Intel Core i7-2860QM

The Intel Core i7-2860QM is a mobile quad-core processor from the Sandy Bridge generation, released in September 2011. It runs at a base clock of 2.50 GHz and boosts to 3.60 GHz, with eight threads across four cores. The 45W TDP, 32nm process, and 1,160 million transistors on a 216 mm² die place it in the mainstream mobile segment. Its integrated Intel HD 3000 graphics, dual-channel memory bus, and 8 MB of shared L3 cache complete the package. In aggregate benchmark performance, it scores an average of 1127, placing it at the 32nd percentile of all CPUs.

Benchmark Performance

The i7-2860QM delivers consistent results across multiple benchmark suites. In Cinebench R15, it scores 393 multicore and 55 single-core. Cinebench R20 yields 1640 multicore and 231 single-core, while R23 reports 3907 multicore and 551 single-core. Geekbench shows 1681 multicore and 558 single-core. These numbers reflect a processor that sits firmly in the mid-range of its era, with the average benchmark score of 1127 anchoring it at the 32nd percentile.

Compared to its nearest rivals, the performance deltas are razor-thin. The i7-2860QM matches the Intel Core i3-4370 exactly, with a delta of 0% and an identical average score of 1127. It edges out the Intel Core i5-3330S by 0.1%, a margin that is statistically insignificant. Against the Intel Core i7-3612QM and the Intel Core i7-2720QM, it trails by 0.3% in both cases. These sub-percent differences mean that in real-world applications, the i7-2860QM is effectively on par with all four rivals, regardless of their architectural differences.

The multicore scores show strong scaling from the 4-core/8-thread configuration. The R23 multicore result of 3907 is more than seven times the single-core score of 551, indicating that the processor can fully utilize all threads when the workload allows. The R20 and R15 multicore scores of 1640 and 393 follow the same pattern, reinforcing the idea that parallel workloads are where this chip excels. The Geekbench multicore score of 1681 further corroborates this, while the single-core scores across all tests remain modest, ranging from 55 in R15 to 558 in Geekbench.

Power and Thermals

The i7-2860QM has a TDP of 45W, a figure that defines its thermal envelope and cooling requirements. This TDP is typical for a mobile quad-core processor of the Sandy Bridge generation, and it implies that a standard laptop cooling solution—a heatpipe and a small fan—is sufficient to maintain boost clocks under load. The 32nm process, combined with 1,160 million transistors on a 216 mm² die, suggests a moderate power density that is manageable within a notebook chassis. The integrated Intel HD 3000 graphics adds no additional TDP requirement beyond the package, as it is part of the same silicon.

The end-of-life production status means that no new thermal designs are being developed for this chip, but for existing systems, the 45W TDP allows for a compact and quiet cooling solution. The locked multiplier further simplifies thermal management, as there is no overclocking headroom to account for. For system integrators, the 45W figure is a key specification for battery life and chassis design, as it directly impacts the size and weight of the cooling assembly.

Single-Thread vs Multi-Thread Behavior

The benchmark results reveal a clear split between single-thread and multi-thread performance. The single-core scores—55 in Cinebench R15, 231 in R20, 551 in R23, and 558 in Geekbench—are modest by any standard. The boost clock of 3.60 GHz provides a moderate frequency advantage, but the Sandy Bridge architecture, despite its age, does not deliver exceptional per-core throughput. For lightly threaded applications such as web browsing, office productivity, or older games that rely on a single core, the i7-2860QM will feel adequate but not fast.

Multi-threaded workloads, on the other hand, benefit greatly from the eight threads. The R23 multicore score of 3907 is roughly seven times the single-core score, and the R20 and R15 multicore results follow a similar ratio. This indicates that the processor scales well with thread count, making it suitable for video encoding, 3D rendering, and software compilation. The Geekbench multicore score of 1681 further confirms that tasks which can spread across all cores will see a significant uplift. The ability to boost to 3.60 GHz on one core while maintaining multi-thread throughput is a practical advantage for mixed workloads that alternate between single and multi-threaded phases.

How It Compares

Intel Core i3-4370: The i7-2860QM matches the i3-4370 exactly in average benchmark score, with a delta of 0%. This is a notable parity, as the i3-4370 is a desktop part while the i7-2860QM is a mobile quad-core. The performance tie suggests that the extra cores and threads of the i7-2860QM do not provide an advantage in the aggregate benchmarks, likely because the i3-4370's higher single-thread performance compensates for its fewer cores.

Intel Core i5-3330S: The i7-2860QM is 0.1% faster than the i5-3330S. This margin is negligible and falls well within run-to-run variance. The two processors are effectively identical in overall performance, meaning that users would not notice a difference in everyday tasks or even in multi-threaded workloads. The delta of 0.1% is too small to influence any purchasing decision.

Intel Core i7-3612QM: The i7-2860QM trails the i7-3612QM by 0.3%. This is a small but consistent gap, likely reflecting a slight architectural refinement in the newer i7-3612QM. However, the difference is so minor that it would not be perceptible in real-world applications. For a user comparing these two mobile chips, the i7-2860QM offers essentially the same performance at a lower cost (though cost is not discussed here).

Intel Core i7-2720QM: The i7-2860QM also trails the i7-2720QM by 0.3%. The two processors are close relatives within the same generation, with the 2860QM being a minor refresh. The delta of 0.3% is consistent with the gap to the i7-3612QM, suggesting that all three i7 mobile parts are within a hair's breadth of each other. Upgrading from a 2720QM to a 2860QM would yield no measurable benefit.

Who Should Consider It

The i7-2860QM is best suited for users who run multi-threaded applications. The R23 multicore score of 3907 and Geekbench multicore of 1681 indicate strong parallel performance for a 2011 mobile processor. Content creation tasks such as video editing, 3D rendering, and software compilation will leverage the eight threads effectively, making this chip a reasonable choice for a laptop used as a portable workstation. For gaming, the single-core score of 551 in R23 is modest; older games that rely on a single core will run acceptably, but modern titles that demand high single-thread performance may be limited. The integrated HD 3000 graphics can handle basic display output, but a discrete GPU is recommended for any serious gaming.

Office productivity and general web browsing are well within the capabilities of this processor, as these workloads are not heavily multi-threaded and the boost clock of 3.60 GHz provides adequate responsiveness. The 45W TDP makes it suitable for laptops where battery life is a consideration, though the end-of-life status means it is only available in used or refurbished systems. Users who need a budget-friendly mobile CPU for multi-threaded tasks, without requiring top-tier single-core performance, will find the i7-2860QM a viable option.

Platform and Compatibility

The i7-2860QM uses the Intel Socket G2 (988B), a mobile socket found in laptops and portable workstations. It supports dual-channel memory, though the specific memory types are not listed in the available data. ECC memory is not supported, which is typical for a consumer mobile processor. The integrated Intel HD 3000 graphics provides video output without a discrete GPU, and the multiplier is locked, preventing overclocking. The 32nm Sandy Bridge architecture is a mature platform, and the processor is end-of-life, so no new motherboards or systems are being produced.

Upgrading from this processor would require a new motherboard and likely a new system, as the socket is not compatible with newer generations. For existing systems, the part number SR02X identifies this specific SKU. The lack of PCIe information in the available data means that expansion capabilities cannot be assessed from this analysis, but the dual-channel memory bus and integrated graphics cover the basic connectivity needs. The 45W TDP and mobile socket make this a drop-in replacement for compatible laptops, provided the BIOS supports the Sandy Bridge architecture.
