Intel Core i3-350M

The Intel Core i3-350M is a mobile processor from the Arrandale generation, built on Intel's Westmere architecture and a 32 nm process node. It integrates two physical cores with four threads via Hyper-Threading, a base clock of 2.27 GHz, and a 35 W TDP. The data places this chip at the 3rd percentile of all CPUs, indicating it operates at the extreme low end of modern performance expectations, yet its benchmark scores reveal a specific profile suited to legacy or low-power workloads.

Benchmark Performance

The Core i3-350M's average benchmark score across all tests is 353, which places it in a tight cluster with several desktop-era Athlon II and Pentium parts. The nearest rival, the AMD Athlon II X2 255, posts an identical average score of 353, yielding a delta of -0.1% — effectively a statistical tie. The Intel Pentium E6700 and AMD Athlon II X2 240e both score 355, putting the i3-350M 0.5% and 0.6% behind respectively. Conversely, the AMD Athlon II X2 250e scores 351, meaning the i3-350M is 0.6% ahead. These deltas, all under 1%, demonstrate that the i3-350M delivers performance indistinguishable from its closest competitors, despite architectural differences.

Looking at specific workload metrics, the Cinebench R23 multi-core score of 918 is the strongest result in the synthetic suite. In contrast, the single-core score of 129 is much lower, highlighting the chip's reliance on multi-threading to achieve any competitive standing. The Geekbench results reinforce this: a multi-core score of 596 versus a single-core score of 295 shows a 2.02x scaling factor, which is close to the theoretical 2x gain from two physical cores, but the absolute numbers are low. For context, the Cinebench R20 multi-core score of 385 and single-core score of 54 illustrate that the i3-350M struggles with modern rendering tasks; the multi-core score is roughly 7.1x higher than single-core, but both are dwarfed by contemporary desktop parts.

The deltaPct values against nearest rivals are all within ±0.6%, which means the i3-350M offers no meaningful advantage or disadvantage in raw throughput versus those specific chips. However, the 3rd percentile ranking across all CPUs is the more telling figure: 97% of processors in the database outperform it. This is not a chip for competitive benchmarking; it is a chip for basic functionality. The Cinebench R15 multi-core score of 92 further confirms this, as even entry-level mobile processors from a decade later would exceed that number by multiple factors.

Power and Thermals

The TDP is rated at 35 W, a modest figure for a dual-core mobile part from 2010. This power envelope classifies the i3-350M as a low-power processor, suitable for thin-and-light laptops or compact all-in-one systems of its era. Because the boost clock is null, the chip runs at a constant 2.27 GHz, meaning power draw remains predictable under sustained load. The 32 nm process node helps keep thermals manageable, but the die size of 81 mm² with 382 million transistors indicates a relatively dense layout for the time.

Cooling requirements are minimal. A simple passive heatsink with a small fan, or even a well-ventilated chassis relying on natural convection, would suffice for most workloads. The absence of a boost clock means there is no thermal headroom to manage for short bursts; the chip operates at a fixed frequency, so cooling solutions only need to dissipate the steady-state 35 W. For a modern user, this implies that any aftermarket cooler designed for low-TDP sockets would be overkill. The integrated graphics are a chipset feature available on certain motherboards, which adds no additional thermal burden to the CPU die itself.

Who Should Consider It

This processor is not suitable for gaming, modern content creation, or any task that leverages current multi-threaded software. The Cinebench R23 multi-core score of 918 would result in single-digit frame rates in most 3D games, and the Geekbench single-core score of 295 is far below the threshold for responsive web browsing with heavy JavaScript. Instead, the i3-350M targets three specific scenarios:

• Legacy office productivity: Spreadsheets, word processing, and email clients from the early 2010s run acceptably, as these are largely single-threaded but low-demand. The single-core score of 295, while low, is sufficient for such tasks.
• Embedded or industrial control: Systems that run fixed, lightweight software (e.g., point-of-sale terminals, basic data logging) benefit from the 35 W TDP and constant clock speed, which simplifies thermal design.
• Retro computing enthusiasts: Users building a period-correct Windows 7 or XP machine will find the i3-350M's performance aligns with its contemporary rivals, as the 0.1-0.6% deltas against Athlon II and Pentium parts show.

