Intel Atom S1240

The Intel Atom S1240 is a dual-core server processor from the Centerton family, built on a 32 nm process and designed for the Server/Workstation market segment. With a base clock of 1600.00 MHz and no boost clock capability, this chip is positioned at the entry level of Intel's Atom lineup, targeting workloads where power efficiency trumps raw performance. The data indicates a 50th percentile standing against all CPUs, placing it squarely in the middle of the performance distribution, though its average benchmark score of 0 suggests it is not intended for demanding computational tasks.

Who Should Consider It

The S1240 is a specialized part for environments where low power draw is the primary concern and computational demands are minimal. The 2-core, 4-thread configuration with a 1600.00 MHz base clock makes it suitable for lightweight, always-on server roles such as dedicated network appliances, simple file sharing, or basic monitoring tasks. The thread count doubles the core count, allowing the processor to handle four concurrent threads, which is beneficial for small-scale multi-tasking but offers no advantage for single-threaded heavy lifting.

For gaming, this processor is not a viable option. The lack of a boost clock and the modest 1600.00 MHz frequency place it far below the performance threshold required for modern game logic, and the integrated graphics are listed only as "On certain motherboards (Chipset feature)", indicating no reliable on-chip GPU solution. Creation workloads, such as video editing or 3D rendering, are equally unsuitable, as these tasks rely heavily on multi-core scaling and high memory bandwidth, neither of which is a strength of this dual-core Atom.

Office productivity is a marginal fit. Basic word processing, spreadsheet work, and web browsing on a single user basis could function, but the processor's low clock speed will result in noticeable lag in modern, JavaScript-heavy web applications. The 50th percentile ranking among all CPUs is misleading here, as that figure is skewed by the inclusion of many low-power embedded parts; in absolute terms, the S1240 is a low-performance chip. The most appropriate use case is as a controller or management processor in a larger system, where its 6 W TDP ensures minimal thermal and power impact.

Power and Thermals

The S1240 has a TDP of just 6 watts, placing it in the ultra-low-power class of processors. This figure is the defining characteristic of the chip, as it allows passive cooling solutions or the smallest active coolers in most chassis. The data shows that a simple heatsink is sufficient to manage thermals; there is no need for liquid cooling or large tower air coolers. The 32 nm process node contributes to this efficiency, though the lack of a boost clock means the power draw remains constant at its base state under load.

This low TDP has practical implications for system design. It enables fanless operation in compact enclosures, which is ideal for silent home servers or industrial networking equipment. The thermal output of 6 W is negligible in a standard ATX case, but in dense blade servers or small form-factor devices, it allows for high component density without airflow concerns. Benchmark data does not include thermal throttling metrics, but the absence of a boost clock suggests the processor runs at a fixed frequency, minimizing thermal variance. Cooling tier is effectively "passive or low-profile active", making the S1240 extremely flexible for chassis design.

Platform and Compatibility

The S1240 uses the Intel BGA 1283 socket, meaning it is soldered to the motherboard and not user-replaceable. This socket choice ties the processor to a specific platform, and the architecture is listed as "Atom" with the codename "Centerton". Memory support is limited to DDR3, and the system does not support ECC memory, which is a notable omission for a server-focused part, as error-correcting code is often critical for data integrity in long-running workloads.

There is no listed PCIe support in the data, which suggests that expansion capability is either minimal or handled through the chipset rather than direct CPU lanes. The integrated graphics are described as "On certain motherboards (Chipset feature)", indicating that display output is not a guaranteed CPU function but rather depends on the specific motherboard implementation. The part number is SLK2J, and it was released on 2012-12-10, making it a legacy product. Upgrade path is essentially non-existent; since the CPU is BGA-mounted, any upgrade would require a full motherboard replacement. For new builds, this platform is outdated, but for existing Centerton-based systems, the S1240 is a fixed component. The memory controller supports DDR3, but without a memory bus width or bandwidth figure, the data does not indicate dual-channel or single-channel operation.

How It Compares

The FACT PACK lists no nearest rivals for the S1240, which means there are no direct comparative scores or deltaPct values to reference. In the absence of competitor data, the analysis must rely on the processor's own metrics. The 50th percentile vs all CPUs indicates that half of all processors in the database score higher and half score lower, but this is a broad ranking that includes vastly different market segments.

Without rival scores, it is impossible to state a percentage advantage or deficit against specific models. The data does show a 2-core, 4-thread layout, which is typical of entry-level parts, but no comparison can be drawn to other Atom variants or competing Celeron or Pentium chips. The absence of benchmarks (empty array) further limits comparative analysis. In this context, the S1240 stands alone in the dataset, and any claims about its relative performance to other specific CPUs cannot be substantiated from the provided information.

Single-Thread vs Multi-Thread Behavior

The S1240 has 2 physical cores and 4 threads, achieved through Hyper-Threading or a similar technology, as implied by the thread-to-core ratio. The base clock of 1600.00 MHz applies to all cores, and there is no boost clock, meaning the frequency is static under all conditions. This design favors multi-threaded workloads that can utilize all four threads simultaneously, as the processor can spread the load across the available execution units.

For single-threaded performance, the 1600.00 MHz clock is the sole determinant, and it is low by modern standards. A single-threaded task will run at this fixed frequency, and the lack of turbo means there is no headroom to accelerate a single core. This results in sluggish response for applications that are not well-parallelized, such as legacy software or certain scripting languages. Conversely, multi-threaded workloads that can scale across four threads will see a benefit, but the absolute throughput remains limited by the low clock speed and the Atom architecture's modest instructions-per-clock. The L2 cache is 512 KB per core, which provides a reasonable buffer for working sets, but the L1 is only 56 KB per core, which is small. The data indicates that the processor is more balanced for multi-threaded tasks than single-threaded ones, but the overall performance envelope is low.
