AMD Ryzen 5 7400F vs Intel Core Ultra 7 155H Comparison

The AMD Ryzen 5 7400F and Intel Core Ultra 7 155H are close rivals, with average benchmark scores of 32750 and 32697 respectively, placing the AMD part a marginal 0.2% ahead. Despite this near-identical overall average, the two processors achieve their results through very different performance profiles, with the AMD chip winning 13 of the 17 head-to-head tests and the Intel chip taking the remaining 4. The data reveals a consistent split: the Ryzen 5 7400F dominates in single-threaded and most multi-threaded workloads, while the Core Ultra 7 155H counters with decisive wins in specific math-oriented tasks.

Head-to-Head Benchmarks

The largest single victory belongs to the AMD Ryzen 5 7400F in Cinebench R23 single-core, where it scores 3072 against Intel’s 1743, a 76.2% advantage. This is not an isolated case. The same pattern appears in Cinebench R15 single-core, where AMD leads 309 to 255, a 21.2% gap. Even in the newer R20 single-core test, the Ryzen wins by 4.5%, scoring 1290 over 1235. These results indicate a fundamental difference in per-core efficiency, a factor that becomes more pronounced in the R23 test than in the older R15 version.

Multi-core results are more mixed. The Ryzen 5 7400F wins Cinebench R23 multi-core decisively, scoring 21765 versus 15028, a 44.8% lead. However, the Intel chip wins Cinebench R15 multi-core, scoring 2450 against 2193, a 10.5% margin. The R20 multi-core test goes back to AMD, with a 4.4% win (9141 vs 8754). This inconsistency across Cinebench versions suggests that the Intel part scales better in the shorter, lighter R15 workload, while the AMD part’s advantage grows as the test duration and complexity increase, culminating in the massive R23 difference.

PassMark results further illuminate the divide. The AMD Ryzen 5 7400F wins PassMark single-thread by 6.4% (3689 vs 3468), and also takes PassMark multi-thread by 3.1% (25645 vs 24873). In data compression, AMD wins by 4.6% (289999 vs 277353), and in data encryption by 2.2% (16712 vs 16358). The Ryzen’s biggest PassMark win is in extended instructions, where it scores 21747 against 16456, a 32.2% margin, and in find prime numbers, where it leads 191 to 113, a 69% advantage. Random string sorting also favors AMD, 35096 to 31990, a 9.7% win.

The Intel Core Ultra 7 155H’s victories are concentrated in three PassMark arithmetic tests and one physics simulation. Its largest win is in floating point math, scoring 63703 against 45799, a 28.1% margin. It also wins integer math by 14% (86870 vs 74745) and physics by 3.9% (1727 vs 1660). These are substantial margins in the math tests, showing that the Intel architecture has a clear strength in raw computational throughput for certain instruction types, even though it loses in the more general-purpose and encryption/compression workloads.

The Verdict

The data points to a clear conclusion for most users: the AMD Ryzen 5 7400F is the stronger processor for a majority of workloads. Its 76.2% lead in Cinebench R23 single-core and 44.8% lead in R23 multi-core are the most striking figures, suggesting a major advantage in both lightly-threaded and heavily-threaded CPU-bound tasks. With 13 wins out of 17 tests, the Ryzen is the default recommendation for anyone whose work involves general-purpose computing, content creation, or application compilation, as these tasks typically rely on the single-core and multi-core strengths where AMD excels.

The Intel Core Ultra 7 155H is not without merit, but its wins are narrower in scope. Its 28.1% advantage in floating point math and 14% lead in integer math point to a specific use case: workloads that are dominated by these arithmetic operations, such as certain scientific simulations or financial modeling. However, for a broader range of tasks, the Intel chip falls behind. The 44.8% deficit in Cinebench R23 multi-core is a significant strike against it for rendering or video encoding, and the 76.2% single-core deficit is a major issue for everyday responsiveness and legacy application performance.

For a desktop user building a new system, the Ryzen 5 7400F is the clear pick. For a laptop buyer, the Core Ultra 7 155H is the only option, as it is a mobile part with integrated graphics, while the Ryzen has no integrated graphics. The choice is therefore largely predetermined by form factor, but within the benchmark data, the AMD part is the superior performer in most scenarios.

Where Each One Wins

The AMD Ryzen 5 7400F wins in all four Cinebench single-core tests, all three PassMark single-thread tests, and the majority of multi-threaded and data-processing tests. Its wins in Cinebench R20 multi-core (4.4%), Cinebench R23 multi-core (44.8%), PassMark multi-thread (3.1%), data compression (4.6%), data encryption (2.2%), extended instructions (32.2%), find prime numbers (69%), and random string sorting (9.7%) establish it as the superior chip for general productivity, code compilation, and typical desktop multitasking. The Ryzen also wins PassMark single-thread by 6.4%, making it better for single-threaded legacy software.

The Intel Core Ultra 7 155H wins in Cinebench R15 multi-core (10.5%), PassMark floating point math (28.1%), PassMark integer math (14%), and PassMark physics (3.9%). These are the only areas where Intel holds an advantage. The floating point and integer math wins are noteworthy for their size, but they represent a narrow slice of the benchmark suite. The Cinebench R15 multi-core win is the only Cinebench test Intel takes, and it is in the oldest version of the benchmark, suggesting that its advantage may not carry over to more modern workloads. The physics win is marginal at 3.9%, within a range that could be considered noise.
