Intel Core i5-5575R vs Intel Core i5-7440HQ Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive pattern across nearly every test category. The Intel Core i5-7440HQ wins 7 out of 8 head-to-head comparisons, with the only exception coming in Geekbench multi-core performance. In the Cinebench suite, the 7440HQ consistently leads by a narrow but uniform margin. In Cinebench R15 multi-core, it scores 463 against the 5575R's 435, a 6.4% advantage. The single-core R15 result follows the same shape: 65 versus 61, a 6.6% edge. Moving to R20, the 7440HQ posts 1933 in multi-core versus 1816, again a 6.4% delta, while single-core shows 272 against 256, a 6.3% difference. The R23 results mirror the pattern: 4603 versus 4324 in multi-core (6.5%) and 649 versus 610 in single-core (6.4%).

The consistency of these deltas is notable. Across all six Cinebench tests, the 7440HQ leads by between 6.3% and 6.6%. This suggests a uniform performance advantage that scales across both single-threaded and multi-threaded workloads. The Cinebench scores are all in the same ballpark, so the margin is not a result of one outlier test; it is a steady, repeatable gap.

The single exception is Geekbench multi-core, where the 5575R scores 3247 against the 7440HQ's 3043, a 6.3% reversal in favor of the older Broadwell part. This is an interesting divergence from the Cinebench results. Geekbench multi-core tends to emphasize memory latency and certain integer workloads, and the 5575R's dedicated memory bandwidth figure of 29.9 GB/s may play a role here. However, in Geekbench single-core, the 7440HQ reasserts its lead: 1184 versus 1072, a 10.4% advantage, the largest margin recorded in any test.

Overall, the 7440HQ holds the stronger average benchmark score at 1527, compared to 1478 for the 5575R, a difference of roughly 3.3%. Both processors sit at the 38th percentile among all CPUs in the database, meaning they occupy a similar performance tier overall. The nearest rivals for the 7440HQ include the Intel Core i5-4670S (avg score 1526, delta 0%), the Intel Pentium Gold G7400E (1524, delta 0.2%), and the Intel Xeon E5-1428L v2 (1537, delta -0.7%). The 5575R's nearest neighbors are the Intel Core i5-7500T (1483, delta -0.4%), the Intel Core i7-4710HQ (1473, delta 0.4%), and the Intel Xeon E3-1225 v5 (1465, delta 0.9%). These rival lists confirm that both chips are positioned in the same performance neighborhood, but the 7440HQ sits at the higher end of that neighborhood.

The Verdict

From the recorded data, the Intel Core i5-7440HQ is the faster processor in the majority of workloads. It wins every Cinebench test, both single and multi-core, and it wins Geekbench single-core by a double-digit margin. The 5575R only takes Geekbench multi-core, and that single victory does not offset the 7440HQ's broader consistency. For anyone running Cinebench-style rendering tasks, the 7440HQ is clearly the better choice. The data shows a 6.4% to 6.6% advantage across all three Cinebench versions, which is a meaningful and repeatable gap.

The 5575R's Geekbench multi-core win is worth acknowledging, but it appears to be workload-specific. If the target application is more aligned with Geekbench's multi-threaded integer and floating-point mix, the 5575R might offer a slight edge. However, the 7440HQ counters with a 10.4% lead in Geekbench single-core, which is a larger margin than the 5575R's multi-core advantage. The average benchmark scores reinforce this: 1527 versus 1478, a 49-point gap in favor of the 7440HQ.

The production status also matters for long-term planning. The 7440HQ is listed as end-of-life, while the 5575R is still active. This does not affect current performance, but it could influence availability and support considerations. The 7440HQ also has a lower TDP at 45 watts versus 65 watts, which is relevant for thermal-constrained systems. The verdict from the data is straightforward: the 7440HQ is the superior performer in most tests, and the 5575R only wins in one specific benchmark category.

