AMD Ryzen 9 7940HX vs AMD Ryzen AI 7 PRO 450 Comparison

Head-to-Head Benchmarks

The recorded data presents a clear, lopsided comparison across the shared benchmark suite. The AMD Ryzen 9 7940HX wins 10 of the 13 head-to-head tests, while the AMD Ryzen AI 7 PRO 450 secures 3 wins. The margins, however, are not uniform.

The largest single victory for the Ryzen 9 7940HX comes in the `passmark_find_prime_numbers` test, where it scores 273 against 84 for the Ryzen AI 7 PRO 450, a delta of 225%. This is an extreme outlier and indicates a fundamental throughput advantage in integer-heavy, latency-sensitive workloads. Following that, the Ryzen 9 7940HX leads `passmark_data_encryption` by 181.2% (41974 vs 14925) and `passmark_random_string_sorting` by 152.8% (81775 vs 32344). In each case, the higher core and thread counts of the Ryzen 9 7940HX (16 cores, 32 threads) versus the Ryzen AI 7 PRO 450 (8 cores, 16 threads) directly translate into proportional performance gains.

The extended instructions test shows a 145.6% advantage for the Ryzen 9 7940HX (51029 vs 20778). Integer math follows at 135.3% (202883 vs 86227), and data compression at 135.7% (693741 vs 294298). These are all heavily parallel workloads where the 16-core part can leverage its full resource pool. The `passmark_multithread` score confirms the pattern: 53204 for the Ryzen 9 7940HX versus 24779 for the Ryzen AI 7 PRO 450, a 114.7% difference. Floating-point math also favors the larger chip, with a 129.1% delta (121383 vs 52971).

The Cinebench R23 multicore result narrows the gap somewhat compared to the PassMark suite but still shows a decisive win for the Ryzen 9 7940HX: 29400 versus 16054, a 83.1% advantage. In `passmark_physics`, the Ryzen 9 7940HX leads by 71.8% (2297 vs 1337), which is the smallest multicore margin outside of Cinebench R23.

The Ryzen AI 7 PRO 450 wins the single-threaded contests, but only by thin margins. In Cinebench R23 single-core, it scores 2010 versus 1807 for the Ryzen 9 7940HX, a 10.1% advantage. The PassMark single-thread test shows a negligible 0.3% lead for the Ryzen AI 7 PRO 450 (3955 vs 3942). These results indicate that the Zen 5 architecture in the Ryzen AI 7 PRO 450 delivers slightly better per-core efficiency, but the Zen 4 cores in the Ryzen 9 7940HX are not far behind, and the latter's massive core count overwhelms in any parallel workload.

Where Each One Wins

The Ryzen 9 7940HX is the clear winner for any multi-threaded, compute-intensive task. The data confirms this across the board: rendering (Cinebench R23 multicore), data compression, encryption, extended instruction sets, prime number calculations, floating-point math, integer math, random string sorting, and general multithreaded processing all fall to the 16-core part. Its `passmark_multithread` score of 53204 is more than double that of the Ryzen AI 7 PRO 450. For users running parallel compilation, video encoding, scientific simulations, or heavy data processing, the benchmark results consistently favor the Ryzen 9 7940HX by margins ranging from 71.8% to 225%.

The Ryzen AI 7 PRO 450 wins exclusively in single-threaded performance. Its Cinebench R23 single-core score of 2010 exceeds the Ryzen 9 7940HX's 1807 by 10.1%. The PassMark single-thread score also goes to the Ryzen AI 7 PRO 450, albeit by a razor-thin 0.3% (3955 vs 3942). This suggests that for lightly threaded applications, such as many legacy games or single-threaded productivity tools, the Ryzen AI 7 PRO 450 holds a measurable, though modest, edge. The `passmark_physics` result, which often reflects real-time game physics, shows a substantial win for the Ryzen 9 7940HX (2297 vs 1337), indicating that even in gaming-adjacent workloads, the core count advantage of the Ryzen 9 7940HX dominates.

The overall average benchmark scores place the Ryzen 9 7940HX at 69875, which ranks in the 94th percentile of all CPUs in the database. The Ryzen AI 7 PRO 450 averages 37093, ranking in the 85th percentile. The Ryzen 9 7940HX sits among rivals such as the AMD Ryzen 7 9700F (avg score 69996, delta -0.2%) and the Intel Core i7-14700KF (avg score 70163, delta -0.4%). The Ryzen AI 7 PRO 450 is positioned near the Intel Core i9-12900T (avg score 37112, delta -0.1%) and the AMD Ryzen 7 160 (avg score 37117, delta -0.1%). These relative positions underscore that the Ryzen 9 7940HX competes in a higher performance tier entirely.

The Ryzen 9 7940HX has a memory bandwidth of 83.2 GB/s, while the Ryzen AI 7 PRO 450 has a slightly higher 89.6 GB/s. ECC memory support is absent on the Ryzen 9 7940HX but present on the Ryzen AI 7 PRO 450.

The socket types are different: AMD Socket FL1 for the Ryzen 9 7940HX, and AMD Socket FP8 for the Ryzen AI 7 PRO 450. The integrated graphics units are not the same: the Ryzen 9 7940HX uses the Radeon 610M, while the Ryzen AI 7 PRO 450 uses the Radeon 860M. PCIe support also differs, with the Ryzen 9 7940HX offering Gen 5 with 28 lanes, while the Ryzen AI 7 PRO 450 offers Gen 4 with 16 lanes.

The die size is substantially different, with the Ryzen 9 7940HX using a 2x 71 mm² configuration versus a single 195 mm² die for the Ryzen AI 7 PRO 450. The Ryzen 9 7940HX has a transistor count of 13,140 million, while the Ryzen AI 7 PRO 450 transistor count is not recorded in the database.

Architecture Differences

The architectural split is significant. The Ryzen 9 7940HX is based on Zen 4 architecture, codenamed Dragon Range, and belongs to the 7000 series. It is manufactured on a 5 nm process by TSMC. Its cache hierarchy consists of 64 KB of L1 per core, 1 MB of L2 per core, and 64 MB of L3 cache.

The Ryzen AI 7 PRO 450 uses the Zen 5 architecture, codenamed Gorgon Point, and belongs to the Ryzen AI PRO 400 generation, which combines Zen 5 and Zen 5c cores. It is manufactured on a 4 nm process, also by TSMC. Its L1 cache is larger at 80 KB per core, but L2 remains at 1 MB per core. The L3 cache is much smaller at 8 MB, compared to the 64 MB on the Ryzen 9 7940HX.

These architectural differences explain the benchmark patterns. The Zen 5 cores in the Ryzen AI 7 PRO 450 deliver a higher single-core score (2010 in Cinebench R23) despite a lower boost clock (5.10 GHz versus 5.20 GHz) and a lower base clock (2.00 GHz versus 2.40 GHz). The smaller L3 cache on the Ryzen AI 7 PRO 450 (8 MB) contrasts sharply with the 64 MB on the Ryzen 9 7940HX, yet the latter's advantage in multithreaded tests stems primarily from having twice as many cores and threads.

The production status for both is active. The Ryzen 9 7940HX was released on 2024-01-16, while the Ryzen AI 7 PRO 450 has a release date of 2026-01-04. Both are mobile market segments, but the Ryzen 9 7940HX carries a 55W TDP versus 28W for the Ryzen AI 7 PRO 450, indicating the former targets higher-performance laptops while the latter is positioned for more power-efficient designs. The Ryzen AI 7 PRO 450 also supports ECC memory and a wider memory type range (DDR5 and LPDDR5X), which are features associated with professional and AI-oriented workloads.
