Intel Core i5-5675R vs Intel Core i7-5700HQ Comparison

The Intel Core i5-5675R and Intel Core i7-5700HQ are both 14 nm Broadwell parts sharing the same Intel BGA 1364 socket, yet benchmark results show they are not interchangeable. The data reveals a clear split: the i7-5700HQ dominates in Cinebench workloads while the i5-5675R takes a decisive lead in Geekbench tests. Their average benchmark scores are nearly identical—1648 for the i5 and 1645 for the i7—placing them within 0.2% of each other, but the distribution of wins tells a more complex story.

Head-to-Head Benchmarks

The most striking result is the Geekbench reversal. In Geekbench multicore, the Intel Core i5-5675R scores 3738 against 3129 for the Intel Core i7-5700HQ, a 19.5% advantage. The single-core Geekbench test shows a similar pattern: 1234 for the i5 versus 1085 for the i7, a 13.7% margin. These are substantial deltas, not marginal differences.

Cinebench paints the opposite picture. Across all three versions of the test, the i7-5700HQ wins by a consistent margin. In Cinebench R15 multicore, the i7 scores 519 against 476 for the i5, an 8.3% lead. The single-core R15 test shows 73 versus 67, an 8.2% gap. Cinebench R20 multicore delivers 2164 for the i7 versus 1987 for the i5, again 8.2% apart, while R20 single-core is 305 versus 280 (8.2%). Cinebench R23 multicore continues the trend: 5154 versus 4733 (8.2%), and R23 single-core 727 versus 668 (8.1%).

The i7-5700HQ wins six of the eight head-to-head benchmarks, while the i5-5675R takes two. Yet the average benchmark scores are nearly tied—1648 for the i5 and 1645 for the i7—because Geekbench pulls the i5’s average up and the i7’s down. The i7’s Cinebench wins are consistent but moderate in size, while the i5’s Geekbench wins are larger in percentage terms. This asymmetry suggests the two processors respond differently to the distinct workloads each benchmark suite presents.

Architecture Differences

Both processors are built on Intel’s 14 nm process node, with the same die size of 182 mm² and the same socket (Intel BGA 1364). They share dual-channel DDR3 memory support with identical memory bandwidth of 29.9 GB/s, and neither supports ECC memory. PCIe connectivity is also the same: Gen 3 with 16 lanes from the CPU.

The core counts differ. The i5-5675R has 4 cores and 4 threads, while the i7-5700HQ has 4 cores and 8 threads thanks to Hyper-Threading. This thread disparity is the most obvious architectural differentiator, yet it does not translate into a universal performance advantage for the i7, as the Geekbench results demonstrate.

Cache allocation diverges as well. The i5-5675R carries 4 MB of shared L3 cache, while the i7-5700HQ has 6 MB of shared L3 cache. Both have 64 KB of L1 cache per core and 256 KB of L2 cache per core. The extra 2 MB of L3 in the i7 likely contributes to its Cinebench strength, though the i5’s Geekbench advantage suggests other factors are at play.

Clock speeds favor the i5 in base and boost frequencies. The i5-5675R runs at 3.10 GHz base and 3.60 GHz boost, compared to 2.70 GHz base and 3.50 GHz boost for the i7-5700HQ. Thermal design power differs notably: the i5 is rated at 65 W, while the i7 is rated at 47 W. Despite the lower TDP, the i7 sustains competitive multi-threaded performance, indicating efficient power management.

Integrated graphics also differ. The i5-5675R uses Iris Pro Graphics 6200, while the i7-5700HQ uses Intel HD 5600. The i5’s graphics solution is positioned as a more capable integrated GPU, which aligns with its desktop market segment. The i7’s market segment is listed as desktop as well, though its part number and characteristics suggest a mobile-oriented design.

The production status separates the two as well. The i5-5675R is marked as active, while the i7-5700HQ is end-of-life. Release dates are close—the i5 launched on 2015-05-14 and the i7 on 2015-06-01—but their lifecycles have diverged.

Where Each One Wins

The i7-5700HQ is the clear winner for multi-threaded rendering workloads. Cinebench R15, R20, and R23 all show the i7 ahead by roughly 8% in both multicore and single-core variants. This consistency across three generations of the Cinebench test indicates a fundamental advantage in how the i7 executes rendering instructions. The extra threads and larger L3 cache likely underpin this performance. For users running CPU-based render tasks, the i7’s scores are the stronger data points.

The i5-5675R wins decisively in Geekbench tests. A 19.5% multicore lead and a 13.7% single-core lead are not small margins. Geekbench’s workload mix evidently favors the i5’s higher clock speeds and its particular cache hierarchy. The i5’s 3.10 GHz base clock and 3.60 GHz boost clock are both higher than the i7’s 2.70 GHz and 3.50 GHz, which may explain its Geekbench dominance. For general-purpose computing tasks that resemble Geekbench’s test suite, the i5 is the better performer.

The i7’s wins in Cinebench single-core tests are notable because they come despite lower clock speeds. The i7 scores 73 in R15 single-core versus 67 for the i5, and 727 in R23 single-core versus 668. This suggests the i7’s architecture extracts more per-clock performance in these specific workloads, or that its larger L3 cache provides a benefit even in single-threaded scenarios.

The i5’s lower TDP of 65 W versus the i7’s 47 W may seem counterintuitive given the i5’s higher clocks, but the i7’s efficiency in Cinebench indicates it delivers more performance per watt in rendering tasks. The i5’s advantage in Geekbench comes at a higher power cost, which matters in thermally constrained systems.

For users prioritizing rendering applications, the i7-5700HQ is the data-backed choice. For users prioritizing general system responsiveness and Geekbench-style workloads, the i5-5675R is superior. The nearly identical average scores—1648 versus 1645—mean the overall performance tier is the same, but the workload-specific outcomes are clearly differentiated.
