Intel Xeon Bronze 3106

The Intel Xeon Bronze 3106 is an 8-core, 8-thread server processor built on the 14 nm Skylake-SP architecture. With a base clock of 2.10 GHz and a boost clock of 3.00 GHz, it targets entry-level server and workstation duties. Its benchmark scores place it in the 38th percentile of all CPUs, indicating a part that performs near the middle of the pack but lacks the multi-threading and higher core counts common in its segment.

How It Compares

Against the Intel Core i7-2700K, the Xeon Bronze 3106 trails by a razor-thin margin of 0.1% in average benchmark score. The i7-2700K, a much older consumer part, achieves an average score of 1424 versus the Xeon's 1423. This effectively makes the two processors performance equals in mixed workloads, despite the Xeon's newer architecture and server-oriented feature set.

The Intel Core i7-3820 sits just 0.1% behind the Xeon Bronze 3106, with an average score of 1422. This delta is within run-to-run variance, meaning the two parts are statistically indistinguishable in overall throughput. The Xeon's advantage lies not in raw speed but in platform features like ECC memory support, which the i7-3820 lacks.

Compared to the AMD Opteron 4274 HE, the Xeon Bronze 3106 leads by 0.2%. The Opteron posts an average score of 1420, making it the closest competitor in this group. The Xeon's 8 cores at 2.10 GHz base outperform the Opteron's similar core count, though the margin is small enough that workload-specific behavior could reverse the order.

The Intel Core i5-4570S is the only rival that clearly outperforms the Xeon Bronze 3106, beating it by 0.4% with an average score of 1429. This quad-core consumer chip benefits from higher per-core clocks, which helps in lightly threaded tasks. The Xeon's 8 threads still give it an edge in highly parallel workloads, but the i5-4570S wins in overall average performance.

Power and Thermals

The Xeon Bronze 3106 carries a TDP of 85 watts, a modest figure for a server processor with 8 physical cores. This TDP class places it well below many other Skylake-SP parts, which often exceed 100 watts. The implication is that a capable air cooler or a basic server heatsink is sufficient to maintain stable operation under sustained load.

The 14 nm process node and 8,000 million transistors contribute to this efficiency. The 85 W envelope allows for deployment in dense chassis where thermal headroom is limited, or in systems that prioritize low noise over maximum performance. Data suggests that the processor will not require exotic cooling solutions, making it suitable for standard 1U or 2U server configurations.

In a benchmark context, the 85 W TDP means the chip can sustain its 3.00 GHz boost clock on a single core without significant thermal throttling. Multi-core workloads will likely see clocks settle near the 2.10 GHz base, but the thermal design keeps the system within predictable power budgets. For workstation users, this translates to a processor that runs cool under typical rendering or compilation loads.

Who Should Consider It

For single-threaded office workloads, the Xeon Bronze 3106 delivers a Cinebench R23 single-core score of 694. This is sufficient for everyday productivity tasks like document editing, spreadsheet work, and web browsing, though it will not feel snappy compared to modern consumer chips. The 3.00 GHz boost clock helps, but the aging Skylake architecture limits peak responsiveness.

Multi-threaded content creation is where this processor shows its strength. The Cinebench R23 multi-core score of 4920 indicates solid performance for video encoding, 3D rendering, and batch photo processing. The 8 cores and 8 threads handle parallel workloads efficiently, and the 11 MB shared L3 cache reduces memory latency in threaded applications.

Server and virtualization environments are the primary target. The 85 W TDP and ECC memory support make it a reliable choice for entry-level database servers, file servers, or virtualization hosts running a handful of VMs. The Cinebench R20 multi-core score of 2066 suggests it can handle moderate concurrent workloads without choking, though heavy virtualization would demand more cores.

FAQ

Q: How does the Xeon Bronze 3106 perform in single-core workloads?

A: It scores 694 in Cinebench R23 single-core and 291 in Cinebench R20 single-core. This places it at the level of a mid-range consumer processor from several generations ago, adequate for basic tasks but not for high-frequency gaming or interactive 3D work.

