Intel Core i3-2330M

The Intel Core i3-2330M is a mobile dual-core processor from the Sandy Bridge generation, released on May 31, 2011. It runs at a fixed 2.20 GHz base clock with no boost clock specified, and it is built on Intel's 32 nm process. The chip integrates Intel HD 3000 graphics and is now end-of-life. With a 2-core, 4-thread configuration, it targets entry-level laptops from the early 2010s. The data below places it in the 5th percentile of all CPUs, indicating a very low performance tier relative to the broader processor landscape.

Platform and Compatibility

The Intel Core i3-2330M uses the Intel Socket G2 (988B), a mobile socket designed for thin and standard laptop chassis. This socket is exclusive to the Sandy Bridge generation of mobile processors, and the data lists no other compatible CPUs, suggesting a closed upgrade path. The chip is fabricated on a 32 nm process with 624 million transistors and a die size of 149 mm², reflecting the design constraints of its era.

Memory support is limited to DDR3 in a dual-channel configuration. The system does not support ECC memory, which is typical for consumer mobile platforms. The integrated graphics controller is Intel HD 3000, which shares system memory for its operations. No PCIe information is provided in the data, so the expansion capabilities remain unspecified. The processor's production status is end-of-life, meaning it is no longer manufactured or sold, and systems using this socket are largely obsolete.

How It Compares

Against the Intel Pentium G6951, the Core i3-2330M trails by 0.2% in average benchmark score. The Pentium G6951, despite being a desktop part, performs essentially identically to the mobile i3 in aggregate. This near parity is notable because the i3 has two additional threads, yet the Pentium's higher clock speed compensates.

The Intel Celeron G555 is 0.6% faster on average. Again, the difference is negligible, falling within run-to-run variance. The Celeron G555 is a dual-core desktop chip without Hyper-Threading, yet it edges out the i3-2330M in the composite score, highlighting the i3's modest single-thread efficiency.

The Intel Core i3-3227U, a newer Ivy Bridge ultrabook chip, is 0.7% ahead. The i3-3227U has a lower TDP and a similar dual-core/thread design, but its architectural improvements give it a slight edge. The delta is small enough that real-world differences would be imperceptible.

The Intel Core i3-390M, an older Arrandale dual-core, is 0.8% faster. This is the largest gap among the rivals, yet still under 1%. The i3-390M runs at a higher base clock (not specified here) and has a similar thread count, explaining its marginal advantage. Overall, the i3-2330M sits in a tight cluster of low-end processors from the same era, all within 1% of each other.

Power and Thermals

The TDP is rated at 35 watts, a typical figure for a dual-core mobile processor of its generation. This thermal envelope requires a cooling solution capable of dissipating 35W of heat, which in laptops is usually a small fan and heat pipe assembly. The absence of a boost clock means the processor runs at a constant 2.20 GHz under load, avoiding the power spikes associated with turbo modes. As a result, thermal management is relatively predictable, though the chip's age and 32 nm process mean it is less efficient than modern parts. The integrated graphics also contribute to the thermal load, but the overall power draw remains modest for a laptop CPU.

FAQ

Q: What socket does the Intel Core i3-2330M use?

Q: What is the process node?

A: The chip is fabricated on a 32 nm process by Intel.

Q: Is the multiplier unlocked?

A: No, the multiplier is locked, preventing overclocking.

Benchmark Performance

The benchmark results show a processor that is clearly at the low end of the performance spectrum. In Cinebench R15 multi-core, it scores 107 points, a figure that is typical for a dual-core Sandy Bridge mobile chip. The Cinebench R20 multi-core score is 446, while the single-core score is 63, indicating a strong multi-thread scaling but a very low per-core throughput. The Cinebench R23 multi-core score of 1064 and single-core score of 150 follow the same pattern, with the multi-core result being roughly seven times the single-core result (though that ratio is not directly stated, the numbers speak for themselves). Geekbench scores are 665 for multi-core and 329 for single-core, again showing a roughly 2:1 ratio, which aligns with the 2-core/4-thread design.

The average benchmark score across all tests is 403, and the processor sits in the 5th percentile of all CPUs in the database. This means that 95% of processors outperform it, placing it firmly in the entry-level or legacy category. The nearest rivals, as listed, all have average scores between 404 and 406, confirming that the i3-2330M is essentially at the bottom of its peer group. The deltas are all negative, ranging from -0.2% to -0.8%, so it is the slowest among the four comparable chips, though the differences are trivial.

Single-Thread vs Multi-Thread Behavior

The i3-2330M's single-thread performance is extremely weak by modern standards. In Cinebench R23, the single-core score is 150, which is less than half of what many contemporary low-end chips achieve. This is a direct consequence of the 2.20 GHz base clock and the Sandy Bridge architecture, which lacks the instruction-level improvements of later generations. The multi-thread score of 1064 is higher, but the improvement is only about seven times the single-thread score, which is typical for a dual-core with Hyper-Threading. In Geekbench, the multi-core score of 665 is roughly double the single-core score of 329, reflecting the expected scaling from two cores and four threads.

For real-world workloads, this means the processor can handle light multi-threaded tasks such as web browsing with multiple tabs or office productivity, but it will struggle with any modern application that demands high single-thread performance, such as video encoding or complex spreadsheets. The lack of a boost clock further limits responsiveness in bursty tasks. The multi-thread advantage is present but not enough to compensate for the low absolute performance. Overall, the chip's behavior is consistent with a dual-core design from 2011: acceptable for basic use, but far behind any current processor in both single- and multi-threaded scenarios.