For any workload involving video encoding, 3D rendering, or modern web applications, the data is unambiguous: the 3rd percentile ranking means nearly every other CPU in the database outperforms it. Users should look elsewhere.

FAQ

Q: How does the Intel Core i3-350M compare to the AMD Athlon II X2 255?

A: They are statistically identical. The i3-350M has an average benchmark score of 353, while the Athlon II X2 255 scores 353, yielding a delta of -0.1%. There is no measurable performance difference between them.

Q: What is the best-case performance scenario for this chip?

A: The strongest result is the Cinebench R23 multi-core score of 918, which represents the most demanding workload the chip can handle. Even so, this score places it at the 3rd percentile of all CPUs, indicating very low absolute performance.

Q: Does the i3-350M support overclocking?

A: No. The multiplier is locked, and the boost clock is null, meaning the chip operates at a fixed 2.27 GHz with no user-accessible frequency adjustments.

Q: What memory type does this processor use?

A: It supports DDR3 memory. ECC memory is not supported, and there is no memory bus or bandwidth data available in the benchmark records.

Q: Is the integrated graphics part of the CPU?

A: No. The integrated graphics are a chipset feature available on certain motherboards, not integrated into the CPU die itself. This means the chip's 35 W TDP excludes any GPU load.

Q: What is the production status of the Core i3-350M?

A: It is end-of-life. Production has ceased, and it was released on January 6, 2010, making it a legacy part with no modern availability outside the used market.

Platform and Compatibility

The i3-350M uses the Intel Socket G1, which is a mobile-specific socket. It is based on the Westmere architecture with the Arrandale codename, fitting into the Core i3 generation. The chip is manufactured on a 32 nm process at Intel's foundry, with a die size of 81 mm² and 382 million transistors. Memory support is limited to DDR3, with no ECC capability, and the PCIe interface is Gen 2. The integrated graphics are not on-die; they rely on a chipset feature, meaning the motherboard must include that functionality for video output.

The upgrade path is effectively nonexistent for modern users. Socket G1 is obsolete, and the end-of-life status means no new motherboards are produced. Users seeking a replacement would need to source used boards and chips, but the performance ceiling is so low that any upgrade within the same socket would yield marginal gains. The 3 MB shared L3 cache and 64 KB L1 per core, 256 KB L2 per core are fixed, and there is no total L3 or vCache 3D data to suggest expandability. For a system builder, this platform is a dead end; it is only relevant for repairing or preserving existing hardware.

Single-Thread vs Multi-Thread Behavior

The split between single-thread and multi-thread performance is stark. In Cinebench R23, the multi-core score of 918 is 7.1x higher than the single-core score of 129, which is a larger gap than the 2x physical core count would suggest. This indicates that the chip's two cores with Hyper-Threading (four threads total) scale efficiently in multi-threaded workloads, but the single-thread performance is extraordinarily weak. The Geekbench results show a similar pattern: 596 multi-core versus 295 single-core, a 2.02x scaling factor that matches the expected 2x from dual cores without Hyper-Threading overhead.

For real-world use, this means the i3-350M is disproportionately better at parallel tasks that can utilize all four threads, such as older video encoding tools or multi-threaded benchmarks. However, the absolute single-thread scores (54 in Cinebench R20, 129 in R23) are so low that even well-parallelized software will struggle because the base performance per thread is insufficient. In contrast, the nearest rivals — the Athlon II X2 255, Pentium E6700, and Athlon II X2 240e — all have average scores within 0.6% of the i3-350M, but those are dual-core parts without Hyper-Threading, so they would likely exhibit better single-thread behavior relative to their multi-thread scores. The data suggests that the i3-350M's multi-thread advantage is real but moot: a 918 R23 score is below what many modern laptops achieve in single-core alone. Users relying on single-threaded applications (e.g., older spreadsheet macros, legacy database front-ends) will find the 295 Geekbench single-core score the limiting factor, while those running batch operations on multiple files may see the full 4-thread benefit.
