AMD Ryzen 5 7400F vs AMD Ryzen 7 7745HX Comparison

Both processors belong to AMD’s 7000 series and share the Zen 4 architecture, yet they are engineered for entirely different environments. The AMD Ryzen 7 7745HX is a mobile part in the Dragon Range family, designed for high-performance laptops, while the AMD Ryzen 5 7400F is a desktop chip from the Raphael lineup. The benchmark data reveals a fascinating split: the 7745HX wins the majority of tests (11 out of 15), but the 7400F secures decisive victories in several critical workloads, including the newer Cinebench versions. This suggests a complex trade-off between raw core count and per-core efficiency that depends heavily on the specific application.

Where Each One Wins

The Ryzen 7 7745HX establishes its dominance in heavily threaded, compute-intensive tasks. It wins the Cinebench R15 multi-core test by a wide margin, scoring 2986 versus 2193, a 36.2% advantage. This pattern repeats across the Passmark suite, where the 7745HX takes the top spot in integer math, floating point math, data compression, data encryption, extended instructions, and multithreaded performance. The 8-core, 16-thread configuration provides a clear edge in workloads that scale with core count, making it the stronger choice for video rendering, scientific simulations, and complex data processing. The data suggests this mobile chip punches well above its weight class, delivering performance that rivals desktop processors despite its 55 W TDP.

Conversely, the Ryzen 5 7400F claims victory in Cinebench R23, both single-core and multi-core, where it outscores the 7745HX by 15.2% and 39.8% respectively. It also wins the Cinebench R15 single-core test and the Passmark find prime numbers benchmark. The 7400F’s higher boost clock of 4.70 GHz, compared to 5.10 GHz for the 7745HX, is not the whole story—the desktop chip appears to sustain higher performance under load, likely due to its 65 W TDP and more robust desktop thermal environment. This makes the 7400F the better option for lightly threaded applications, gaming scenarios that rely on single-core speed, and older software that does not utilize many cores.

Architecture Differences

Despite sharing the same Zen 4 microarchitecture, 5 nm process node, and TSMC as the foundry, the two chips diverge significantly in their physical design and platform integration. Both have the identical transistor count of 6,570 million and die size of 71 mm², but the 7745HX is built on the Dragon Range codename, while the 7400F uses Raphael. The 7745HX features 8 cores and 16 threads, whereas the 7400F has 6 cores and 12 threads. This core deficit is partially offset by the 7400F’s higher base clock of 3.70 GHz versus 3.60 GHz, and its boost clock advantage is not uniform—the 7745HX actually boosts higher to 5.10 GHz.

The cache hierarchy is identical in structure: 64 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3 cache. Memory support is also the same, with both supporting DDR5, dual-channel memory, and a memory bandwidth of 83.2 GB/s. Both support ECC memory and have an unlocked multiplier. The critical differences lie in the platform. The 7745HX uses the AMD Socket FL1, typical for mobile processors, and comes with integrated Radeon 610M graphics. The 7400F uses the desktop AMD Socket AM5 and has no integrated graphics, requiring a discrete GPU. PCIe lane counts also differ, with the 7745HX offering 28 lanes versus 24 for the 7400F, both Gen 5. The 7745HX was released in January 2023, while the 7400F arrived in January 2025, making the desktop part a much newer product.

Head-to-Head Benchmarks

The most striking result is the Cinebench R23 single-core test, where the 7400F achieves a score of 3072 compared to the 7745HX’s 1850, a 39.8% advantage. This is an enormous gap for processors from the same architecture and generation, indicating that the desktop chip’s power delivery and thermal headroom allow it to sustain much higher clock speeds on a single core. The multi-core R23 result also favors the 7400F, with a score of 21765 versus 18452.5, a 15.2% difference, despite having fewer cores. This suggests that the 7745HX’s 8 cores are not able to maintain their boost clocks under sustained multi-threaded load in a mobile chassis, likely due to thermal throttling.

