Intel Atom C5115

The Intel Atom C5115 is a 4-core, 4-thread server processor built on the 10nm Parker Ridge platform, targeting low-power network and storage appliances. As a Tremont-class Atom part, it prioritizes efficiency and deterministic throughput over raw compute muscle, making its benchmark profile distinctly different from consumer desktop chips.

Benchmark Performance

The Intel Atom C5115 does not have any benchmark scores recorded in the database, and its average benchmark score is reported as 0. This places it at the 50th percentile of all CPUs tracked, which reflects a position in the middle of the distribution—but this is a statistical artifact of the zero-score entry rather than an indication of real-world mid-pack performance. Without a score, there are no direct performance deltas to cite against rivals, and no nearest rivals have been defined for comparison.

What the data does show is a processor with 4 cores and 4 threads running at a base clock of 2.80 GHz. There is no boost clock listed, meaning the chip operates at a fixed frequency under load. In a server context, this translates to predictable, consistent performance for single-threaded control-plane tasks, but it also caps the multi-threaded ceiling. A 4-thread part at 2.80 GHz will handle modest concurrent workloads, but it will not compete with higher-core-count Xeons or even mid-range desktop chips in heavily threaded scenarios. The absence of a boost clock also means there is no headroom for transient performance spikes; the chip sustains its rated speed or thermal management will throttle it.

The lack of benchmark data makes it impossible to state a percentage advantage or deficit against any named competitor. The 50th percentile ranking is the only quantifiable comparison point, and even that must be treated cautiously. In practical terms, the C5115’s performance envelope is defined by its core count, thread count, and clock speed: it is a single-socket, low-power part designed for specific tasks like packet processing, simple database lookups, or as a management processor, not for number-crunching or rendering.

Who Should Consider It

Given its 4-core/4-thread configuration, 43W TDP, and server/workstation market segment, the Intel Atom C5115 is best suited for workloads that prioritize low power consumption and deterministic latency over raw throughput.

• Network appliances: Firewalls, routers, and VPN concentrators typically run single-threaded or lightly threaded packet-forwarding code. The C5115’s fixed 2.80 GHz clock and 4 threads are adequate for these tasks, and the 43W TDP makes it easy to cool in a compact chassis.
• Storage controllers: Entry-level NAS or SAN controllers that manage a handful of drives do not need many cores. The C5115 can handle file-serving protocols and RAID calculations without excessive power draw, and its ECC memory support (noted in the spec sheet) is a plus for data integrity.
• Industrial and embedded systems: Parker Ridge is a server-class Atom, so it fits into long-lifecycle products where reliability and a fixed instruction set matter more than peak speed. The active production status and BGA 2106 socket suggest it is intended for board-level integration rather than end-user upgrades.
• Not for gaming or content creation: With only 4 threads and no integrated graphics, the C5115 is unsuitable for gaming (discrete GPU required) and will struggle with video editing or 3D rendering, which scale with core counts and boost clocks. Office productivity would work but would feel sluggish compared to even low-end consumer chips with higher clocks and more threads.

The launch MSRP is $239. This positions it as a specialized component for OEMs and system integrators, not a general-purpose desktop purchase.

Power and Thermals

The Intel Atom C5115 carries a 43W TDP. This is a low-power classification for a server part, comparable to ultra-mobile processors rather than desktop or rack-server CPUs that routinely exceed 65W. The 10nm process node (Intel’s own foundry) contributes to this efficiency, allowing the chip to deliver its 2.80 GHz base clock without a large thermal envelope.

Cooling requirements are modest. A passive heatsink or a small, low-profile active cooler is sufficient for most chassis designs. The 43W figure means no liquid cooling or high-end air tower is necessary; in fact, such solutions would be overkill. The lack of a boost clock reduces thermal spikes—the chip draws steady power under load, which simplifies thermal design for fanless or low-noise environments. For system integrators, this TDP class allows for dense deployments in 1U servers or fanless industrial PCs where airflow is limited. There is no unlocked multiplier, so overclocking is not an option, which further reinforces the stable, low-power operating profile.

FAQ

Q: What is the base clock speed of the Intel Atom C5115?

A: The base clock is 2.80 GHz. There is no boost clock listed, so this is the maximum sustained frequency.

Q: Does the C5115 support ECC memory?

A: Yes, ECC memory is marked as supported. The memory bus is dual-channel DDR4 with a peak bandwidth of 46.9 GB/s.

Q: What socket does the C5115 use?

A: It uses Intel BGA 2106, which is a ball-grid-array package. This means the CPU is soldered to the motherboard and is not user-replaceable or upgradeable.

