AMD Ryzen 9 8940HX vs AMD Ryzen AI 9 PRO 465 Comparison

Head-to-Head Benchmarks

The benchmark comparison between the AMD Ryzen 9 8940HX and the AMD Ryzen AI 9 PRO 465 is dominated by the former, which wins 9 of the 11 recorded head-to-head tests. The most decisive victory comes in data encryption, where the Ryzen 9 8940HX scores 39,318 against 19,308, a 103.6% advantage. This is followed closely by the find prime numbers test, where the 8940HX posts 251 versus 126, a 99.2% lead. Extended instructions show an 80.8% gap (47,802 vs 26,441), and random string sorting shows an 84.5% gap (75,381 vs 40,860). These results indicate that the 8940HX is exceptionally strong in tasks that involve cryptographic work, prime number calculations, and complex instruction sets.

The multi-core performance gap is substantial but not as extreme as the encryption delta. In the passmark multithread test, the 8940HX scores 49,731, which is 58% higher than the 31,485 posted by the Ryzen AI 9 PRO 465. Integer math follows a similar pattern: 189,221 versus 107,173, a 76.6% advantage. Floating point math shows a 70.5% lead (113,921 vs 66,824). Data compression is 69% ahead (650,984 vs 385,174). These figures confirm that the 8940HX is the clear choice for heavily threaded workloads.

The physics test is one of the closer contests, with the 8940HX winning 2,104 to 1,747, a 20.4% edge. This is the smallest winning margin for the 8940HX across all tests. The single-threaded results are the only place where the Ryzen AI 9 PRO 465 takes the lead. In the passmark single_thread test, it scores 4,168 against 3,874, a 7.1% advantage. This is a consistent finding, as the identical score appears in the passmark singlethread test, confirming that the Zen 5 architecture in the Ryzen AI 9 PRO 465 delivers better per-core performance despite having fewer cores.

Where Each One Wins

The Ryzen 9 8940HX is the clear winner in all multithreaded and throughput-oriented workloads. With 16 cores and 32 threads, it delivers 58% higher multithread scores, 76.6% higher integer math scores, and 70.5% higher floating point math scores. The data compression advantage of 69% makes it the superior processor for file compression, archiving, and database workloads. The 103.6% encryption advantage is particularly notable, suggesting that the 8940HX is built for environments where data security and bulk encryption tasks are frequent. The 99.2% lead in find prime numbers indicates strength in mathematical computing and cryptographic algorithm testing.

The Ryzen AI 9 PRO 465 wins only in single-threaded performance, with a 7.1% advantage in both recorded single-thread tests. This means it is the better choice for lightly threaded applications, such as older games, single-threaded productivity tools, and tasks that rely on one fast core. The higher boost clock of 5.00 GHz, combined with the Zen 5 architecture, likely contributes to this result. However, the 8940HX is not far behind in this area, so the practical difference is modest. For users who prioritize responsiveness in everyday applications that do not scale across many cores, the Ryzen AI 9 PRO 465 offers a slight edge. For everything else, the 8940HX is measurably faster.

Architecture Differences

The two processors represent different architectural generations and design philosophies. The Ryzen 9 8940HX uses the Zen 4 architecture, codenamed Dragon Range, built on a 5 nm process at TSMC. It has 16 cores and 32 threads with a base clock of 2.40 GHz and a boost clock of 5.30 GHz. The Ryzen AI 9 PRO 465 uses the Zen 5 architecture, codenamed Gorgon Point, built on a 4 nm process at TSMC. It has 10 cores and 20 threads with a base clock of 2.00 GHz and a boost clock of 5.00 GHz. The newer 4 nm process node gives the Ryzen AI 9 PRO 465 a manufacturing advantage, but the 8940HX compensates with more cores and higher clock speeds.

The cache configurations differ substantially. The 8940HX has a 64 MB L3 cache, while the Ryzen AI 9 PRO 465 has a 16 MB L3 cache. Per-core L1 cache is 64 KB on the 8940HX versus 80 KB on the Ryzen AI 9 PRO 465. Both use 1 MB L2 cache per core. The larger L3 cache on the 8940HX helps with multi-threaded workloads that share data across cores, while the larger per-core L1 on the Ryzen AI 9 PRO 465 may contribute to its single-threaded advantage.

The memory and interface specifications also differ. The 8940HX supports DDR5 memory with a dual-channel bus and 83.2 GB/s bandwidth. The Ryzen AI 9 PRO 465 supports DDR5 and LPDDR5X memory with a dual-channel bus and 89.6 GB/s bandwidth. The latter has a higher theoretical memory bandwidth, which may help in memory-intensive tasks. The 8940HX uses PCIe Gen 5 with 28 lanes, while the Ryzen AI 9 PRO 465 uses PCIe Gen 4 with 16 lanes. The 8940HX offers more PCIe bandwidth for expansion devices. The integrated graphics also differ: the 8940HX features the Radeon 610M, while the Ryzen AI 9 PRO 465 features the Radeon 890M, which is a more capable integrated GPU.

Power characteristics are another key difference. The 8940HX has a TDP of 55 watts, while the Ryzen AI 9 PRO 465 has a TDP of 28 watts. This nearly 2x difference in power envelope explains the 8940HX's higher multi-threaded performance. The 8940HX also has an unlocked multiplier, allowing overclocking, whereas the Ryzen AI 9 PRO 465 is locked. The 8940HX uses AMD Socket FL1, while the Ryzen AI 9 PRO 465 uses AMD Socket FP8.

The Verdict

The data clearly indicates that the AMD Ryzen 9 8940HX is the higher-performing processor for most workloads. It wins 9 of 11 head-to-head benchmarks, with its largest advantages in encryption, prime number calculation, and extended instructions. The 8940HX is the correct choice for users who need maximum multi-threaded throughput, including content creation, scientific computing, and database operations. Its 16-core, 32-thread configuration, combined with a 64 MB L3 cache, delivers a 58% multithread advantage and a 103.6% encryption advantage. The unlocked multiplier also allows for additional performance tuning.

The AMD Ryzen AI 9 PRO 465 is the better option for single-threaded performance, with a 7.1% lead in the single-thread benchmark. This makes it suitable for applications that depend on one fast core. Its 28-watt TDP also makes it more power-efficient for mobile devices. The Radeon 890M integrated graphics are a more capable GPU for light gaming and media tasks. However, the 8940HX is not far behind in single-threaded tests, and the Ryzen AI 9 PRO 465 cannot compete in any multi-threaded test.

For users who prioritize raw performance and multi-tasking, the Ryzen 9 8940HX is the clear winner. For those who value single-thread speed and lower power consumption, the Ryzen AI 9 PRO 465 is a reasonable alternative, but the overall performance gap heavily favors the 8940HX.
