The Ryzen 9 8940HX dominates nearly every multi-threaded workload, while the Ryzen AI 5 440G takes a narrow lead in single-thread tests. The recorded measurements show the 8940HX winning 9 of 11 head-to-head comparisons, with the 440G claiming 2 wins. The average benchmark score for the 8940HX is 81103, placing it at the 95th percentile of all CPUs, while the 440G averages 46187, sitting at the 89th percentile.

Head-to-Head Benchmarks

The Ryzen 9 8940HX delivers its largest margin in data encryption, scoring 39318 against the 440G's 13585, a delta of 189.4%. That result indicates a substantial advantage in cryptographic workloads, likely driven by the core count difference and higher sustained throughput. The find prime numbers test shows a similar pattern, with the 8940HX scoring 251 versus 90, a 178.9% lead. Integer math follows at 165.6% ahead, with scores of 189221 and 71251 respectively.

Floating point math favors the 8940HX by 149.2%, recording 113921 against 45711. Random string sorting shows a 142.3% advantage for the 8940HX, with scores of 75381 and 31106. Extended instructions deliver a 131.5% gap, 47802 versus 20648. Data compression is 122.4% higher on the 8940HX, at 650984 compared to 292735. The multithread benchmark shows a 111.7% lead, with 49731 against 23487. Physics simulation completes the sweep of multi-thread wins, with the 8940HX at 2104 and the 440G at 1329, a 58.3% difference.

The only area where the 440G wins is single-thread performance. The passmark single thread test records 4060 for the 440G against 3874 for the 8940HX, a 4.6% advantage. That margin repeats across both the single_thread and singlethread entries, confirming consistency in the measurement. The 8940HX has no single-thread win in the recorded data.

The scale of the multi-thread gaps is notable. The 8940HX doubles or nearly doubles the 440G in seven of the nine head-to-head tests it wins. The smallest multi-thread margin, physics at 58.3%, still represents a decisive lead. These results align with the core and thread counts, where the 8940HX uses 16 cores and 32 threads against 6 cores and 12 threads on the 440G.

Where Each One Wins

The Ryzen 9 8940HX is the choice for heavily parallel workloads. Data encryption, integer math, floating point math, and data compression all show the 8940HX ahead by more than 100%. The multithread benchmark confirms this, with the 8940HX scoring more than double the 440G. The 8940HX also wins in find prime numbers, extended instructions, random string sorting, and physics, making it the stronger option for any task that scales across cores. The data shows the 8940HX at the 95th percentile overall, and its nearest rivals include Intel Core i9-14900KS and Intel Xeon w5-3535X, both with average scores within 0.5% of its own.

The Ryzen AI 5 440G wins exclusively in single-thread performance. Its 4060 score in the passmark single thread test is 4.6% higher than the 8940HX's 3874. That advantage is modest but consistent, and it positions the 440G as the better option for lightly threaded applications where per-core speed matters more than total throughput. The 440G sits at the 89th percentile, with nearest rivals including Intel Core i9-13900HX and AMD Ryzen AI 9 HX 375, each within 0.3% to 0.5% of its average score.

For mixed workloads, the 8940HX's overall average score of 81103 versus 46187 for the 440G indicates a 75.6% advantage in aggregate performance. The 440G does not approach the 8940HX in any multi-thread metric, so its single-thread edge is the only scenario where it leads.

The Verdict

The benchmark data supports a straightforward conclusion: the Ryzen 9 8940HX is the stronger processor for multi-threaded workloads, and the Ryzen AI 5 440G is the stronger processor for single-thread performance. The 8940HX wins 9 of 11 head-to-head comparisons, with margins ranging from 58.3% in physics to 189.4% in data encryption. Its average benchmark score of 81103 places it among high-end desktop and workstation parts, near the Intel Core i9-14900KS and Intel Xeon w5-3535X. The 440G, with an average of 46187, aligns with parts like the Intel Core i9-13900HX and AMD Ryzen AI 9 HX 375.

The 440G's single-thread win by 4.6% is real but narrow. It does not offset the 8940HX's massive multi-thread advantage in most workloads. The 8940HX's 16 cores and 32 threads, combined with 64 MB of L3 cache, deliver results that the 6-core, 12-thread 440G with 8 MB of L3 cache cannot approach in parallel tasks. The 440G's higher memory bandwidth of 89.6 GB/s and newer 4 nm process node do not translate into multi-thread wins in the recorded data.

For users prioritizing throughput in compression, encryption, math, or physics, the 8940HX is the clear pick. For users running lightly threaded applications where single-core speed is the bottleneck, the 440G offers a modest edge. The overall performance ranking, with the 8940HX at the 95th percentile and the 440G at the 89th, captures that hierarchy. The data does not show any scenario where the 440G approaches the 8940HX in aggregate performance.