However, the 7745HX fights back decisively in the Passmark suite. In integer math, it scores 105773 against the 7400F’s 74745, a 41.5% lead. Floating point math shows a similar story, with 64297 versus 45799, a 40.4% advantage. Data compression results are also lopsided, with the 7745HX at 383322 versus 289999, a 32.2% difference. Data encryption favors the 7745HX by 37.4%, and extended instructions by 33.2%. The multithreaded Passmark score gives the 7745HX a 27% edge, which is more consistent with its core count advantage. Interestingly, the single-threaded Passmark results show the 7745HX ahead by 7%, contradicting the Cinebench R23 single-core result, highlighting how different benchmark methodologies can produce conflicting outcomes.

FAQ

Q: Why does the Ryzen 5 7400F win Cinebench R23 multi-core despite having fewer cores?

A: The 7400F scores 21765 in Cinebench R23 multi-core versus 18452.5 for the 7745HX, a 15.2% advantage. The desktop platform’s 65 W TDP and superior cooling allow the 7400F to maintain higher sustained boost clocks across all 6 cores, while the mobile 7745HX likely throttles under load, preventing its 8 cores from reaching their full potential.

Q: Which processor is better for data compression and encryption workloads?

A: The Ryzen 7 7745HX dominates these tasks, scoring 383322 in data compression (32.2% higher) and 22967 in data encryption (37.4% higher) compared to the 7400F. The additional two cores and 16 threads provide a significant advantage in these parallelizable workloads.

Q: Is the Ryzen 5 7400F always faster in single-threaded tasks?

A: No, the results are mixed. The 7400F wins Cinebench R15 and R23 single-core tests by 4.7% and 39.8% respectively, but the 7745HX wins the Passmark single-thread test by 7%. The discrepancy likely stems from different workload characteristics and how each benchmark stresses the processor.

Q: Do both processors support the same memory and expansion features?

A: Both support DDR5, dual-channel memory, 83.2 GB/s bandwidth, and ECC memory. However, the 7745HX offers 28 PCIe Gen 5 lanes, while the 7400F has 24 lanes. The 7745HX also includes integrated Radeon 610M graphics, whereas the 7400F has no integrated GPU.

Q: How do these processors compare to their nearest rivals in overall average score?

A: The 7745HX has an average benchmark score of 33091, placing it alongside the Intel Core i7-13650HX and AMD Ryzen 7 8700G with a 0% delta, and slightly ahead of the AMD Ryzen 9 PRO 6950H by 0.3%. The 7400F averages 32750, with the Intel Core i5-14600T 0.1% lower and the Intel Core Ultra 7 155H 0.2% lower.

Q: Which processor has a higher boost clock?

A: The Ryzen 7 7745HX has a higher boost clock of 5.10 GHz, while the Ryzen 5 7400F boosts to 4.70 GHz. Despite this, the 7400F often performs better in single-threaded benchmarks, indicating that sustained clock speeds matter more than peak boost capability.

The Verdict

The data presents a clear choice for different use cases. The Ryzen 7 7745HX is the definitive winner for multi-threaded productivity and content creation. Its 41.5% lead in integer math, 40.4% lead in floating point math, and 27% lead in multithreaded Passmark scores make it the superior choice for video editing, 3D rendering, and scientific computing. The 36.2% advantage in Cinebench R15 multi-core further reinforces this. For users who spend their time in heavily parallel workloads, the 7745HX’s extra cores are invaluable, even in a mobile form factor.

The Ryzen 5 7400F, on the other hand, is the better pick for gaming and single-threaded applications. The 39.8% lead in Cinebench R23 single-core is a massive margin that will translate to higher frame rates in CPU-bound games. The 15.2% advantage in Cinebench R23 multi-core also suggests that for many real-world applications, the 7400F’s ability to sustain high clocks across all cores is more important than raw core count. The 7400F is also a desktop part, offering the upgradeability and thermal solutions typical of that platform. The choice is not about which is “better” overall, but which aligns with the user’s primary workload.
