Intel Core i5-3330 vs Intel Core i7-3632QM Comparison

The Intel Core i7-3632QM and the Intel Core i5-3330 are both Ivy Bridge processors, but they are built for entirely different platforms. The i7-3632QM is a mobile chip designed for laptops, while the i5-3330 is a desktop part. Despite the i5-3330 having a higher base clock of 3.00 GHz compared to 2.20 GHz, the benchmark data shows a consistent victory for the mobile i7 across every recorded test. The database shows the i7-3632QM winning all five head-to-head comparisons, with margins ranging from 15.5% to 15.7%. This outcome is driven primarily by the i7-3632QM’s support for 8 threads versus the i5-3330’s 4 threads, as well as its lower 35 W TDP, which allows it to deliver competitive performance in a more power-constrained environment.

Head-to-Head Benchmarks

The most striking result in the head-to-head data is the consistency of the i7-3632QM’s advantage. In Cinebench R15 multi-core, the i7-3632QM scores 406 against the i5-3330’s 351, a 15.7% lead. This pattern repeats almost exactly in Cinebench R20 multi-core, where the i7-3632QM scores 1693 compared to 1464, another 15.6% advantage. The single-core results tell a similar story. In Cinebench R20 single-core, the i7-3632QM scores 238 versus 206 for the i5-3330, a 15.5% margin. In Cinebench R23 single-core, the i7-3632QM scores 569, and the i5-3330 scores 492, which is a 15.7% difference. The largest absolute gap appears in Cinebench R23 multi-core, where the i7-3632QM reaches 4033 and the i5-3330 stops at 3486, a difference of 547 points.

What is notable is that the i7-3632QM achieves these wins despite its lower base clock. The i5-3330 runs at 3.00 GHz base and boosts to 3.20 GHz, while the i7-3632QM has a 2.20 GHz base clock and also boosts to 3.20 GHz. When both processors are at their maximum boost frequency, the i7-3632QM’s hyper-threading becomes the decisive factor. The i7-3632QM has 8 threads, exactly double the i5-3330’s 4 threads. In multi-threaded workloads, this thread advantage translates directly into the 15.6% to 15.7% gains seen across Cinebench R15, R20, and R23 multi-core tests. The fact that the single-core tests also favor the i7-3632QM by nearly the same percentage is more surprising, since neither chip has a clock advantage at boost. The data suggests that the i7-3632QM’s higher-end mobile design yields better per-clock execution in these specific Cinebench workloads.

The average benchmark scores in the database reinforce this hierarchy. The i7-3632QM has an average benchmark score of 1219, while the i5-3330 averages 1200. This is a modest overall difference of 19 points, but it is notably the i7-3632QM’s nearest rivals include the Intel Core i5-2500 at 1220 (a 0.1% gap) and the Intel Pentium Silver N6005 at 1218. The i5-3330’s nearest rivals are the AMD Athlon PRO 200GE at 1200 and the AMD Ryzen 3 2200G at 1202. Both CPUs sit in the 34th percentile of all CPUs in the database, meaning they are statistically equivalent in overall standing despite the i7-3632QM’s clear head-to-head wins.

Where Each One Wins

The i7-3632QM wins every benchmark in the comparison set. That makes the use-case split straightforward for multi-threaded work. In Cinebench R15 multi-core, the i7-3632QM is 15.7% ahead. In Cinebench R20 multi-core, it is 15.6% ahead. In Cinebench R23 multi-core, it is 15.7% ahead. These tests are heavily threaded, and the i7-3632QM’s 8 threads provide a clear advantage over the i5-3330’s 4 threads. For rendering, video encoding, or any workload that scales with thread count, the i7-3632QM is the stronger part based on the recorded data.

The single-core results also favor the i7-3632QM, though by a slightly narrower margin in R20 (15.5%) compared to the multi-core tests. In Cinebench R23 single-core, the margin is 15.7%. For everyday responsiveness or lightly threaded applications, the i5-3330’s higher base clock of 3.00 GHz does not translate into a win in any test. The i7-3632QM’s single-core scores are consistently higher, which indicates that its architecture and boost behavior deliver better results even when only one core is active.

