AMD Ryzen 9 PRO 8945HS vs AMD Ryzen AI 5 PRO 440 Comparison

The AMD Ryzen 9 PRO 8945HS and the AMD Ryzen AI 5 PRO 440 are both mobile processors from AMD, but they occupy different positions in the product stack. The database records a decisive result: the Ryzen 9 PRO 8945HS wins all 11 head-to-head benchmark comparisons, while the Ryzen AI 5 PRO 440 does not win a single test. This analysis covers the verdict, the use-case split, the architectural differences, and the benchmark data.

The Verdict

The Ryzen 9 PRO 8945HS is the clear performance pick. It wins every head-to-head test in the database, 11 out of 11. Its average benchmark score is 41963, compared to 41208 for the Ryzen AI 5 PRO 440. The 8945HS sits at the 88th percentile of all CPUs, while the 440 sits at the 87th. The 8945HS also has a higher core count (8 vs 6), more threads (16 vs 12), a higher base clock (4.00 GHz vs 2.00 GHz), and a higher boost clock (5.20 GHz vs 4.80 GHz). Its nearest rivals in the database include the Intel Core i7-14700T, which scores 41914 and is 0.1% behind, and the AMD Ryzen 5 7400, which scores 42055 and is 0.2% ahead. The 440's nearest rivals include the Intel Core Ultra 7 356H, which scores 41215 and is exactly tied, and the Intel Core Ultra 7 366H, which scores 41263 and is 0.1% ahead.

The Ryzen AI 5 PRO 440 is the efficiency pick. Its TDP is 28W, against 45W for the 8945HS. It also uses the newer Zen 5 architecture and supports LPDDR5X memory in addition to DDR5. However, the data shows that these advantages do not translate into any benchmark win. For any workload where performance is the primary criterion, the 8945HS is the choice. For a design that must fit a 28W power envelope, the 440 is the only option of the two, but it will be slower in every measured category. The 8945HS also records Cinebench R23 scores of 25165 in multicore and 3552 in single-core, along with R20 scores of 10569 and 1491, and R15 scores of 2536 and 357. These Cinebench results are not available for the 440 in the database.

Where Each One Wins

The head-to-head data is one-sided. The Ryzen 9 PRO 8945HS wins all 11 comparisons, and the Ryzen AI 5 PRO 440 wins none. The 8945HS leads in data compression (368884 vs 256420), data encryption (21820 vs 12418), extended instructions (27714 vs 18456), find prime numbers (91 vs 77), floating point math (63490 vs 42934), integer math (103390 vs 65991), multithread (30378 vs 21054), physics (1430 vs 1119), random string sorting (44668 vs 27252), and single thread (3920 vs 3785). The 440's only advantages are architectural: it uses the newer Zen 5 architecture, has a lower TDP of 28W, and supports LPDDR5X memory in addition to DDR5. But in the recorded benchmark data, none of those advantages translate into a win.

The use-case split is therefore simple. For any performance-sensitive task, whether it is data compression, encryption, integer or floating point math, or multithreaded rendering, the 8945HS is the pick. The 440 is the pick only when the 28W TDP is a hard requirement, and even then the performance gap is substantial. The 8945HS also records strong Cinebench scores: 25165 in R23 multicore and 3552 in R23 single-core, along with 10569 in R20 multicore and 1491 in R20 single-core, and 2536 in R15 multicore and 357 in R15 single-core. These scores are not available for the 440 in the database, so no direct comparison is possible, but they further illustrate the 8945HS's performance profile.
