The Verdict

The data points to a clear division of roles. The AMD Ryzen 9 9900X dominates multi-threaded performance, with a Cinebench R23 multi-core score of 32,172 versus 18,161 for the Intel Core i5-14401E, a 77.1% advantage. The AMD part also wins Cinebench R15 multi-core by 173.7% and R15 single-core by 36.8%. Its average benchmark score of 57,498 places it in the 92nd percentile of all CPUs, with nearest rivals including the Intel Core i9-14900 at a 1.1% deficit and the AMD EPYC 9015 at a 0.1% deficit.

The Intel Core i5-14401E counters with a 12.1% win in Cinebench R23 single-core, scoring 2,564 against 2,253. However, its average benchmark score of 5,253 puts it in the 60th percentile, with nearest rivals like the Intel Core i7-11700B at a 0.2% deficit and the Intel Core i9-10850K at a 0.2% deficit. The Intel part also runs at a 65 TDP against the AMD part's 120 TDP, making it the lower-power option.

For users who need maximum multi-threaded throughput, the Ryzen 9 9900X is the stronger choice by a wide margin. For workloads that prioritize single-thread performance and lower power draw, the Core i5-14401E holds a specific advantage in one benchmark, though its overall scores trail significantly.

Specification Differences

The two processors differ across nearly every core specification. The AMD Ryzen 9 9900X has 12 cores and 24 threads, a base clock of 4.40 GHz, and a boost clock of 5.60 GHz. The Intel Core i5-14401E has 6 cores and 12 threads, a base clock of 2.50 GHz, and a boost clock of 4.70 GHz.

TDP is a major differentiator: the AMD part is rated at 120, while the Intel part is rated at 65. The AMD processor uses a 4 nm process from TSMC and a dual-chiplet design with 2x 70.6 mm² die size, containing 16,630 million transistors. The Intel processor uses a 10 nm process from Intel with a 215 mm² die size; no transistor count is recorded.

Cache and memory support also diverge. The AMD part has 64 MB of L3 cache and 1 MB of L2 per core, with support for DDR5 only and a memory bandwidth of 89.6 GB/s.

Head-to-Head Benchmarks

The head-to-head comparison in the database records four tests. The AMD Ryzen 9 9900X wins three of them, with margins ranging from substantial to overwhelming.

In Cinebench R15 multi-core, the AMD part scores 5,008 against 1,830 for the Intel part, a 173.7% advantage. This is the largest recorded gap between the two processors. The AMD part's 12 cores and 24 threads provide a massive parallel throughput advantage over the Intel part's 6 cores and 12 threads.

In Cinebench R15 single-core, the AMD part scores 353 against 258, a 36.8% win. This shows that the Zen 5 architecture delivers higher per-core performance in this older rendering test, despite the Intel part's higher R23 single-core score.

In Cinebench R23 multi-core, the AMD part scores 32,172 against 18,161, a 77.1% advantage. This confirms the multi-threaded dominance seen in R15, though the margin is smaller due to the newer test's scaling characteristics.

The Intel Core i5-14401E wins the fourth test: Cinebench R23 single-core, scoring 2,564 against 2,253 for the AMD part, a 12.1% victory. This is the only benchmark where the Intel part leads, and it indicates that Raptor Lake's high boost clock of 4.70 GHz, combined with its architecture, gives it an edge in this specific single-threaded workload.

The wins break down as 3 for the AMD part and 1 for the Intel part.

Where Each One Wins

The AMD Ryzen 9 9900X wins in any scenario that scales with core count and thread count. Its 24 threads deliver a 173.7% lead in Cinebench R15 multi-core and a 77.1% lead in Cinebench R23 multi-core. The 64 MB of L3 cache and 89.6 GB/s memory bandwidth support data-heavy workloads, while the 24 Gen 5 PCIe lanes provide more connectivity headroom. The unlocked multiplier also allows overclocking, a feature the Intel part lacks.

The Intel Core i5-14401E wins in the specific case of Cinebench R23 single-core, where it leads by 12.1%. This makes it the better option for workloads that rely heavily on single-threaded performance in that particular test. Its 65 TDP also means it draws less power under load, which can simplify cooling requirements and lower operating costs in sustained use. The support for both DDR4 and DDR5 memory gives platform flexibility for users with existing DDR4 modules.

The average benchmark scores place the AMD part at 57,498, ranking in the 92nd percentile of all CPUs, while the Intel part scores 5,253, ranking in the 60th percentile. The AMD part's nearest rivals are all high-end server and desktop parts, including the Intel Core i9-14900 at a 1.1% deficit. The Intel part's nearest rivals are older desktop parts, including the Intel Core i9-10850K at a 0.2% deficit. This ranking gap confirms that the Ryzen 9 9900X operates in a higher performance class, while the Core i5-14401E sits in a more modest tier.