Architecture Differences

The two processors come from different Intel microarchitectures. The 7440HQ is built on Kaby Lake, specifically the Kaby Lake-H variant, while the 5575R is a Broadwell design. Both use a 14 nm process node from Intel, so the manufacturing technology is the same generation. The die sizes differ significantly: the 7440HQ has a die size of 126 mm², while the 5575R is substantially larger at 182 mm². This size difference likely reflects the integrated graphics and other on-die components, not just the CPU cores.

Cache configurations also diverge. Both chips share the same L1 cache layout at 64 KB per core and the same L2 at 256 KB per core. The L3 cache, however, is different: the 7440HQ has 6 MB shared, while the 5575R has 4 MB shared. That is a 2 MB difference in favor of the 7440HQ, which could contribute to its consistent lead in cache-sensitive workloads.

The integrated graphics differ as well. The 7440HQ carries Intel HD Graphics 630, while the 5575R has Iris Pro Graphics 6200. The Iris Pro part is generally a more capable iGPU, but the database does not include graphics benchmarks, so any graphical advantage cannot be quantified from these records. The memory support also differs: the 7440HQ supports both DDR3 and DDR4, while the 5575R is limited to DDR3. The 5575R does list a memory bandwidth figure of 29.9 GB/s, but the 7440HQ does not have a corresponding value in the data.

The sockets are different: Intel BGA 1440 for the 7440HQ and Intel BGA 1364 for the 5575R. These are not interchangeable, so a motherboard designed for one cannot accept the other. The market segment also differs: the 7440HQ is a mobile part, while the 5575R is a desktop part. Despite the desktop classification, the 5575R has a higher TDP of 65 watts, while the mobile 7440HQ draws 45 watts. The release dates are separated by nearly two years, with the 5575R launching in May 2015 and the 7440HQ in January 2017.

Specification Differences

The two processors share several core specifications. Both have 4 cores and 4 threads, meaning neither supports hyper-threading. Both have a base clock of 2.80 GHz, and both have the same L1 and L2 cache structure. Neither supports ECC memory, and both use PCIe Gen 3 with 16 lanes from the CPU. Neither has an unlocked multiplier.

The differences are in the boost clock, TDP, socket, cache size, memory support, integrated graphics, and release timing. The 7440HQ boosts to 3.80 GHz, which is 0.50 GHz higher than the 5575R's 3.30 GHz. This boost advantage likely explains the 7440HQ's single-core wins. The TDP difference is 45 watts versus 65 watts, favoring the mobile part. The L3 cache is 6 MB versus 4 MB. Memory support is DDR3 and DDR4 versus DDR3 only. The 7440HQ uses HD Graphics 630, while the 5575R uses Iris Pro Graphics 6200. The launch MSRP for the 7440HQ was $250, and for the 5575R it was $265.

The part numbers differ: SR32R for the 7440HQ and SR2AK for the 5575R. The production status is end-of-life for the 7440HQ and active for the 5575R. The 5575R lists a memory bandwidth of 29.9 GB/s, while the 7440HQ has no such figure recorded. These are the only meaningful specification differences between the two.

Where Each One Wins

The Intel Core i5-7440HQ wins in every Cinebench test, covering R15, R20, and R23, in both single and multi-core variants. It also wins Geekbench single-core by a substantial margin. If the workload involves rendering, video encoding, or any single-threaded application, the 7440HQ is the clear choice. Its higher boost clock and larger L3 cache support these results. The 7440HQ also has a lower TDP, making it more suitable for thermally constrained mobile systems.

The Intel Core i5-5575R wins only in Geekbench multi-core. This single result suggests that in certain multi-threaded integer workloads, the 5575R can outperform the 7440HQ. The 5575R's dedicated memory bandwidth figure of 29.9 GB/s may explain this advantage in memory-intensive scenarios. For a desktop system where the workload aligns with Geekbench's multi-core patterns, the 5575R could be the better pick despite its lower average score.

The broader pattern is that the 7440HQ is faster in 7 of 8 tests, with margins between 6.3% and 10.4%. The 5575R's lone win is a 6.3% margin, which is smaller than the 7440HQ's single-core Geekbench advantage. The data favors the 7440HQ for general-purpose use, but the 5575R remains competitive in a narrow slice of multi-threaded performance.
