Intel Core i5-13420H vs Intel Core i7-1365U Comparison

Head-to-Head Benchmarks

The benchmark record for these two Raptor Lake mobile processors paints a clear picture of performance separation. The Intel Core i5-13420H wins 12 of the 17 head-to-head comparisons, while the Intel Core i7-1365U takes 5. This is not a close contest in aggregate, but the margins tell a nuanced story.

The Core i5-13420H dominates in multi-threaded workloads. In Cinebench R23 multi-core, it scores 11084 against the Core i7-1365U's 8946, a 23.9% advantage. The same pattern holds in Cinebench R20 multi-core, where the i5 leads 6013 to 4882, a 23.2% gap. Cinebench R15 multi-core shows a narrower 18.5% lead, with scores of 1738 versus 1466.5. This is a consistent multi-threaded advantage across all three Cinebench versions.

The PassMark suite reinforces this trend. The i5-13420H scores 17475 in PassMark multi-thread, 24.4% ahead of the i7-1365U's 14045. Data compression shows the largest absolute gap: 209450 versus 149585, a 40% difference. Extended instruction performance is even more lopsided, with the i5 at 12897 versus 8321, a 55% margin. Floating point math goes 42806 to 33689, a 27.1% gap. Integer math is closer but still favors the i5, 58156 to 50881, a 14.3% lead. Random string sorting shows a 29.9% advantage for the i5, 22045 to 16977. Data encryption also goes to the i5, 11559 to 9531, a 21.3% edge. Even physics simulation, the closest multi-threaded result, favors the i5 by 4.8%, 1012 to 966.

The Core i7-1365U, however, claims the single-threaded crown in most tests. Cinebench R23 single-core shows the i7 at 1887 versus 1689 for the i5, a 10.5% advantage. Cinebench R15 single-core follows with 265.5 versus 238, a 10.4% lead. The i7 also wins PassMark find prime numbers, 58 to 52, a 10.3% margin. PassMark single-thread is nearly identical, with the i7 at 3411 versus 3396, just 0.4% ahead.

The one outlier is Cinebench R20 single-core, where the i5-13420H wins 848 to 689, a surprising 23.1% margin. This result contradicts the other single-threaded tests, suggesting the i5's boost behavior is inconsistent across workloads. The data shows a processor that can spike high in one rendering test but lag in others, indicating that single-threaded performance is not uniformly stronger for either chip.

The Verdict

The data is unambiguous for multi-threaded workloads. The Intel Core i5-13420H is the superior choice for rendering, compilation, data processing, and any task that scales across cores. Its 23.9% lead in Cinebench R23 multi-core and 40% lead in data compression are decisive. The 55% margin in extended instructions is particularly notable, suggesting strong SIMD and AVX performance.

The Intel Core i7-1365U is the pick for single-threaded responsiveness. Its 10.5% advantage in Cinebench R23 single-core and 10.4% lead in Cinebench R15 single-core show a chip that handles lightly threaded tasks with more agility. The near-tie in PassMark single-thread, 3411 versus 3396, narrows this distinction, but the i7 still holds the edge.

For a desktop replacement laptop or a mobile workstation, the i5-13420H is clearly the better option. Its 45W TDP indicates a processor designed for sustained performance, and the benchmark results confirm that sustained load brings large wins. For a thin-and-light ultrabook where battery life and quiet operation matter more than raw throughput, the i7-1365U's 15W TDP and single-threaded wins make it the sensible choice. Both chips sit at the 72nd percentile among all CPUs, so neither is a low-end part, but they target different physical envelopes and use cases.

Architecture Differences

Both processors are built on Intel's Raptor Lake architecture and use the same 10 nm process node from Intel's own foundry. They share the same BGA 1744 socket, making them physically interchangeable in compatible laptops, though the power delivery requirements differ substantially.

The core configurations are the most significant architectural divergence. The i5-13420H has 8 cores and 12 threads, while the i7-1365U has 10 cores and 12 threads. The i7 has more physical cores but the same thread count, indicating that the i5 uses fewer cores with more aggressive multi-threading capabilities per core. This explains why the i5 wins multi-threaded tests despite having fewer cores: its higher power envelope allows each core to run faster under load.

Cache hierarchies differ as well. The i5-13420H has 80 KB of L1 cache per core and 2 MB of L2 cache per core, with 12 MB of shared L3 cache. The i7-1365U also has 80 KB of L1 per core but only 1.25 MB of L2 per core, with the same 12 MB of shared L3. The i5's larger L2 cache per core likely contributes to its multi-threaded dominance, as more data can be held closer to the execution units.

Clock speeds tell a complementary story. The i5-13420H has a base clock of 2.10 GHz and a boost clock of 4.60 GHz. The i7-1365U has a base clock of 1800.00 MHz (1.80 GHz) and a boost clock of 5.20 GHz. The i7's higher boost clock explains its single-threaded wins, while the i5's higher base clock and 45W TDP versus 15W TDP explain its sustained multi-threaded performance. The i7 can briefly sprint to 5.20 GHz, but the i5 can maintain higher clocks across all cores for longer periods.

The integrated graphics also differ. The i5-13420H uses Iris Xe Graphics with 80 execution units, while the i7-1365U uses Iris Xe Graphics with 96 execution units. The i7 has more GPU hardware, which could benefit lightly threaded graphical tasks, though the i5's higher CPU power budget might allow for better sustained GPU performance in shared thermal envelopes.

PCIe support differs as well. The i5-13420H offers Gen 5 with 8 lanes from the CPU, while the i7-1365U offers Gen 4 with the same 8 lanes. This makes the i5 better suited for fast storage or discrete GPUs that can use the newer PCIe standard. Both support DDR4 and DDR5 memory in dual-channel configuration, and neither supports ECC memory. Both are unlocked for no multiplier adjustment, meaning overclocking is not an option with either chip.
