AMD Ryzen 9 7940HX vs AMD Ryzen AI 9 365 Comparison

Head-to-Head Benchmarks

The benchmark data presents a clear split between these two mobile processors. The AMD Ryzen 9 7940HX dominates the multi-threaded and compute-heavy workloads, while the AMD Ryzen AI 9 365 takes a single win in single-core performance.

The most decisive victory for the Ryzen 9 7940HX comes in Cinebench R23 multicore, where it scores 29400 against the Ryzen AI 9 365's 18698. That is a 57.2% advantage. This gap is consistent across the Passmark suite. In integer math, the 7940HX posts 202883 versus 101831, a 99.2% lead. Floating point math shows a 93.3% edge, with scores of 121383 and 62802 respectively.

The encryption test delivers one of the largest deltas. The 7940HX scores 41974 in data encryption, which is 129.4% higher than the Ryzen AI 9 365's 18297. Extended instructions follow a similar pattern: 51029 versus 25113, a 103.2% difference. Prime number finding is another standout, with the 7940HX at 273 and the Ryzen AI 9 365 at 117, a 133.3% gap. Random string sorting shows a 107.3% lead for the 7940HX, scoring 81775 against 39447.

Data compression is the single largest percentage win recorded in the head-to-head. The 7940HX scores 693741, which is 95.7% ahead of the Ryzen AI 9 365's 354510. The Passmark multithread score continues the trend: 53204 for the 7940HX versus 29467, an 80.6% margin. Physics performance also favors the 7940HX, with 2297 against 1704, a 34.8% advantage.

The Ryzen AI 9 365's only head-to-head victory is in Cinebench R23 singlecore. It scores 1992, beating the 7940HX's 1807 by 9.3%. Interestingly, the Passmark single-thread test tells a slightly different story. There, the 7940HX edges ahead with 3942 versus 3841, a modest 2.6% lead. The two are nearly identical in that specific metric, but the Cinebench result gives the Ryzen AI 9 365 a clear single-core win.

Architecture Differences

The two CPUs come from different generations and use different designs. The Ryzen 9 7940HX belongs to the 7000 series and uses the Zen 4 architecture with the Dragon Range codename. It is built on TSMC's 5 nm process node. The Ryzen AI 9 365 is part of the Ryzen AI 300 series, uses the Zen 5 architecture (with a hybrid Zen 5 / Zen 5c configuration), and carries the Strix Point codename. Its process node is 4 nm from the same foundry.

Core counts differ substantially. The 7940HX has 16 cores and 32 threads, while the Ryzen AI 9 365 has 10 cores and 20 threads. The 7940HX has a base clock of 2.40 GHz and a boost clock of 5.20 GHz. The Ryzen AI 9 365 starts at 2.00 GHz and boosts to 5.00 GHz. The Ryzen 9 part also has a higher TDP at 55 watts, with the Ryzen AI 9 365 rated for 28 watts.

Cache hierarchies are built differently. The 7940HX allocates 64 KB of L1 cache per core and 1 MB of L2 per core, with a large 64 MB L3 cache. The Ryzen AI 9 365 has 80 KB of L1 per core, 1 MB of L2 per core, but only 16 MB of L3 cache. The die sizes reflect the different designs: the 7940HX uses a multi-chip layout with two 71 mm² dies, while the Ryzen AI 9 365 uses a single monolithic 233 mm² die. Transistor counts are listed only for the 7940HX at 13,140 million.

Memory support also diverges. The 7940HX supports DDR5 with dual-channel memory and a bandwidth of 83.2 GB/s. The Ryzen AI 9 365 supports DDR5 and LPDDR5X, also dual-channel, with a higher rated bandwidth of 89.6 GB/s. PCIe capability differs as well: the 7940HX offers Gen 5 with 28 lanes (CPU only), while the Ryzen AI 9 365 provides Gen 4 with 16 lanes. The integrated graphics differ, with the 7940HX using the Radeon 610M and the Ryzen AI 9 365 using the Radeon 880M. The 7940HX uses AMD Socket FL1, while the Ryzen AI 9 365 uses AMD Socket FP8. The 7940HX has an unlocked multiplier; the Ryzen AI 9 365 does not.

Where Each One Wins

The Ryzen 9 7940HX is the clear choice for heavy parallel workloads. Its 16 cores and 32 threads deliver massive leads in every multi-threaded Passmark test. The data shows it is particularly strong in integer math, floating point math, encryption, and data compression. For users running applications that scale across many cores, the benchmark results indicate a consistent and large advantage.

The 7940HX also wins in Passmark physics and multithread tests, reinforcing its position for CPU-intensive tasks such as rendering, simulation, and video encoding. The extended instructions score of 51029 versus 25113 shows that workloads using advanced instruction sets also favor the older part by a wide margin.

The Ryzen AI 9 365 wins only in Cinebench R23 singlecore. The 9.3% lead in that test suggests that its Zen 5 architecture delivers better per-core performance in at least one common benchmark. Its higher memory bandwidth of 89.6 GB/s compared to 83.2 GB/s may benefit memory-sensitive tasks, though the benchmark data does not directly show this. The integrated Radeon 880M is a newer graphics solution than the 610M, which may matter for light gaming or media workloads, but the recorded CPU benchmarks do not cover iGPU performance.

In Passmark single-thread, the two are close, with the 7940HX holding a small 2.6% lead. This indicates that for lightly threaded tasks, the difference is small enough to be within measurement noise. The Ryzen AI 9 365's 28-watt TDP also suggests it is designed for efficiency, but the data does not include power measurements.

The Verdict

The data points to two different use cases. The AMD Ryzen 9 7940HX is the stronger processor for multi-core performance. It wins 12 of the 13 recorded head-to-head benchmarks, with margins ranging from 2.6% to 133.3%. Its average benchmark score of 69875 places it in the 94th percentile of all CPUs. Its nearest rivals, such as the AMD Ryzen 7 9700F and Intel Core i7-14700KF, sit within 0.4% of its average score, confirming that it competes at the top of the desktop-class mobile range.

The AMD Ryzen AI 9 365 has an average benchmark score of 40048, landing in the 87th percentile. Its nearest rivals include the AMD Ryzen 7 7700 and the Intel Core 5 221E, with deltas under 0.7%. The Cinebench R23 singlecore win shows that Zen 5 brings a real single-thread improvement, but it is not enough to offset the 7940HX's core count advantage.

For users prioritizing multi-threaded throughput, the 7940HX is the clear pick. Its 57.2% lead in Cinebench R23 multicore and 80.6% lead in Passmark multithread are decisive. For users who value single-core responsiveness or need a lower-power chip, the Ryzen AI 9 365 has merit, but the Passmark single-thread results show only a 2.6% difference in the other direction. The overall data favors the 7940HX for raw performance.