Q: Does the processor support ECC memory?

A: Yes, ECC memory support is enabled. This makes it suitable for servers and workstations where data integrity is critical, as it can detect and correct memory errors without crashing the system.

Q: What is the memory type supported?

A: The Xeon Bronze 3106 supports DDR4 memory. The fact pack does not specify a memory bus width or bandwidth, but the DDR4 support combined with ECC capability covers typical server requirements.

Q: How many cores and threads does it have?

A: It has 8 cores and 8 threads. There is no Hyper-Threading support, so each core handles exactly one thread, which limits its performance in heavily threaded applications compared to processors with similar core counts but higher thread counts.

Q: What socket does it use?

A: It uses the Intel Socket 3647, which is the LGA 3647 platform designed for Skylake-SP Xeon processors. This socket is exclusive to server and workstation motherboards, not consumer desktop boards.

Q: Is the processor unlocked for overclocking?

A: No, the multiplier is locked. The base clock of 2.10 GHz and boost clock of 3.00 GHz are fixed, so users cannot manually adjust the multiplier to push beyond 3.00 GHz.

Benchmark Performance

The average benchmark score of 1423 places the Xeon Bronze 3106 at the 38th percentile of all CPUs. This is a modest position, reflecting its status as an entry-level server chip. The nearest rival, the Intel Core i7-2700K, scores 1424, a delta of -0.1% — meaning the Xeon is effectively tied with a consumer processor released five years earlier.

In Cinebench R15, the Xeon scores 495 in multi-core and 69 in single-core. The multi-core figure indicates that the 8 cores scale reasonably well, but the single-core score of 69 is low, confirming that per-thread performance is a bottleneck. The i7-2700K, by comparison, achieves a similar average score despite having only 4 cores and 8 threads, highlighting the Xeon's weaker single-thread capability.

Moving to Cinebench R20, the Xeon posts 2066 multi-core and 291 single-core. The multi-core score is roughly 4.2 times the single-core score, showing good scaling across its 8 cores. The Intel Core i5-4570S, which leads the rival group by 0.4%, likely outperforms the Xeon in single-core but falls behind in multi-core due to its 4-core/4-thread configuration.

The Cinebench R23 results show 4920 multi-core and 694 single-core. The multi-core score is about 7.1 times the single-core score, which is close to the theoretical maximum of 8 for a chip without SMT. This indicates that the processor achieves near-linear scaling in well-parallelized workloads, a positive sign for rendering or scientific computing tasks.

The delta percentages against rivals are all within ±0.5%, meaning the Xeon Bronze 3106 is part of a tightly clustered performance tier. The AMD Opteron 4274 HE trails by 0.2%, while the Intel Core i7-3820 trails by 0.1%. The i7-2700K leads by 0.1%, and the i5-4570S leads by 0.4%. This suggests that in real-world mixed workloads, the choice between these parts would be dictated by platform features rather than raw speed.

Platform and Compatibility

The Xeon Bronze 3106 uses the Intel Socket 3647, a platform designed for Skylake-SP Xeon processors. This socket supports DDR4 memory with ECC capability, making it suitable for reliable server operation. The fact pack does not specify memory channels or maximum capacity, but the DDR4 support covers standard server configurations.

The processor is built on the Skylake-SP architecture with a 14 nm process node, containing 8,000 million transistors. It has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 11 MB of shared L3 cache. This cache hierarchy is typical for Skylake-SP, providing adequate bandwidth for the 8-core design.

PCIe support is not specified in the fact pack, so the exact lane count and version cannot be stated. However, Socket 3647 platforms generally offer ample PCIe lanes for server peripherals like network cards, storage controllers, and GPUs. The upgrade path is limited to other Socket 3647 Xeon processors, though the fact pack does not list which specific models are compatible.

The market segment is listed as Server/Workstation, confirming that this is not a consumer desktop part. The lack of integrated graphics means a discrete GPU is required for any display output, which is standard for server processors. The release date is July 2017, placing it in the first wave of Skylake-SP Xeon parts, and the production status is not specified, so availability is unknown.