Q: How many PCIe lanes does it provide?

A: The CPU provides 16 PCIe Gen 3 lanes. This is the total from the CPU itself; chipset-provided lanes are not included in this figure.

Q: Is the C5115 good for gaming?

A: No. It has no integrated graphics (N/A) and only 4 threads, so a discrete GPU would be mandatory, and the CPU would bottleneck modern games due to its low thread count and lack of boost clock.

Q: When was the C5115 released?

A: The release date is listed as June 5, 2022, and the production status is currently active.

Single-Thread vs Multi-Thread Behavior

The Intel Atom C5115 has 4 cores and 4 threads—no Hyper-Threading or equivalent. This means it can execute exactly 4 threads simultaneously. Its base clock of 2.80 GHz is moderate, and the absence of a boost clock means it cannot temporarily boost frequency for short single-threaded bursts.

In single-threaded tasks, the C5115 will perform adequately for basic operations: handling a network packet, processing a system call, or running a simple script. The 2.80 GHz clock is respectable for an Atom, and the Tremont architecture (noted in the generation field) is designed for efficient single-thread execution in low-power envelopes. However, it will be slower than any modern desktop CPU with a 4.0+ GHz boost clock, since those chips can ramp up to higher frequencies on one core.

In multi-threaded tasks, the C5115’s limitation is clear. With only 4 threads, it cannot scale to handle parallel workloads like database queries with many concurrent connections, video encoding, or compile jobs. The L2 cache is 4.5 MB per module, which is shared between cores in a module, but the total cache footprint is small compared to server CPUs with 30+ MB of L3. The data shows no L3 cache at all, which further constrains multi-threaded performance in cache-sensitive workloads. For a server chip, the C5115 is best treated as a single-thread-first processor: it will excel at managing a single stream of I/O or control functions but will bottleneck if you throw multiple heavy threads at it. The dual-channel memory bus with 46.9 GB/s bandwidth is sufficient for 4 threads, so memory is not the primary constraint; the core count is.

Platform and Compatibility

The Intel Atom C5115 is built for the Parker Ridge platform, using the Intel BGA 2106 socket. This is a soldered, non-upgradeable package, meaning the CPU is permanently attached to the motherboard. The production status is active, and the part number is SRL41.

Memory support is DDR4 in a dual-channel configuration, with a maximum bandwidth of 46.9 GB/s. ECC is supported, which is critical for server reliability—it can detect and correct memory errors without crashing the system. The memory controller is integrated into the CPU, so the memory speed is tied to the chip’s capabilities, but the spec sheet does not list a maximum memory speed, only the bandwidth figure.

PCIe support is Gen 3 with 16 lanes from the CPU. This is a fixed allocation; there is no mention of additional lanes from a chipset, so the 16 lanes must cover all I/O devices—network controllers, storage adapters, and any expansion slots. For a typical network appliance, 16 Gen 3 lanes are sufficient for a couple of 10GbE NICs or a RAID controller. The integrated graphics is listed as N/A, so a discrete GPU or a BMC (baseboard management controller) is required for display output. The chip does not have an unlocked multiplier, so there is no overclocking capability.

Upgrade path is effectively non-existent because of the BGA socket. Once the board is designed around the C5115, the CPU cannot be swapped for a higher-end part. This is typical for Atom-class server chips, which are sold as complete boards or systems rather than boxed processors. The market segment is explicitly Server/Workstation, confirming that this is not a consumer desktop part.

How It Compares

As of the data provided, the Intel Atom C5115 has no nearest rivals listed in the benchmark database. This means there are no direct comparison points with named competitors, and no deltaPct values are available to quantify performance differences.

The absence of rival data is notable. In the broader CPU market, the C5115 would sit in a niche between low-end Pentium/Celeron parts and entry-level Xeons, but the database does not provide those comparisons. Without a nearestRivals array, it is impossible to state how it performs relative to an AMD EPYC, an Intel Xeon D, or even a desktop Core i3. The only metric available is the 50th percentile ranking, which is ambiguous given the zero benchmark score.

Qualitatively, the C5115’s 4-core/4-thread configuration and 43W TDP place it in the Atom family’s server-oriented segment, which historically targets networking and storage rather than compute-intensive jobs. Rivals, if they were listed, would likely include other low-power Atoms or ARM-based server SoCs, but no such data is in the pack. For now, the C5115 must be evaluated on its own specifications: a fixed 2.80 GHz clock, 16 PCIe Gen 3 lanes, and dual-channel DDR4 with ECC. Its performance will be dictated by those constraints, and any comparison to other CPUs would require external benchmark data that is not present in this record.
