The Intel part also occupies a higher percentile position among all CPUs in single-threaded performance, while the AMD part holds a higher overall average benchmark score. The data suggests the Intel Core 3 305 is the better choice for floating-point heavy workloads and tasks that depend on high single-core speed, while the AMD Ryzen 3 PRO 5355G is preferable for integer-heavy and compression workloads. The AMD part also features ECC memory support, which the Intel part lacks.

The Verdict

The benchmark results indicate a clear split in workload strengths. The Intel Core 3 305 delivers a 22.2% higher score in the passmark single-thread test, recording 3977 against the AMD part's 3096. This advantage extends to floating-point math, where the Intel part scores 42284 versus 25245, a 40.3% gap. For users running applications that depend on single-core speed or heavy floating-point calculations, the Intel Core 3 305 is the stronger choice based on the data.

The AMD Ryzen 3 PRO 5355G, however, holds the higher average benchmark score at 27382, compared to the Intel part's 18302. This discrepancy comes from the AMD part's massive lead in passmark integer math, where it scores 45910 versus 32295, a 42.2% advantage. The AMD part also leads in data compression, scoring 168041 against 146857, a 14.4% difference. The AMD part's 79th percentile ranking among all CPUs versus the Intel part's 72nd percentile further supports its overall standing in the database.

The Intel Core 3 305 carries a launch MSRP of $309. The AMD part has no recorded launch MSRP. The Intel part also shows a much higher physics score, 1233 versus 701, a 43.1% lead. The AMD part wins only 3 of 11 head-to-head tests, but those wins are substantial in magnitude. The verdict from the data is that the Intel Core 3 305 suits workloads prioritizing single-thread and floating-point performance, while the AMD Ryzen 3 PRO 5355G suits integer-heavy and data-compression tasks, with the added benefit of ECC memory support for stability-sensitive environments.

Head-to-Head Benchmarks

The largest single win for the AMD Ryzen 3 PRO 5355G comes in passmark integer math. The AMD part scores 45910, while the Intel Core 3 305 scores 32295, giving the AMD part a 42.2% lead. This is the widest margin in either direction across all recorded tests. The AMD part also wins passmark data compression with a score of 168041 against 146857, a 14.4% difference, and passmark random string sorting with 18819 against 17623, a 6.8% lead.

The Intel Core 3 305 dominates the remaining categories. Its most significant win is in passmark find prime numbers, scoring 115 against the AMD part's 36, a 68.7% advantage. The Intel part also leads in floating-point math by 40.3% (42284 versus 25245) and in physics by 43.1% (1233 versus 701). The single-thread tests show a 22.2% lead for Intel, with scores of 3977 versus 3096. The Intel part wins multithread by 9.1% (15439 versus 14033), extended instructions by 11.9% (13543 versus 11935), and data encryption by 6.6% (11019 versus 10288).

The pattern in the data is consistent. The AMD part excels in integer arithmetic and compression tasks, while the Intel part excels in floating-point, encryption, and prime number calculations. The multithread score for the Intel part is notable because the AMD part has 8 threads versus 6 for Intel, yet Intel still wins by 9.1%. This suggests that the Intel part's higher single-thread performance carries over to its multithread result, despite having fewer threads.
