Intel Pentium SU4100

The Intel Pentium SU4100 is a 45nm, dual-core mobile processor from the Core 2 era, built on the Penryn architecture. It is an end-of-life product, and the benchmark data indicates it holds a 50th percentile position among all CPUs, reflecting its historical mid-pack standing for its time.

Platform and Compatibility

The Pentium SU4100 uses the Intel BGA 956 socket, which is a surface-mounted design. This means the processor is soldered directly to the motherboard, a common approach for ultra-portable laptops where space is at a premium and user-level upgrades are not intended. The platform is based on the Core 2 architecture with the Penryn codename, forming part of the Pentium Dual-Core generation.

Memory support is limited to DDR3 RAM, with no support for ECC memory. The integrated graphics are not a core feature of the CPU itself but are provided as a chipset feature, meaning they are available "on certain motherboards" that include a compatible graphics controller. This design separates the graphics processing from the CPU die, a typical arrangement for the era.

The processor does not feature a PCIe specification in the available data, and its upgrade path is effectively non-existent. Because the chip is permanently attached to the BGA 956 socket, replacing the CPU is not feasible. Any system upgrade would require a full motherboard replacement, which is impractical for the mobile market segment this processor targets. The data confirms the production status is "End-of-life," signaling that no new platforms are being developed for this socket.

Power and Thermals

The Pentium SU4100 has a thermal design power (TDP) of 10 watts. This classifies it as an ultra-low-voltage processor, specifically engineered for thin and light laptops where power efficiency is the primary concern. A 10-watt TDP is exceptionally modest, placing it in the same thermal envelope as passively cooled designs or systems with very small, low-speed fans.

This low power draw implies a specific cooling tier: a basic, low-profile heatsink is sufficient. The data does not support the need for any active cooling beyond a small fan, nor does it suggest the use of high-end vapor chambers or heat pipes. The 10-watt figure directly translates to minimal heat generation, which allows system designers to prioritize portability and battery life over thermal headroom. The architecture is built on a 45nm process node, which was a mature technology at the time, further reinforcing the low-power profile. The processor is not multiplier unlocked, so there is no user-facing overclocking headroom to consider in thermal planning.

Benchmark Performance

The benchmark scores for the Pentium SU4100 are sparse, but the available data provides a clear relative position. The average benchmark score is 0, which is a normalized baseline. More importantly, the processor sits at the 50th percentile of all CPUs. This percentile is a crucial indicator: it means the SU4100 performs better than half of all processors in the database and worse than the other half.

This 50th percentile ranking must be interpreted within its historical context. The SU4100 is a dual-core, dual-thread processor with a base clock of 1300.00 MHz and 2 MB of L2 cache. It has no boost clock, meaning its operating frequency is fixed. The lack of a boost clock is a significant performance limiter in single-threaded workloads, where the CPU cannot dynamically increase its speed to handle short bursts of activity. The 64 KB of L1 cache is also minimal by modern standards.

The data shows no nearest rivals and no comparative delta percentages. This absence of direct comparison points makes it difficult to state exact percentage advantages or disadvantages against specific competitors. However, the 50th percentile position is a strong statistical statement. It indicates that while the processor is not a performance leader, it is also not a bottom-tier part. The score reflects a balanced, if unspectacular, level of throughput for its generation. In practical terms, the SU4100's performance is sufficient for basic tasks that do not require sustained high-frequency operation, but it lacks the headroom for demanding applications.

How It Compares

The nearestRivals list in the data is empty, which precludes a direct rival-by-rival analysis with specific percentage deltas. The only comparative data available is the global percentile ranking.

Against the broader field of all CPUs in the database, the SU4100's 50th percentile placement is its primary comparative metric. This suggests it sits squarely in the middle of the performance distribution, but this is a historical artifact. Modern processors, even entry-level ones, have far higher core counts and clock speeds. The SU4100's fixed 1300 MHz clock and dual-thread configuration place it well below contemporary standards, but the 50th percentile means that the database contains an equal number of less-capable parts, likely older or more specialized low-power chips.

Without specific rival data, the comparison is limited to this global view. The processor's performance is defined by its own specifications: a 10-watt TDP, a 1300 MHz base clock, and 2 MB of L2 cache. These figures, combined with the 50th percentile score, paint a picture of a chip that was designed for efficiency rather than speed. It does not compete on raw performance, but it does hold a defensible position in its own low-power niche.

Who Should Consider It

The Pentium SU4100 is a historical product, and its suitability is entirely workload-dependent, as evidenced by its benchmark scores and specifications. The data suggests it is not appropriate for modern gaming or content creation. The dual-core, dual-thread design with a fixed 1300 MHz clock lacks the multi-threaded throughput and single-core burst speed required for these tasks. The absence of a boost clock means that even light gaming titles that rely on rapid frequency scaling will struggle.

The processor is more aligned with basic office productivity and general web browsing. Its 10-watt TDP and 45nm process make it an excellent fit for fanless or near-silent systems where the workload is light and intermittent. Word processing, spreadsheet work, and email are within its capabilities, as these tasks do not require sustained high performance. The 2 MB of L2 cache helps with these smaller, more frequent data operations.

For users considering a legacy system with this chip, the recommendation is clear: it is only suitable for secondary or dedicated tasks like a lightweight file server or a basic text-entry terminal. Its 50th percentile ranking confirms that it is not a performance outlier, but its efficiency is its key attribute. The lack of ECC support and the soldered BGA 956 socket further cement its role as a component for low-cost, low-power consumer laptops, not for professional workstations or enthusiast builds.
