Intel Core i5-13450HX vs Intel Core i7-13700HX Comparison

The Intel Core i7-13700HX and Intel Core i5-13450HX are both Raptor Lake-HX mobile processors, but the benchmark data reveals a clear performance hierarchy between them. The i7 wins every single head-to-head comparison in the database, yet the average benchmark scores place them surprisingly close together, which raises questions about where the real-world differences matter most. The data shows a consistent pattern: the i7-13700HX is decisively faster in multi-threaded workloads, while the gap narrows considerably in single-threaded tasks.

Head-to-Head Benchmarks

The most striking result is the absolute sweep: the i7-13700HX wins all 17 head-to-head benchmark comparisons, with the i5-13450HX failing to claim a single victory. The largest margin appears in PassMark's find prime numbers test, where the i7 scores 124 against the i5's 83, a 49.4% advantage. This suggests a substantial difference in raw integer processing capability. Floating-point math also shows a major gap, with the i7 scoring 85,863 versus 61,776, a 39% lead, while integer math sits at 116,617 versus 83,209, a 40.1% difference. These are not marginal improvements; they indicate a fundamentally higher ceiling for compute-heavy tasks.

Multi-core rendering tests reinforce this trend. In Cinebench R15 multicore, the i7 scores 3,277 against the i5's 2,503, a 30.9% delta. Cinebench R20 multicore shows 11,290 versus 8,728, a 29.4% gap, and Cinebench R23 multicore follows with 20,479 versus 16,797, a 21.9% lead. The pattern holds in synthetic workloads: PassMark multithread shows 32,637 versus 25,084, a 30.1% advantage, and data compression tests show 392,725 versus 305,990, a 28.3% delta. Data encryption is another strong point, with 22,386 versus 16,632, representing a 34.6% gap.

The single-threaded picture is different in scale but still favors the i7. Cinebench R15 singlecore shows 272 versus 248, a 9.7% lead, while R20 singlecore shows 1,593 versus 1,232, a 29.3% delta that is surprisingly large for a single-core test. R23 singlecore narrows to 7.4% with 1,875 versus 1,746. PassMark single thread scores 3,819 versus 3,553, a 7.5% gap. The pattern suggests that the i7's higher boost clock contributes to single-core wins, but the multi-core advantage is the dominant story. The average benchmark scores tell a different narrative: the i7's avgBenchmarkScore is 34,554, while the i5 sits at 34,333, a delta of just 0.6%. This near-parity in averages, despite the sweeping head-to-head wins, likely reflects the weighting of different test types in the average calculation. The data implies that the i7 excels in sustained, heavily threaded workloads, while the i5 remains competitive in mixed or lightly threaded scenarios.

Architecture Differences

Both processors share the same fundamental architecture, Raptor Lake, built on Intel's 10 nm process node with a die size of 257 mm². The core counts diverge significantly. The i7-13700HX packs 16 cores and 24 threads, while the i5-13450HX offers 10 cores and 16 threads. This six-core and eight-thread deficit explains the multi-core benchmark results. The i7's base clock of 2.10 GHz is lower than the i5's 2.40 GHz, but the i7's boost clock of 5.00 GHz exceeds the i5's 4.60 GHz. This 0.40 GHz boost advantage helps the i7 in single-threaded tests, though the single-core deltas are smaller than multi-core ones.

Cache allocation also differs. Both use 80 KB of L1 per core and 2 MB of L2 per core, but the i7 has 30 MB of shared L3 cache versus the i5's 20 MB. That extra 10 MB of L3 likely benefits the i7 in data-heavy workloads, particularly in the encryption and compression tests where the i7 showed 34.6% and 28.3% leads respectively. The integrated graphics differ as well: the i7 features UHD Graphics 770, while the i5 ships with UHD Graphics 710. Both support DDR4 and DDR5 memory over a dual-channel bus, and both support ECC memory. The PCIe implementation is identical: Gen 5 with 20 lanes from the CPU. Both use the Intel BGA 1964 socket and carry the same 55 W TDP.

The part numbers differ, with the i7 listed as SRME5 and the i5 as SRME8SRMEE. Both are unlocked multipliers, both are marked as Active production status, and both were released on the same date of 2023-01-03. The i7's launch MSRP is $485, while the i5's is $326. The core count and cache differences are the primary architectural drivers, with the i7 offering 60% more cores and 50% more L3 cache.

