AMD Ryzen 9 9850HX vs AMD Ryzen AI Max+ 392 Comparison

Where Each One Wins

The recorded benchmark data presents an unusually one-sided comparison. Across all 11 head-to-head PassMark tests, the AMD Ryzen 9 9850HX records the higher score, with the AMD Ryzen AI Max+ 392 finishing behind in every measured discipline. The database shows 11 wins for the 9850HX and zero wins for the AI Max+ 392.

The Ryzen 9 9850HX establishes its largest advantages in data compression where it scores 662,381 against 554,760, a 19.4% lead. Random string sorting follows closely with a 18% advantage (70,175 versus 59,487). Extended instructions show a 17.8% gap (53,817 versus 45,666), while data encryption delivers a 15.7% delta (32,139 versus 27,784). Floating point math sits at 15.6% (115,062 versus 99,548), and single-thread performance shows a 13.6% edge (4,461 versus 3,927). The multithread score favors the 9850HX by 14.4% (51,722 versus 45,231), integer math by 13.5% (172,943 versus 152,414), physics by 5.8% (3,054 versus 2,887), and prime number finding by a narrow 0.9% (323 versus 320).

The AI Max+ 392 does not win any category, but its closest margins come in prime number calculation and physics, suggesting the gap narrows in workloads that stress sustained computational throughput rather than memory bandwidth or latency-sensitive operations. The 9850HX's average benchmark score of 106,413 places it at the 97th percentile among all CPUs, while the AI Max+ 392's 90,541 average sits at the 96th percentile.

Architecture Differences

Both processors share the same Zen 5 architecture, 4 nm TSMC manufacturing process, and identical die size of 2x 70.6 mm². Each chip contains 12 cores and 24 threads with a 55 W TDP. The L1 cache is 80 KB per core on both, L2 cache is 1 MB per core on both, and each has 64 MB of L3 cache (the 9850HX lists it as 64 MB, the AI Max+ 392 as 64 MB shared). The transistor count is listed as 16,630 million for the 9850HX, while the AI Max+ 392 entry does not record a transistor figure.

The differences begin with codename and platform. The 9850HX belongs to the Fire Range family within the 9000 series, while the AI Max+ 392 comes from Strix Halo. The 9850HX uses AMD Socket FL1; the AI Max+ 392 uses AMD Socket FP11. Base clocks differ: 3.00 GHz for the 9850HX versus 3.20 GHz for the AI Max+ 392. Boost clocks reverse the order: 5.20 GHz for the 9850HX versus 5.00 GHz for the AI Max+ 392.

Memory architecture diverges substantially. The 9850HX supports DDR5 over a dual-channel bus with 89.6 GB/s bandwidth. The AI Max+ 392 uses LPDDR5X across a quad-channel bus with 256.0 GB/s, which is roughly 2.86 times the bandwidth of the 9850HX. Both support ECC memory. PCIe connectivity also differs: the 9850HX offers Gen 5 with 28 CPU lanes, while the AI Max+ 392 provides Gen 4 with 16 CPU lanes.

Integrated graphics separate the two clearly. The 9850HX carries a Radeon 610M, while the AI Max+ 392 integrates a Radeon 8060S. The multiplier is unlocked on the 9850HX but locked on the AI Max+ 392. Release dates differ by one year: the 9850HX entered production status with a January 5, 2025 release date, while the AI Max+ 392 lists January 5, 2026. The part numbers are 100-000001366 for the 9850HX and 100-000001979 for the AI Max+ 392.

Head-to-Head Benchmarks

The largest single margin in the head-to-head set is data compression. The 9850HX scores 662,381 against the AI Max+ 392's 554,760, giving a 19.4% advantage. This workload typically exercises integer throughput, cache hierarchy, and memory latency, all areas where the 9850HX's higher boost clock and dual-channel DDR5 configuration appear to deliver measurable benefit.

Random string sorting shows an 18% gap (70,175 versus 59,487). This test is sensitive to memory access patterns and pointer chasing; the 9850HX's advantage here indicates its memory subsystem handles random access more efficiently despite the AI Max+ 392's much higher theoretical bandwidth. Extended instructions follow at 17.8% (53,817 versus 45,666), reflecting the 9850HX's stronger AVX-class execution throughput.

Data encryption delivers a 15.7% delta (32,139 versus 27,784). Floating point math shows a 15.6% gap (115,062 versus 99,548). The multithread score favors the 9850HX by 14.4% (51,722 versus 45,231), confirming that even with identical core and thread counts, the 9850HX extracts more parallel performance from its 24 threads. Integer math trails at 13.5% (172,943 versus 152,414), and single-thread performance shows a 13.6% delta (4,461 versus 3,927), consistent with the 9850HX's higher 5.20 GHz boost ceiling.

The physics test narrows the gap to 5.8% (3,054 versus 2,887), and prime number finding shows only a 0.9% difference (323 versus 320). These two results suggest that in workloads dominated by simple arithmetic loops with minimal memory traffic, the AI Max+ 392's higher base clock of 3.20 GHz partially compensates for its lower boost clock. The average benchmark score difference is 15,872 points, with the 9850HX at 106,413 and the AI Max+ 392 at 90,541. The 9850HX's nearest rival is the Intel Xeon w7-3555 at 106,192 (0.2% behind), while the AI Max+ 392's nearest rival is the Intel Xeon 654 at 90,717 (0.2% ahead).

The Verdict

The data supports a straightforward selection for raw CPU compute: the AMD Ryzen 9 9850HX outperforms the AMD Ryzen AI Max+ 392 in every recorded benchmark. Users prioritizing multi-threaded throughput, single-thread responsiveness, or memory-latency-sensitive workloads should choose the 9850HX based on its 11 wins and consistently double-digit deltas in most categories.

The AI Max+ 392 offers a different trade-off that the benchmark scores do not capture. Its quad-channel LPDDR5X memory bus delivers 256.0 GB/s, nearly three times the 9850HX's 89.6 GB/s. The integrated Radeon 8060S is a substantially more capable GPU than the Radeon 610M. The AI Max+ 392 also runs at a higher base clock (3.20 GHz versus 3.00 GHz) and uses a lower-power memory type typical of compact mobile platforms. Its locked multiplier and Gen 4 PCIe with 16 lanes indicate a design aimed at integrated systems rather than user-overclocked notebooks.

For pure processor performance, the 9850HX wins every measured category. For workloads that depend on memory bandwidth or the integrated GPU, the AI Max+ 392's platform-level features could matter more than its CPU benchmark deficits. The 9850HX's 97th percentile ranking versus the AI Max+ 392's 96th percentile confirms the small but consistent overall performance gap. The 9850HX also launched one year earlier and uses a socket (FL1) associated with the Fire Range platform, while the AI Max+ 392 belongs to the Strix Halo generation on Socket FP11.
