Intel Core i3-2312M

The Intel Core i3-2312M is a mobile processor from Intel’s Sandy Bridge architecture, manufactured on a 32 nm process with 624 million transistors and a 149 mm² die. It has two cores and four threads at a base clock of 2.10, with no boost clock listed. Cache is made up of 64 KB of L1 and 256 KB of L2 per core, plus a shared 3 MB L3, and the integrated graphics are Intel HD 3000. Its aggregate benchmark score is 347, placing it at the 3rd percentile among all CPUs in the database.

Benchmark Performance

The aggregate benchmark score of 347 puts the i3-2312M at the low end of the CPU field. Its closest rival, the Core i3-2367M, has an average score of 348 and a delta of -0.1%, meaning the i3-2312M trails by 0.1%. The Pentium E5800, Celeron 3755U, and Pentium E6600 each have an average score of 345 and a delta of 0.5%, meaning the i3-2312M leads each of them by 0.5%. These are tight margins, so the i3-2312M is essentially tied with its nearest rivals in aggregate throughput.

Individual Cinebench results reinforce that position. In Cinebench R23, the multi-core score is 1010 and the single-core score is 142. The multi-core figure is substantially higher than the single-core figure, showing that the two-core, four-thread design can use additional threads when a workload scales. In Cinebench R20, the multi-core score is 424 and the single-core score is 59. In Cinebench R15, the multi-core score is 101. All of these scores are low in absolute terms, and the single-core numbers in particular indicate limited per-thread compute capability.

The 3rd percentile ranking is the clearest summary. The i3-2312M sits in the lower reaches of the database, near several other low-scoring parts. Its aggregate score of 347 is consistent across the Cinebench results: none of the benchmark runs place it outside a narrow performance band. The nearest rivals have aggregate scores of 348 or 345, confirming that the i3-2312M is not meaningfully faster or slower than its immediate competition.

Power and Thermals

The TDP is documented as 35 W. That figure is the only thermal parameter in the dataset, and it defines the cooling tier: a 35 W-class mobile processor requires a conventional laptop cooling solution that can dissipate 35 W of heat under sustained load. The absence of a boost clock means there is no additional higher-frequency mode in the data that would create a larger transient thermal load.

The physical characteristics behind the 35 W TDP are the 32 nm process, 624 million transistors, and 149 mm² die. These are Sandy Bridge-generation figures, and the mobile market segment explains why the processor is designed around a relatively modest thermal envelope. At 35 W, the i3-2312M is not an ultra-low-power part, but it is also not a high-power desktop-class chip. The benchmark scores, combined with the 35 W TDP, suggest a processor whose power draw is in line with its low measured performance.

Who Should Consider It

The i3-2312M is best suited to workloads that do not require high per-thread speed. The single-core Cinebench R23 score is 142, and the single-core R20 score is 59; these numbers indicate that single-thread-focused applications will run at a modest level. Multi-core scores of 1010 in R23, 424 in R20, and 101 in R15 are sufficient for light parallel work, but the 3rd percentile ranking shows that heavy creation workloads are not a realistic target.

For office-style productivity, the two cores and four threads at a 2.10 base clock can handle basic document and browsing-type tasks, though the low single-core scores will cap responsiveness in demanding applications. For creation work, the Cinebench scores are the relevant evidence: rendering and encoding are possible, but the absolute scores are low, so completion times will be long. For gaming, the only graphics option is the integrated Intel HD 3000; no game benchmarks are recorded in the dataset, and the CPU’s low overall standing means demanding 3D titles are outside its intended envelope.

How It Compares

Against the Core i3-2367M, the i3-2312M is nearly identical. The rival’s average score is 348, and the delta of -0.1% indicates a negligible deficit for the i3-2312M. In aggregate benchmark terms, the two parts are interchangeable.

Against the Pentium E5800, the i3-2312M leads by 0.5%. The Pentium E5800 has an average score of 345, while the i3-2312M has 347. That half-percent advantage is too small to affect real-world performance.

Against the Celeron 3755U, the i3-2312M again leads by 0.5%. The Celeron’s average score is 345, placing it in the same cluster as the other rivals.

Against the Pentium E6600, the result is the same: a 0.5% advantage for the i3-2312M. The Pentium E6600 averages 345, so the i3-2312M’s 347 gives it a narrow but uniform edge over all three 345-scoring rivals.

Platform and Compatibility

The i3-2312M uses Intel Socket G2 (988B), a mobile socket matching the processor’s mobile market segment. The architecture is Sandy Bridge, and the generation is listed as Core i3 (Sandy Bridge). Memory support is DDR3 over a dual-channel interface, and ECC memory is not supported. The cache layout is 64 KB of L1 and 256 KB of L2 per core, with 3 MB of shared L3.

The process node is 32 nm, produced by Intel, with a transistor count of 624 million and a die size of 149 mm². The processor is end-of-life, with a release date of 2011-02-28. The multiplier is locked, so the 2.10 base clock is not adjustable through the CPU ratio. No PCIe information is present in the dataset, so expansion connectivity is unspecified. The part number is SR04PSR09S. Because the production status is end-of-life, the upgrade path is limited to legacy Socket G2 (988B) platforms; no newer socket compatibility is listed.