Specification Differences

The key specification differences between the two processors are clear. The core count differs: 16 cores on the i7 versus 10 on the i5. Thread counts follow with 24 versus 16. The base clock is lower on the i7 at 2.10 GHz versus 2.40 GHz on the i5, but the boost clock is higher on the i7 at 5.00 GHz versus 4.60 GHz. L3 cache is 30 MB shared on the i7 and 20 MB shared on the i5. The integrated graphics differ, with UHD Graphics 770 on the i7 and UHD Graphics 710 on the i5. The part numbers are distinct: SRME5 for the i7 and SRME8SRMEE for the i5. The launch MSRP differs at $485 for the i7 and $326 for the i5.

Identical specifications include the socket (Intel BGA 1964), architecture (Raptor Lake), codename (Raptor Lake-HX), process node (10 nm), foundry (Intel), die size (257 mm²), L1 cache (80 KB per core), L2 cache (2 MB per core), memory support (DDR4, DDR5), memory bus (Dual-channel), ECC memory support (true), PCIe (Gen 5, 20 Lanes CPU only), market segment (Mobile), production status (Active), release date (2023-01-03), multiplier unlocked (true), and TDP (55 W). The i5's base clock advantage of 0.30 GHz does not translate to benchmark wins, suggesting that the i7's higher boost clock and core count are more decisive factors.

Where Each One Wins

The i7-13700HX is the clear winner in every benchmark category recorded. It dominates in multi-threaded workloads, with Cinebench R15 multicore showing a 30.9% lead, R20 a 29.4% lead, and R23 a 21.9% lead. PassMark multithread shows a 30.1% advantage, and the math tests show even larger gaps: 49.4% in prime number finding, 40.1% in integer math, and 39% in floating-point math. Data-intensive tasks also favor the i7, with data encryption showing a 34.6% lead and data compression a 28.3% lead. Extended instruction tests show a 26.4% advantage, and random string sorting shows a 30.6% lead. Physics tests show a 26.9% gap. The i7 wins all 17 head-to-head comparisons.

The i5-13450HX does not win any benchmark category outright. However, its closest performance is in single-threaded tests, where the deltas shrink to 7.4% in Cinebench R23 singlecore and 7.5% in PassMark single thread. The i5's lower avgBenchmarkScore of 34,333 versus the i7's 34,554 places it within 0.6% in aggregate terms. This means that for workloads that are not heavily threaded, the i5 may offer comparable responsiveness, especially given its higher base clock of 2.40 GHz. The i5's use case is likely in scenarios where single-threaded performance is more important than multi-threaded throughput, though the data shows the i7 still wins those tests. The i5 is not a winner in any recorded test, but it is a closer contender in lightly threaded scenarios.

The Verdict

The data is unambiguous: the Intel Core i7-13700HX is the superior processor in every recorded benchmark. It wins all 17 head-to-head comparisons, with advantages ranging from 7.4% in single-threaded tests to 49.4% in prime number finding. The i7's 16 cores and 24 threads versus the i5's 10 cores and 16 threads drive the multi-core wins, while the 5.00 GHz boost clock versus 4.60 GHz supports the single-core victories. The 30 MB L3 cache versus 20 MB adds further separation in data-heavy workloads. The i7 also carries a higher launch MSRP of $485 versus $326, reflecting its higher core count and cache allocation.

The i5-13450HX, despite losing every head-to-head benchmark, remains a capable processor in its own right. Its 84th percentile ranking matches the i7, and its avgBenchmarkScore of 34,333 is only 0.6% behind the i7's 34,554. For users whose workloads are not primarily multi-threaded, the i5's higher base clock of 2.40 GHz could offer snappy single-threaded responsiveness, though the i7 still wins those tests by 7.4% to 9.7%. The i5 also shares the same platform features, including DDR4/DDR5 support, ECC memory, and Gen 5 PCIe, making it a valid choice for systems where the extra cores of the i7 are not essential. The verdict from the data is clear: the i7-13700HX is for users who need maximum multi-threaded performance in a mobile platform, while the i5-13450HX is for those who prioritize the lower launch MSRP and are willing to accept the multi-core deficit. The i7's 30.1% lead in PassMark multithread and 30.9% lead in Cinebench R15 multicore make it the pick for rendering, compilation, and simulation workloads. The i5 holds its ground in aggregate averages, but the i7 is the definitive winner in every measured category.
