AMD Ryzen 7 PRO 8845HS vs AMD Ryzen 9 7940H Comparison

Head-to-Head Benchmarks

The benchmark data shows a clear overall winner in raw performance: the AMD Ryzen 9 7940H takes 15 of the 17 recorded head-to-head comparisons, with the AMD Ryzen 7 PRO 8845HS claiming just 2 wins. However, the margin of victory matters as much as the tally, and the two processors are far closer than the win count suggests.

In the Cinebench suite, the Ryzen 9 7940H leads consistently but narrowly. In Cinebench R15 multicore, it scores 2490 against 2476 for the Ryzen 7 PRO 8845HS, a delta of just 0.6%. The single-core R15 result is equally tight: 351 versus 349, again 0.6%. Moving to Cinebench R20, the multicore gap remains at 0.6% (10375 vs 10317), while single-core narrows to 0.5% (1464 vs 1456). The R23 results follow the same pattern: multicore 24703 vs 24565 for 0.6%, and single-core 3487 vs 3468 for 0.5%. These are small but consistent advantages, indicating the Ryzen 9 7940H holds a slight clock-for-clock edge across rendering workloads.

The PassMark suite tells a more varied story. The Ryzen 9 7940H's largest wins come in extended instructions (26804 vs 25434, a 5.4% advantage), floating point math (62057 vs 58965, 5.2%), single-thread tests (3952 vs 3762, 5.1%), and integer math (101977 vs 97625, 4.5%). Data encryption also favors the Ryzen 9 7940H by 3% (21096 vs 20487), while data compression shows a 2.4% edge (352077 vs 343952). The multithread score is closer at 1.7% (29063 vs 28572), and random string sorting is nearly a tie at 0.5% (42093 vs 41867).

The Ryzen 7 PRO 8845HS fights back in two specific tests. It wins passmark find prime numbers with 87 versus 81, a 6.9% advantage for the Ryzen 7 PRO. It also takes passmark physics with 1389 versus 1300, a 6.4% lead. These wins hint at different optimization points, but they are isolated victories in workloads that do not translate into overall benchmark supremacy.

Looking at average scores, the Ryzen 9 7940H records an average benchmark score of 40431, placing it in the 87th percentile of all CPUs. The Ryzen 7 PRO 8845HS averages 39325, sitting in the 86th percentile. The nearest rivals for the Ryzen 9 7940H include the Intel Xeon 6507P at 40426 (0% delta), the Intel Core Ultra X7 368H at 40518 (-0.2%), the Intel Xeon 6369P at 40327 (0.3%), and the Intel Core i9-13905H at 40313 (0.3%). For the Ryzen 7 PRO 8845HS, the closest comparisons are the AMD EPYC 4245P at 39215 (0.3%), the AMD Ryzen AI 7 450 at 39485 (-0.4%), the AMD Ryzen 7 PRO 8840HS at 39603 (-0.7%), and the Intel Core i7-13700F at 39009 (0.8%). Both chips are clearly competitive in their respective brackets, but the Ryzen 9 7940H edges ahead in overall standing.

Architecture Differences

Both processors share a common foundation: 8 cores, 16 threads, Zen 4 architecture, a 4 nm process node from TSMC, 25,000 million transistors, and a die size of 178 mm². The cache hierarchy is identical as well: 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. Memory support is DDR5 dual-channel with 89.6 GB/s bandwidth, and both support ECC memory. Each integrates a Radeon 780M graphics unit and offers PCIe Gen 4 with 20 lanes (CPU only). Neither has an unlocked multiplier.

The key architectural divergence lies in the codename and generation. The Ryzen 9 7940H is built on the Phoenix design, part of the 7000 series and the Ryzen 9 generation. The Ryzen 7 PRO 8845HS uses the Hawk Point design, part of the 8000 series and the Ryzen 7 generation. Both are Zen 4 under the hood, but Hawk Point is a newer revision. The sockets differ: the Ryzen 9 7940H uses AMD Socket FP8, while the Ryzen 7 PRO 8845HS uses AMD Socket FP7. This means the physical platform requirements are not interchangeable.

