AMD Ryzen 5 150 vs Intel Core i5-13450HX Comparison

The Intel Core i5-13450HX and AMD Ryzen 5 150 are both mobile processors, but the benchmark data reveals a stark performance disparity. The Intel part, a Raptor Lake-HX chip with 10 cores and 16 threads, dominates the AMD Ryzen 5 150, a Zen 3+ part with 6 cores and 12 threads, across every single measured workload. The data shows a decisive victory for Intel, with the Ryzen 5 150 failing to win a single head-to-head comparison.

Head-to-Head Benchmarks

The most dramatic gap appears in the passmark_physics test, where the Intel Core i5-13450HX scores 1504 against the AMD Ryzen 5 150's 806. That is an 86.6% advantage, the largest delta of any benchmark in the comparison. This result suggests the Intel chip's architecture is far more efficient at handling the physics simulation workloads, which often rely on complex instruction sequences and high memory bandwidth.

Floating-point math is another area of complete Intel dominance. The i5-13450HX achieves a score of 61776 in passmark_floating_point_math, while the Ryzen 5 150 manages only 35118. The 75.9% lead here is substantial, indicating that the Intel processor is significantly better equipped for scientific computing, 3D rendering, and any task that relies heavily on non-integer calculations. Similarly, in the passmark_find_prime_numbers test, a pure integer workload, the Intel part scores 83 versus the AMD's 47, a 76.6% gap that underscores the Intel core's raw throughput advantage in basic arithmetic operations.

The multi-threaded performance follows the same pattern. In passmark_multithread, the i5-13450HX scores 25084, which is 43.4% higher than the Ryzen 5 150's 17492. This is expected given the Intel chip has 10 cores and 16 threads versus the AMD's 6 cores and 12 threads. The Intel processor also wins the passmark_data_compression test decisively, posting a score of 305990 against 211289, a 44.8% lead that will be felt in file archiving and database workloads.

Single-threaded performance, often a key indicator of general responsiveness, also favors Intel, though by a smaller margin. The i5-13450HX scores 3553 in passmark_single_thread, which is 12.6% ahead of the Ryzen 5 150's 3155. While this is the narrowest win for Intel, it still confirms that the Raptor Lake core architecture has a per-core performance advantage over the older Zen 3+ design. The passmark_extended_instructions test shows a 30% Intel lead (19083 vs 14675), and passmark_integer_math shows a 33.9% Intel advantage (83209 vs 62151). In passmark_random_string_sorting, the Intel chip scores 31940, beating the AMD's 22382 by 42.7%. The passmark_data_encryption test rounds out the sweep, with Intel winning by 23.9% (16632 vs 13425).

Where Each One Wins

Based strictly on the benchmark data, the AMD Ryzen 5 150 does not win in any measured category. The Intel Core i5-13450HX is the clear winner in all 11 head-to-head benchmarks, which includes tests for physics, floating-point math, integer math, multithread, single-thread, data compression, encryption, extended instructions, and random string sorting.

However, the data does suggest distinct usage profiles based on the magnitude of the Intel advantage. For workloads that are heavily parallel and can utilize all available cores, such as video rendering or code compilation, the Intel i5-13450HX is the superior choice, with its 43.4% lead in multithreaded performance being a clear indicator. The 75.9% advantage in floating-point math also makes the Intel chip the obvious pick for 3D modeling and scientific simulation.

The AMD Ryzen 5 150, while less powerful, has a lower TDP of 35 watts compared to the Intel's 55 watts. This suggests that the AMD chip could be a more power-efficient option for systems where battery life and thermal management are the primary concerns, even if it sacrifices performance. The single-threaded gap is the smallest at 12.6%, meaning that for light, everyday tasks like web browsing or office productivity, the difference between the two processors would be less noticeable than in heavily threaded workloads.

Architecture Differences

The two processors are built on fundamentally different architectures. The Intel Core i5-13450HX uses the Raptor Lake architecture, manufactured on Intel's 10 nm process node with a die size of 257 mm². It features 10 cores and 16 threads, with a base clock of 2.40 GHz and a boost clock of 4.60 GHz. Its cache hierarchy includes 80 KB of L1 cache per core, 2 MB of L2 cache per core, and a shared 20 MB L3 cache.

The AMD Ryzen 5 150 is based on the older Zen 3+ architecture, codenamed Rembrandt-R, and is fabricated by TSMC on a more advanced 6 nm process, resulting in a smaller die size of 210 mm². It has 6 cores and 12 threads, with a higher base clock of 3.30 GHz but a slightly lower boost clock of 4.55 GHz. Its cache configuration is more modest, with 64 KB of L1 cache per core, 512 KB of L2 cache per core, and a shared 16 MB L3 cache.

Memory support is another key differentiator. The Intel chip supports both DDR4 and DDR5 memory, while the AMD chip only supports DDR5. The AMD part has a specified memory bandwidth of 76.8 GB/s, whereas the Intel part does not have a listed bandwidth figure. The Intel processor supports ECC memory, a feature absent from the AMD chip. For expansion, the Intel Raptor Lake chip offers PCIe Gen 5 with 20 lanes (CPU only), while the AMD chip offers PCIe Gen 4 with 20 lanes. Integrated graphics also differ: the Intel part has UHD Graphics 710, while the AMD part includes the more capable-sounding Radeon 660M.

The Verdict

The benchmark data is unambiguous. The Intel Core i5-13450HX is the superior processor in terms of raw performance, winning every single workload test included in the comparison. Users who need maximum compute power for tasks like 3D rendering, scientific computation, or heavy multitasking should choose the Intel chip. Its 75.9% lead in floating-point math and 86.6% lead in physics are particularly strong arguments for its selection.

However, the AMD Ryzen 5 150 is not without its merits. Its lower 35 watt TDP, compared to the Intel's 55 watt TDP, makes it a more power-efficient option. For a system designed to prioritize battery life and cool operation over peak performance, the AMD chip is the better fit. The data also shows that the single-threaded performance gap is the smallest, at 12.6%, so the AMD chip would still provide a competent experience for everyday tasks. Ultimately, the choice comes down to priorities: maximum performance for the Intel, or maximum efficiency for the AMD. The data clearly favors Intel for performance, but the AMD's efficiency profile is its distinct advantage.
