AMD Ryzen AI 7 350 vs Intel Core i5-13450HX Comparison

The Intel Core i5-13450HX and the AMD Ryzen AI 7 350 are two mobile processors that land at nearly the same overall performance tier, with average benchmark scores of 34333 and 34222 respectively. The data shows a split decision across individual tests, with the Intel part winning 8 of the 15 head-to-head comparisons and the AMD part taking 7. The overall average scores place both CPUs within a 0.3% delta of each other, and both hold the 84th percentile among all CPUs, indicating that the choice between them comes down to workload-specific strengths rather than a clear overall winner.

Head-to-Head Benchmarks

The most decisive victory in the entire data set belongs to Intel in floating-point math. The Core i5-13450HX scores 61776 in PassMark floating point math, which is 16.1% ahead of the Ryzen AI 7 350's 53230. This is the largest single delta between the two chips and suggests a substantial advantage in workloads that rely heavily on floating-point calculations, such as scientific simulations or certain rendering tasks.

Intel also shows a solid lead in multi-threaded Cinebench tests. In Cinebench R23 multi-core, the i5-13450HX scores 16797 versus the Ryzen's 16014.5, a 4.9% advantage. The Cinebench R15 multi-core test shows a closer margin, with Intel ahead by a slim 1% (2503 vs 2477). The PassMark multi-thread test follows a similar pattern, with the Intel part scoring 25084 against 24935, a 0.6% edge. These results indicate that the 10-core Intel processor holds a consistent, if sometimes modest, advantage when all cores are engaged.

The Ryzen AI 7 350 fights back strongly in single-core performance. The most striking result is in Cinebench R15 single-core, where the AMD chip scores 294 versus Intel's 248, a 15.6% lead. This advantage narrows in Cinebench R23 single-core, where the Ryzen scores 1958 against 1746, a 10.8% margin. The PassMark single-thread test also favors AMD, with scores of 3834 vs 3553, a 7.3% difference. These results clearly demonstrate that the Zen 5 architecture delivers superior per-thread performance in this comparison.

Beyond the headline multi-core and single-core splits, there are several other notable differences. Intel wins data encryption by 9.1% (16632 vs 15244) and physics by 11.5% (1504 vs 1349). AMD counters with a 12% win in extended instructions (21678 vs 19083) and a 4% win in random string sorting (33266 vs 31940). The remaining tests are closer: Intel leads data compression by 0.6% (305990 vs 304089), find prime numbers by 3.8% (83 vs 80), and integer math goes to AMD by 2.9% (85651 vs 83209). The average benchmark scores of 34333 for Intel and 34222 for AMD reflect this near-total balance in overall capability.

Where Each One Wins

The Intel Core i5-13450HX is the stronger choice for compute-heavy parallel workloads. Its 16.1% lead in floating-point math is the single largest margin in the comparison, making it well-suited for applications that stress FPU throughput. The 4.9% advantage in Cinebench R23 multi-core and the 11.5% lead in physics also point to a processor that handles sustained multi-threaded rendering and simulation tasks with greater efficiency. The 9.1% edge in data encryption adds a security-focused workload to Intel's column, where the 20 MB of shared L3 cache likely helps maintain throughput during cryptographic operations.

The AMD Ryzen AI 7 350 is the clear winner in single-threaded responsiveness. The 15.6% lead in Cinebench R15 single-core and the 10.8% margin in Cinebench R23 single-core indicate that day-to-day tasks which depend on one or two cores will feel snappier on the AMD chip. The 7.3% advantage in PassMark single-thread performance reinforces this pattern. AMD also demonstrates strengths in specific instruction sets, with a 12% lead in extended instructions and a 4% win in random string sorting, suggesting better handling of specialized code paths and sorting algorithms. The 2.9% lead in integer math shows that AMD also holds a slight edge in general arithmetic operations.

For users who prioritize multi-core rendering or physics calculations, the Intel part's consistent wins in those categories make it the safer bet. For those who value single-core speed and instruction-level efficiency, the AMD part's dominant single-thread scores are hard to ignore. The two chips trade wins so evenly that the deciding factor will be the specific mix of applications a user runs most frequently.

Finally, the Intel part has a launch MSRP of $326, while no launch MSRP is listed for the AMD part.

Architecture Differences

The architectural split between these two chips is significant. The Intel Core i5-13450HX is built on the Raptor Lake architecture with the Raptor Lake-HX codename, using a 10 nm process node fabricated by Intel. It features a die size of 257 mm². In contrast, the AMD Ryzen AI 7 350 uses the Zen 5 architecture with the Krackan Point codename, built on a 4 nm process node from TSMC, with a die size of 195 mm². Cache hierarchies differ notably: both have 80 KB of L1 cache per core, but Intel has 2 MB of L2 cache per core versus AMD's 1 MB per core. The L3 cache is significantly different, with Intel offering 20 MB shared and AMD offering 8 MB. The Intel part belongs to the Core 13th Gen series and the Core i5 (Raptor Lake-HX) generation, while the AMD part is from the Ryzen AI 300 generation, which uses a combination of Zen 5 and Zen 5c cores. The Intel chip was released on 2023-01-03, while the AMD chip was released on 2025-01-05. Both are mobile segment parts and are currently active in production.

The Verdict

The data points to a clear split recommendation. For users who run heavily multi-threaded workloads such as 3D rendering, physics simulations, or data encryption, the Intel Core i5-13450HX is the better choice, as it wins 8 of the 15 head-to-head benchmarks including the largest margin in the set (16.1% in floating-point math) and a 4.9% lead in Cinebench R23 multi-core. Its 10-core configuration and 20 MB of L3 cache provide the foundation for these wins, and the higher 55 W TDP suggests it can sustain that performance under load.

For users who prioritize single-thread responsiveness, instruction-set flexibility, or power efficiency, the AMD Ryzen AI 7 350 is the stronger pick. Its 15.6% lead in Cinebench R15 single-core and 10.8% lead in Cinebench R23 single-core are decisive, and it also wins in extended instructions and integer math. The lower 28 W TDP and 4 nm process node indicate a more power-efficient design, which matters for thinner laptops where thermal headroom is limited. The AMD part's higher 5.00 GHz boost clock supports its single-core advantages. Given that the average benchmark scores are within 0.3% of each other and both sit at the 84th percentile, the decision rests on whether multi-core throughput or single-core speed matters more for the intended use case.
