AMD Ryzen 5 240 vs AMD Ryzen 7 7745HX Comparison

The AMD Ryzen 7 7745HX is the unequivocal performance leader in this comparison, winning every single head-to-head benchmark recorded in the database. The AMD Ryzen 5 240, while a newer part, cannot match the raw throughput of the 8-core Dragon Range chip. The data shows a consistent pattern: the Ryzen 7 7745HX delivers roughly 30% more multi-threaded performance across a wide range of tests, with smaller but still clear advantages in single-threaded workloads. There is no benchmark category where the Ryzen 5 240 emerges victorious.

Where Each One Wins

The benchmark results are decisive, with the AMD Ryzen 7 7745HX winning all 15 recorded head-to-head tests. There are no wins for the AMD Ryzen 5 240 in any measured category. For workloads that scale with core count and thread count, the Ryzen 7 7745HX is the superior choice. Its advantage is largest in processor-intensive tasks like prime number generation, where it leads by 55.1%, and physics calculations, where it leads by 37.5%.

The Ryzen 5 240 does not present a competitive case in any recorded benchmark. Its closest margin of defeat comes in single-threaded tests, where the Ryzen 7 7745HX leads by 5.8% in Cinebench R23 single-core and by 6.9% in Passmark single-thread tests. Even in lighter tasks like random string sorting, the Ryzen 7 7745HX maintains a 27.2% lead. For users whose primary concern is multi-threaded performance, the Ryzen 7 7745HX is the only rational selection based on this data.

Architecture Differences

The two processors share the same Zen 4 architecture but are built on different process nodes and packaged for different sockets. The AMD Ryzen 5 240 uses the Hawk Point codename and is fabricated on a 4 nm process by TSMC, with a die size of 178 mm² and 25,000 million transistors. It fits into the AMD Socket FP8. The AMD Ryzen 7 7745HX uses the Dragon Range codename and is built on a 5 nm process, with a smaller die size of 71 mm² and 6,570 million transistors. It uses the AMD Socket FL1.

Core and cache configurations differ significantly. The Ryzen 5 240 provides 6 cores and 12 threads, with a base clock of 4.30 GHz and a boost clock of 5.00 GHz. Its cache layout includes 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The Ryzen 7 7745HX offers 8 cores and 16 threads, with a lower base clock of 3.60 GHz but a higher boost clock of 5.10 GHz. Its L3 cache is doubled to 32 MB shared, while L1 and L2 per-core caches match at 64 KB and 1 MB respectively.

Memory support is DDR5 for both, with dual-channel buses. The Ryzen 5 240 has a higher memory bandwidth rating of 89.6 GB/s compared to 83.2 GB/s for the Ryzen 7 7745HX. The Ryzen 7 7745HX supports ECC memory, while the Ryzen 5 240 does not. PCIe connectivity also differs: the Ryzen 5 240 provides Gen 4 with 20 lanes, while the Ryzen 7 7745HX provides Gen 5 with 28 lanes. Integrated graphics are distinct, with the Ryzen 5 240 featuring the Radeon 760M and the Ryzen 7 7745HX featuring the Radeon 610M. The Ryzen 7 7745HX has an unlocked multiplier, while the Ryzen 5 240 does not. The Ryzen 7 7745HX has a higher TDP of 55 watts compared to 45 watts for the Ryzen 5 240.

The Verdict

Based strictly on the recorded data, the AMD Ryzen 7 7745HX is the superior processor for any workload that benefits from additional cores and threads. Its 8-core configuration with 16 threads consistently outperforms the 6-core, 12-thread Ryzen 5 240 by approximately 30% in multi-threaded tests. The largest single advantage is in prime number finding, where the Ryzen 7 7745HX scores 156 versus 70 for the Ryzen 5 240, a 55.1% lead. For physics simulations, the Ryzen 7 7745HX leads by 37.5%, scoring 1697 versus 1060.

For single-threaded performance, the Ryzen 7 7745HX also holds the edge, albeit by a smaller margin. In Cinebench R23 single-core, the Ryzen 7 7745HX scores 1850 against 1742 for the Ryzen 5 240, a 5.8% lead. The Passmark single-thread test shows a 6.9% lead for the Ryzen 7 7745HX, with scores of 3947 versus 3675. The Ryzen 5 240 does have a higher base clock (4.30 GHz versus 3.60 GHz) and higher memory bandwidth (89.6 GB/s versus 83.2 GB/s), but these advantages do not translate into benchmark victories.

The Ryzen 5 240 is a newer release, with a 2025 launch date compared to 2023 for the Ryzen 7 7745HX, and it uses a more advanced 4 nm process node. However, the performance data does not reflect any benefit from these factors. Users seeking maximum performance should select the AMD Ryzen 7 7745HX. The data provides no reason to choose the Ryzen 5 240 for performance-sensitive applications.
