Where Each One Wins

The Intel Core i9-14901E wins 16 of the 17 head-to-head benchmark comparisons. Its advantages span synthetic multi-threaded workloads, physics calculations, integer math, floating-point math, prime number finding, data encryption, and random string sorting. The Intel part also leads in every Cinebench test, both single-core and multi-core, across R15, R20, and R23 versions.

The AMD Ryzen 5 8400F wins exactly one head-to-head test: PassMark extended instructions. This test measures the processor's handling of specialized instruction sets, and the AMD part scores 28.6 percent higher than Intel in this specific area. This suggests the Zen 4 architecture's instruction execution efficiency delivers a measurable edge for workloads that rely on extended instruction paths.

For general productivity, the Intel part dominates. Multi-threaded Cinebench R23 shows 25753 for Intel versus 20851 for AMD, a 19 percent gap. PassMark multithread shows 30298 for Intel versus 24389 for AMD, a 19.5 percent gap. These results indicate that the Intel processor's additional two cores and four threads, combined with its higher boost clock, translate into consistent multi-threaded advantages.

For single-threaded responsiveness, the Intel part also wins. The 5.60 GHz boost clock versus 4.70 GHz gives Intel a 19 percent lead in single-core Cinebench R23 and a 15.4 percent lead in PassMark single-thread. The AMD part, however, has a 28.6 percent lead in extended instructions, which could matter for specific scientific or computational workloads that use those instructions.

The Verdict

The benchmark data clearly favors the Intel Core i9-14901E for the vast majority of workloads. It wins 16 of 17 head-to-head tests, including every Cinebench test, every PassMark math test, and most PassMark data-processing tests. The Intel part's higher boost clock, larger cache, and additional cores give it consistent leads ranging from 0.2 percent in data compression to 56.2 percent in physics.

The AMD Ryzen 5 8400F has a clear niche: extended instructions. Its 28.6 percent lead in that specific benchmark suggests the Zen 4 architecture executes certain specialized instruction sequences more efficiently. For software that relies heavily on those instructions, the AMD part could be the better choice. Additionally, the AMD chip runs on a 4 nm process versus Intel's 10 nm, which shows in its smaller die size and higher base clock.

The Intel processor also offers features the AMD part lacks: ECC memory support, integrated UHD Graphics 770, PCIe Gen 5, and support for both DDR4 and DDR5 memory. The AMD processor offers an unlocked multiplier and DDR5 support with a recorded memory bandwidth of 83.2 GB/s.

For users prioritizing multi-threaded rendering, physics simulation, or heavy integer and floating-point math, the Intel Core i9-14901E is the stronger part based on the recorded data. For users running specialized workloads that depend on extended instruction sets, the AMD Ryzen 5 8400F shows a measurable advantage. The overall percentile ranking confirms this split: Intel sits at the 86th percentile of all CPUs, while AMD sits at the 77th percentile.

The Intel part's nearest rivals include the AMD Ryzen AI 9 HX 370 with an average score of 37904 (0 percent delta), the AMD Ryzen 7 9700X at 37943 (-0.1 percent), and the Intel Core 5 211E at 37829 (0.2 percent). The AMD part's nearest rivals include the AMD Ryzen 5 7500F at 24964 (0.2 percent) and the Intel Core i7-13620H at 24911 (0.4 percent). These adjacent scores place each processor within a tight competitive cluster, but the Intel part operates in a higher performance tier overall.
