AMD Ryzen AI 7 345 vs Intel Core i5-14400F Comparison

Head-to-Head Benchmarks

The head-to-head data paints a lopsided picture. The Intel Core i5-14400F wins 13 of the 15 recorded comparisons, while the AMD Ryzen AI 7 345 takes only 2. The scale of Intel's victories is substantial. In Cinebench R23 multi-core, the Intel part scores 21,645 against 11,461 for the AMD, a delta of -47.1%. That is nearly double the multi-threaded rendering throughput. The single-core Cinebench R23 result follows a similar pattern: Intel leads with 3,055 versus 1,818, a -40.5% gap. These are not marginal differences; they represent a full performance tier of separation in CPU-bound workloads.

The pattern persists across the Passmark suite. Data compression shows Intel at 315,521 versus AMD's 237,484 (-24.7%). Data encryption: 16,949 versus 11,814 (-30.3%). Floating point math: 61,319 versus 42,621 (-30.5%). Integer math: 81,524 versus 63,475 (-22.1%). Physics: 1,523 versus 1,089 (-28.5%). Even extended instructions, often a relative strength for newer architectures, favor Intel by -14.7% (19,937 versus 17,003). Find prime numbers shows Intel at 86 versus 62 (-27.9%). Random string sorting: 32,680 versus 25,435 (-22.2%). Multithread overall: 25,470 versus 19,927 (-21.8%). The Cinebench R15 results echo the R23 data: multi-core at 2,181 versus 1,712 (-21.5%), single-core at 307 versus 271 (-11.7%).

The AMD processor's only wins come in the two identical Passmark single-thread entries, where it scores 3,875 against Intel's 3,701, a 4.7% advantage. This is a meaningful but isolated result. It suggests the Zen 5 architecture has a per-thread efficiency edge, but that edge does not translate into broader application victories. The average benchmark score in the database reflects this overall split: Intel sits at 32,279 with a -47.1% score in the worst head-to-head test, while AMD's average is 29,461, and its percentile rank among all CPUs is 81 versus Intel's 83.

Architecture Differences

The two processors come from fundamentally different design schools. The AMD Ryzen AI 7 345 is built on TSMC's 4 nm process node and uses the Krackan Point codename, part of the Ryzen AI 300 generation with Zen 5 and Zen 5c cores. It packs 6 cores and 12 threads. The Intel Core i5-14400F is a Raptor Lake Refresh part on Intel's 10 nm process, using the Raptor Lake-R architecture, and offers 10 cores with 16 threads. The core count disparity alone explains much of the multi-threaded benchmark gap, but the architectural choices go deeper.

Cache layouts differ significantly. The AMD chip provides 80 KB of L1 per core, 1 MB of L2 per core, and only 4 MB of L3 cache. The Intel processor also has 80 KB of L1 per core, but increases L2 to 1.25 MB per core and offers 20 MB of shared L3. That 16 MB difference in L3 is substantial for workloads that repeatedly access the same data sets. The Intel part also has a larger die at 215 mm², while the AMD die size is not recorded in the database.

Memory support diverges. The AMD chip uses DDR5 and LPDDR5X with a dual-channel bus and a recorded memory bandwidth of 89.6 GB/s. The Intel part supports both DDR4 and DDR5 on a dual-channel bus, but no memory bandwidth figure is listed for it. This means the Intel chip has legacy compatibility options that the AMD part lacks. ECC memory is supported on the Intel processor but not on the AMD. PCIe connectivity also differs: the Intel chip uses Gen 5 with 16 CPU-only lanes, while the AMD part uses Gen 4 with 14 CPU-only lanes. The Intel chip thus offers both newer PCIe generation and more lanes.

Integrated graphics separate the two as well. The AMD Ryzen AI 7 345 includes a Radeon 840M iGPU, making it a complete mobile processor package. The Intel Core i5-14400F has no integrated graphics ("N/A"), which is typical for an F-series desktop part. The market segments confirm this: AMD is a mobile part on Socket FP8 with a 28 W TDP, while Intel is a desktop part on Socket 1700 with a 65 W TDP. The release dates are close: Intel on 2024-01-07, AMD on 2025-01-14. Neither has an unlocked multiplier.

The Verdict

The data is unambiguous for multi-threaded and most single-threaded workloads: the Intel Core i5-14400F is the faster processor. Its 47.1% lead in Cinebench R23 multi-core and 40.5% lead in R23 single-core suggest that any CPU-bound rendering, compilation, or simulation task will complete substantially faster on the Intel part. The Passmark suite confirms this across the board, with Intel leading by margins ranging from 14.7% (extended instructions) to 30.5% (floating point math). The database percentile ranks align: Intel at 83rd percentile among all CPUs versus AMD at 81st.

The AMD Ryzen AI 7 345 does hold a 4.7% lead in Passmark single-thread performance (3,875 versus 3,701). This indicates that for lightly threaded workloads where a single core is the bottleneck, the AMD chip has a slight efficiency advantage. However, this one win does not offset the broader pattern. In every other recorded metric, Intel wins, and often by a wide margin. The AMD part also brings integrated graphics, a lower 28 W TDP, and a newer 4 nm process, but these features do not translate into benchmark victories. The launch MSRP for the Intel part is $196, stated once here for reference. The AMD part has no recorded launch MSRP.

Where Each One Wins

The Intel Core i5-14400F is the clear winner for multi-threaded workloads. Its 10 cores and 16 threads, combined with 20 MB of shared L3 cache, deliver a 47.1% advantage in Cinebench R23 multi-core over the AMD chip's 6 cores and 12 threads. The Passmark multithread test confirms this with a 21.8% lead. Any task that scales across cores, such as video rendering, 3D modeling, batch image processing, or software compilation, will favor the Intel part. The data compression and encryption tests also favor Intel by 24.7% and 30.3% respectively, indicating that archive management and secure data handling are strong areas for the Intel chip.

The AMD Ryzen AI 7 345 wins only the Passmark single-thread test, with a 4.7% margin. This suggests that for applications that are strictly single-threaded, such as legacy software or certain scripting workloads, the AMD chip offers slightly better per-core throughput. However, even in Cinebench R23 single-core, Intel leads by 40.5%, which complicates the picture. The AMD win appears specific to the Passmark workload, not a general single-thread superiority.

For integrated graphics needs, the AMD chip is the only option with a Radeon 840M. The Intel F-series part has no iGPU, so a discrete graphics card is mandatory. The AMD part is also the more power-efficient choice on paper, with a 28 W TDP versus Intel's 65 W, and it uses a newer 4 nm process. These factors do not show up in raw benchmark scores but matter for system design. For desktop users with a dedicated GPU, the Intel part's multi-threaded dominance is decisive. For mobile or low-power systems requiring an iGPU, the AMD part holds the only viable position.
