AMD Ryzen AI 7 450G vs Intel Core i5-14500HX Comparison

Head-to-Head Benchmarks

The benchmark data shows a clear overall victory for the AMD Ryzen AI 7 450G, which wins 7 of the 11 recorded head-to-head comparisons. The most decisive margin comes in extended instructions, where the AMD part scores 28,223 versus 20,019 for the Intel Core i5-14500HX, a 41% advantage. This category reflects performance on specialized instruction sets, and the gap is substantial enough to indicate a major architectural edge for the AMD processor in workloads that leverage those extensions.

Data compression also favors the AMD chip heavily. The Ryzen AI 7 450G records 402,831 points against 333,851 for the Intel part, a 20.7% lead. This is one of the largest single-test deltas in the entire comparison and suggests the AMD processor handles compression workloads with significantly greater efficiency. Single-thread performance tells a similar story: the AMD part scores 4,309 in both the passmark_single_thread and passmark_singlethread tests, while the Intel chip manages 3,629, giving AMD an 18.7% edge. That is a meaningful difference for any application that relies heavily on single-core responsiveness.

The AMD processor also wins in multithread performance, scoring 30,422 versus 28,508 for Intel, a 6.7% advantage. Given that the Intel chip has 14 cores and 20 threads compared to 8 cores and 16 threads for AMD, this result is particularly notable. The AMD part compensates for its lower core count with higher per-core efficiency. Integer math goes to AMD as well, with 99,732 points against 95,584, a 4.3% margin. Random string sorting also favors AMD: 42,663 versus 36,219, a 17.8% difference.

The Intel Core i5-14500HX claims four wins. The largest is in find prime numbers, where Intel scores 130 against 87 for AMD, a 33.1% advantage. This is a striking reversal given AMD's dominance elsewhere, and it indicates that the Intel architecture handles this particular mathematical workload much more effectively. Physics simulation also goes to Intel: 1,911 versus 1,440, a 24.6% lead. This suggests the Intel chip has an edge in workloads that stress physical simulation calculations.

Floating point math favors Intel by 8.3%, with scores of 69,442 versus 63,683. Data encryption is the closest contest of all: Intel wins with 19,502 against 18,937, a razor-thin 2.9% margin. While the AMD processor wins more tests overall, the Intel chip's victories are concentrated in specific compute-heavy areas, and its physics and prime number results are decisive.

Where Each One Wins

The AMD Ryzen AI 7 450G is the stronger choice for workloads that involve data compression, integer math, string sorting, and extended instruction sets. The 20.7% compression lead and the 41% extended instructions margin are the standout results. For single-threaded applications, the 18.7% advantage makes AMD the clear pick. Multithreaded tasks also favor AMD despite the core count disadvantage, with a 6.7% win.

The Intel Core i5-14500HX is better suited for physics simulation, prime number calculations, and floating point math. The 24.6% physics lead and 33.1% prime number advantage are substantial. For encryption workloads, Intel holds a narrow edge, but the 2.9% margin is small enough that real-world differences would be difficult to notice.

Looking at the broader benchmark landscape, the AMD processor sits in the 93rd percentile of all CPUs in the database, while the Intel chip ranks in the 84th percentile. The average benchmark score for AMD is 63,331, nearly double the Intel average of 35,094. This overall scoring gap reflects the fact that the AMD part dominates in the passmark test suite, while the Intel chip's strongest results come from Cinebench and Geekbench tests that are not part of the head-to-head comparison.

Architecture Differences

The two processors come from fundamentally different design approaches. The AMD Ryzen AI 7 450G uses the Gorgon Point codename and belongs to the Ryzen AI 400 generation built on the Zen 5 and Zen 5c architecture. It is manufactured on a 4 nm process at TSMC with a die size of 195 mm². The Intel Core i5-14500HX uses the Raptor Lake-HX codename, belongs to the Core 14th Gen series, and is built on the Raptor Lake architecture with a Raptor Lake-HX Refresh designation. Intel uses a 10 nm process at its own foundry, with a larger die size of 257 mm².

Core configurations differ significantly. The AMD chip has 8 cores and 16 threads, while the Intel part has 14 cores and 20 threads. Despite having fewer cores, the AMD processor achieves higher multithread scores, indicating superior per-core throughput. Cache layouts also diverge. Both chips have 80 KB of L1 cache per core. The AMD processor has 1 MB of L2 per core and 8 MB of L3 cache. The Intel chip has 2 MB of L2 per core and 24 MB of shared L3 cache. The larger L3 cache on the Intel side does not translate into a benchmark advantage in the recorded tests.

Memory support differs as well. The AMD processor supports DDR5 and LPDDR5X memory with dual-channel configuration and a memory bandwidth of 89.6 GB/s. The Intel chip supports both DDR4 and DDR5 in dual-channel mode, but the database does not record a memory bandwidth figure for it. Both processors support ECC memory. PCIe connectivity favors Intel: the Core i5-14500HX offers Gen 5 with 16 lanes from the CPU, while the AMD part provides Gen 4 with 12 lanes from the CPU.

Integrated graphics also differ. The AMD processor includes the Radeon 860M, while the Intel chip uses UHD Graphics 770. The AMD part has an unlocked multiplier, as does the Intel chip. The AMD processor uses the AMD Socket AM5 and is classified as a desktop part, while the Intel chip uses Intel BGA 1964 and is classified as mobile. The AMD chip has a base clock of 2.00 GHz and a boost clock of 5.10 GHz, with a TDP of 65 watts. The Intel chip has a base clock of 2.60 GHz and a boost clock of 4.90 GHz, with a TDP of 55 watts.

The Verdict

The benchmark data favors the AMD Ryzen AI 7 450G in the majority of recorded comparisons. It wins 7 of 11 head-to-head tests, including the largest margin of the entire set with a 41% lead in extended instructions. Its single-thread advantage of 18.7% and compression lead of 20.7% make it the stronger choice for general-purpose computing, single-threaded applications, and data-heavy workloads. The 93rd percentile ranking versus 84th for Intel reinforces this conclusion.

The Intel Core i5-14500HX remains competitive in specific niches. Its 33.1% win in prime number calculations and 24.6% win in physics simulation indicate clear strengths in those areas. The floating point math advantage of 8.3% and the narrow encryption win of 2.9% add to its case. Users whose workloads emphasize physics simulation, prime number computation, or floating point math may prefer the Intel chip.

For everything else, the AMD Ryzen AI 7 450G delivers better recorded performance. The multithread win despite fewer cores shows architectural efficiency that the Intel chip cannot match in most tests. The AMD processor also offers a higher boost clock and a newer process node, which likely contributes to its benchmark dominance.
