AMD Ryzen AI 9 365 vs Intel Core i5-14450HX Comparison

Head-to-Head Benchmarks

The benchmark data delivers a decisive verdict: the AMD Ryzen AI 9 365 wins 13 of the 15 recorded comparisons, while the Intel Core i5-14450HX takes only 2. The average benchmark score reinforces this split, with the AMD part posting 40048 against Intel's 32040, a gap of roughly 25 percent. The AMD processor also sits at the 87th percentile among all CPUs, while the Intel chip lands at the 82nd percentile.

The largest single victory for the AMD Ryzen AI 9 365 comes in PassMark extended instructions, where it scores 25113 versus 17207, a 45.9 percent advantage. This indicates substantially stronger handling of advanced instruction sets, which matters for workloads that use SIMD or specialized compute paths. The next biggest win is in Cinebench R15 multi-core, where AMD scores 2842 against Intel's 2026, a 40.3 percent lead. That older Cinebench version tends to favor higher thread counts and efficient scheduling, and the AMD chip's 20 threads versus Intel's 16 threads likely drives much of that gap.

PassMark integer math shows AMD ahead by 30 percent (101831 versus 78330), and PassMark data compression shows a 27.3 percent lead (354510 versus 278538). The AMD chip also wins PassMark random string sorting by 33.4 percent (39447 versus 29565), and PassMark multithread by 24.4 percent (29467 versus 23680). These results collectively point to a consistent throughput advantage across memory-heavy and integer-heavy tasks.

The AMD processor also leads in single-threaded PassMark tests, scoring 3841 versus 3643, a 5.4 percent edge. That result appears twice in the database under two test names (passmark_single_thread and passmark_singlethread), both recording identical scores. In Cinebench R15 single-core, AMD leads by 6.3 percent (303 versus 285). Smaller AMD wins include PassMark floating point math at 8.2 percent (62802 versus 58037), PassMark physics at 15.5 percent (1704 versus 1475), PassMark find prime numbers at 19.4 percent (117 versus 98), and PassMark data encryption at 17.5 percent (18297 versus 15574).

The Intel Core i5-14450HX secures its two wins in Cinebench R23. In single-core, Intel scores 2838 against AMD's 1992, a 29.8 percent advantage. That is the largest single-test margin in either direction. In multi-core R23, Intel scores 20108 versus 18698, a 7 percent lead. These two results show that in the newer Cinebench rendering workload, Intel's architecture delivers both higher per-core performance and better overall multi-core scaling, despite having fewer threads.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 9 365 uses the Zen 5 architecture on the Strix Point codename, built on a 4 nm process at TSMC. It belongs to the Ryzen AI 300 generation, which combines Zen 5 and Zen 5c cores. The Intel Core i5-14450HX uses Raptor Lake architecture with the Raptor Lake-HX codename, built on a 10 nm process at Intel. It is part of the Core 14th Gen series, specifically the Raptor Lake-HX Refresh generation.

Both chips have 10 cores, but thread counts differ: AMD provides 20 threads, while Intel provides 16. That means the AMD part uses simultaneous multithreading across all cores, while Intel reserves that capability for a subset of its core configuration. The base clock favors Intel at 2.40 GHz versus AMD's 2.00 GHz, but the boost clock favors AMD at 5.00 GHz versus Intel's 4.80 GHz.

Cache layouts diverge significantly. Both have 80 KB of L1 per core, but L2 differs: AMD uses 1 MB per core, Intel uses 2 MB per core. L3 also differs, with AMD offering 16 MB total and Intel offering 20 MB shared. The larger L2 and L3 on the Intel side likely contribute to its Cinebench R23 wins, particularly in single-core where cache latency and capacity matter.

Process node and die size also differ. AMD's 4 nm TSMC process yields a 233 mm² die, while Intel's 10 nm process yields a 257 mm² die. The smaller process node gives AMD a density advantage, though the database does not record transistor counts for either part.

Memory support separates the two as well. AMD supports DDR5 and LPDDR5X in a dual-channel configuration, with a recorded memory bandwidth of 89.6 GB/s. Intel supports DDR4 and DDR5 in dual-channel mode, but the database lists no memory bandwidth figure. AMD does not support ECC memory, while Intel does support ECC memory.

PCIe capabilities differ: AMD uses Gen 4 with 16 CPU lanes, Intel uses Gen 5 with 16 CPU lanes. Integrated graphics also differ, with AMD using the Radeon 880M and Intel using the UHD Graphics 710. The AMD part also carries a lower TDP of 28 watts versus Intel's 55 watts, which has implications for sustained performance in thin laptops versus thicker gaming or workstation machines.

The Verdict

The benchmark data indicates that the AMD Ryzen AI 9 365 is the stronger overall performer in the recorded tests, winning 13 of 15 head-to-head comparisons and holding a higher average benchmark score (40048 versus 32040) and a higher percentile ranking (87 versus 82). Its wins span integer math, floating point math, data compression, encryption, physics, sorting, and extended instructions. The AMD part also delivers these results at a 28 watt TDP versus Intel's 55 watts, which suggests better efficiency per watt, though the database does not record direct power consumption measurements.

The Intel Core i5-14450HX, however, owns the two most recent Cinebench R23 results. Its 29.8 percent single-core lead and 7 percent multi-core lead indicate that for rendering workloads in that specific benchmark, Intel's architecture provides a clear advantage. The Intel part also supports ECC memory and PCIe Gen 5, features absent from the AMD part.

The data supports a straightforward split: the AMD Ryzen AI 9 365 is the better choice for general compute, data processing, and mixed workloads, while the Intel Core i5-14450HX is preferable for Cinebench-style rendering tasks and for systems requiring ECC memory or PCIe Gen 5 connectivity.

Where Each One Wins

The AMD Ryzen AI 9 365 wins in the majority of compute categories. Its 40.3 percent lead in Cinebench R15 multi-core and 24.4 percent lead in PassMark multithread show strong parallel throughput. The 30 percent advantage in integer math and 27.3 percent advantage in data compression point to productivity tasks like compilation, spreadsheet calculations, and file archiving. The 45.9 percent lead in extended instructions makes it suitable for scientific computing, cryptography, and multimedia encoding that uses advanced CPU instruction sets. The 17.5 percent encryption win and 19.4 percent prime number win reinforce its strength in security-related and mathematical workloads.

The Intel Core i5-14450HX wins in the two Cinebench R23 tests. Its 29.8 percent single-core lead suggests better raw per-core performance in that benchmark, which translates to applications that depend heavily on single-threaded responsiveness. Its 7 percent multi-core lead in the same benchmark shows that even with fewer threads, its core design and larger caches deliver superior rendering performance in that specific workload. The Intel part also offers ECC memory support and PCIe Gen 5, which are relevant for systems requiring data integrity features or higher-bandwidth peripheral connectivity.

The database records no wins for Intel in PassMark tests. Every PassMark category goes to AMD, including single-thread (5.4 percent), floating point math (8.2 percent), physics (15.5 percent), and random string sorting (33.4 percent). Overall, the AMD processor delivers more consistent wins across a broader range of workloads, while the Intel processor excels in one specific benchmark family.
