Where Each One Wins

The Intel Core i5-14500HX is the dominant performer across nearly every workload category in the database. It takes the win in Cinebench R20 multi-core with 10,178 versus 8,728, a 16.6% advantage, and extends that lead in Cinebench R23 multi-core to 44.3%. In single-core Cinebench R23, the 14500HX posts 3,421 against 1,746, a 95.9% margin, which is the largest single-test gap in the entire comparison. The 14500HX also leads in PassMark multi-threaded performance with 28,508 versus 25,084, a 13.7% edge, and in PassMark single-thread with 3,629 versus 3,553, a 2.1% margin.

The 13450HX’s only win is narrow and specific: Cinebench R15 multi-core. There, it scores 2,503, which is 2.4% higher than the 14500HX’s 2,442. This suggests that in older, shorter-duration multi-threaded workloads, the 13450HX can briefly edge ahead, possibly due to different power or boost behavior during the test. However, this advantage does not carry over to any other multi-core test, including Cinebench R20 or R23, where the 14500HX wins decisively.

For users prioritizing the latest rendering workloads, content creation, or any task that scales across many threads, the 14500HX is the clear choice. For legacy or synthetic multi-core scenarios similar to Cinebench R15, the 13450HX holds a small, isolated edge. In all other measured categories, including integer math, floating-point math, encryption, compression, and physics, the 14500HX takes the lead with margins ranging from 4.9% to 56.6%.

Architecture Differences

Both processors belong to Intel’s Raptor Lake family and share the same Raptor Lake-HX codename, but they are separated by one generation of release. The 14500HX is part of the Core 14th Gen lineup, described in the database as a Raptor Lake-HX Refresh, while the 13450HX is a Core 13th Gen part with the standard Raptor Lake-HX designation. Both use the same 10 nm process node from Intel and the same 257 mm² die size, indicating that the physical silicon foundation is identical.

The architectural difference manifests in core count and cache allocation. The 14500HX has 14 cores and 20 threads, giving it four additional threads over the 13450HX. Its L3 cache is 24 MB shared, compared to 20 MB shared on the 13450HX. Per-core L1 and L2 caches are identical at 80 KB and 2 MB respectively, so the larger total cache on the 14500HX comes purely from the additional cores. The 14500HX also has a higher boost clock at 4.90 GHz versus 4.60 GHz, and a higher base clock at 2.60 GHz versus 2.40 GHz.

The integrated graphics differ, with the 14500HX using UHD Graphics 770 and the 13450HX using UHD Graphics 710. Both chips support DDR4 and DDR5 memory over a dual-channel bus, and both support ECC memory. The PCIe configuration varies: the 14500HX provides Gen 5 with 16 lanes from the CPU, while the 13450HX provides Gen 5 with 20 lanes. This means the 13450HX can allocate more PCIe lanes to peripherals, while the 14500HX focuses on higher core performance per lane.

Specification Differences

The two processors differ on several key specification fields. The 14500HX has 14 cores and 20 threads, while the 13450HX has 10 cores and 16 threads. Base clock is 2.60 GHz for the 14500HX and 2.40 GHz for the 13450HX. Boost clock is 4.90 GHz for the 14500HX and 4.60 GHz for the 13450HX. Both have a TDP of 55 W and use the Intel BGA 1964 socket.

Cache configuration differs only at the L3 level: 24 MB shared on the 14500HX versus 20 MB shared on the 13450HX. The integrated GPU is UHD Graphics 770 on the 14500HX and UHD Graphics 710 on the 13450HX. The 14500HX supports PCIe Gen 5 with 16 lanes, while the 13450HX supports PCIe Gen 5 with 20 lanes. Both support DDR4 and DDR5 memory with a dual-channel bus and ECC capability.

The release dates differ: the 14500HX was released on 2024-01-07, while the 13450HX was released on 2023-01-03. The 13450HX has a launch MSRP of $326, while the 14500HX has no recorded launch MSRP in the database. Both processors have an unlocked multiplier and are currently listed as Active in production status. The part numbers are SRMXJ for the 14500HX and SRME8SRMEE for the 13450HX.

Head-to-Head Benchmarks

The benchmark data shows a clear pattern: the 14500HX wins 16 of 17 tests, with the 13450HX taking a single victory. The largest margin for the 14500HX comes in Cinebench R23 single-core, where it scores 3,421 against 1,746, a 95.9% advantage. This is an enormous gap for a single-core test and indicates a significant difference in per-thread performance, likely driven by the higher boost clock and newer refresh architecture.

In Cinebench R23 multi-core, the 14500HX scores 24,234 versus 16,797, a 44.3% lead. This is the second-largest margin in the comparison and reflects the combined benefit of more cores, higher clocks, and larger L3 cache. The multi-core advantage is consistent across other Cinebench versions: R20 shows a 16.6% lead (10,178 versus 8,728), and R15 shows a 2.4% deficit for the 14500HX (2,442 versus 2,503), which is the only instance where the 13450HX wins.

PassMark results reinforce the 14500HX’s dominance. In integer math, the 14500HX scores 95,584 versus 83,209, a 14.9% lead. Floating-point math shows a 12.4% edge (69,442 versus 61,776). Prime number finding has the largest PassMark gap at 56.6% (130 versus 83). Data encryption is 17.3% ahead (19,502 versus 16,632), and data compression is 9.1% ahead (333,851 versus 305,990). Extended instructions show a smaller 4.9% lead (20,019 versus 19,083).

The multi-threaded PassMark score is 28,508 for the 14500HX versus 25,084 for the 13450HX, a 13.7% margin. Single-thread PassMark is close: 3,629 versus 3,553, only a 2.1% difference. Physics simulation shows a 27.1% lead (1,911 versus 1,504), and random string sorting is 13.4% ahead (36,219 versus 31,940). Across all tests, the 14500HX’s average benchmark score is 35,094, placing it in the 84th percentile of all CPUs, with its nearest rival being the Intel Core i9-12900HX at 35,003 (0.3% delta). The 13450HX also sits in the 84th percentile with an average score of 34,333, and its nearest rival is the AMD Ryzen 7 3700X at 34,260 (0.2% delta).
