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

Head-to-Head Benchmarks

The benchmark comparison between the AMD Ryzen AI 7 345 and the Intel Core i5-14400 is decisively lopsided, with Intel claiming 13 of the 15 recorded tests. The largest margin appears in Cinebench R23 multicore, where the Intel Core i5-14400 scores 21,315 against the AMD Ryzen AI 7 345's 11,461, a delta of 46.2 percent. That is the single biggest gap in the entire dataset, indicating a substantial difference in sustained multi-threaded throughput. Cinebench R15 multicore tells a similar story, with Intel ahead by 20.3 percent (2,148 versus 1,712), while PassMark multithread shows a 20.5 percent advantage for Intel (25,080 versus 19,927).

Single-core results are mixed. In Cinebench R15 single-core, Intel leads by 10.6 percent (303 versus 271), and in Cinebench R23 single-core the gap widens to 39.6 percent (3,009 versus 1,818). However, PassMark single-thread flips the outcome: the AMD Ryzen AI 7 345 scores 3,875, which is 3.6 percent higher than Intel's 3,741. This split suggests the two processors handle single-threaded workloads differently depending on the benchmark methodology. The AMD part wins both PassMark single-thread entries (the database lists the same result twice under slightly different test names), giving it exactly two wins total.

The remaining PassMark suite is uniformly favorable to Intel. Data compression shows Intel ahead by 24.6 percent (314,995 versus 237,484). Data encryption favors Intel by 29.4 percent (16,731 versus 11,814). Floating point math, often a good indicator of raw compute capability, gives Intel a 30.8 percent edge (61,549 versus 42,621). Integer math is closer but still Intel-favored at 22.6 percent (82,017 versus 63,475). Extended instructions show a 14.2 percent Intel lead (19,816 versus 17,003), which is the narrowest margin outside the single-thread PassMark result. Prime number finding, physics, and random string sorting all land in a tight band of Intel advantages between 21.4 and 22.5 percent.

The overall averages reflect this dominance. The Intel Core i5-14400 posts an average benchmark score of 32,115, while the AMD Ryzen AI 7 345 averages 29,461. The percentile rankings are nearly identical, with Intel at the 82nd percentile and AMD at the 81st, meaning both processors sit close to each other in the broader database distribution despite the Intel lead in most individual tests. The nearest rivals for the AMD part include the AMD Ryzen 7 3800X (average score 29,447, delta 0 percent) and the Intel Core i5-13500HX (29,270, delta 0.7 percent). The Intel Core i5-14400 sits near the Intel Core i7-12800H (32,121, delta 0 percent) and the Intel Core i7-13705H (32,076, delta 0.1 percent).

The Verdict

The data points to a straightforward conclusion for raw throughput: the Intel Core i5-14400 is the stronger processor in nearly every measured category. Its 46.2 percent lead in Cinebench R23 multicore is the standout result, and its consistent advantages across compression, encryption, math, and physics workloads indicate a processor that simply sustains higher output under load. The AMD Ryzen AI 7 345 does not win any multi-threaded test in the database. Its only recorded wins are the two PassMark single-thread entries, and even there the margin is modest at 3.6 percent.

The Intel part also wins both Cinebench single-core tests, including a 39.6 percent margin in R23 single-core. That is a large gap for a workload that typically favors architectural efficiency. The AMD processor's PassMark single-thread win suggests it has competitive per-thread capability in some conditions, but the Cinebench results undercut that narrative. The AMD Ryzen AI 7 345 is a 28-watt mobile part, while the Intel Core i5-14400 is a 65-watt desktop processor. That power class difference explains much of the performance split, but the database records only the benchmark outcomes, not power-normalized efficiency.

For a user prioritizing multi-threaded compute, the Intel Core i5-14400 is the clear choice. For a user prioritizing a single PassMark single-thread metric, the AMD part has a narrow edge. The overall average benchmark score also favors Intel by roughly 9 percent (32,115 versus 29,461). The AMD processor's position near the AMD Ryzen 7 3800X and Intel Core i5-13500HX in its nearest rival list suggests it competes at a lower performance tier, while the Intel part aligns with the Intel Core i7-12800H and Intel Core i9-11900.

Where Each One Wins

The AMD Ryzen AI 7 345 wins only in PassMark single-thread performance, with a score of 3,875 against Intel's 3,741. This indicates that in at least one single-threaded test methodology, the AMD architecture delivers slightly higher per-core performance. The win is small, just 3.6 percent, but it is consistent across both recorded entries for that test. No other benchmark in the database favors the AMD processor.

The Intel Core i5-14400 wins every other recorded test. Its advantages cluster in three groups. First, heavy multi-threaded synthesis: Cinebench R15 multicore (20.3 percent), Cinebench R23 multicore (46.2 percent), and PassMark multithread (20.5 percent). Second, computational math: floating point (30.8 percent), integer (22.6 percent), and prime number finding (22.5 percent). Third, data manipulation: compression (24.6 percent), encryption (29.4 percent), and random string sorting (21.4 percent). The Intel part also wins the Cinebench single-core tests, with margins of 10.6 percent in R15 and 39.6 percent in R23.

The pattern suggests the Intel Core i5-14400 is the more versatile processor across the benchmark suite. Its wins span every category except the single PassMark single-thread test. The AMD Ryzen AI 7 345, by contrast, shows a narrow single-thread strength but does not translate that into victories in any other workload.
