AMD Ryzen AI 7 450G vs Intel Core i5-14450HX Comparison

The AMD Ryzen AI 7 450G and Intel Core i5-14450HX represent two distinct approaches to high-performance x86 computing, with the AMD part targeting the desktop segment and the Intel chip designed for mobile platforms. The recorded data shows a decisive overall victory for the AMD processor in the shared Passmark benchmark suite, as it secures 9 wins out of 11 head-to-head tests. The Intel Core i5-14450HX does manage to take two specific tests, but the magnitude and breadth of the AMD lead in most workloads establishes a clear performance hierarchy between these two parts.

Head-to-Head Benchmarks

The most striking difference in the data appears in the Passmark data compression test, where the AMD Ryzen AI 7 450G scores 402831 against the Intel Core i5-14450HX's 278538. This translates to a 44.6% advantage for the AMD processor, representing the largest single-test margin in the comparison. The random string sorting test follows a similar pattern, with the AMD part scoring 42663 versus Intel's 29565, a 44.3% lead. These two results indicate a substantial advantage for AMD in memory-intensive and data-manipulation workloads.

The extended instructions test shows an even larger percentage gap. The AMD Ryzen AI 7 450G scores 28223, while the Intel Core i5-14450HX manages only 17207, giving AMD a 64% advantage. This is the largest relative margin in the entire head-to-head comparison and suggests that the AMD architecture handles SIMD-style workloads with significantly greater efficiency. The integer math test reinforces this picture, with AMD scoring 99732 against Intel's 78330, a 27.3% lead.

Multithreaded performance follows the same trajectory. The AMD Ryzen AI 7 450G scores 30422 in the Passmark multithread test, compared to the Intel Core i5-14450HX's 23680, a 28.5% advantage. This result is notable because the Intel processor actually has more physical cores: 10 cores and 16 threads versus the AMD part's 8 cores and 16 threads. Despite the core-count deficit, the AMD processor still delivers a decisive win in this throughput-oriented benchmark, which points to higher per-core efficiency on the Zen 5 / Zen 5c architecture.

Single-thread performance also favors AMD. The Ryzen AI 7 450G scores 4309 in the Passmark single-thread test, while the Intel Core i5-14450HX scores 3643, giving AMD an 18.3% advantage. This result aligns with the higher boost clock of the AMD part, which reaches 5.10 GHz compared to Intel's 4.80 GHz. The floating point math test shows a narrower margin, with AMD scoring 63683 versus 58037, a 9.7% lead.

Data encryption favors AMD by a 21.6% margin, with scores of 18937 against 15574. This workload often benefits from dedicated instruction extensions, and the AMD processor's advantage here is consistent with its strong showing in the extended instructions test.

The Intel Core i5-14450HX does secure two wins. In the find prime numbers test, Intel scores 98 against AMD's 87, an 11.2% margin. This is the largest Intel victory and suggests that the Intel architecture handles this particular integer-heavy, branch-dependent workload more effectively. The physics test also goes to Intel, with a score of 1475 versus AMD's 1440, a 2.4% margin. This is a much closer result, and it represents the smallest difference in the entire comparison.

The overall average benchmark score reinforces the AMD advantage. The Ryzen AI 7 450G posts an average score of 63331, placing it in the 93rd percentile of all CPUs in the database. The Intel Core i5-14450HX averages 32040, which places it in the 82nd percentile. The nearest rivals in the database confirm the positioning: the AMD part sits near the Intel Core Ultra 7 265HX with a 0.2% delta, while the Intel chip's closest competitor is the Intel Core i7-13705H with a -0.1% delta.

The Verdict

The data points to a clear overall winner. The AMD Ryzen AI 7 450G outperforms the Intel Core i5-14450HX in 9 of the 11 recorded benchmark tests, with margins ranging from 9.7% to 64%. The Intel part's two victories are narrow in the case of the physics test and isolated to a single specialized workload in the case of prime number calculation. For general-purpose computing, multithreaded throughput, and single-thread responsiveness, the AMD processor is the stronger part based on the recorded measurements.

The Intel Core i5-14450HX should be considered primarily by users who prioritize the two specific workloads where it holds an advantage: prime number finding and physics simulation. The 11.2% lead in the former and the 2.4% lead in the latter are real, but they cover a narrow slice of the benchmark suite. The AMD processor's 18.3% single-thread advantage and 28.5% multithread advantage are far more consequential for typical application performance.

The percentile data also separates the two parts. The AMD Ryzen AI 7 450G ranks in the 93rd percentile of all CPUs, while the Intel Core i5-14450HX ranks in the 82nd percentile. This 11-point gap in the distribution reflects the substantial difference in average benchmark scores: 63331 for AMD versus 32040 for Intel.

Where Each One Wins

The AMD Ryzen AI 7 450G claims the majority of the performance landscape. Its largest wins come in extended instructions, where the 64% lead over Intel indicates a major architectural advantage for vectorized and specialized instruction workloads. The 44.6% lead in data compression and the 44.3% lead in random string sorting point to a strong memory subsystem and efficient data movement. The 28.5% multithread advantage makes the AMD part the better choice for parallel workloads such as rendering, compilation, and scientific computing, even though it uses fewer physical cores.

The AMD processor also wins decisively in integer math, with a 27.3% margin, and in data encryption, with a 21.6% margin. Its 18.3% single-thread lead covers the broad category of latency-sensitive applications, including everyday desktop use and lightly threaded productivity software. The 9.7% floating point advantage further extends the AMD lead into numerically intensive applications.

The Intel Core i5-14450HX wins in exactly two tests. The 11.2% advantage in find prime numbers is the only double-digit margin for Intel, and it indicates a specific strength in a workload that the AMD architecture handles less efficiently. The physics test shows a 2.4% Intel lead, a narrow margin that suggests near-parity in this particular simulation workload. Outside of these two tests, the Intel processor trails by margins that range from 9.7% to 64%.
