Intel Core i5-5675C vs Intel Core i7-4910MQ Comparison

Head-to-Head Benchmarks

The benchmark results paint a sharply split picture. In every Cinebench test, the Intel Core i7-4910MQ comes out ahead, while in every Geekbench test, the Intel Core i5-5675C dominates. The margins are consistent within each suite, which suggests the two CPUs are optimized for different types of workloads.

Starting with Cinebench R15, the i7-4910MQ scores 536 in the multi-core test against the i5-5675C's 495, a 7.6% advantage. The single-core gap is similar: 75 versus 69, an 8% edge. Moving to Cinebench R20, the pattern holds. The i7-4910MQ records 2236 multi-core and 315 single-core, while the i5-5675C manages 2063 and 291, respectively. The deltas are 7.7% and 7.6%. Cinebench R23 repeats the story: the i7-4910MQ scores 5326 multi-core and 752 single-core, beating the i5-5675C's 4912 and 693 by 7.8% in both tests.

Then comes Geekbench, where the results invert dramatically. The i5-5675C scores 4159 in multi-core, which is 23.5% higher than the i7-4910MQ's 3368. The single-core result is even more lopsided: 1388 versus 1116, a 24.4% gap. This is not a marginal difference; it is a substantial lead that flips the overall comparison.

The data implies that the i7-4910MQ excels in sustained rendering-style workloads, likely because of its higher thread count. The i5-5675C, despite having only four threads, outperforms in Geekbench, which may reflect different memory access patterns or architectural efficiencies. The wins tally is 6 for the i7-4910MQ and 2 for the i5-5675C, but the magnitudes of the Geekbench victories are much larger than any single Cinebench loss.

Architecture Differences

The two processors come from different Intel generations and manufacturing processes. The i5-5675C uses the Broadwell architecture built on a 14 nm process node, while the i7-4910MQ uses the Haswell architecture on a 22 nm node. This is a significant generational gap, and the smaller process node gives the i5-5675C an efficiency advantage, though the i7-4910MQ compensates with a higher thread count.

The i7-4910MQ has 4 cores and 8 threads, enabled by Hyper-Threading, while the i5-5675C has 4 cores and 4 threads. This doubling of threads is the most likely explanation for the i7-4910MQ's consistent wins in Cinebench, which scales well with additional threads. The i5-5675C, lacking Hyper-Threading, must rely on its architectural efficiency and higher base clock to compete.

Cache configurations also differ. The i5-5675C has 4 MB of shared L3 cache, while the i7-4910MQ has 8 MB of shared L3 cache. Both have 64 KB L1 and 256 KB L2 per core. The larger L3 cache on the i7-4910MQ likely helps in data-heavy workloads, but the i5-5675C's Broadwell architecture may use its cache more efficiently.

The integrated graphics differ as well. The i5-5675C features Iris Pro Graphics 6200, while the i7-4910MQ uses Intel HD 4600. This is notable because Iris Pro is generally considered a more capable integrated GPU solution. The i5-5675C also has an unlocked multiplier, allowing overclocking, whereas the i7-4910MQ is locked.

Production status separates the two further. The i5-5675C is listed as Active, while the i7-4910MQ is End-of-life. The i5-5675C was released on 2015-05-14, and the i7-4910MQ on 2014-01-19, making the i7-4910MQ the older part by over a year.

The i5-5675C has a higher base clock by 0.20 GHz, but the i7-4910MQ has a higher boost clock by 0.30 GHz. The i7-4910MQ also has a lower TDP at 47 W versus 65 W, which is unusual for a mobile part but makes sense given its intended use in laptops. The i5-5675C is a desktop chip with a larger die at 182 mm², while the i7-4910MQ's die is 177 mm².

Both support DDR3 memory in dual-channel configuration with 25.6 GB/s bandwidth, and neither supports ECC. Both use PCIe Gen 3 with 16 lanes from the CPU. The memory support and PCIe lanes are identical, which means the performance differences come down to architecture, threads, and clocks.

Where Each One Wins

The i7-4910MQ is the clear winner in Cinebench workloads across all versions. R15, R20, and R23 all show the same pattern: the i7-4910MQ leads by roughly 7.6% to 8% in both multi-core and single-core tests. This suggests that for rendering, 3D modeling, or any application that uses Cinebench-like rendering algorithms, the i7-4910MQ is the more capable processor. Its 8 threads give it a structural advantage in multi-threaded tasks, and the higher boost clock of 3.90 GHz helps in single-threaded rendering as well.

The i5-5675C wins decisively in Geekbench, with 23.5% and 24.4% leads in multi-core and single-core respectively. Geekbench tests a broader range of real-world scenarios, including encryption, compression, image processing, and machine learning tasks. The i5-5675C's Broadwell architecture appears to handle these varied workloads more efficiently. The 14 nm process node likely contributes to lower latency and better instruction-level parallelism.

For users running Cinebench-style applications, the i7-4910MQ is the safer choice. For users whose workloads resemble Geekbench's mixed suite, the i5-5675C offers a substantial advantage. The i5-5675C also has the benefit of an unlocked multiplier, which allows overclocking to push its clocks beyond the stock 3.60 GHz boost. The i7-4910MQ, being locked and end-of-life, offers no such headroom.

In terms of integrated graphics, the i5-5675C's Iris Pro Graphics 6200 is a stronger solution for light gaming or media tasks without a discrete GPU. The i7-4910MQ's HD 4600 is a more basic implementation. This makes the i5-5675C a better fit for compact desktop builds where a dedicated graphics card is not present.

The Verdict

The choice between these two CPUs depends entirely on the target workload. The data is unambiguous: the i7-4910MQ wins every Cinebench test, and the i5-5675C wins every Geekbench test. There is no overlap in the results, which makes the decision straightforward for a user who knows their primary applications.

If the workload is rendering, video encoding, or any task that relies on Cinebench-style multi-threaded performance, the i7-4910MQ is the better processor. Its 8 threads and 8 MB L3 cache provide a measurable edge, and its 3.90 GHz boost clock keeps single-threaded rendering competitive. The i7-4910MQ also draws less power at 47 W, which could be an advantage in thermally constrained environments.

If the workload is general-purpose computing, mixed productivity, or anything that Geekbench measures, the i5-5675C is the superior part. The 23.5% multi-core lead and 24.4% single-core lead are not small margins. The i5-5675C also benefits from being an Active product on a desktop socket, which means it is still available and supported. Its unlocked multiplier adds flexibility for enthusiasts who want to extract more performance.

The average benchmark scores are close, with the i5-5675C at 1759 and the i7-4910MQ at 1716, but this masks the divergent strengths. The i7-4910MQ is the rendering champion, while the i5-5675C is the general-purpose winner. Users should match the CPU to their specific application mix. The data does not support a single universal recommendation, but it does provide a clear rule: Cinebench-heavy workloads favor the i7-4910MQ, and Geekbench-heavy workloads favor the i5-5675C.
