AMD Ryzen AI Max+ 392 vs Intel Core i5-14400F Comparison

Architecture Differences

The AMD Ryzen AI Max+ 392 and Intel Core i5-14400F represent fundamentally different design philosophies. The AMD part is built on the Zen 5 architecture using the Strix Halo codename, manufactured on a 4 nm process at TSMC. It features 12 cores and 24 threads, with a base clock of 3.20 GHz and a boost clock of 5.00 GHz. The Intel Core i5-14400F uses the Raptor Lake architecture, specifically the Raptor Lake Refresh generation, built on a 10 nm process at Intel. It offers 10 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 4.70 GHz.

Cache configurations differ notably. Both processors allocate 80 KB of L1 cache per core. The AMD chip provides 1 MB of L2 cache per core, while Intel offers 1.25 MB per core. The shared L3 cache is where the gap widens substantially: AMD packs 64 MB, while Intel provides 20 MB. This larger AMD cache pool directly supports the processor's higher sustained throughput in memory-intensive workloads.

Memory subsystems also split along architectural lines. The Ryzen AI Max+ 392 supports LPDDR5X memory over a quad-channel bus, delivering 256.0 GB/s of memory bandwidth. The Intel part supports both DDR4 and DDR5 across a dual-channel bus, with no bandwidth figure recorded in the database. PCIe connectivity differs as well: AMD provides Gen 4 with 16 lanes (CPU only), while Intel provides Gen 5 with 16 lanes (CPU only).

Integrated graphics separate these two parts completely. The AMD processor carries a Radeon 8060S GPU, while the Intel Core i5-14400F has no integrated graphics at all. Both support ECC memory, and both have locked multipliers, meaning no overclocking through multiplier adjustment. The AMD chip uses AMD Socket FP11, targeting the mobile market segment, while Intel uses Socket 1700 for desktop systems. Release dates are roughly two years apart: the AMD part arrived on 2026-01-05, and the Intel part on 2024-01-07.

The Verdict

The benchmark data delivers a decisive outcome. The AMD Ryzen AI Max+ 392 wins all 11 recorded head-to-head comparisons against the Intel Core i5-14400F, with zero wins for the Intel part. The average benchmark score for the AMD processor is 90,541, placing it in the 96th percentile of all CPUs in the database. The Intel processor averages 32,279, sitting in the 83rd percentile. That is a delta of roughly 180% in average score, a gap that dwarfs the nearest rival deltas for either chip.

Looking at the nearest rivals provides context. The AMD processor's closest competitors are the Intel Xeon 654 (avg score 90,717, delta -0.2%), the AMD Ryzen 9 9955HX (avg score 91,199, delta -0.7%), and the Intel Xeon w7-2575X (avg score 88,172, delta 2.7%). The Intel Core i5-14400F's nearest rivals include the AMD Ryzen 7 PRO 8840U (avg score 32,233, delta 0.1%), the Intel Core i9-11900 (avg score 32,226, delta 0.2%), and the AMD Ryzen 7 6800HS (avg score 32,354, delta -0.2%). These rival clusters confirm that the two processors operate in entirely different performance strata.

The verdict is straightforward: the AMD Ryzen AI Max+ 392 is the superior processor on every recorded metric. Users who need maximum compute throughput, particularly in multi-threaded and SIMD-heavy workloads, should select the AMD part. The Intel Core i5-14400F remains a viable option only in scenarios where its desktop platform, dual-channel DDR4/DDR5 support, and Gen 5 PCIe connectivity are required, and where the performance deficit is acceptable. The data shows no benchmark category where the Intel part pulls ahead.

Head-to-Head Benchmarks

The AMD Ryzen AI Max+ 392 dominates every recorded benchmark comparison. The largest margin appears in passmark_find_prime_numbers, where AMD scores 320 versus Intel's 86, a 272.1% delta. This test highlights the AMD processor's exceptional integer throughput and cache efficiency. The gap is nearly as wide in passmark_extended_instructions: AMD records 45,666 against Intel's 19,937, a 129.1% advantage. This reflects the AMD part's superior SIMD and instruction-level parallelism capabilities.

The multi-threaded workloads show consistent AMD superiority. In passmark_multithread, AMD scores 45,231 versus 25,470, a 77.6% delta. Passmark_integer_math shows 152,414 against 81,524, an 87% delta. Passmark_physics records 2,887 versus 1,523, an 89.6% delta. Passmark_random_string_sorting delivers 59,487 versus 32,680, an 82% delta. These results indicate that the AMD processor's 12-core, 24-thread configuration with 64 MB L3 cache scales far better under parallel loads than Intel's 10-core, 16-thread design with 20 MB L3.

Memory and data-intensive tasks follow the same pattern. Passmark_data_compression shows AMD at 554,760 versus Intel at 315,521, a 75.8% delta. Passmark_data_encryption records 27,784 versus 16,949, a 63.9% delta. Passmark_floating_point_math delivers 99,548 versus 61,319, a 62.3% delta. The quad-channel LPDDR5X memory subsystem with 256.0 GB/s bandwidth clearly feeds the AMD processor's compute units more effectively than Intel's dual-channel DDR4/DDR5 setup.

The closest margin is in single-thread performance. AMD scores 3,927 in passmark_single_thread, while Intel scores 3,701, a 6.1% delta. This indicates that while the AMD processor holds the edge in lightly threaded tasks, the Intel part is not far behind in raw per-core speed. The AMD advantage grows as thread counts and memory bandwidth demands increase.

Where Each One Wins

The AMD Ryzen AI Max+ 392 wins in every recorded category, but the magnitude of its wins varies by workload type. The largest deltas appear in prime number finding (272.1%) and extended instructions (129.1%), suggesting that the AMD processor is particularly strong in mathematical and SIMD-heavy computations. These workloads benefit from the combination of 12 Zen 5 cores, the 64 MB L3 cache, and the high-bandwidth quad-channel memory interface.

In multi-threaded productivity tasks, the AMD processor's lead remains substantial but slightly narrower. Passmark_multithread shows a 77.6% delta, passmark_integer_math shows 87%, and passmark_physics shows 89.6%. These results indicate that the AMD part scales very well across its 24 threads, while the Intel part's 16 threads and smaller cache limit its parallel efficiency.

The Intel Core i5-14400F does not win any recorded benchmark. However, its strengths lie outside the benchmark suite. The desktop socket (Intel Socket 1700) and support for both DDR4 and DDR5 memory give it platform flexibility. The Gen 5 PCIe interface with 16 lanes provides newer I/O connectivity compared to AMD's Gen 4 implementation. The lack of integrated graphics means users must pair it with a discrete GPU, but this also reduces the processor's complexity for desktop builds.

For single-threaded tasks, the Intel part is competitive. The 6.1% delta in passmark_single_thread is the smallest gap in the entire comparison. This suggests that for lightly threaded applications, the Intel processor can deliver acceptable performance, though it still trails the AMD part.
