The Verdict

The recorded data shows a decisive performance advantage for the AMD Ryzen 7 8840HX. The AMD processor holds a 94th percentile ranking among all CPUs, while the Intel Core i5-14501E sits at the 50th percentile. The AMD part has an average benchmark score of 71,797, while the Intel part has an average benchmark score of 0 in the database, meaning no benchmark results are recorded for it.

For multi-threaded workloads, the AMD processor is the clear choice. Its 12 cores and 24 threads, combined with 64 MB of L3 cache, deliver a Cinebench R23 multicore score of 25,265. The Intel part has no recorded multicore score, but its 6 cores and 12 threads place it in a different performance tier. The AMD processor also leads in PassMark multithread with a score of 41,732.

For single-threaded workloads, the Intel processor has a higher boost clock (5.20 GHz vs. 5.10 GHz), but no single-thread benchmark scores are recorded for it. The AMD processor achieves a Cinebench R23 single-core score of 1,857 and a PassMark single-thread score of 3,958. Without Intel data, the comparison cannot be quantified, but the AMD processor's scores place it in the upper tier of single-thread performance.

The Intel Core i5-14501E offers ECC memory support and DDR4 compatibility, which are useful for specific reliability-focused desktop builds. However, the AMD processor's benchmark dominance, higher core count, larger cache, and mobile platform positioning make it the stronger performer in the database.
