AMD Ryzen 5 7400F vs Intel Core 3 305 Comparison

The AMD Ryzen 5 7400F and the Intel Core 3 305 are two six-core processors built for different segments. The Ryzen 5 7400F, a desktop part with twelve threads, dominates multi-threaded and most single-threaded workloads. The Intel Core 3 305, a mobile processor with six threads, wins only the PassMark single-thread test by a small margin. The recorded data shows a clear split: the AMD part is for sustained compute, while the Intel part focuses on a narrow single-thread advantage with low power consumption.

Where Each One Wins

The AMD Ryzen 5 7400F wins 15 of the 17 head-to-head benchmarks. Its largest victories come in integer math, where it scores 74745 against 32295, a delta of 131.4%. Random string sorting also favors the AMD chip heavily: 35096 versus 17623, a 99.1% difference. Data compression shows a 97.5% gap, with scores of 289999 and 146857. These results indicate that the Ryzen 5 7400F is built for heavy computational tasks, multithreaded rendering, and data-intensive workloads.

The Intel Core 3 305 wins two benchmarks, both measuring single-thread performance. It scores 3977 in PassMark single-thread, while the AMD part scores 3689, a delta of -7.2%. This is a modest edge, but it is the only area where the Intel chip leads. In Cinebench R23 single-core, the AMD processor still wins with 3072 versus 1852, a 65.9% difference. The Intel part’s single-thread win appears isolated to the PassMark methodology, not a general trend.

For floating-point math, the gap narrows considerably. The AMD Ryzen 5 7400F scores 45799, while the Intel Core 3 305 scores 42284, a delta of only 8.3%. This is the closest contest in the entire dataset. For physics, the AMD chip leads 1660 to 1233, a 34.6% margin. The overall pattern is consistent: the Ryzen 5 7400F delivers strong multi-core performance, while the Core 3 305 offers a slight single-thread advantage in one specific test.

Architecture Differences

The two processors use fundamentally different designs. The AMD Ryzen 5 7400F is based on Zen 4 architecture with the Raphael codename, fabricated on a 5 nm process at TSMC. It has 6,570 million transistors on a 71 mm² die. The Intel Core 3 305 uses the Wildcat Lake codename, fabricated on a 3 nm process at Intel, with no transistor or die size data recorded. The AMD chip supports DDR5 memory with a dual-channel bus and a bandwidth of 83.2 GB/s. The Intel chip supports DDR5 and LPDDR5X memory, but uses a single-channel bus with 59.7 GB/s bandwidth.

Cache configurations differ significantly. The AMD Ryzen 5 7400F has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 32 MB of shared L3 cache. The Intel Core 3 305 has 192 KB of L1 cache total, 2.5 MB of L2 cache, and 6 MB of shared L3 cache. The AMD part has a larger L3 cache by a factor of over five, which contributes to its strong performance in data-heavy workloads like compression and sorting.

The AMD processor uses AMD Socket AM5 and has 24 PCIe Gen 5 lanes, while the Intel chip uses Intel BGA 1516 and has 6 PCIe Gen 4 lanes. The AMD part supports ECC memory, the Intel part does not. The Intel Core 3 305 includes integrated graphics, specifically Intel Xe3 Graphics with 1 Xe core, while the AMD Ryzen 5 7400F has no integrated graphics. The base clock of the AMD chip is 3.70 GHz with a boost of 4.70 GHz; the Intel chip has a base clock of 1.50 GHz and a boost of 4.30 GHz. The AMD part has an unlocked multiplier, the Intel part does not.

The Verdict

The benchmark data indicates that the AMD Ryzen 5 7400F is the stronger processor for nearly every measured workload. It leads in all Cinebench tests, both multicore and singlecore, with deltas of approximately 66%. Its advantages in integer math, data compression, and random string sorting are particularly large, suggesting it handles complex calculations and data manipulation far more efficiently. The AMD part also has a higher average benchmark score of 32750 against 18302 for the Intel chip, placing it in the 83rd percentile of all CPUs versus the 72nd percentile for the Intel part.

The Intel Core 3 305 is the better choice only for the specific PassMark single-thread test, where it leads by 7.2%. Its lower TDP of 15 watts, compared to 65 watts for the AMD part, suggests it is designed for mobile or low-power systems. The Intel chip also includes integrated graphics, which makes it suitable for systems without a discrete GPU. The AMD processor requires a separate graphics card but offers significantly more performance across the board.

For a desktop system focused on rendering, compilation, or data processing, the AMD Ryzen 5 7400F is the clear choice. Its 12 threads and large cache make it far more capable in multithreaded scenarios. For a mobile device where power efficiency and integrated graphics matter more than raw compute, the Intel Core 3 305 has a role. The data shows no middle ground: the AMD part dominates 15 benchmarks, the Intel part wins 2.
