AMD Ryzen 9 9850HX vs AMD Ryzen AI 5 PRO 440 Comparison

Head-to-Head Benchmarks

The recorded data gives the AMD Ryzen 9 9850HX a clean sweep: 11 benchmark wins against zero for the AMD Ryzen AI 5 PRO 440. The gap is substantial across every workload category, but the magnitude varies significantly between multi-threaded and single-threaded tests.

The largest delta appears in passmark_find_prime_numbers, where the Ryzen 9 9850HX scores 323 against 77, a 319.5% advantage. This test is highly sensitive to raw integer throughput and memory latency, and the result underscores how far apart these two mobile processors sit in computational density. Extended instructions follow closely: 53817 versus 18456, a 191.6% delta. That workload exercises AVX-class instruction paths, and the Ryzen 9 9850HX more than doubles the output of the Ryzen AI 5 PRO 440.

Floating-point math shows a 168% delta (115062 versus 42934), while integer math lands at 162.1% (172943 versus 65991). Physics simulation, a heavily threaded workload, shows a 172.9% gap (3054 versus 1119). Data encryption delivers a 158.8% delta (32139 versus 12418), and data compression records 158.3% (662381 versus 256420). Random string sorting, another memory-and-thread-bound test, shows 70175 versus 27252, a 157.5% delta.

The multithread score itself is 51722 for the Ryzen 9 9850HX versus 21054 for the Ryzen AI 5 PRO 440, a 145.7% gap. This is the headline metric for parallel workloads, and it confirms that the 12-core part operates in a different tier entirely.

The narrowest margin is in single-threaded performance. The passmark_single_thread score shows 4461 for the Ryzen 9 9850HX versus 3785 for the Ryzen AI 5 PRO 440, a 17.9% delta. Both chips share the Zen 5 architecture and the same 4 nm TSMC process, so the per-core efficiency is similar; the difference comes down to boost clock and cache behavior. The Ryzen 9 9850HX boosts to 5.20 GHz against 4.80 GHz for the Ryzen AI 5 PRO 440, and its larger L3 allocation reduces memory stalls on single-threaded code.

Average benchmark scores reinforce the hierarchy. The Ryzen 9 9850HX posts an average of 106413, placing it in the 97th percentile of all CPUs in the database. The Ryzen AI 5 PRO 440 averages 41208, which lands in the 87th percentile. The nearest rivals for the Ryzen 9 9850HX include the Intel Xeon w7-3555 at 106192 (0.2% behind), the Intel Xeon 6521P at 105845 (0.5% behind), and the AMD EPYC 8324P at 103329 (3% behind); the Intel Xeon w7-2595X sits 2.1% ahead at 108663. The Ryzen AI 5 PRO 440 trades blows with the Intel Core Ultra 7 356H at 41215 (0% delta), the Intel Core Ultra 7 366H at 41263 (0.1% ahead), and the Intel Core Ultra X7 358H at 40967 (0.6% behind), while the AMD Ryzen 9 5900X sits 0.4% ahead at 41376.

Architecture Differences

Both processors are built on Zen 5 and manufactured by TSMC on a 4 nm node, but the similarity ends there. The Ryzen 9 9850HX belongs to the 9000 series with the Fire Range codename, while the Ryzen AI 5 PRO 440 carries the Gorgon Point codename and the Ryzen AI PRO 400 generation label, which mixes Zen 5 and Zen 5c cores.

Core counts diverge sharply. The Ryzen 9 9850HX provides 12 cores and 24 threads, while the Ryzen AI 5 PRO 440 provides 6 cores and 12 threads. That doubling of cores and threads is the primary driver of the multithreaded deltas. Clock speeds follow the same direction: the Ryzen 9 9850HX has a 3.00 GHz base clock and a 5.20 GHz boost clock, while the Ryzen AI 5 PRO 440 runs at 2.00 GHz base and 4.80 GHz boost. The 9850HX also carries an unlocked multiplier, whereas the AI 5 PRO 440 is locked.

Cache allocation is a major differentiator. Both chips use 80 KB of L1 per core and 1 MB of L2 per core, but the L3 cache tells the story: the Ryzen 9 9850HX has 64 MB of L3, while the Ryzen AI 5 PRO 440 has 8 MB. That eightfold difference in shared cache materially affects workloads with large working sets, including compression, encryption, and extended-instruction loops.

