Where Each One Wins

The head-to-head split is 11 wins to 0, so the performance analysis is one-sided. The 8745HX wins every recorded PassMark test, including multithread, integer math, floating point math, physics, encryption, compression, extended instructions, prime number search, random string sorting, and single-thread performance. Its average score of 60104 places it at the 92nd percentile, and its nearest rivals in the database are the Ryzen 9 7945HX at 60099 with a 0% delta, the Core i9-14900F at 60008 with 0.2%, the Ryzen 9 7945HX3D at 59641 with 0.8%, and the Xeon Gold 6338T at 60572 with -0.8%.

The AI 5 PRO 440 has no recorded benchmark wins. Its average score of 41208 places it at the 87th percentile, with nearest rivals including the Core Ultra 7 356H at 41215 and a 0% delta, the Core Ultra 7 366H at 41263 with -0.1%, the Ryzen 9 5900X at 41376 with -0.4%, and the Core Ultra X7 358H at 40967 with 0.6%.

For workloads represented by these PassMark tests, the 8745HX is the higher-scoring processor in every case. The AI 5 PRO 440 does not claim a single head-to-head win. Its distinguishing features are in the specification sheet: a TDP of 28, a 4 nm process, DDR5 and LPDDR5X memory support, ECC memory support, and 89.6 GB/s of memory bandwidth. The 8745HX, meanwhile, combines a TDP of 55, DDR5 support, no ECC, and 83.2 GB/s of memory bandwidth with the larger core count and L3 cache. The benchmark wins belong entirely to the 8745HX, while the AI 5 PRO 440 is defined by its lower-power, newer-node mobile platform features.
