AMD Ryzen 9 8945HX vs Intel Core 7 251E Comparison

AMD Ryzen 9 8945HX vs Intel Core 7 251E

The Verdict

The database record for the AMD Ryzen 9 8945HX shows a 95th percentile ranking among all CPUs, while the Intel Core 7 251E sits at the 50th percentile. The AMD part has a recorded average benchmark score of 76,212, whereas the Intel part has no benchmark scores listed at all. From the data available, the Ryzen 9 8945HX is a high-end mobile processor with demonstrated performance across multiple test suites, while the Core 7 251E appears as a desktop chip with specifications but no recorded measurements in this database. The AMD part is positioned for demanding mobile workloads, and its benchmark results place it within a tight cluster around the Intel Core Ultra 9 285HX, AMD EPYC Embedded 8224P, AMD Ryzen Threadripper PRO 9945WX, and AMD Ryzen 9 9950X3D. The Intel Core 7 251E, by contrast, has no comparative data to anchor its standing. Based strictly on the recorded figures, the Ryzen 9 8945HX is the only part here with validated performance data, and it belongs to the upper tier of the database. The Intel part cannot be assessed for performance from this record, so any selection between the two would favor the AMD processor for anyone requiring measured results.

Architecture Differences

The AMD Ryzen 9 8945HX belongs to the 8000 series and uses the Zen 4 architecture under the Dragon Range codename. It is built on a 5 nm process at TSMC, with a transistor count of 13,140 million spread across two dies, each measuring 71 mm². The Intel Core 7 251E uses the Bartlett Lake codename and is manufactured on a 10 nm process at Intel, with a single die size of 257 mm². The transistor count for the Intel part is not recorded. The AMD processor is a mobile segment chip with 16 cores and 32 threads, while the Intel processor is a desktop segment chip with 24 cores and 32 threads. The AMD part has its multiplier unlocked, meaning it can be overclocked, while the Intel part has a locked multiplier. The AMD chip uses an AMD Socket FL1, and the Intel chip uses Intel Socket 1700. The integrated graphics differ as well: the AMD part carries a Radeon 610M, and the Intel part carries UHD Graphics 770. Memory support also diverges, with the AMD part supporting DDR5 only and the Intel part supporting both DDR4 and DDR5. The AMD chip does not support ECC memory, while the Intel chip does. The AMD part provides PCIe Gen 5 with 28 lanes from the CPU, and the Intel part provides PCIe Gen 5 with 16 lanes from the CPU.

Where Each One Wins

The AMD Ryzen 9 8945HX wins in every category where measured data exists. Its benchmark suite includes Cinebench R15, R20, and R23 tests for both multi-core and single-core performance, plus PassMark tests covering data compression, data encryption, extended instructions, prime number finding, floating point math, integer math, multithread performance, physics, random string sorting, and single-thread performance. The Intel Core 7 251E has no benchmark entries in the database, so no direct wins can be attributed to it. The AMD part also wins on architecture process size, using a 5 nm node versus the Intel part’s 10 nm node, and it has a higher transistor count. The AMD part has a higher base clock at 2.50 GHz versus 2.10 GHz, though the Intel part has a higher boost clock at 5.60 GHz versus 5.40 GHz. The AMD part has a larger L3 cache at 64 MB versus 36 MB shared on the Intel part. The AMD part also has more PCIe lanes at 28 versus 16. The Intel part counters with a higher memory bandwidth at 89.6 GB/s versus 83.2 GB/s, a larger die size, and support for both DDR4 and DDR5, plus ECC memory support. The Intel part has a lower per-core L1 cache size at 80 KB versus 64 KB per core, but that comparison is per core, and the core counts differ. The Intel part also has a higher TDP at 65 watts versus 55 watts. The AMD part holds an advantage in raw performance metrics, as every recorded score belongs to it.
