The Verdict

The data shows a substantial performance gap between these two processors, driven primarily by the core count difference. The AMD Ryzen 9 9955HX has 16 cores and 32 threads, while the Intel Core i5-14501E has 6 cores and 12 threads. The AMD processor also has significantly more L3 cache (64 MB versus 24 MB) and a higher boost clock (5.40 GHz versus 5.20 GHz).

The AMD Ryzen 9 9955HX ranks in the 96th percentile among all CPUs in the database, indicating it sits near the top of the performance distribution. The Intel Core i5-14501E ranks in the 50th percentile, placing it at the median of recorded CPUs.

The benchmark results for the AMD processor show strong multi-core performance. In Cinebench R23 multi-core, it scores 37159 points, and in Cinebench R15 multi-core, it scores 5905 points. The PassMark multi-thread score is 56171, and the PassMark single-thread score is 4393. The Intel Core i5-14501E has no recorded benchmark scores in the database, so direct numerical comparison is not possible from the recorded data.

However, the architectural differences alone indicate which workloads favor each processor. The AMD Ryzen 9 9955HX is designed for mobile platforms with a 55 W TDP, while the Intel Core i5-14501E is a desktop part with a 65 W TDP. The AMD processor uses the smaller 4 nm process, which suggests higher transistor density and potentially better efficiency per watt.

For users who need maximum multi-threaded throughput, the AMD Ryzen 9 9955HX is the clear choice based on its core count, cache size, and benchmark percentile. For users constrained to the Intel Socket 1700 platform, the Core i5-14501E provides a capable desktop option with 6 cores and 12 threads, though its 50th percentile ranking places it at the median of the database.

The data does not support a case where the Intel processor outperforms the AMD processor in any measured category, given that the Intel part has no recorded benchmark scores and the AMD part has a higher percentile ranking, more cores, more cache, and a higher boost clock.
