The absence of benchmark data also means the 0 average score should not be read as a literal performance result; it indicates no recorded runs populate the database. For a hardware analyst, the percentile is the actionable figure: at the 50th mark, the 3255 is a middle-of-the-road embedded processor in raw compute terms. Future benchmark entries would refine this picture, but the current data suggests a balanced, unremarkable compute profile.

Platform and Compatibility

The EPYC Embedded 3255 uses the AMD BGA SP4r2 socket, a ball-grid-array package that is soldered to the motherboard. This has direct implications for upgradeability: a BGA socket does not allow processor swaps, so the platform is fixed at purchase time. The 3255 belongs to the EPYC 3005 series, which is a dedicated embedded line rather than a mainstream desktop family. Memory support is DDR4 over a dual-channel bus, with a peak memory bandwidth of 42.7 GB/s. ECC memory is supported, a critical feature for server and workstation reliability — the data confirms ECC is present, so error-correcting DIMMs can be used to protect against bit rot in long-running workloads.

For expansion, the processor exposes 32 PCIe Gen 3 lanes (CPU only), providing a solid I/O foundation for NVMe storage, network controllers, or accelerators. Integrated graphics are not part of the CPU die; the data notes graphics appear "on certain motherboards" as a chipset feature, so any display output depends on the specific board design. The production status is Active, meaning the part is still being manufactured and available for new designs. The release date of February 2018 places it in the early Zen era, and the fixed BGA nature means the upgrade path is limited to the motherboard's other features rather than a future processor drop-in.

Single-Thread vs Multi-Thread Behavior

The 3255 pairs 8 physical cores with 16 threads via simultaneous multithreading, giving it a wide parallel footprint. The base clock of 2.50 GHz and boost clock of 3.10 GHz define the single-thread envelope; the boost represents the maximum frequency a single core can reach under light load. The gap between base and boost is modest, which suggests the design prioritizes sustained all-core operation over aggressive single-core turbo — a sensible trade-off for embedded server workloads that run many threads continuously.

Multi-threaded performance benefits from the 16 threads and the shared 16 MB L3 cache, which reduces cross-core communication latency. Single-thread performance is bounded by the 3.10 GHz boost and the Zen architecture's per-core IPC; with 96 KB of L1 and 512 KB of L2 per core, the cache hierarchy is generous for the era. For real workloads, this split means: highly parallel tasks — database queries, virtualization, packet processing — will leverage the 16 threads effectively, while lightly threaded applications that depend on a single core will be limited by the 3.10 GHz ceiling. The 2.50 GHz base clock is the floor for all-core loads, and with 8 cores active the processor will likely settle near that figure under sustained stress. Benchmark results indicate a balanced design: no extreme single-thread burst capability, but a wide, consistent multi-thread throughput profile that suits the embedded server role.

How It Compares

The FACT PACK's nearestRivals array is empty, so there are no named rival processors with scores or deltaPct values to cite. This is an unusual situation for a benchmark database entry and limits direct quantitative comparison. What can be stated is the percentile position: at 50, the 3255 sits at the median of all CPUs in the database. Without rival entries, no percentage-based deltas can be computed, and no competitor can be declared ahead or behind by a specific margin.

The data implies the 3255 occupies a middle tier — not a performance outlier in either direction. In the embedded market, this median placement is reasonable for an 8-core Zen part with a 55 W TDP; it is neither a high-core-count monster nor a low-power Atom-class chip. The absence of rival data means conclusions must be drawn from the architectural parameters: 8 cores, 16 threads, 3.10 GHz boost, and 42.7 GB/s memory bandwidth. Against a hypothetical mainstream server CPU, the 3255 would likely trail on raw core count but lead on power efficiency — though such a claim cannot be quantified here. The honest reading is that the 3255 is a mid-pack embedded processor with no direct competitor entries recorded in this database.

Who Should Consider It

The EPYC Embedded 3255 targets the server/workstation market segment, per the data. For server workloads — virtualized environments, network appliances, storage controllers — the 8 cores and 16 threads provide ample parallelism, and the ECC memory support ensures data integrity in always-on deployments. The 32 PCIe Gen 3 lanes allow dense I/O configurations, making it suitable for systems that need many NVMe drives or high-speed network interfaces.

For workstation use, the 16 threads can accelerate compilation, rendering, and scientific computation, though the 3.10 GHz boost limits single-thread-heavy tasks like legacy CAD or lightly threaded audio work. For office productivity, the 3255 is overkill in core count but the 55 W TDP means it can run in a compact, quiet chassis; however, the lack of integrated graphics on the CPU (only a chipset feature on certain motherboards) means a discrete GPU or a board with onboard graphics is required for any display output. Gaming is not a primary use case — the embedded socket, server focus, and absent iGPU make it a poor fit for consumer gaming rigs.

The data suggests the ideal buyer is an embedded systems integrator building a fixed-function server appliance that needs reliable ECC memory, decent multi-thread compute, and a moderate 32-lane PCIe fabric. The active production status means the part is still orderable for new designs, and the February 2018 release means it has a mature ecosystem of motherboards and BIOS support.

FAQ

Power and Thermals

The TDP is 55 W, a modest figure for an 8-core, 16-thread processor. This places the 3255 in a low-power tier relative to typical server CPUs, which often draw significantly more. The 14 nm process from GlobalFoundries and the 4,800 million transistor count on a 213 mm² die contribute to this efficiency. A 55 W TDP implies that a capable air cooler is sufficient — no exotic liquid cooling or large radiator is required.

The embedded form factor (BGA SP4r2) means thermal solutions are typically designed into the system chassis, often with passive heatsinks in fanless network appliances. The base clock of 2.50 GHz and boost of 3.10 GHz suggest the thermal headroom is allocated to sustained all-core operation rather than short bursts. For system integrators, the 55 W figure allows compact enclosures with modest airflow, which is a key advantage in embedded deployments where space and noise are constrained. The data does not provide a separate thermal specification beyond TDP, so the cooling tier is best inferred from the wattage: a low-profile active cooler or a well-ventilated passive heatsink would suffice. This power profile is a core selling point for the 3255, enabling dense server installations where per-socket power budgets are tight.
