AMD Ryzen 3 5425U vs Intel Atom P5342 Comparison

Head-to-Head Benchmarks

The benchmark data for the AMD Ryzen 3 5425U and the Intel Atom P5342 reveals a clear overall winner in the recorded Cinebench R23 tests, with the Intel part taking both available head-to-head comparisons. The most significant gap appears in the multi-core test, where the Intel Atom P5342 scores 11122 compared to the AMD Ryzen 3 5425U's 5954.5. This represents a 46.5% advantage for the Intel processor, a substantial margin that underscores the raw throughput difference between the two designs in heavily threaded workloads. The data shows that the Atom P5342, with its 16 cores, leverages its core count to dominate the multi-threaded rendering workload.

In the single-core Cinebench R23 test, the margin narrows considerably but still favors the Intel Atom P5342. The Intel chip records a score of 1570, while the AMD Ryzen 3 5425U trails at 1332, resulting in a 15.2% deficit for the AMD part. While the multi-core result is a decisive victory for Intel, the single-core result is more modest, though still a clear win. The benchmark results indicate that the Intel Atom P5342 does not merely rely on core count; it also exhibits a per-core performance advantage in this specific rendering test over the Zen 3 based AMD processor.

Looking at the broader benchmark landscape from the database, the two processors occupy similar overall percentile positions. The AMD Ryzen 3 5425U sits at the 52nd percentile among all CPUs, while the Intel Atom P5342 sits just above it at the 53rd percentile. This near-identical percentile ranking suggests that, despite the Intel chip's commanding lead in the Cinebench R23 multi-core test, the overall average benchmark scores are very close. The AMD Ryzen 3 5425U has an average benchmark score of 3124, while the Intel Atom P5342 averages 3217. This difference of 93 points, or roughly 3%, is far smaller than the 46.5% gap seen in the Cinebench R23 multi-core test, indicating that the Intel chip's advantage is not uniform across all possible workloads.

The nearest rivals for each processor, as listed in the database, help contextualize these average scores. The AMD Ryzen 3 5425U's closest competitor is the AMD Ryzen 5 6600HS, with an average score of 3122, a delta of just 0.1%. Other rivals include the Intel Core i3-13100TE at 3111 (0.4% delta) and the AMD Ryzen 5 5625U at 3096 (0.9% delta). On the Intel side, the Atom P5342's nearest rivals include the AMD Ryzen 3 PRO 5350GE and the AMD Ryzen 7 4800U, both with average scores of 3218, representing a 0% delta. The Intel Core i5-1240P follows at 3202 (0.5% delta), and the Intel Core i3-13100T at 3198 (0.6% delta). These figures show that both processors are competitive with a similar tier of other chips, although the Intel Atom P5342's average score aligns it with more powerful mainstream mobile and desktop parts.

Where Each One Wins

The benchmark data demonstrates a clear split in workload applicability between these two processors. The Intel Atom P5342 is the definitive winner in the Cinebench R23 multi-core test, outperforming the AMD Ryzen 3 5425U by 46.5%. This result positions the Intel chip as the stronger choice for applications that can utilize many cores simultaneously, such as video rendering, 3D model generation, or server-side batch processing. Its 16 cores and 16 threads, combined with a 71 W TDP, suggest it is designed for sustained parallel throughput, and the recorded data confirms this strength.

Conversely, while the Intel Atom P5342 also wins the Cinebench R23 single-core test, the margin is much smaller at 15.2%. The AMD Ryzen 3 5425U, with its higher base clock of 2.70 GHz and boost clock of 4.10 GHz, is clearly more oriented towards responsive single-threaded performance. However, the data does not support a win for the AMD part in this specific test. The Ryzen 3 5425U's lower TDP of 15 W and mobile market segment suggest it is intended for power-sensitive devices where the Intel Atom P5342's 71 W TDP would be prohibitive.

The use-case split is therefore defined by the nature of the workload and the platform. For a server or workstation environment where power is less constrained and multi-threaded performance is paramount, the Intel Atom P5342 is the clear choice based on its 46.5% multi-core lead. For a mobile or power-constrained setting, the AMD Ryzen 3 5425U, with its 15 W TDP and integrated Radeon Vega 6 graphics, offers a more balanced feature set, even if it cedes raw multi-core performance to the Intel part. The database shows that the Intel Atom P5342 has no integrated graphics, making the AMD chip the only option of the two for systems requiring a built-in display output without a discrete GPU.
