AMD Ryzen 5 7400F vs Intel Core Ultra 7 366H Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear and consistent picture: the Intel Core Ultra 7 366H wins every single recorded benchmark comparison against the AMD Ryzen 5 7400F. Across 17 head-to-head tests, the Intel part takes all 17 wins, with the margin varying from a modest 8.8% to a dominant 55.8%.

The Cinebench suite shows a remarkably uniform gap. In Cinebench R15 multicore, the Intel chip scores 2870 against AMD's 2193, a 23.6% advantage. The single-core R15 test shows nearly the same margin: 405 versus 309, also 23.7% in Intel's favor. This pattern repeats in Cinebench R20, where multicore scores are 11960 against 9141 (23.6% gap), and single-core 1688 against 1290 (23.6%). Cinebench R23 continues the trend: Intel posts 28477 in multicore versus AMD's 21765, and 4020 in single-core versus 3072, both at a 23.6% delta. The consistency of this 23.6% figure across multiple Cinebench versions indicates a structural performance difference rather than workload-specific noise.

The PassMark suite reveals where the gap widens or narrows. The smallest Intel advantage appears in single-threaded workloads: PassMark single-thread scores are 4043 versus 3689, an 8.8% lead. Integer math is close as well, with Intel at 83695 against AMD's 74745, a 10.7% margin. Data compression shows an 11.4% gap (327455 versus 289999), and random string sorting is 11.9% apart (39814 versus 35096). These sub-12% deltas suggest that in lightly threaded integer tasks, the AMD part remains competitive.

The largest gaps emerge in floating-point and physics workloads. PassMark floating-point math shows Intel at 103615 versus AMD's 45799, a staggering 55.8% difference. Physics tests follow at 42.4% apart (2880 versus 1660). Prime number finding is 41.4% in Intel's favor (326 versus 191), and data encryption shows a 35.3% gap (25845 versus 16712). Extended instructions favor Intel by 19.2% (26901 versus 21747). PassMark multithread, a broad measure of parallel performance, gives Intel a 23.3% edge (33429 versus 25645).

The Verdict

The data supports a straightforward conclusion: the Intel Core Ultra 7 366H is the faster processor in every measured category. Its average benchmark score of 41263 places it at the 87th percentile of all CPUs in the database, while the AMD Ryzen 5 7400F averages 32750 and sits at the 83rd percentile. The overall average score delta is substantial, roughly 26% in Intel's favor.

For workloads that stress floating-point math, physics simulation, or encryption, the Intel chip is the clear choice. The 55.8% lead in floating-point math and 42.4% lead in physics are decisive. For single-threaded integer tasks, the Intel advantage narrows to under 9%, making the gap less pronounced but still present.

The AMD part does not win any benchmark category. However, its nearest rivals in the database include the Intel Core i5-14600T (average score 32707, just 0.1% behind) and the Intel Core Ultra 7 155H (32697, 0.2% behind). This places the Ryzen 5 7400F in a competitive position against other mid-range desktop and mobile parts, even if it trails the Core Ultra 7 366H specifically.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 5 7400F uses the Zen 4 architecture, codenamed Raphael, built on TSMC's 5 nm process. It is a desktop part with 6 cores and 12 threads, housed in AMD Socket AM5. The Intel Core Ultra 7 366H uses the Panther Lake architecture, built on Intel's 3 nm process, and is a mobile part with 16 cores and 16 threads in a BGA 2540 package.

The core counts differ sharply: 6 physical cores with simultaneous multithreading on AMD versus 16 physical cores without hyperthreading on Intel. This explains why Intel's multithreaded benchmarks show a 23.3% advantage despite having equal thread counts (16 threads on Intel versus 12 threads on AMD). Intel's higher core count directly translates into superior parallel throughput.

Cache hierarchies also diverge. AMD provides 64 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3. Intel provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Intel chip has more per-core cache at every level, but less shared L3 overall. The process node difference (5 nm versus 3 nm) gives Intel a manufacturing advantage in density and potentially in power efficiency per transistor.

Memory support differs as well. AMD supports DDR5 only, with a dual-channel bus and 83.2 GB/s of bandwidth. Intel supports both DDR5 and LPDDR5X, also dual-channel, with 115.2 GB/s of bandwidth. The 38% bandwidth advantage on Intel likely contributes to its strong performance in memory-sensitive workloads. AMD supports ECC memory; Intel does not. PCIe connectivity also differs: AMD offers 24 CPU lanes of Gen 5, while Intel offers 12 lanes. The AMD part has no integrated graphics, while the Intel chip includes Intel Xe3 Graphics.

Where Each One Wins

The Intel Core Ultra 7 366H wins every recorded benchmark, so the question is not which processor wins individual tests, but rather where the margins matter most. The Intel chip is strongest in floating-point math, where its 55.8% lead is the largest of any category. Physics simulation follows at 42.4%, and prime number finding at 41.4%. Data encryption shows a 35.3% edge. These workloads benefit from the combination of 16 physical cores, larger per-core caches, and higher memory bandwidth.

The AMD Ryzen 5 7400F, despite losing all comparisons, shows its most competitive results in specific niches. Single-thread performance is closest, with an 8.8% gap. Integer math is 10.7% behind, and data compression is 11.4% behind. Random string sorting is 11.9% off. These are all sub-12% margins, indicating that in lightly threaded integer workloads, the Zen 4 architecture keeps the AMD part within striking distance.

For multithreaded Cinebench workloads, the Intel advantage sits at a consistent 23.6%, reflecting the core count difference. The PassMark multithread score confirms this at 23.3%. Extended instructions show a 19.2% gap. The AMD chip's 6 cores and 12 threads simply cannot match the parallel throughput of Intel's 16 cores, even though both processors deliver 16 threads on the Intel side and 12 on the AMD side.