The physical packages differ as well. The Ryzen 9 9850HX reports a die size of 2x 70.6 mm² with 16,630 million transistors, while the Ryzen AI 5 PRO 440 shows a single 195 mm² die with no transistor figure recorded. The 9850HX uses AMD Socket FL1, and the AI 5 PRO 440 uses AMD Socket FP8. The 9850HX draws a 55 W TDP versus 28 W for the AI 5 PRO 440, which explains part of the performance gap but also positions the AI 5 PRO 440 for lower-power chassis.

Memory support is comparable in bandwidth: both support dual-channel memory at 89.6 GB/s, and both support ECC. The Ryzen 9 9850HX lists DDR5, while the Ryzen AI 5 PRO 440 supports both DDR5 and LPDDR5X. PCIe connectivity differs: the Ryzen 9 9850HX provides Gen 5 with 28 CPU lanes, while the Ryzen AI 5 PRO 440 provides Gen 4 with 16 CPU lanes. Integrated graphics also differ: the 9850HX uses the Radeon 610M, while the AI 5 PRO 440 uses the Radeon 840M. The AI 5 PRO 440 has a later release date of 2026-01-04 compared to 2025-01-05 for the 9850HX.

Where Each One Wins

The Ryzen 9 9850HX wins every recorded benchmark, so the practical question is where the Ryzen AI 5 PRO 440 remains competitive. The single-threaded delta of 17.9% is the closest margin in the dataset. For applications that depend on per-core responsiveness rather than parallel throughput, the AI 5 PRO 440 is far closer to the 9850HX than any multi-threaded metric suggests. Its 4.80 GHz boost clock and Zen 5 cores keep it within reach for lightly threaded tasks.

The Ryzen AI 5 PRO 440 also draws less power at 28 W versus 55 W, and its integrated Radeon 840M is a newer graphics solution than the Radeon 610M in the 9850HX. For systems where sustained CPU load is rare and GPU output matters more, the AI 5 PRO 440 holds an advantage in platform characteristics, not in CPU benchmark scores. The database does not record iGPU benchmark scores for either chip, so the comparison rests on the listed specifications.

The Ryzen 9 9850HX is the clear pick for compute-heavy mobile workloads. Its multithread score of 51722 versus 21054 represents a 145.7% advantage, and its L3 cache of 64 MB versus 8 MB gives it a structural edge in data-heavy loops. The 97th percentile placement versus 87th percentile also confirms that the 9850HX competes against workstation-class silicon, not mainstream mobile parts.

The Verdict

The data positions the AMD Ryzen 9 9850HX as a high-end mobile processor that competes with workstation Xeon parts. Its average score of 106413 puts it within 0.2% of the Intel Xeon w7-3555, and its nearest rivals are all Xeon or EPYC models. The 12 cores, 24 threads, 64 MB L3, and 5.20 GHz boost clock deliver a 145.7% multithread advantage over the Ryzen AI 5 PRO 440, and the 55 W TDP reflects that performance ambition.

The AMD Ryzen AI 5 PRO 440 is a mainstream mobile part aimed at efficiency and platform balance. Its 28 W TDP, hybrid Zen 5 and Zen 5c core arrangement, and 8 MB L3 cache keep it in a lower performance tier, but its 87th percentile standing is still respectable for a 6-core part. The closest rivals are Intel Core Ultra 7 and Ultra X7 models, with deltas of no more than 0.6%, indicating that the AI 5 PRO 440 is well matched against contemporary mid-range mobile silicon.

Users who need maximum CPU throughput in a laptop should choose the Ryzen 9 9850HX. The 158.3% delta in data compression, 158.8% in encryption, and 191.6% in extended instructions show that heavily threaded and vectorized workloads benefit enormously from the extra cores, cache, and clock headroom. Users who prioritize lower power draw and a newer integrated GPU should consider the Ryzen AI 5 PRO 440, since its 17.9% single-thread deficit is the only benchmark gap below 100%, and its platform characteristics are better suited to thinner, cooler systems.
