The Verdict

The benchmark database shows a complete sweep for the AMD Ryzen 5 7500X3D. It wins all 11 recorded head-to-head tests, with the largest margin in prime number finding at 718.5% ahead, and the smallest in single-thread performance at 62.3% ahead. The 7500X3D sits in the 89th percentile of all CPUs, while the N355 ranks in the 68th percentile. The average benchmark score for the AMD part is 44573, compared to 13492 for the Intel part, a difference of roughly 3.3 times. This is not a close contest; the 7500X3D is in a different performance class entirely.

The Intel Core 3 N355 is designed for a different purpose. Its 15 TDP, single-channel memory, and mobile BGA socket place it in low-power laptops and compact systems. Its nearest rivals include the Intel Core i3-12100F and the Intel Core i5-9500, with average scores of 13494 and 13452 respectively, showing it is competitive within its own segment. However, against the 7500X3D, the data offers no evidence of any workload where the N355 pulls ahead.

Desktop users with demanding workloads should choose the AMD Ryzen 5 7500X3D. Mobile users prioritizing low power consumption over performance should consider the Intel Core 3 N355, but not for any benchmark win. The 7500X3D's score of 25047 in Passmark multithread is over 2.4 times the N355's 10174, confirming the desktop part's dominance in parallel workloads.

The AMD part also dominates in memory-intensive tasks. Its data compression score of 271649 is 131.3% higher than the Intel part's 117435. The 96 MB of L3 cache and dual-channel memory bandwidth of 83.2 GB/s likely contribute to this performance. The multithread score of 25047 versus 10174 confirms the AMD part handles parallel workloads much more effectively.

The Intel Core 3 N355 wins no benchmark tests in this comparison. Its strengths lie outside the performance data, specifically in its 15 TDP and mobile form factor. The single-channel memory and BGA socket indicate it is meant for low-power devices where performance is secondary to efficiency. The data shows it is competitive with processors like the Intel Core i3-12100F and Intel Core i5-9500, but it cannot match the AMD Ryzen 5 7500X3D in any recorded metric.

For desktop users with heavy compute needs, the AMD Ryzen 5 7500X3D is the clear choice based on the database results. For mobile users who need a low-power processor, the Intel Core 3 N355 serves that segment, but it offers no performance advantages in the head-to-head data. The 89th percentile ranking of the AMD part versus the 68th percentile of the Intel part summarizes the performance hierarchy.
