AMD Ryzen AI 7 345 vs Intel Core i5-14500HX Comparison

The Verdict

The recorded data presents a clear performance hierarchy between these two mobile processors. The Intel Core i5-14500HX dominates the AMD Ryzen AI 7 345 across nearly every benchmark in the comparison, winning 13 of the 15 head-to-head tests. The Intel part holds an average benchmark score of 35094, placing it in the 84th percentile of all CPUs, while the AMD chip averages 29461, landing in the 81st percentile.

The Intel Core i5-14500HX is the appropriate choice for workloads that depend on sustained multi-threaded throughput. Its 14 cores and 20 threads give it a structural advantage that shows in Cinebench R23 multicore, where it scores 24234 against the AMD's 11461, a 52.7% lead. That advantage repeats in PassMark multithread, with the Intel part scoring 28508 versus 19927, a 30.1% gap. For rendering, video encoding, or any task that scales across cores, the data consistently favors the Intel chip.

The AMD Ryzen AI 7 345 claims only two wins in the head-to-head set, both in PassMark single-thread tests. It scores 3875 in both PassMark single_thread and singlethread, beating the Intel's 3629 by 6.8%. This indicates the AMD design carries a modest single-thread efficiency advantage, but it does not translate into broader benchmark success. The Intel part wins Cinebench R23 single-core by a 46.9% margin, scoring 3421 against 1818, a result that contradicts the PassMark single-thread picture and suggests the AMD's single-thread win is workload-specific.

The AMD chip's lower 28 W TDP versus Intel's 55 W TDP suggests it targets thin-and-light systems where power draw matters more than peak performance. The Intel part, with its higher power envelope and larger physical design, suits larger laptops with more robust cooling. The data does not support a performance-per-watt calculation, but the specification gap in power allowance is substantial enough to define the intended use cases.

Buyers who prioritize the highest scores in the database should choose the Intel Core i5-14500HX. Buyers who need a processor that fits a 28 W thermal budget and still delivers competitive single-thread PassMark results should consider the AMD Ryzen AI 7 345.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 7 345 uses the Krackan Point codename and belongs to the Ryzen AI 300 generation, which combines Zen 5 and Zen 5c cores. It is manufactured on a 4 nm process at TSMC. The Intel Core i5-14500HX uses the Raptor Lake-HX architecture, belongs to the Core 14th Gen series as a Raptor Lake-HX Refresh, and is built on Intel's 10 nm process with a die size of 257 mm².

The cache hierarchies differ significantly. Both processors share an 80 KB L1 cache per core. The AMD part uses 1 MB of L2 per core, while the Intel part uses 2 MB per core. The L3 cache difference is substantial: the AMD chip has 4 MB total, while the Intel chip has 24 MB shared. This larger shared cache on the Intel side helps explain its strong performance in data-heavy workloads.

Memory support also diverges. The AMD Ryzen AI 7 345 supports DDR5 and LPDDR5X memory in a dual-channel configuration, with a recorded memory bandwidth of 89.6 GB/s. The Intel Core i5-14500HX supports DDR4 and DDR5, also dual-channel, but the database records no memory bandwidth figure for it. The Intel part supports ECC memory; the AMD part does not.

PCI Express capabilities differ as well. The AMD processor provides Gen 4 connectivity with 14 lanes from the CPU. The Intel processor provides Gen 5 connectivity with 16 lanes from the CPU. This gives the Intel part a newer and wider interface for discrete GPUs and storage.

The integrated graphics solutions are different. The AMD Ryzen AI 7 345 uses the Radeon 840M. The Intel Core i5-14500HX uses UHD Graphics 770. The database records no benchmark comparisons for either integrated GPU, so the analysis cannot rank their graphics performance.

The Intel part has an unlocked multiplier, while the AMD part does not. The Intel chip also carries a higher 55 W TDP, compared to the AMD's 28 W, which indicates the Intel design expects a larger thermal solution and a more generous power budget.

Specification Differences

The processors differ across nearly every major specification field. The AMD Ryzen AI 7 345 has 6 cores and 12 threads. The Intel Core i5-14500HX has 14 cores and 20 threads. Base clocks differ: the AMD runs at 2.00 GHz, the Intel at 2.60 GHz. Boost clocks differ: the AMD reaches 4.60 GHz, the Intel reaches 4.90 GHz.