There is no benchmark category in the database where the i5-3330 comes out ahead. The i5-3330 does have a desktop platform advantage, with support for PCIe Gen 3 with 16 lanes (CPU only) and DDR3 memory, but these platform features do not appear in the recorded performance tests. The i5-3330 also has a lower die size of 133 mm² compared to the i7-3632QM’s 160 mm², which suggests a simpler design, but that does not translate into benchmark wins. For users who already own an LGA 1155 motherboard, the i5-3330 is a functional quad-core desktop processor, but in direct comparison, it loses every recorded test.

Architecture Differences

Both processors are built on Intel’s Ivy Bridge architecture and use a 22 nm process node manufactured by Intel. They share the same core design philosophy, with 4 physical cores each. The L1 cache is identical at 64 KB per core, and the L2 cache is also the same at 256 KB per core. Both have 6 MB of shared L3 cache. The memory bus is dual-channel for both, and neither supports ECC memory.

The critical architectural difference is thread support. The i7-3632QM has 8 threads thanks to hyper-threading, while the i5-3330 has only 4 threads. This doubles the i7-3632QM’s logical core count and is the primary reason for its consistent multi-core wins. The i7-3632QM also has a lower TDP of 35 W, which is typical for a mobile processor, while the i5-3330 has a 77 W TDP, reflecting its desktop orientation. Despite the i5-3330’s higher power envelope, the i7-3632QM outperforms it in every benchmark.

The sockets are completely different. The i7-3632QM uses Intel Socket G2 (988B), which is a mobile socket, while the i5-3330 uses Intel Socket 1155, a desktop socket. This means the two chips are not interchangeable in any system. The integrated graphics also differ: the i7-3632QM has Intel HD 4000, while the i5-3330 has Intel HD 2500. The i7-3632QM’s transistor count is listed at 1,480 million, and its die size is 160 mm². The i5-3330’s transistor count is not recorded in the database, but its die size is 133 mm². The i5-3330 also has a recorded part number of SR0RQ and explicitly supports DDR3 memory, while the i7-3632QM’s memory support is not specified in the data. The i5-3330 supports PCIe Gen 3 with 16 lanes (CPU only), while PCIe support is not listed for the i7-3632QM.

The release dates are close, with the i5-3330 released on 2012-09-02 and the i7-3632QM released on 2012-10-18. Neither processor has a recorded launch MSRP in the database. Both have locked multipliers, so neither is designed for overclocking.

The Verdict

The data is unambiguous. The Intel Core i7-3632QM is the faster processor in every benchmark recorded in the database. It wins all five head-to-head comparisons, with margins between 15.5% and 15.7%. The i7-3632QM is the better choice for anyone who needs maximum multi-threaded performance, as demonstrated by its 4033 score in Cinebench R23 multi-core versus the i5-3330’s 3486. It also wins in single-core tests, making it the superior part across the board.

The i5-3330 is not a poor processor in absolute terms. Its average benchmark score of 1200 places it in the 34th percentile of all CPUs, the same percentile as the i7-3632QM. It is a functional quad-core desktop chip with a 3.00 GHz base clock and 3.20 GHz boost, and it supports DDR3 memory and PCIe Gen 3 with 16 lanes. For a desktop system that already uses Socket 1155, it remains a viable option. However, in a direct performance comparison, the i5-3330 does not win a single test.

The choice between these two processors comes down to platform rather than performance. The i7-3632QM is a mobile chip with a 35 W TDP, designed for laptops. The i5-3330 is a desktop chip with a 77 W TDP, designed for Socket 1155 motherboards. A user building or upgrading a desktop system would select the i5-3330 for its platform compatibility, not for its benchmark results. A user with a mobile Socket G2 system would benefit from the i7-3632QM’s superior performance and lower power draw. Based purely on the recorded benchmark data, the i7-3632QM is the clear winner.