Clock speeds separate the two. The Ryzen 9 7940H has a base clock of 4.00 GHz and a boost clock of 5.20 GHz. The Ryzen 7 PRO 8845HS starts lower at 3.80 GHz base and boosts to 5.10 GHz. That 0.20 GHz base clock and 0.10 GHz boost clock advantage for the Ryzen 9 7940H explains the consistent single-core and multicore wins in Cinebench. The TDP ratings flip the expected relationship: the Ryzen 9 7940H is rated at 35 W, while the Ryzen 7 PRO 8845HS is rated at 45 W. Despite the higher TDP on the Ryzen 7 PRO, it still trails in most benchmarks, suggesting the Ryzen 9 7940H achieves better performance per watt in these recorded tests.

The part numbers reflect the different platforms. The Ryzen 9 7940H lists 100-000000954 (FP7r2), 100-000000963 (FP7), and 100-000001128 (FP8). The Ryzen 7 PRO 8845HS lists 100-000001316 (FP7r2) and 100-000001387 (FP7). The release date for the Ryzen 7 PRO 8845HS is recorded as April 15, 2024, while no release date is listed for the Ryzen 9 7940H.

The Verdict

The data points to the AMD Ryzen 9 7940H as the higher-performing part in most workloads. It wins 15 of 17 head-to-head benchmarks, including every Cinebench test and most PassMark tests. The largest margins are in extended instructions (5.4%), floating point math (5.2%), single-thread (5.1%), and integer math (4.5%). Its average benchmark score of 40431 places it at the 87th percentile, above the Ryzen 7 PRO 8845HS's 39325 and 86th percentile. The Ryzen 9 7940H also achieves this with a lower TDP of 35 W versus 45 W, which is notable for mobile designs where thermal headroom matters.

The AMD Ryzen 7 PRO 8845HS is not without merit. It wins in passmark find prime numbers (87 vs 81) and passmark physics (1389 vs 1300), with the physics win being particularly substantial at 6.4%. It also has a recorded release date of April 15, 2024, making it a newer entry to the market. The Ryzen 7 PRO designation suggests a focus on professional and business-oriented features, though the benchmark data does not show a consistent performance advantage.

For users prioritizing raw compute performance across rendering, encryption, compression, and math workloads, the Ryzen 9 7940H is the clear choice from the recorded data. For users who value the physics workload performance or the prime number finding capability, the Ryzen 7 PRO 8845HS offers specific strengths. The performance gap in most tests is small, often under 1%, but the Ryzen 9 7940H's consistency and higher percentile ranking make it the stronger overall option.

Where Each One Wins

The AMD Ryzen 9 7940H dominates in rendering and content creation workloads. Every Cinebench test, from R15 to R23, in both single-core and multicore configurations, goes to the Ryzen 9 7940H. The margins are tight, ranging from 0.5% to 0.6%, but they are uniform. This suggests that for sustained CPU rendering tasks, the Ryzen 9 7940H provides a slight but reliable edge.

In data processing tasks, the Ryzen 9 7940H also leads. Data compression (2.4% advantage), data encryption (3%), extended instructions (5.4%), floating point math (5.2%), and integer math (4.5%) all favor the Ryzen 9 7940H. The multithread score (1.7% advantage) and random string sorting (0.5%) round out a comprehensive win in these categories. The single-thread score of 3952 versus 3762, a 5.1% lead, is one of the larger margins and indicates better per-core performance for lightly threaded applications.

The AMD Ryzen 7 PRO 8845HS wins in two specific areas. The passmark physics test shows a 6.4% advantage (1389 vs 1300), which may indicate better performance in physics simulation workloads. The passmark find prime numbers test shows a 6.9% lead (87 vs 81), suggesting an edge in prime number calculations. These are narrow, specialized wins that do not offset the broader trend.

For users choosing between the two, the decision hinges on workload priorities. The Ryzen 9 7940H is the better all-rounder for compute-heavy tasks, with a higher average score, higher percentile, and wins in nearly every category. The Ryzen 7 PRO 8845HS is the pick for physics simulations and prime number workloads, and it carries a newer release date. The socket difference (FP8 vs FP7) means platform compatibility will likely dictate the practical choice, but on pure benchmark performance, the Ryzen 9 7940H leads.
