Intel Core i3-2310M

The Intel Core i3-2310M is a dual-core mobile processor from the Sandy Bridge architecture, released in early 2011 and now end-of-life. It operates at a base clock of 2.10 GHz with no boost capability, supports four threads via Hyper-Threading, and carries a 35 W TDP. The benchmark data places this chip at the 5th percentile of all CPUs, indicating it sits firmly in the entry-level segment for laptops of its era.

Benchmark Performance

The average benchmark score for the Intel Core i3-2310M is 393, which places it in a tightly contested cluster of rivals. In Cinebench R23, the processor scores 1036 points in multi-core and 146 points in single-core tests. The Cinebench R20 results show 435 points multi-core and 61 points single-core, while the older Cinebench R15 yields a multi-core score of 104. Geekbench results are lower in absolute terms, with a multi-core score of 645 and a single-core score of 322.

Comparing against its nearest rivals, the data reveals a remarkably narrow performance gap. The Intel Core i5-430M averages 392 points, which is just 0.2% behind the i3-2310M. The AMD A6-3400M scores 394 points, putting it 0.3% ahead. The Intel Core i3-380M trails at 390 points, a 0.7% deficit, while the Intel Core i3-2332M leads at 396 points, 0.7% ahead. These deltas are within the margin of measurement noise, suggesting that all four processors deliver statistically equivalent aggregate performance.

The percentile rank of 5 means that 95% of all recorded CPUs outperform this chip. This is not a surprising result for a dual-core mobile processor from 2011, but it contextualizes the scores: the i3-2310M is designed for basic productivity, not demanding workloads. The multi-core scores, particularly the Cinebench R23 result of 1036, indicate that the processor can handle light compilation or rendering tasks, but it will struggle with modern multi-threaded applications that expect four or more physical cores.

Single-Thread vs Multi-Thread Behavior

The split between single-thread and multi-thread performance reveals the architectural strengths and limitations of the i3-2310M. In Cinebench R23, the single-core score of 146 translates to a multi-core score of 1036, which is a scaling factor of roughly 7.1x. This is unusually high for a dual-core processor, suggesting that the single-thread performance is the bottleneck and that the two physical cores with Hyper-Threading are being utilized efficiently when all four threads are active.

In Geekbench, the single-core score of 322 against a multi-core score of 645 shows a scaling factor of exactly 2.0x, which is the theoretical maximum for two cores with perfect parallelization. This indicates that the Geekbench workload scales well across the available threads, but the absolute scores are low. The Cinebench R20 results show 61 single-core and 435 multi-core, a 7.1x scaling again, reinforcing that the single-thread performance is the limiting factor in this architecture.

For real-world workloads, this split means that the i3-2310M will feel responsive in single-threaded tasks like web browsing, document editing, or light spreadsheet work, where the 2.10 GHz base clock is sufficient. However, any application that relies heavily on single-thread performance, such as older games or certain legacy software, will see performance capped by the lack of turbo boost. The absence of a boost clock is notable; the processor cannot dynamically increase its frequency above 2.10 GHz, so all workloads run at the same clock speed.

Who Should Consider It

Given the benchmark scores, the Intel Core i3-2310M is suitable for basic office tasks and light web usage. The single-core Geekbench score of 322 and Cinebench R23 single-core score of 146 are adequate for word processing, email, and browsing with a few tabs open. Users who primarily run productivity suites like Microsoft Office or Google Workspace will find the performance acceptable, though modern web pages with heavy JavaScript may cause occasional lag.

For gaming, the i3-2310M is not a viable option for contemporary titles. The 5th percentile ranking and low multi-core scores (435 in Cinebench R20) indicate that even older games from the early 2010s will run at low settings and reduced resolutions. The integrated Intel HD 3000 graphics further limit gaming capability, as the processor must share system memory for graphics operations. Casual games from the same era as the processor, such as indie titles or 2D platformers, may be playable, but any 3D game will struggle.

Content creation is similarly constrained. The multi-core Cinebench R23 score of 1036 suggests that the processor can handle light photo editing in tools like Photoshop, but video rendering or 3D modeling will be slow. Users attempting to encode video or compile code will experience long wait times compared to even a mid-range processor from the same generation. The processor is best suited for users who need a basic laptop for email, browsing, and document creation, with no expectation of heavy multitasking.

How It Compares

Intel Core i5-430M: The i5-430M scores 392 points on average, which is 0.2% behind the i3-2310M. This is effectively a tie, but the i5-430M likely offers a boost clock that the i3-2310M lacks, meaning real-world single-thread performance could be higher on the i5 despite the similar aggregate score.

AMD A6-3400M: The A6-3400M averages 394 points, 0.3% ahead of the i3-2310M. This is a negligible margin, but the AMD processor includes a more capable integrated GPU, which could make it a better choice for light gaming despite the CPU performance being comparable.

Intel Core i3-380M: The i3-380M scores 390 points, 0.7% behind the i3-2310M. This is the largest deficit among the rivals, but still within noise. The i3-380M is from the same Sandy Bridge generation and likely has a similar architecture, so the performance difference is minimal.

Intel Core i3-2332M: The i3-2332M leads the group with 396 points, 0.7% ahead of the i3-2310M. This is the closest rival in terms of architecture, likely differing only in clock speed. The slight edge suggests the 2332M may have a higher base clock, but the difference is not significant for real-world use.

Platform and Compatibility

The Intel Core i3-2310M uses the Intel Socket G2 (988B) socket, which is specific to mobile platforms from the Sandy Bridge era. The processor is built on a 32 nm process node with 624 million transistors on a 149 mm² die. It supports DDR3 memory in a dual-channel configuration, with no ECC support, and integrates Intel HD 3000 graphics. The processor has a 35 W TDP, which is typical for a mobile dual-core chip of this generation.

The architecture is Sandy Bridge, and the processor is part of the Core i3 generation. It has 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 3 MB of shared L3 cache. The part number is SR04R, and the multiplier is locked, meaning no overclocking is possible. The production status is end-of-life, so the processor is no longer manufactured and would be found only in used or refurbished laptops.

For upgrade paths, the Socket G2 platform supports other Sandy Bridge processors, including higher-end Core i5 and i7 models. Users with a laptop using this socket could potentially upgrade to a faster processor, but this is rarely practical in mobile systems due to thermal and BIOS limitations. The memory support for DDR3 is standard for the era, and the dual-channel configuration helps maximize memory bandwidth for the integrated graphics.
