Where Each One Wins

The Intel Core 7 251TE wins in nearly every compute-heavy workload. Its 24-core, 32-thread configuration gives it a decisive edge in multicore rendering, as shown by the 42.1% lead in Cinebench R23 multicore and the 52.1% lead in single-core Cinebench R23. The Intel part also leads in floating point math, integer math, physics simulation, prime number finding, encryption, compression, multithreaded tasks, and random string sorting. For users who run heavily threaded workloads, such as video encoding, 3D rendering, or scientific computation, the Intel part is the stronger choice based on the recorded data.

The AMD Ryzen 7 PRO 8840HS wins in extended instructions, scoring 31.4% higher than the Intel part. This suggests an advantage in workloads that use specialized instruction sets, such as certain cryptography or signal processing tasks. The AMD part also wins in PassMark single-thread by a 3.5% margin. For users whose primary tasks rely on single-threaded performance or extended instruction execution, the AMD part offers a measurable advantage.

The AMD part also has a much lower TDP at 28 W versus 45 W for the Intel part. This indicates the AMD part draws less power, which is relevant for mobile or thermally constrained systems. The AMD part is a mobile processor, while the Intel part is a desktop processor, so the platform choice will influence which part is appropriate.

The Verdict

The data clearly favors the Intel Core 7 251TE for overall performance. It wins 12 of 15 head-to-head benchmarks, including the most demanding multicore and single-core tests. The Intel part has a 42.1% lead in Cinebench R23 multicore and a 52.1% lead in Cinebench R23 single-core, which are substantial margins. Its higher core count, larger cache, and higher boost clock all contribute to this result. The Intel part also has a higher average benchmark score of 41,650 versus 39,603 for the AMD part, and a higher percentile ranking at 88 versus 87.

The AMD Ryzen 7 PRO 8840HS is the better choice for specific workloads. Its 31.4% lead in extended instructions and 3.5% lead in PassMark single-thread indicate that certain instruction-heavy or lightly threaded tasks will run faster on the AMD part. The AMD part also operates at a lower TDP of 28 W, making it more suitable for power-sensitive mobile designs. Its smaller die size of 178 mm² versus 215 mm² may also be relevant for space-constrained builds.

For a desktop user who needs maximum compute throughput across a wide range of tasks, the Intel Core 7 251TE is the data-backed selection. For a mobile user who prioritizes power efficiency and runs workloads that benefit from extended instructions or single-thread performance, the AMD Ryzen 7 PRO 8840HS is the appropriate pick. The choice between the two should depend on the target platform and the specific workload mix, as the benchmark results show a clear split in strengths.
