Architecture Differences

The AMD Ryzen AI Max+ 392 is built on the Zen 5 architecture under the Strix Halo codename, while the Intel Core i5-14450HX uses Raptor Lake, specifically the Raptor Lake-HX refresh. These are fundamentally different designs, and the benchmark data reflects that split.

The AMD part uses 12 cores and 24 threads, with a base clock of 3.20 GHz and a boost clock of 5.00 GHz. The Intel part uses 10 cores and 16 threads, with a base clock of 2.40 GHz and a boost clock of 4.80 GHz. The core count difference alone gives AMD a structural advantage in heavily threaded workloads, and the clock advantage reinforces it.

Cache layouts differ sharply. The AMD Ryzen AI Max+ 392 has 80 KB of L1 per core, 1 MB of L2 per core, and 64 MB of shared L3. The Intel Core i5-14450HX also has 80 KB of L1 per core, but doubles L2 to 2 MB per core, and drops to 20 MB of shared L3. The large L3 pool on the AMD side is a major factor in data-heavy tasks, while Intel's larger per-core L2 helps with latency-sensitive single-thread work, though the benchmark results do not show an Intel advantage in that area.

Memory support also diverges. The AMD Ryzen AI Max+ 392 uses LPDDR5X over a quad-channel bus, with a memory bandwidth of 256.0 GB/s. The Intel Core i5-14450HX supports DDR4 and DDR5 over a dual-channel bus, with no bandwidth figure recorded in the database. PCIe connectivity differs as well: AMD provides Gen 4 with 16 lanes, while Intel provides Gen 5 with 16 lanes.

The process nodes are not close. AMD uses a 4 nm process at TSMC, with a die size of 2x 70.6 mm². Intel uses a 10 nm process with a 257 mm² die. The integrated graphics also differ: the AMD chip includes a Radeon 8060S, while the Intel chip includes UHD Graphics 710.

The Intel part has an unlocked multiplier, meaning overclocking is possible on supported platforms, while the AMD part is locked. The AMD chip has a newer release date of 2026-01-05, compared to 2024-01-07 for the Intel chip. Both have a TDP of 55 and both are active production mobile parts. The AMD chip uses AMD Socket FP11; the Intel chip uses Intel BGA 1964.

Head-to-Head Benchmarks

The recorded head-to-head data shows a clean sweep: the AMD Ryzen AI Max+ 392 wins all 11 recorded benchmark comparisons, and the Intel Core i5-14450HX wins none.

The largest margin appears in the PassMark find prime numbers test. AMD scores 320 against Intel's 98, a delta of 226.5%. This test is heavily dependent on integer throughput and cache behavior, and the AMD design is far ahead in this workload.

The extended instructions test shows a 165.4% delta. AMD scores 45666, Intel scores 17207. This is a large gap that points to the AMD core's broader instruction handling efficiency under the Zen 5 architecture.

Random string sorting shows a 101.2% delta. AMD scores 59487, Intel scores 29565. The AMD chip more than doubles the Intel result in this memory-heavy sorting workload, which aligns with the larger L3 cache and higher memory bandwidth.

Data compression shows a 99.2% delta. AMD scores 554760, Intel scores 278538. This is the single largest raw score in the dataset, and the AMD lead here is nearly double.

Integer math shows a 94.6% delta. AMD scores 152414, Intel scores 78330. The multi-thread test shows a 91% delta, with AMD at 45231 and Intel at 23680. Physics shows a 95.7% delta, with AMD at 2887 and Intel at 1475.

Floating point math shows a 71.5% delta. AMD scores 99548, Intel scores 58037. Data encryption shows a 78.4% delta, with AMD at 27784 and Intel at 15574.

The closest result is the single-thread test. AMD scores 3927 and Intel scores 3643, a delta of 7.8%. This is the only benchmark where the two processors are in the same general range, but the AMD chip still holds the lead. The same delta appears for the duplicate singlethread entry.

The average benchmark score in the database reflects this overall gap. The AMD Ryzen AI Max+ 392 has an average score of 90541, while the Intel Core i5-14450HX has an average score of 32040. The AMD chip sits at the 96th percentile against all CPUs, while the Intel chip sits at the 82nd percentile.

The Verdict

The data in the database is unambiguous. The AMD Ryzen AI Max+ 392 outperforms the Intel Core i5-14450HX in every recorded benchmark. The average benchmark score for AMD is 90541 against 32040 for Intel, which places AMD at the 96th percentile and Intel at the 82nd percentile.

For users who need maximum multi-threaded performance, the AMD chip is the clear choice. Its 12-core, 24-thread configuration, combined with 64 MB of L3 cache and 256.0 GB/s of memory bandwidth, produces leads of 91% or more in the majority of the head-to-head tests. The Intel chip cannot match these results in any measured category.

For users who prioritize single-thread performance, the AMD chip still leads, but the margin is much smaller at 7.8%. The Intel chip, with its unlocked multiplier and Gen 5 PCIe support, may appeal to users who plan to overclock or who need the newer PCIe standard, but the recorded performance data does not show any benchmark where the Intel chip wins.

The Intel Core i5-14450HX has a lower average score and a lower percentile ranking. Its nearest rivals in the database are the Intel Core i7-13705H, the Intel Core i5-14400, the Intel Core i7-12800H, and the Intel Core i9-11900, all with average scores within a narrow band around 32040. The AMD Ryzen AI Max+ 392, by contrast, sits near the Intel Xeon 654 and the AMD Ryzen 9 9955HX, with average scores around 90717 and 91199 respectively. That puts the AMD chip in a much higher performance class.

Where Each One Wins

The AMD Ryzen AI Max+ 392 wins every recorded benchmark category. The biggest wins are in find prime numbers, extended instructions, random string sorting, and data compression, where the delta exceeds 99%. These are workloads that depend on large caches, high memory bandwidth, and strong integer throughput, all of which the AMD design provides in abundance.

The Intel Core i5-14450HX has no benchmark wins in the recorded data. Its closest result is the single-thread test, where it trails by only 7.8%. That is the only category where the Intel chip is within striking distance. Users who expect to rely on single-thread performance will still see the AMD chip ahead, but the margin is small enough that the Intel chip is not entirely outclassed in that specific workload.

The Intel chip does have some differentiating features outside the benchmark data. It supports both DDR4 and DDR5 memory, which gives platform flexibility. It also provides Gen 5 PCIe, while the AMD chip uses Gen 4. The unlocked multiplier on the Intel chip allows manual overclocking, which is not available on the AMD part. These features are not reflected in the recorded benchmark scores, but they are relevant for users who value platform-level control.

For heavy parallel workloads, the AMD Ryzen AI Max+ 392 is the stronger option in every measured category. For users who need DDR4 compatibility, Gen 5 PCIe, or an unlocked multiplier, the Intel Core i5-14450HX offers those specific attributes, but the performance data shows no workload where it comes out ahead.