The TDP figures show a 27 W gap. The AMD part draws 28 W, the Intel part draws 55 W. Socket types are incompatible: the AMD uses AMD Socket FP8, the Intel uses Intel BGA 1964.

L2 cache per core is 1 MB on the AMD and 2 MB on the Intel. L3 cache is 4 MB on the AMD and 24 MB shared on the Intel. The AMD supports DDR5 and LPDDR5X memory; the Intel supports DDR4 and DDR5. The AMD has a recorded memory bandwidth of 89.6 GB/s; the Intel has no recorded memory bandwidth. ECC support appears only on the Intel part.

PCIe generation and lane counts differ: the AMD has Gen 4 with 14 lanes, the Intel has Gen 5 with 16 lanes. Integrated graphics differ: Radeon 840M on the AMD, UHD Graphics 770 on the Intel. The Intel multiplier is unlocked; the AMD multiplier is locked.

Release dates differ by roughly one year. The Intel Core i5-14500HX was released on 2024-01-07. The AMD Ryzen AI 7 345 was released on 2025-01-14. Both parts are currently marked Active in production status. The Intel part number is SRMXJ; the AMD part number is 100-000002122.

The Intel chip has a recorded die size of 257 mm². The AMD chip has no recorded die size. Neither processor has a recorded transistor count, total L3 field, or 3D V-Cache.

Head-to-Head Benchmarks

The Intel Core i5-14500HX wins every Cinebench test in the comparison. In Cinebench R15 multicore, the Intel scores 2442 against the AMD's 1712, a 29.9% advantage. In Cinebench R15 single-core, the Intel scores 344 against 271, a 21.2% lead. The R23 results are even more lopsided. The Intel scores 24234 in R23 multicore, beating the AMD's 11461 by 52.7%. In R23 single-core, the Intel scores 3421 against 1818, a 46.9% margin. The single-core R23 gap is particularly striking because the AMD wins the PassMark single-thread tests, indicating the Intel's single-core advantage depends on the specific benchmark methodology.

The PassMark suite shows consistent Intel dominance across most tests. In data compression, the Intel scores 333851 against 237484, a 28.9% lead. Data encryption shows the Intel at 19502 versus 11814, a 39.4% advantage. Extended instructions favor the Intel by 15.1%, with scores of 20019 against 17003. The find prime numbers test shows the widest relative gap: the Intel scores 130, the AMD scores 62, a 52.3% difference. Floating point math favors the Intel at 69442 versus 42621, a 38.6% lead. Integer math shows the Intel at 95584 against 63475, a 33.6% advantage. Physics tests give the Intel a 43% lead, scoring 1911 versus 1089. Random string sorting favors the Intel by 29.8%, with scores of 36219 against 25435.

The PassMark multithread test confirms the pattern. The Intel scores 28508, the AMD scores 19927, a 30.1% gap. This result aligns with the core count difference: the Intel part has 14 cores and 20 threads, the AMD part has 6 cores and 12 threads.

The only AMD wins come in PassMark single_thread and PassMark singlethread. Both tests record identical scores: the AMD at 3875, the Intel at 3629. The 6.8% AMD advantage in these tests shows that the Zen 5 design in the AMD chip can outpace the Raptor Lake architecture in a narrow single-threaded workload. However, this success does not carry over to Cinebench R23 single-core, where the Intel leads by 46.9%, or to any other test in the head-to-head set.

The nearest rival data for both processors puts their average scores in context. The AMD Ryzen AI 7 345, with an average score of 29461, sits within 0.7% of the Intel Core i5-13500HX, which averages 29270. The Intel Core i5-14500HX, averaging 35094, falls within 0.3% of the Intel Core i9-12900HX, which averages 35003. This means the AMD part competes with the previous-generation Intel HX-class chip, while the current Intel part competes at the level of an older i9 HX flagship.

The overall benchmark picture is unambiguous. The Intel Core i5-14500HX delivers substantially higher multi-threaded and most single-threaded scores, backed by more cores, more cache, and a higher power envelope. The AMD Ryzen AI 7 345 offers a narrow single-thread PassMark win and a much lower TDP, making it a fit for power-constrained designs that do not require the Intel part's peak throughput.
