Intel Atom N475

The Intel Atom N475 is a single-core, dual-thread mobile processor from Intel’s Pineview generation, built on a 45 nm process. Released in mid-2010, this end-of-life chip targets low-power, entry-level mobile computing, with a 7 W TDP and integrated graphics available only on certain motherboards as a chipset feature. The benchmark data for this processor is minimal, with no recorded scores and a 50th percentile ranking against all CPUs, indicating it sits at the median of the performance distribution purely by position, not by demonstrated capability.

Benchmark Performance

The FACT PACK reports an average benchmark score of 0 and no entries in the benchmarks array, meaning there are no direct performance measurements to analyze. Consequently, the nearestRivals list is empty, providing no comparative deltaPct values or rival names for reference. The percentileVsAllCpus field shows a value of 50, which places this processor at the midpoint of the cumulative CPU performance distribution. However, this percentile is based on the absence of data rather than on measured scores, so it should be interpreted as a placeholder rather than a meaningful performance indicator. Without benchmark scores, the data cannot substantiate any percentage-based comparisons to other processors. The absence of rival data means no exact deltas can be cited, and any quantitative assessment of its speed relative to contemporaries is impossible from the provided facts. The only verifiable performance-related figures are the base clock of 1834.00 MHz, the single core, and the dual threads, which suggest a very modest computational throughput. In practical terms, benchmark results indicate that this processor is not designed for high-performance tasks, and its ranking at the 50th percentile among all CPUs likely reflects its historical position in a broad catalog rather than any competitive edge.

Who Should Consider It

Given the lack of benchmark scores, workload recommendations must be inferred from the architectural characteristics. The single core and two threads, combined with a 1.834 GHz base clock, indicate that this processor is suited for basic, sequential tasks. For office applications such as word processing, spreadsheet editing, and email, the Atom N475 could handle light usage, but the data shows no margin for multitasking or demanding software. Gaming is not a viable use case, as the integrated graphics are only a chipset feature on certain motherboards, and the single core would struggle with modern game engines. Content creation, including video editing or 3D rendering, is entirely out of scope, as these workloads require multiple cores and higher clock speeds. The processor’s market segment is Mobile, and its end-of-life status suggests it was intended for netbooks or low-cost portable devices. Users who need a basic web browsing or document editing machine might find it adequate, but the absence of any benchmark scores means there is no evidence of even modest performance. The 7 W TDP does imply very low power draw, which could extend battery life in a portable device, but this is a power specification, not a performance one. In summary, the Atom N475 is only suitable for the lightest computing tasks, and even then, the data provides no confirmation of usability.

Power and Thermals

The TDP for the Intel Atom N475 is 7 W, which classifies it in the ultra-low-power segment. This figure is the only thermal or power number in the FACT PACK, and it implies that a basic passive or small active cooling solution would be sufficient. A 7 W TDP is typical for netbook-class processors, allowing for fanless designs in some chassis or very small fans in others. The 45 nm process node and 123 million transistors on a 66 mm² die size contribute to this low power envelope, but the data does not specify actual thermal output or cooling requirements beyond the TDP class. The lack of a boost clock means the processor runs at a fixed 1834.00 MHz, which prevents transient power spikes, further simplifying thermal management. In a mobile context, this low TDP would enable longer battery operation, but no battery life figures are provided. For cooling tier, the 7 W TDP suggests that a small heatsink or a low-profile cooler would be adequate, and no liquid cooling or high-airflow solutions are necessary. The production status is end-of-life, so thermal solutions are no longer actively developed for this chip, but the low TDP ensures that any existing cooler from that era would suffice.

Platform and Compatibility

The Intel Atom N475 uses the Intel BGA 559 socket, which is a ball-grid array package designed for soldered installation on motherboards. This socket is specific to the Pineview generation, and the processor is not upgradeable in the traditional sense, as it is not socketed for user replacement. Memory support includes DDR2 and DDR3, but the FACT PACK does not specify the bus width, maximum capacity, or supported speeds, so the memory subsystem details remain qualitative. ECC memory is not supported, which limits its use in error-sensitive environments. The PCIe field is null, meaning no PCI Express lanes or versions are documented, so expansion capabilities are undefined. Integrated graphics are listed as “On certain motherboards (Chipset feature),” which indicates that the graphics functionality is not part of the processor die but rather depends on the motherboard’s chipset implementation. The upgrade path is essentially nonexistent due to the BGA socket and end-of-life status; users cannot swap this processor for a faster model. The architecture is Atom, codenamed Pineview, which is a single-generation design, and the 45 nm process node is outdated. For platform compatibility, any motherboard with the Intel BGA 559 socket and supporting DDR2 or DDR3 memory would be required, but the lack of PCIe data means add-in cards may not be supported. The part number is SLBX5, which helps identify specific units, but this does not affect compatibility.

FAQ

Q: What is the base clock speed of the Intel Atom N475?

A: The base clock is 1834.00 MHz, with no boost clock available, so it operates at this fixed frequency.

Q: Does this processor support ECC memory?

A: No, ECC memory is not supported, as indicated by the false value in the eccMemory field.

Q: How many cores and threads does the Atom N475 have?

A: It has 1 core and 2 threads, which means it can handle two concurrent threads via hyper-threading.

Q: What memory types are compatible with this processor?

A: The memory support includes DDR2 and DDR3, but no specific speeds or capacities are provided.

Q: Is the integrated graphics part of the processor?

A: No, integrated graphics are available only on certain motherboards as a chipset feature, not on the processor itself.

Q: What is the TDP of the Atom N475?

A: The TDP is 7 W, classifying it as an ultra-low-power mobile processor.

Single-Thread vs Multi-Thread Behavior

The Intel Atom N475 has a single physical core with two threads via hyper-threading, which means its multi-thread capability is limited to one core processing two threads. The base clock of 1834.00 MHz applies to all operations, and there is no boost clock to dynamically raise frequency for single-thread bursts. For single-threaded workloads, the processor executes one instruction stream at a time, and the lack of boost means it cannot temporarily increase speed to improve responsiveness. This makes single-thread performance directly tied to the 1834.00 MHz clock, which is modest by modern standards. For multi-threaded workloads, the two threads can share the single core’s execution resources, but this does not double throughput; it only improves efficiency when one thread is stalled. The cache configuration includes 56 KB of L1 per core and 512 KB of L2 per core, which are small and limit the amount of data that can be held close to the execution units. In real workloads, single-thread tasks like opening applications or loading web pages will run at the fixed clock speed, while multi-thread tasks like background updates may see slight gains from the second thread. However, the data shows no benchmark scores to quantify this behavior, so any performance split is speculative. The 50th percentile ranking, based on zero scores, offers no insight into single-thread versus multi-thread strengths. Given the architecture, this processor is better suited to single-thread, low-intensity tasks, but the absence of measured data prevents a definitive conclusion. The two threads might help with basic multitasking, but the single core remains a bottleneck for any parallel workload.
